Question

Once upon a time, I was using PHP to display all my data. Now I want to use AJAX.

Where I used to get my data in PHP:

<?php 
    $array = $this->disparray;

    foreach($array as $key => $value){
        $mlsnum = $value['1'];
        echo "<div>" . $mlsnum . "</div>";
    }
?>

Where $this->disparry was some function in joomla that put data into an array. The structure of which looked like

array (

    0 => array (
        0 => data1,
        1 => data2,
    );,

    1 => array (
        0 => data1,
        1 => data2,
    );,

);

now I have an AJAX function that works (or at least returns an alert.

var results = $('#hidden').serialize();

var url = 'index.php?option=com_mls&view=list&format=raw&' + results;

$.ajax({
    url: url,
    success: function(data){
        $('#test').html(data);
        alert(data);
    },
    error: function(){
        alert('There was an error loading your request.  <br />Please try again later.');
    }
});

Nothing is written to #test and nothing is displayed in the alert(even though the alert happens). Why for? I should be getting a whole lot of array data, except I don’t even get a lump of coal.

Make sure you’re encoding your php array before echoing it out so jQuery can parse it.
