$('#form').serialize(), I was able to send this over to a PHP page. Now how do I unserialize it in PHP? It was serialized in jQuery.
You shouldn't have to unserialize anything in PHP from the jquery
serialize method. If you serialize the data, it should be sent to PHP as query parameters if you are using a GET method ajax request or post vars if you are using a POST ajax request. So in PHP, you would access values like
$_GET["varname"] depending on the request type.
serialize method just takes the form elements and puts them in string form.
Provided that your server is receiving a string that looks something like this (which it should if you're using jQuery
...something like this is probably all you need:
$params = array(); parse_str($_GET, $params);
$params should then be an array modeled how you would expect. Note this works also with HTML arrays.
See the following for more information: http://www.php.net/manual/en/function.parse-str.php
Hope that's helpful. Good luck!
