url parameter help

[pjheliking]

Silly question but gonna pop it off anyway. I am kinda new to php and i am working on using url parameters...

 

What i want to happen is for example url returns http://www.yourdomain.com/index.php?error=username

 

what i want to happen is the error=username activates text to appear for instance above the username box saying something like "Sorry the requested username is already in use"

 

Is it possible or is there other ways of doing this

 

any help greatly appreciated

 

thanks in advance

I wouldn't do it like that.  I'd personally handle the form on the same page as the form itself so you can directly output the errors.

im not all that up to speed with doings something like that.

[pjheliking]

<?php
if ($error="username") 
{
  echo ("<b>Sorry but that email address is already in use. Please input another again</b>");
}
?>

 

would that work?

[pjheliking]

found it

 

<?php

$var = $_GET['username'];

if (isset($var)) {
    echo "Sorry but the username you have supplied is already in use. Please try another";
}
?>

this is simple problem and GET will work but for other confidential data either use POST method or use some encryption or process the data within the same page as told by others.
