This document discusses Nette, a popular PHP framework for web development. It provides an overview of key Nette features like the RobotLoader, forms, templating with Latte, dependency injection, routing, AJAX, debugging and error handling, and the database layer. The document also mentions that components and controls allow for reusable code, signals, and flash messages.

1. NETTE FRAMEWORK
A POPULAR TOOL FOR PHP WEB DEVELOPMENT...
(ON SERVER)
Adam Štipák (@new_POPE)

2. CREATED BY
@DAVIDGRUDL

3. 1.4.2014

4. DIED!

5. WELCOME
NETTE "SMALL PROJECTS"!

6. I WILL TALK ABOUT NETTE
AS IF IT WERE ONE PACKAGE

7. ROBOTLOADER
$loader=newNetteLoadersRobotLoader;
$loader->addDirectory('app');
$loader->addDirectory('libs');
$loader->setCacheStorage(...);
$loader->register();
netterobots.txt
Disallow:/Zend

8. FORMS
validate sentdataboth client-side (JavaScript) and server-side
provide high levelof security
multiple render modes
translations, i18n

9. FIRST FORM
$form=newForm;
$form->addText('name','Name:');
$form->addText('surname','Surname:')
->setRequired('Pleasefillyoursurname.');
if($form->isSubmitted()&&$form->isValid()){
echo'Formwassubmittedandpassedvalidation';
$values=$form->getValues();
dump($values);
}
<scriptsrc="netteForms.js"></script>

10. PRESENTER FORMS
Presenter
protectedfunctioncreateComponentSignInForm()
{
$form=newNetteApplicationUIForm;
$form->addText('name','Name:');
$form->addPassword('password','Password:');
$form->addSubmit('login','Login');
$form->onSuccess[]=array($this,'signInFormSubmitted');
return$form;
}
functionsignInFormSubmitted($form)
{
//calledwhenformissubmittedandsuccessfullyvalidated
}
Latte
{controlsignInForm}

11. MULTIPLE RENDER MODES
{formsignForm}
<table>
<trclass="required">
<th>{labelname/}</th>
<td>{inputname}</td>
</tr>
...
</table>
{/formsignForm}
<table>
<trclass="required">
<th><labelfor="frm-name"></th>
<td><inputcols=40n:name="name"></td>
</tr>
<table>

12. TEMPLATING (LATTE)
macros &helpers
user-defined macros
blocks &inheritance
Context-Aware Escaping

13. MACROS & HELPERS
<uln:if="$items">
{foreach$itemsas$item}
<liid="item-{$iterator->counter}">{$item|capitalize}</li>
{/foreach}
</ul>
macroin braces, for example {foreach …}
n:macro, for example n:if="…"

14. USER-DEFINED
Macro
$latte=newNetteLatteEngine;
$set=newNetteLatteMacrosMacroSet($latte->compiler);
$set->addMacro('if',function($node,$writer){
return$writer->write('if(%node.args):');
},'endif');
Helper
$template->registerHelper('shortify',function($s){
returnmb_substr($s,0,10);
});
<p>{$text|shortify:100}</p>

15. BLOCKS & INHERITANCE
foo.latte
{blockfoo}FOO{/block}
<divn:block="foo">FOO</div>
bar.latte
{extends'foo.latte'}
{blockfoo}BAR{/block}<!--n:block-->

16. CONTEXT-AWARE ESCAPING
<div>{$foo}</div>
<scripttype="text/javascript">
</script>
alert({$foo});
arr={$array};

17. DI, DI EXTENSIONS

18. DI
config.neon
services:
foo:Foo
bar:Bar
PHP
classBar{
function__construct(Foo$foo){//$fooisinstanceofFoo}
}

19. DI CONTAINER EXTENSIONS
config.neon
extensions:
blog:MyBlogExtension
blog:#samenameasyourextension
postsPerPage:10
comments:FALSE
PHP
classMyBlogExtensionextendsNetteDICompilerExtension{
publicfunctionloadConfiguration(){
$config=$this->getConfig();
//array(2)['postsPerPage'=>10,'comments'=>FALSE]

20. COMPONENTS &
CONTROLS
reusable code
signals
flash messages

21. COMPONENT
useNetteApplicationUIControl;
classPollControlextendsControl
{
...
}
publicfunctionrender()
{
$template=$this->template;
$template->setFile(dirname(__FILE__).'/PollControl.latte');
$template->param='somevalue';
$template->render();
}

22. SIGNALS
In component
$url=$this->link('click!',$x,$y);
<an:href="click!$x,$y">...</a>

23. FLASH MESSAGES
component
publicfunctiondeleteFormSubmitted(Form$form){
...deleterecordusingmodel...
//passflashmessage
$this->flashMessage('Itemwasdeleted.');
$this->redirect(...);//andredirect
}
template
{foreach$flashesas$flash}
<divclass="flash{$flash->type}">{$flash->message}</div>
{/foreach}

24. ROUTING
Two wayconversion!
SimpleRouter
Route

25. TWO WAY CONVERSION
NetteHttpIRequest(includesURL)->NetteApplicationRequest
NetteApplicationRequest->absoluteURL
template
{linkFoo:bar1}->/foo/bar/1
{linkFoo:1}->/foo/default/1
{link:Module:Presenter:action}->/module/presenter/action

26. ROUTE
$route=newRoute(
'<presenter>/<action>[/<id>]',
'Homepage:default'
);
$route=newRoute(
'<presenter>/<action>[/<id>]',
array(
'presenter'=>'Homepage',
'action' =>'default'
)
);

27. ROUTE
$route=newRoute(
'<presenter=Homepage>/<action=default>',
array(
'action'=>array(
Route::FILTER_IN=>function($action){
returnstrrev($action);
},
Route::FILTER_OUT=>function($action){
returnstrrev($action);
},
),
)
);

28. AJAJAAJ AJAX
AJAX
snippets

29. AJAX
publicfunctionactionDelete($id){
if($this->isAjax()){
$this->payload->message='Success';
}
}
publicfunctionhandleClick($param){...}
$this->sendResponse(newJsonResponse(array('key'=>'value',...)));
publicfunctionhandlePool(...){
$this->redrawControl('header');
}

30. SNIPPETS
template
{snippetheader}Hello{$foo}!{/header}
<an:href="redrawHeader">Clickme!</a>
PHP
functionhandleRedrawHeader(){
$this->template->foo="World";
$this->redrawControl('header');
}

31. DEBUGGING AND ERROR
HANDLING
debugger bar
quicklydetectand correcterrors
logerrors

32. DEBUGGER BAR

33. TRACY

34. TRACY (PRODUCTION MODE)

35. LOG ERRORS
//Loganerror.
Debugger::log('Unexpectederror');
//Seterrormail.
Debugger::$email='admin@example.com';
//config.neon
common:
