I have a jQuery-function that passes a list of objects to my server via AJAX:

var pList = $(".post:not(#postF)").map(function() {
  return this.id;
});
    $.ajax({
        type: "POST",
        url: "refresh",
        data: "pList="+pList,
...

on PHP-side, I need to check if a certain needle is in that array, I tried the following:

$pList = $_POST['pList'];

if(in_array('p82', $pList)){
    error_log('as');
}

which does not work, although "p82" is in the array. Maybe the jQuery object is not a real array or not passed to PHP as an array? Thanks for any help.

you cannot send array to php via ajax.. you will have to make it as json and send the json which you can jeson_decode on php side.. –  Dinesh May 1 '13 at 9:32
    
You can simply add var_dump($_POST['pList']); to your PHP script and then have a look what it outputs via developers.google.com/chrome-developer-tools/docs/network or Firebug. And yes, you need to serialize your list. –  MartyIX May 1 '13 at 9:33
    
so "data: "pList="+JSON.stringify(pList)" and decoding it server-side should make it better? –  Raphael Jeger May 1 '13 at 9:39

Add .get() to the end of your map function: 

var pList = $(".post:not(#postF)").map(function() {
  return this.id;
}).get();

Then stringify the pList object:

data: 'pList=' + JSON.stringify(pList)

Decode the json server-side:

json_decode($_POST['pList']);
