Question

I am trying to edit a file on my server when a user clicks a button on my web page. I generate a table of buttons using php. STRING1, STRING2 and BOOL are variables I pass to my function. The editPlist() function I made is called and the test alert() shows. The problem is that the php file is to run. I am not getting any errors either. I can’t seem to figure out what is wrong.

Sample HTML button:

<a href="#" onclick="editPlist('STRING1', 'STRING2', 'BOOL')" class="buttong">1 : Round 1</a>

The button click runs this script: (the PHP in the url line generates the address of the file I want to run.)

<script type='text/javascript'>
function editPlist(stage, dance, oldValue)
{
    alert('test ' + stage + dance + oldValue);
    $.ajax({
        type: "POST",
        url: <?php echo '"'.dirname(curPageURL()).'/PlistEditorFunction.php"' ?>,
        data: {"var1" : stage , "var2" : dance , "var3" : oldValue},
        success: function(msg){
            alert( "Data Saved: " + msg ); //Anything you want
        }
    });
}

In the external php file PlistEditorFunction.php, I try to log a fake error and load the variables, but the error never shows. this is the beginning of the php file:

$msg = 'test error message';
error_log('['.date("F j, Y, g:i a e O").']'.$msg."<br /> \n", 3,  $phperrorPath);
if (isset($_POST['data']) and trim($_POST['data']) != '' ) {
    $stage = trim($_POST['var1']);
    $dance = trim($_POST['var2'])
    $oldValue = trim($_POST['var3']);
}

I know that the php script will only be run if the domain name matches file where the ajax is being run from. The two files are next to each other so I know that this isn’t the problem.

What can I do to fix this?

After mwotton’s comment, I figured out that ajax was undefined. jQuery was imported, so that wan’t the problem. I found the answer was I had to change $.ajax to jquery.ajax.

Some hosts don’t use “$” to denote jQuery. My web host uses “jquery” instead.
