Creating Web Pages with HTML, 3e 4
Working with CGI Scripts
• HTML supports tags for creating forms, however, it does
not process the information.
• Use CGI (Common Gateway Interface) script to process
• CGI script runs on the Web server and receives data from a
form and uses it to perform a set of tasks.
• Web page designers may not be able to create or edit CGI
– Internet Service Providers (ISPs) and universities may provide CGI
scripts that their customers and student can use on their Web sites,
but which they cannot directly access or modify
Creating Web Pages with HTML, 3e 5
• Among the many things CGI scripts made possible are:
– online database containing customer information
– catalogues for ordering and purchasing items online
– databases containing product support information
– determining the number of times a Web page has been
– server-side image maps
– message boards for online discussion forums
– e-mail for discussion groups
Creating Web Pages with HTML, 3e 6
CGI Script Restrictions
• There are several reasons to restrict direct access to CGI
– CGI scripts are actually running a program directly on the
– security risks from computer hackers
– drain on system resources caused by large numbers of
programs running simultaneously
• System administration are understandably careful to
maintain strict control over their servers and systems.
Creating Web Pages with HTML, 3e 7
CGI Scripts and Computer Languages
• CGI scripts can be written in a variety of different computer
languages. Some of the most commonly used languages are:
– The UNIX shell
– Visual Basic
• The computer language used depends on the Web server.

Creating Web Pages with HTML, 3e 9
Form Control Elements
• Control elements that are commonly used:
– text boxes for text and numerical entries
– selection lists for long lists of options, usually appearing in a
drop-down list box
– radio buttons, also called option buttons, to select a single
option from a predefined list
– check boxes to specify an item as either present or absent
– groups boxes to organize form elements
– text areas for extended entries that can include several lines
– buttons that can be clicked to start processing the form
Creating Web Pages with HTML, 3e 10
Form Control Elements Continued
• Each control element in which the user can enter
information is called a field.
• Information entered into a field is called the field value, or
simply the value.
• In some fields, users are free to enter anything they choose.
• Other fields, such as selection lists, limit the user to a
predefined list of options.
Creating Web Pages with HTML, 3e 11
The <form> Tag
• The <form> tag identifies the beginning and end of a form.
• A single page can include several different forms, but you
cannot nest one form inside another.
• The general syntax of the <form> tag is:
form elements and layout tags
• Between the <form> and </form> tags, place the various
tags for each of the fields in the form.
• Use standard HTML tags to specify the form’s appearance.
Creating Web Pages with HTML, 3e 12
The <form> Tag Continued
• A single Web page can contain multiple forms, the
<form> tag includes the name attribute.
• The name attribute identifies each form on the page.
• The name attribute is also needed for programs that
retrieve values from the form.

Creating Web Pages with HTML, 3e 17
Working with Text Boxes
• Text boxes are created using the <input> tag.
• The general syntax is:
<input type=“type” name=“name” id=“id”>
– type specifies the type of input field
– name and id attributes identifies the input field for the CGI
• To create a text box, you would enter the tag:
• If the type attribute is not included, the Web browser
assumes, by default, that you want to create a text box.
Creating Web Pages with HTML, 3e 18
The name and id Attribute
• The name and id attributes of the <input> tag identifies
the input field for the CGI script.
• The name attribute represents the older standard, but it is
deprecated in HTML 4.01, however, some CGI scripts still
recognize only the name attribute
• The newest standard uses the id attribute.
• The id attribute is required, if a form contains form labels.
• It is best to duplicate the information by using both the
name and id attributes.
Creating Web Pages with HTML, 3e 19
Creating a Text Box
• To create a text box, use the following HTML code:
<input name=“name” id=“id” value=“value”
– name and id attributes identify the field
– value attribute assigns a default value to the text box
– size attribute defines the width of the text box in number
– maxlength attribute defines the maximum number of
characters allowed in the field

Creating Web Pages with HTML, 3e 21
CGI Script Names
• Some CGI scripts require a particular field or groups of
– for example, a CGI script whose purpose is to e-mail form
values to another user might require a field named “email”
that contains the e-mail address of the recipient
• Before using a CGI script, check the documentation for
any requirements and then design your form accordingly.
• Case is important in field names.
– a field named “email” might not be interpreted by the CGI
script in the same way as a field named “EMAIL”

Controlling the Size of a Text Box
• By default, all text boxes are 20 characters wide.
• The syntax for changing the size of a text box is:
– value is the size of the text box in characters

Creating Web Pages with HTML, 3e 26
Setting the Maximum Length
for Text Input
• Setting the width of a text box does not limit the number of
characters the box can hold.
– if a user enters text longer than the box’s width, the text scrolls
to the left
– the user cannot see the entire text, but all of it is sent to the
CGI script for processing
• The syntax for setting the maximum length for field input is:
– value is the maximum number of characters that can be stored
in the field

Specify the Maximum Length
for a Field

Creating Web Pages with HTML, 3e 28
Setting a Default Value for a Field
• When the same value is entered into a field, it may
make sense to define a default value for a field.
• Default values can save time and increase
accuracy for users of a Web site.
• To define a default value, use the following
– value is the default text or number that is displayed in
Creating Web Pages with HTML, 3e 29
Defining a Default Value for a Field
If customers from countries other than the United States use this Web form,
they can remove the default value by selecting the text and pressing the Delete key.
Creating Web Pages with HTML, 3e 30
Creating a Password Field
• A password field is a text box in which the characters
typed by the user are displayed as bullets or asterisks i.e.
• The syntax for creating a Password field is:
• Using a password field should not be confused with having
a secure connection.
• The password itself is not encrypted.
• The password field only acts as a mask for a field entry as
it is entered.
Creating Web Pages with HTML, 3e 31
Working with Form Labels
• HTML allows you to formally link a label with an
associated text element for scripting purposes.
• The syntax for creating a form label is:
<label for=“id”>label text</label>
– id is the value of the id attribute for a field on the form
– label text is the text of the label
– you must bind the label to the id attribute of the field and not
the name attribute
Creating Web Pages with HTML, 3e 32
Working with Form Labels
• Labels can simplify the data entry process by allowing a
user to click on either the control element or the element’s
label to enter data.
• Labels allow users to write scripts to modify their content
for interactive forms.
• The <label> tag is part of the HTML 4.0 specifications,
however, it is not currently supported by Netscape.
• The Netscape browser, and versions of the Internet
Explorer browser prior to 4.0, ignore the <label> tag,
but still display the label text.

Creating a Selection List
• A selection list is a list box from which a user selects a
particular value or set of values.
• Selection lists are good to use when there is a fixed set of
• Selection lists help prevent spelling mistakes and
• A selection list is created using the <select> tag.
• The <option> tag is used to specify individual selection

items in the selection
Creating Web Pages with HTML, 3e 36
Using a Selection List
list might look
depending on the
Creating Web Pages with HTML, 3e 37
Using the <select> XP
and <option> Tags
• The general syntax for the <select> and <option> tags is:
<select name=“name” id=“id”>
– name and id attribute identify the selection field
– each <option> tag represents an individual item in the selection
– the text in the selection list is indicated by the text in
item1, item2, and so forth
• The <option> tag is a one-sided tag.
Creating Web Pages with HTML, 3e 38
Modifying the Appearance
of a Selection List
• HTML provides several attributes to modify the
appearance and behavior of selection lists and options.
• By default, the <select> tag displays one option from
the selection list, along with a list arrow to view additional
• The number of options displayed can be modified with the
• The syntax of the size attribute is:
Creating Web Pages with HTML, 3e 39
Modifying the Appearance
of a Selection List Continued
– value is the number of items that the selection list
displays in the form
– by specifying a value greater than 1, the selection list
changes from a drop-down list box to a list box
– if the size attribute is equal to the number of options in
the selection list, the scroll bar is either not displayed or
Creating Web Pages with HTML, 3e 40
Selection Lists with
Different Size Values

selection lists with
values. size = "1" size = "4"
size = "7" size = "9"
Creating Web Pages with HTML, 3e 41
Making Multiple Selections
• When using multiple selections, users are not limited to a
single selection from a selection list.
• Adding the multiple attribute to the <select> tag allows
multiple selections from a list.
• The syntax for this attribute is:
• A common method to make multiple selections from a
selection list is to hold down a specific key while making
Creating Web Pages with HTML, 3e 42
Making Multiple Selections Continued
• The Windows operating system, multiple selections can be
made as follows:
– for noncontiguous selections, press and hold the Ctrl key
while you make your selections
– for a contiguous selection, select the first item, press and
hold the Shift key, and then select the last item in the range
• Check and verify that the CGI scripts used are designed to
handle multiple selection lists.
Creating Web Pages with HTML, 3e 43
Working with Option Values
• By default, a form sends the values that are displayed
in the selection list to the CGI script.
• Instead of sending an entire text string, an
abbreviation or code can be sent to the CGI script.
• Specify the value that is sent to the CGI script with the
• Use the selected attribute to specify which item in the
selection is selected, or highlighted, when the form is
Creating Web Pages with HTML, 3e 44
Working with Option Groups
• The most recent releases of HTML allows you to
organize selection lists into distinct groups called
• The syntax for creating an option group is:
– label is the label assigned to the option group
– the text for the label appears in the selection list above
each group of items but is not a selectable item from the
Creating Web Pages with HTML, 3e 45
Internet Explorer and Netscape versions prior to 6.0 display
the selection list without the group labels.
a single group label
group a single option
Creating Web Pages with HTML, 3e 46
Working with Radio Buttons
• Radio buttons display a list of choices from which a user
makes a selection.
• Only one radio button can be selected at a time.
• The syntax to create a radio button is:
<input type=“radio” name=“name” id=“id”
– name identifies the field containing the radio button
– id attribute identifies the specific option. Only required if you
intend to use a field label with the radio button
– value attribute indicates the value sent to the CGI script, if that
radio button is selected by the user
Creating Web Pages with HTML, 3e 47
Radio Buttons Continued
• The name attribute must be included, because it
groups distinct radio buttons together.
– selecting one radio button in the group automatically
deselects all of the other radio buttons in that group
• Insert descriptive text next to the button.
• Enclose text within a label tag to allow the user to
select the radio button or label.
Creating Web Pages with HTML, 3e 48
Creating Radio Buttons
This figure shows an example of HTML code that creates radio buttons for party affiliations.
In this sample code, the value sent to the CGI script does not match the field label.
If the user selects the Republican radio button, the value “gop”
is sent to the CGI script paired with the field name “party.”
Creating Web Pages with HTML, 3e 49
Selection Lists vs. Radio Buttons
• If you have a long list of options, use a selection
• If you want to allow users to select more than one
option, use a selection list with the multiple
• If you have a short list of options, and only one
option is allowed at a time, use radio buttons.
Creating Web Pages with HTML, 3e 50
Creating a Group Box
• A group box labels an entire collection of radio
• A group box is a box placed around a set of fields
that indicates that they belong to a common group.
• The syntax for creating a group box is:

Group Box Size
• There is no attribute to control the size of a group box.
• The box’s height will be large enough to accommodate the
fields and labels in the field set.
• The width is the width of whatever space remains on the
• To set the width to a specific value use a table cell to place
the group box and set the width of the cell.
– group boxes cannot extend across table cells; all of the fields
in the field set must be placed within a single cell
Creating Web Pages with HTML, 3e 54
Working with Check Boxes
• A check box is either selected or not, there is only one check box
• Check boxes are created using the following syntax:
<input type=“checkbox” name=“name” id=“id”
– name and id attribute identify the check box
– the value attribute specifies the value that is sent to the CGI script
when the check box is selected
• The <input> tag for a check box does not display any text.
• Check boxes are not selected by default.
– to do this, add the checked attribute to the <input> tag
Creating Web Pages with HTML, 3e 55
Adding Check Boxes
This figure shows different check boxes. The user can click either the check box or
the label associated with the check box to select and deselect.

Creating a Text Area
• To create a larger text area for a text box, use the
<textarea name=“name” id=“id” rows=“value”
cols=“value”> default text </textarea>
– rows and cols attributes define the dimensions of the text
– the rows attribute indicates the number of lines in the text
• Default text can be specified in the text box when
the form is initially displayed.

Creating Web Pages with HTML, 3e 59
Wrap Attribute Values
The text entered in a text area wraps to the next line when it exceeds the width of the
box. To control how a browser wraps text to a new line use the wrap attribute.
This figure shows the three possible wrap options.
Creating Web Pages with HTML, 3e 60
The wrap Attribute for Text
• Set the value of the wrap attribute to either “soft” or
“hard” to allow text to wrap within the text box.
– the “hard” setting preserves any line wrapping that takes place in
the text box and the “soft” setting does not.
• If no value for the wrap attribute is specified, a value of
“soft” is used.
• For comment fields, use the <textarea> tag with the
wrap attribute set to “soft” so that the user’s comments
wrap to the next line in the box.

Creating Web Pages with HTML, 3e 62
Creating Form Buttons
• Another type of control element is one that
performs an action. In forms, this is usually done
with a button.
• Buttons can be clicked to:
– run programs
– submit forms
– reset the form to its original state
Creating Web Pages with HTML, 3e 63
Creating a Push Button
• One type of button, called a push button, is
created using the <input> tag as follows:
<input type=“button” value=“text”>
– text is the text that appears on the button
• By themselves, push buttons perform no actions in
the Web page.
• To create an action, write a script or program that
runs automatically when the button is clicked.
Creating Web Pages with HTML, 3e 64
Creating Submit and Reset Buttons
• A submit button is a button that submits the form
to the CGI script for processing.
• A reset button resets the form to its original
• The syntax for creating these two buttons is:
<input type=“submit” value=“text”>
<input type=“reset” value=“text”>
– value attribute defines the text that appears on the
Creating Web Pages with HTML, 3e 65
The name and value Attributes
• The name and value attributes can be used for
push, submit, and reset buttons.
• Use these attributes when the form contains
multiple buttons and a program that processes the
form needs to distinguish one button from another.
– for example, a Web page advertising a shareware
program might include three buttons:
• one used to download the program
• another used to retrieve information
• the third to cancel the form
Creating Web Pages with HTML, 3e 66
Creating a Form Button
The figure shows HTML tags for buttons that download a program,
retrieves information, and resets the form to its original values.
Creating Web Pages with HTML, 3e 67
with the <button> Tag
• Buttons created with the <input> tag do not allow the Web page
designer to control the appearance of the button.
• For greater artistic control over the appearance of the button, use the
• The syntax of the <button> tag is:
<button name=“name” value=“value”

Creating File Buttons
• A file button is used to select files so that their
contents can be submitted for processing to a CGI
• The contents of the file are not displayed--only the
• A programmer can then use that information to
retrieve a file and use it for whatever purpose is
required by the script.

“report.doc.” Choose File dialog box
3. The filename and location
are automatically placed in
the text box
Creating Web Pages with HTML, 3e 71
Creating Image Fields
• Inline images can act like submit buttons, so that when the user clicks the
image, the form is submitted.
• The syntax for this type of control element is:
<input type=“image” src=“URL” name=“text”
– URL is the filename and location of the inline image
– name attribute assigns a name to the field
– value attribute assigns a value to the image
• When the form is submitted to the CGI script, the coordinates of where the
user clicked are attached to the image’s name and value in the format:

Creating Web Pages with HTML, 3e 73
Working with Hidden Fields
• A hidden field is added to the form but not displayed in the
• Because the field is hidden, it can be placed anywhere
between the opening and closing <form> tags.
• The syntax for creating a hidden field is:
<input type=“hidden” name=“name”
• Place all hidden fields in one location to make it easier to
read and interpret the HTML code.
• Include a comment describing the purpose of the field.
Creating Web Pages with HTML, 3e 74
Adding a Hidden Field
This figure shows
an example of the
hidden field code.
Creating Web Pages with HTML, 3e 75
Working with Form Attributes
• To specify where to send the form data and how to
send it add the following attributes to the <form>
<form action=“URL” method=“option”
– URL specifies the filename and location of the CGI script
that process the form
– method attribute specifies how your Web browser sends data
to the CGI script
– enctype attribute specifies the format of the data stored in the
Creating Web Pages with HTML, 3e 76
The method Attribute
• There are two possible values for the method attribute: “get” or
– the “get” method (the default) packages the form data by
appending it to the end of the URL specified in the action attribute
– the “post” method sends form data in a separate data stream,
allowing the Web server to receive the data through what is called
– the “post” method is considered the preferred way of sending data
to a Web server
– The “post” method is also safer, because some Web servers limit
the amount of data sent via the “get” method and will truncate the
URL, cutting off valuable information
Creating Web Pages with HTML, 3e 77
The enctype Attribute
• The exact meaning of the enctype attribute is a technical
• The default enctype value is “application/x-www-form-
• Another enctype value that is often used is
“multipart/form-data,” which allows the form to send
files to the Web server along with any form data.
• The most basic way of encoding data is to use
“text/plain,” which encodes the data as simple text.
Creating Web Pages with HTML, 3e 78
Specifying Where and How
to Send Form Data
This figure shows the CGI script that processes the form is located at the URL
http://www.langear.com/cgi/mailer (a fictional address) and uses the “post” method.
Creating Web Pages with HTML, 3e 79
The Web browser
presents a page, an
example of which is
shown in this figure,
displaying the name
of each field in the
form and the value
assigned to it. At the
same time, the CGI
script formats a mail
message to be sent to
the address you
Creating Web Pages with HTML, 3e 80
Using the “mailto” Action
• Use the “mailto” action to send form information via e-
mail without using a CGI script.
• This action accesses the user’s own e-mail program and uses
it to mail form information to a specified e-mail
address, bypassing the need for using CGI scripts on a Web
• The syntax of the “mailto” action is:
– e-mail_address is the e-mail address of the recipient of
Creating Web Pages with HTML, 3e 81
Using the “mailto” XP
• Not all browsers support the “mailto” action.
– for example, versions of Internet Explorer earlier than
4.0 and Netscape Navigator 3.0 do not
• Another concern is that messages sent via the
“mailto” action are not encrypted for privacy.
• The recipient’s email address is revealed to the user.

Creating Web Pages with HTML, 3e 83
Specifying the Tab Order
• Users navigate through a Web form using the Tab key.
– the Tab key moves the cursor from one field to another in the order
that the field tags are entered.
• Add the tabindex attribute to any control element in the
form to specify the tab order.
• With each element assigned a tab index number, the cursor
moves through the fields from the lowest index number to
– for example, to assign the tab index number “1” to the fname field,
enter the code: <input name=“fname” tabindex=“1”>
Creating Web Pages with HTML, 3e 84
Tab Order and Browsers
• Browsers that do not support the tab order feature
simply ignores the tabindex attribute and
continues to tab to the fields in the order that they
appear in the HTML code.
Creating Web Pages with HTML, 3e 85
Specifying an Access Key
• An access key is a single key that you type in conjunction
with the Alt key for Windows users or the Command key for
Macintosh users, to jump to one of the control elements in the
• Add the accesskey attribute to any of the control elements to
create an access key.
• To create an access key for the lname field, enter the
following code: <input name=“lname”
– if a user types Alt+l (or Command+1 for Macintosh users), the control
element for the lname field is selected
Creating Web Pages with HTML, 3e 86
Specifying an Access Key Continued
• Use letters that are not reserved by the browser.
– for example, Alt_f is used by Internet Explorer to access the
• When an access key is used, provide some visual clue about
the key’s existence.
