Re: Redirect then error message to user

[Brent Baisley <brent@xxxxxxxxxxxx>]

You can pass the error in the redirect URL:
header("Location: http://www.xxxxxx.com/page1.php?errmsg=You missed 
some stuff")

On your main page you just check if there is an errmsg to be displayed:
if(isset($_GET['errmsg'])) {
	echo $_GET['errmsg'];
}

That a simplified version obviously. But that's the concept.

I design all my pages so that "one" file handles display, edit, 
validation and save. Then I don't have to worry about going back and 
forth between pages, doing redirects or retaining data through session 
variables. Most important, the user doesn't lose what they already 
entered just because they missed a field.
