How to Send a JavaScript Array to PHP Using jQuery AJAX?

Posting JavaScript Array to PHP Using jQuery AJAX

To pass a JavaScript array to PHP using jQuery's $.ajax method, follow these steps:

Problem:

In your code, you're assigning the JavaScript array activities to the data option directly as a string:

data: "activitiesArray="+activities,

This method is incorrect as it attempts to send the array as a single string value rather than an array of individual elements.

Solution:

To properly send a JavaScript array to PHP through jQuery AJAX, use the data option as an object:

data: { activitiesArray: activities },

By using an object, each element of the activities array will be converted into a key-value pair, where the key is the element's name and the value is the element's value.

PHP Access:

In PHP, you can access the array using the $_REQUEST superglobal:

<?php
$myArray = $_REQUEST['activitiesArray'];
?>

This will give you an array containing the elements of the JavaScript activities array.
