Submit Multiple Checkbox Value to PHP using jQuery & Ajax

In this post, I will show to you an example on how to submit multiple checkbox value to PHP using jQuery and ajax. In my previous post I posted about on how to loop the checked checkbox value in jquery. Now we will send it to the server-side so that the PHP can read it and process to MySQL database.


Sample Output

Here is the sample output of this function.

HTML, CSS, and Javascript Code

Here is the complete HTML, CSS and Javascript code:

<!DOCTYPE html>
	<meta charset="utf-8">
	<title>Loop Checkbox Value in jQuery</title>

	<style type="text/css">
		.result-wrapper {
			display: none;
	<form id="form" action="server.php">
		<label>What animals you have at home?</label>

			<input type="checkbox" name="animals[]" value="Dog"> Dog
			<input type="checkbox" name="animals[]" value="Cat"> Cat
			<input type="checkbox" name="animals[]" value="Pig"> Pig
		<button type="button" id="submit">Submit</button>


  <script type="text/javascript">
  	$(document).ready(function() {

  		$("#submit").on("click", function() {
  			var $this 		    = $(this); //submit button selector using ID
	        var $caption        = $this.html();// We store the html content of the submit button
	        var form 			= "#form"; //defined the #form ID
	        var formData        = $(form).serializeArray(); //serialize the form into array
	        var route 			= $(form).attr('action'); //get the route using attribute action

	        // Ajax config
		        type: "POST", //we are using POST method to submit the data to the server side
		        url: route, // get the route value
		        data: formData, // our serialized array data for server side
		        beforeSend: function () {//We add this before send to disable the button once we submit it so that we prevent the multiple click
		            $this.attr('disabled', true).html("Processing...");
		        success: function (response) {//once the request successfully process to the server side it will return result here
		            // do something here after successfully submitted
		        complete: function() {
		        	$this.attr('disabled', false).html($caption);
		        error: function (XMLHttpRequest, textStatus, errorThrown) {
		        	// You can put something here if there is an error from submitted request


PHP Code

Here is the PHP code to catch the submitted form via ajax. Filename: server.php. Which I call it in previous code in form attribute action="server.php".

	$request = $_REQUEST;




Now you have the complete code on how to do it. Now its your time to test it to your end.
