Working with a Javascript object in PHP sent over ajax

Question

The following code sends (I hope so) a Javascript object to a php file through Jquery's ajax call.

var emails = {};
emails.name = email;
.
.
$('button.gmail').click(function() { 
$.ajax({ url: path,
 data: emails,
 type: 'post',
 success: function(status) { 
 alert(status); 
 }
 });
});

how can I examine this object in PHP and retrieve its keys/values?

• Chad: This will encode the object into a application/x-www-form-urlencoded string, which will be available via $_POST in PHP.
• adeneo: Just do print_r($_POST) in your PHP file, and the alert will show whatever you received in the PHP file, which should be exactly the same as whatever you sent ?

Answer 1

This will encode the object into a application/x-www-form-urlencoded string, which will be available via $_POST in PHP.

So if your data object is something like:

var data = {
 foo: 'bar',
 baz: 10
};

Then in PHP you will have:

$_POST['foo'] //is "bar"
$_POST['baz'] //is 10

Answer 2

<?php
 $foo = $_POST['foo']; //this will assign whatever 'foo' was assigned in the javascript POST request
