Question

I’m currently AJAX’ing a login form.

var data = $(this).serialize();

This is the data I’m sending, I get this with PHP using Codeigniter like so:

$ajax = $this->input->post('data');

This returns username=john&password=doe as you’d expect.

How do I turn that into an array? I’ve tried doing unserialize() and I get null.

I believe you can use PHP’s parse_str() function: http://php.net/manual/en/function.parse-str.php

<?php
$str = "first=value&arr[]=foo+bar&arr[]=baz";
parse_str($str);
echo $first;  // value
echo $arr[0]; // foo bar
echo $arr[1]; // baz

parse_str($str, $output);
echo $output['first'];  // value
echo $output['arr'][0]; // foo bar
echo $output['arr'][1]; // baz

?>

Using your code it would be:

parse_str($this->input->post('data'), $ajax);
echo $ajax['username'] . "/" . $ajax['password'];
