Best way to pass JSON from Browser to PHP using Ajax.Request

Question

Hi I have a JSON object that is a 2-dimentional array and I need to pass it to PHP using Ajax.Request (only way I know how). ...Right now I manually serialized my array using a js function...and get the data in this format: s[]=1&d[]=3&[]=4 etc. ....

my question is: Is there a way to pass the JSON object more directly/efficientely?..instead of serializing it myself?

Thanks for any suggestions, Andrew

Answer 1

Pass the object as a JSON-string to PHP, and in PHP use the builtin json_decode to get a PHP-object from the string.

In Javascript, use a "stringify" function on your object to get it as a string, library available for example here: http://www.json.org/json2.js

Answer 2

You can also use Prototype's function toJSON() to convert an array into a JSON object. After passing it to server via Ajax call, simply use PHP's fucntion json_decode() to decode the object.

Answer 3

In que Javascript side (with Prototye):

var myJSON= Object.toJSON(youArray);

In que Php side:

$myjson = $_POST['myjson'];

$arrayJSON= json_decode(stripslashes($myjson), true);

Thanks so much everyone, the prototype ".toJSON()" really helps because i didn't want to use any extra libraries....I obviously just pass the info using "parameters" right?

Check http://www.openjs.com/scripts/data/ued_url_encoded_data/ to encode nested data directly correct, since Object.toQueryString() doesn't accept nested data...
