Question

I’ve got a problem that I’m stuck on for days now…
I’m trying to use a simple ajaxPOST function to send data to a MySQL database (not WP database).

This code is located within “single-post.php” in the theme, because it must be checked before every post.

$.ajax({ url: 'library/functions/admin_checkuser.php',
     data: {action: userID},
     type: 'post',
     success: function(output) {
                  alert(output);
     }
});

I’m simply sending a variable to a “admin_checkuser.php” script which in turn calls another script that take actions on the database.

This is the code for “admin_checkuser”:

$userid = $_POST['action'];

echo $userid;//for testing
$oMySQL = new MySQL();
$query = "Select * FROM videotable WHERE uid = '$userid'";
$oMySQL->ExecuteSQL($query);
$bb = $oMySQL->iRecords;
$aa = $oMySQL->aResult;
echo $bb;

if ($bb == 0){
$query = "INSERT INTO videotable VALUES ('','$userid','true')";
$oMySQL->ExecuteSQL($query);
echo 'true';
    exit();

}else{
$sharing = mysql_result($aa,0,"share");
echo $sharing;
exit();

}

But I don’t think the calls go through to the script.
These scripts where tested outside of WordPress and did work, so it must be something in WordPress that blocking the ajax call.
BTW, I tried placing the “admin_checkuser.php” in many diffrent folders but nothing worked.

Thanks in advance.

You should check your url for your ajax call.

Maybe use the full url instead of the relative one.

It could be because of the location of your theme makes the url incorrect. I’m assuming your ajax code is in your theme folder.

There are some wordpress functions that get the theme directory.

For example if you at this page http://yourwebpage/test/ then the ajax call will go here http://yourwebpage/test/library/functions/admin_checkuser.php. This I assume would be the incorrect location.

This is why you need to add the absolute url to your script. And if it is in your theme, you can use this method get_template_directory_uri() to get the template directory.
