Question

I have an image slider and every time the next image is loaded I need to save a record to the database. I am trying to accomplish this using jQuery and AJAX.

I write the info I need to a hidden field called data so I can post it to my PHP page.

    function ajaxSave(){
        $("#data").val($("#image").attr("src")+","+ratings[iCount]);
        //alert($("#data").val());//Testing
        $.ajax({
            type: "POST",
            url: "ajax/ajaxSave.php",
            data: $("#data").val(),

            success: function(data){
                alert(data);//only for testing purposes
            }
        });
    }

I call my ajaxSave() function every time the next button is pressed. I get my alert that was successful but my question is: What is the $_POST[”] array cell for this?

I need to manipulate the data in the php page (see below), but I only get an alert that says “array ( )”.

<?php
    print_r($_POST);
?>

I’m very new to AJAX so any help would be greatly appreciated! Thanks.

Answer 1

The data for the Ajax should be sent as a map..

So instead of

data: $("#data").val(),

Try

data: { 'param' : $("#data").val() },
