Getting arguments with AJAX

mikek12004

Is it possible to put an array of values as an argument to a js function? I want through this function and with AJAX to pass this array to a PHP array inside the PHP script which will then do the rest

You could pass a string with delimiters and split on the server-side.

So it is impossible to use an array eh?

acoder

Well, you could use an array, but it'd be passed as a string, e.g.
[1,2,3] would be passed as "1,2,3". You could serialize it on the client-side and deserialize it on the server-side.

Try something like:

Expand|Select|Wrap|Line Numbers

var myPostVars = "myArray[0]=AAA&myArray[1]=BBB";

then in PHP the $_REQUEST["myArray"] should already be a compiled array.

Expand|Select|Wrap|Line Numbers

var_dump($_REQUEST["myArray"]);

Not sure it will work, well it did in PHP3, but things have changed since then, but still worth trying. ;)

that suggestion shows a 'kind of serializing' a javascript array ... since you cannot use that easyly in both languages ... a very seamless way to handle more complex datatypes is to use JSON ... so that you might use simple eval() on JS-side and json_encode() or json_decode() in php ... that will do the serializing and deserializing for you ...

You're right, I'd prefer building an XML in JS and then parse it in PHP, think that would be the right way to do it, or JSON as you mentioned. But the question was about passing an array through an AJAX request.

JSON is more lightweight compared to XML ... so i would always prefer JSON ... and the other point is: what you have suggested is a serialized array that is passed as a string ... and no array ... to be correct :)
