Submit form with Ajax and jQuery without reloading page.pdfBe Problem Solver
Howdy friends, these days when people fill out a form on webpages they want an instant response!
So today in this article, we will show you how to submit the form with Ajax and jQuery without reloading the page. Yup! your form will be submitted but the webpage won’t refresh at all. To achieve this we will use our trusted jQuery and Ajax.
But Ajax is the key here!
Because it allows us to send and receive data without refreshing our webpage. Don’t worry I will explain it in detail in the next section.
You can use our code in combination with PHPMailer or Sendgrid to send emails as well. And send emails without any refresh or reload. Meaning with Ajax form submission without refresh, you can build applications where you can submit the form and display the results on the same page.
Anyway, let’s learn the basics first of jQuery and Ajax.
Are you interested in learning how to use APIs? No worries we will show you the complete API example in today’s article.
The two API examples are:
First – How to use a JSON API example to get weather information for our webpage. You can easily implement it in a mobile app too if need be. I assure you it is easy to do!
The second – we show you how to use our REST API example. Where we will insert, read, update and delete data with API. But before we proceed, check out our post where we explain 6 different methods to achieve knockout page scroll animation on your webpage with minimal coding!
Now let us tackle our first API example.
How to develop an API with PHP, JSON, and POSTMAN in 9 Steps.pdfBe Problem Solver
Looking to develop an API with PHP, JSON, and POSTMAN? Here are 9 steps to get you started. This guide will show you how to set up your development environment, create a PHP file to house your code, generate JSON data, and use POSTMAN to test your API.
CSS animations are a key aspect of modern website design. All websites whether simple HTML or dynamic, need an interactive UI design. And using page scroll animation CSS, we, developers can make the User Experience on the website pretty good.
Your website can end up feeling like a PSD screenshot without animation.
And most clients love CSS animation.
Developers adore CSS animations. Because unlike in the past when animations were cumbersome and required heavy JavaScript usage. Or relying on Gif images. And using third-party animation tools integration like Flash Player.
However, ever since the implementation of CSS3. We can deploy smooth animation, with zero lag and fast integration. You can even animate images and other elements without using JavaScript. But there is a catch.
But before moving to the next part. I recommend VS Code for this coding project. Check out why.
Let’s discuss it next.
Why only CSS animation is not enough?
CSS animations are amazing. Because of their simplicity to use and being ultra-fast. They liven up your website design. Makes your visitors interact more. And at the same time, your design feels more dynamic.
But even CSS animation cannot do everything. You need a little Javascript to make your CSS animation pop up.
When you combine the power of Javascript with CSS animation, your design will feel truly engaged with visitors. With help of different JS libraries, you can track the actions of visitors and trigger the likely animation they expect.
Let’s see how can we do page scroll animation:
1. With AOS Library
AOS also called Animate on Scroll is a fantastic library. It combines CSS animation with JS to give you fine-tuned control over scroll animation CSS.
Why do I recommend it? Answer is:
Super easy deployment with no dependency on other frameworks.
Can be integrated with existing projects.
Minimal javascript coding. So even a beginner can use it.
A ton of developers trust this library so if you get stuck, there is tremendous support.
7 out of 10 projects on sites like Themeforest and Monster Template use this library. Which how robust this library is and widely used.
Now let’s see how easy it is to use AOS in a project in my scroll animation codepen.
Let me describe what we did in simple steps:
1. First pasted our CDN link of the AOS library CSS file and hooked the JS file in the footer.
Note: I’m using Bootstrap 5 purely for quick design to show you how to use AOS in action. There is no dependence of AOS on Bootstrap itself.
2. Then we initialized the AOS in action.
In the end, I hope you learned some new methods of page scroll animation. Be sure to try one of them on your next project. If you are a beginner to Javascript, I recommend AOS no doubt. But if you are a veteran of web development and understand a fair amount of JS then any solution I describe will be superb for on-scroll animation CSS in web projects.
User login functionality in a website is a pretty simple but compulsory component. In all modern dynamic websites, the client asks for a login and admin panel so that they can do basic tasks.
Today I will give you a simple and clean-looking login system with PHP and MySQL. We will maintain the login tracking with PHP Sessions and let Bootstrap make us a clean UI Design.
Why PHP? Because despite being ancient. As some developers believe. PHP is fundamental to our web.
Around 81.7% of the websites on the web use PHP as their server-side language.
And why not PHP?
PHP powers famous CMS(Content Management System) like WordPress and Joomla. Open Source OOPs frameworks like Laravel and CodeIgniter. And numerous others.
Reason: PHP is simple and clean to write. Easy-to-understand and beginner-friendly. Vast community support and adaptability toward developer needs.
Let’s what will do in this simple project:
-User Login Design with Bootstrap 5
- PHP code for MySQL Database
- Logic to process the login request
- Throw errors if the wrong entry of login credentials
- Redirect to Admin if successful request
- Conclusion
Forging a clean UI with Bootstrap for User Login
First, we create index.php and write our UI design with the latest Bootstrap 5. We added Google Fonts Poppins for making our UI look eye-catching. Whenever possible, we relied on CDN links because it keeps our code lightweight and less resource intensive.
Next, we do simple CSS styling in our style.css file. To make our plain background something fun to look at, I have added a small background image in webp format. Also, coded in background color as a backup in the case of legacy browsers that do not support webp format yet.
Build and Hook up your MySQL database
Before we start preceding the actual PHP logic part. We need a database for keeping a record of our login users. And the best choice of course is MySQL–why because it’s free and open source like PHP. Not to mention very beginner friendly.
First, go to your PHPMyAdmin whether you’re working online or in the local environment. And set up your database with a relevant name to your project.
After the Database is created. Setup a table named users which has mainly four columns we need: id, email, password, and active. We can also execute the below SQL code in the PHPMyAdmin SQL tab and this will generate our table “users”.
Now, we can insert user login details by running the following SQL code. We are hard coding this now. But we can create a PHP code for the signup process later. First, we must deploy our user login system.
Next in line, we hook up a connection between MySQL and PHP:
Now our UI and database are set. Next, we tackle our User Login process head-on! Yay! I am excited!

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

Consistent toolbox talks are critical for maintaining workplace safety, as they provide regular opportunities to address specific hazards and reinforce safe practices.
These brief, focused sessions ensure that safety is a continual conversation rather than a one-time event, which helps keep safety protocols fresh in employees' minds. Studies have shown that shorter, more frequent training sessions are more effective for retention and behavior change compared to longer, infrequent sessions.
Engaging workers regularly, toolbox talks promote a culture of safety, empower employees to voice concerns, and ultimately reduce the likelihood of accidents and injuries on site.
The traditional method of conducting safety talks with paper documents and lengthy meetings is not only time-consuming but also less effective. Manual tracking of attendance and compliance is prone to errors and inconsistencies, leading to gaps in safety communication and potential non-compliance with OSHA regulations. Switching to a digital solution like Safelyio offers significant advantages.
Safelyio automates the delivery and documentation of safety talks, ensuring consistency and accessibility. The microlearning approach breaks down complex safety protocols into manageable, bite-sized pieces, making it easier for employees to absorb and retain information.
This method minimizes disruptions to work schedules, eliminates the hassle of paperwork, and ensures that all safety communications are tracked and recorded accurately. Ultimately, using a digital platform like Safelyio enhances engagement, compliance, and overall safety performance on site. https://safelyio.com/

Introduction
With the upcoming Halloween festive season in mind, we are bringing coding tutorials in
which we will convert image formats: PNG to JPG, JPG to PNG, and other image formats
such as GIFs to PNG, GIFs to JPG, or even JPEG to PNG or JPEG to GIFs, etc.
We power our image converter script with PHP. Because it provides built-in modules that will
allow us to achieve maximum results with minimum coding effort.
And as always, we are going to code this project in VS Code editor. Wanna know why?
Check this post out.
2. So without further talks, let’s jump into code. But before that check this demo out to know
what our final project looks like:
Demo of Image converter
File Structure
Since this project contains multiple files we will define a folder and file structure as well. As
usual, we will give you complete details. So the file will be as mentioned in the below picture:
Folder and File Structure PNG to JPG Image Converter
UI of Image Converter
Now that we are aware of all files we need to make, let’s start with the main file “index.php“.
And furthermore, we will divide our code for simplicity:
● “header.php“: this file contains only the basic details of the navigation bar of our JPG
to PNG image converter. And we will include this file in our “index.php“. With a
separate header file, we don’t need to code navigation-related changes to all files.
One of the benefits of using a backend language like PHP.
● “footer.php“: Like the header file, our footer content is separated into another file
called “footer.php”. For now, we only writing basic code. And loading our vital
javascript file for Bootstrap 5.
● “social_link.php“: this file is purely for enabling those awesome-looking social icons
that you see on all modern websites.
Now let’s see the UI/UX code of our PNG to JPG converter.
“header.php“

</div>

<br>
Now our main file that first in our browser. Do note down that all our file link back to our main
file.
“index.php“
<?php
4. //import the converter class
require('image_converter.php');
if ($_FILES) {
$obj = new Image_converter();
//call upload function and send the $_FILES, target folder and input name
$upload = $obj->upload_image($_FILES, 'uploads', 'fileToUpload');
if ($upload) {
$imageName = urlencode($upload[0]);
$imageType = urlencode($upload[1]);
if ($imageType == 'jpeg') {
$imageType = 'jpg';
}
header('Location: convert.php?imageName=' . $imageName . '&imageType=' . $imageType);
}
}
?>
<?php include("includes/header.php"); ?>
<div class="container pb-4">
<div class="row">
<div class="col col-lg-12 col-md-12 col-sm-12">
<h1 class="text-center h2 fw-bold">Image Converter</h1>

</form>
</div>
</div>
</div>
</div>
<?php include_once("includes/social_link.php"); ?>
</div>
<?php include("includes/footer.php"); ?>
5. Note: Here are some important points to keep in mind when to convert png to jpg or vice
versa.
● “image_converter.php“: this is an important file for our project. Hence we have
made it require. Unlike “header.php” or “social_link.php”. Why? Read this article
about the difference between require() and include function.
● In our image uploading form code, we added “enctype=”multipart/form-data“. This
is a compulsory HTML attribute if you want to upload a file in your HTML form. Read
more about the Enctype attribute in this MDN guide.
Lastly, we need to code our footer:
“footer.php“
<footer class="bg-dark mt-auto">
<div class="container-fluid">
<p class="text-light text-center py-3">@2022 Image Converter || All Right Reserved || <a
href="https://beproblemsolver.com">Designed by Be Problem Solver</a></p>
</div>
</footer>
</body>
<!-- JavaScript Bundle with Popper -->
<script

<script src="https://kit.fontawesome.com/0a82b36f45.js" crossorigin="anonymous"></script>
<script src="js/main.js"></script>
</html>
As you saw, we relied on Bootstrap 5 for major CSS changes. But still, need a tiny bit of
custom CSS to make our JPG to PNG converter shine.
“style.css“
/* Author: Pawan */
/* Custom Styles Here */
:root {
--theme_color_primary: #C197D2;
}
/* Utility */
body {
background-image: url(../img/bg.jpg);
background-image: url(../img/bg.svg);
background-size: cover;
font-size: 16px;
position: relative;
font-family: 'Quicksand', sans-serif;
}
/* Social Icons */
.fa-square-facebook {
6. color: #3b5998;
}
.fa-square-twitter {
color: #00acee;
}
.fa-square-instagram {
color: #f09433;
}
.social_icons .btn:hover {
border-color: transparent;
}
/* Navbar */
.only-top-navbar {
background-color: var(--theme_color_primary) !important;
}
/* Card */
.gradient-card {
background: linear-gradient(90deg, #C197D2 0%, #f8a8c5 100%);
}
/* Select Element */
.select-box select {
width: 60%;
margin: 0 auto;
}
.img-200 {
height: 200px;
}
We are done with the UI part. Don’t worry you can download images used in this project at
our Github Repo. Or feel free to use your images for styling.
Now let’s see what we code into other files to make our JPG to PNG image converter work.
But before that wanna learn how to use APIs in your web project or in an app? Check our
post!
The logic behind PNG to JPG Image converter
For ease of use and to separate UI from logic we have created the “image_converter.php”
file. This file is contains our PHP modules which convert jpg to png or convert png to jpg.
<?php
class Image_converter{
function convert_image($convert_type, $target_dir, $image_name, $image_quality=100){
$target_dir = "$target_dir/";
$image = $target_dir.$image_name;
$img_name = $this->remove_extension_from_image($image);
7. if($convert_type == 'png'){
$binary = imagecreatefromstring(file_get_contents($image));
$image_quality = floor(10 - ($image_quality / 10));
ImagePNG($binary, $target_dir.$img_name.'.'.$convert_type, $image_quality);
return $img_name.'.'.$convert_type;
}
if($convert_type == 'jpg'){
$binary = imagecreatefromstring(file_get_contents($image));
imageJpeg($binary, $target_dir.$img_name.'.'.$convert_type, $image_quality);
return $img_name.'.'.$convert_type;
}
if($convert_type == 'gif'){
$binary = imagecreatefromstring(file_get_contents($image));
imageGif($binary, $target_dir.$img_name.'.'.$convert_type, $image_quality);
return $img_name.'.'.$convert_type;
}
return false;
}
public function upload_image($files, $target_dir, $input_name){
$target_dir = "$target_dir/";
$base_name = basename($files[$input_name]["name"]);
$imageFileType = $this->get_image_type($base_name);
$new_name = $this->get_dynamic_name($base_name, $imageFileType);
$target_file = $target_dir . $new_name;
$validate = $this->validate_image($files[$input_name]["tmp_name"]);
if(!$validate){
echo "Doesn't seem like an image file :(";
return false;
}
$file_size = $this->check_file_size($files[$input_name]["size"], 1000000);
if(!$file_size){
echo "You cannot upload more than 1MB file";
return false;
}
$file_type = $this->check_only_allowed_image_types($imageFileType);
if(!$file_type){
echo "You cannot upload other than JPG, JPEG, GIF and PNG";
return false;
}
if (move_uploaded_file($files[$input_name]["tmp_name"], $target_file)) {
return array($new_name, $imageFileType);
} else {
echo "Sorry, there was an error uploading your file.";
}
}
protected function get_image_type($target_file){
$imageFileType = pathinfo($target_file,PATHINFO_EXTENSION);
return $imageFileType;
8. }
protected function validate_image($file){
$check = getimagesize($file);
if($check !== false) {
return true;
}
return false;
}
protected function check_file_size($file, $size_limit){
if ($file > $size_limit) {
return false;
}
return true;
}
protected function check_only_allowed_image_types($imagetype){
if($imagetype != "jpg" && $imagetype != "png" && $imagetype != "jpeg" && $imagetype !=
"gif" ) {
return false;
}
return true;
}
protected function get_dynamic_name($basename, $imagetype){
$only_name = basename($basename, '.'.$imagetype);
$combine_time = $only_name.'_'.time();
$new_name = $combine_time.'.'.$imagetype;
return $new_name;
}
protected function remove_extension_from_image($image){
$extension = $this->get_image_type($image);
$only_name = basename($image, '.'.$extension);
return $only_name;
}
}
?>
Convert Image Format
Now that we understood the logic let’s keep coding to the part where we convert our image
format. Or convert png to jpg and convert jpg to png. We can even convert any image format
to GIF as well.
“convert.php“
<?php
require('image_converter.php');
$imageType = '';
11. Almost to the finish line! Now we only to create a file that will allow us to download our
converted file.
“download.php“
<?php
$file_path = $_GET['filepath'];
header('Content-Type: application/octet-stream');
header("Content-Transfer-Encoding: Binary");
header("Content-disposition: attachment; filename="" . basename($file_path) . """);
readfile($file_path);
?>
Congrats! Now you completely built your own image converter that can convert png to jpg.
Or if you desire then convert jpg to png. Or maybe convert them to gifs.
And finally, you can download our JPG to PNG and PNG to JPG image converter files from
the below Github Link:
