Hi, Trent, this is the correct callback function to use after my test

$.post(“vars.php”, { userid: uid }, function(data) {
if(data == ‘true’) {alert(data);}
else{ $.prompt(‘An Error Occured while removing this user’); }
});

Sample vars.php

Hope this help someone. :)

Hey Martin,

the $.post will call the php file:
$.post(‘removeuser.php’,{userid:uid}, callback:function(data){

then in the call back the “data” function parameter will have the output of the php file, so within your php file if the action is successful you can do echo “true”; or echo “false”; if the action is not successful. For this script it is only looking for a one word response. You could however create xml, but then you will need to parse it on the jquery side. I was shooting for the simplest possible example.

Trent, can I ask you how can I get the php file to send back data to the original script?

// if($.trim(data) == ‘true’) {

It could be a difference in versions of jQuery, that example runs on 1.2.1. It’s getting about time for me to update the examples again.

Hi Trent
I am getting an error exactly on that line and on the click of the “delete” nothing happens at all apart from receiving an error.

I removed callback: leaving just function(data) and it works great.
I am using jquery 1.2.3

Hey Martin,

I have that commented out since I didn’t write the php side to the script. If you’re trying to get the php side to work then be sure you’re printing out “true” or “false” from the php. Also you might want to add $.trim() to that if statement:

$.post(‘removeuser.php’,{userid:uid}, callback:function(data){
if($.trim(data) == ‘true’){…

something wrong here I suppose…
$.post(‘removeuser.php’,{userid:uid}, callback:function(data){

Hey Bryan,

It looks like in your editPrompt() your id for editname is wrong, one says editproduct(prompt text), the other says editname(in the submit validation). Hope that helps! Looks good!

Hey there. Before I show this keep in mind I’m a total newbie at Javascript. But I copied your code and modified it slightly, and am having a TON of trouble getting the edit function to do anything.

Any help you could give on why the submission on edit is not going through would be GREATLY appreciated. Just click on the first product name.

Thank you SOOOOO much.
