Best way of sending a user to a new URL

Anon

I've got a form that the user fills out. When he submits the info he is sent to another page that checks the input to ensure it's in the proper format.
If the email is not in proper form(i.e. AOLLuser) how can I redirect them to the original form page?

I'm sure there is a function that will allow me to do this, but I searched the Manual and it was not pulling any relevant info.

As an extension of this question, to process input, I would have to place the conditional statements on another page. I need to do this because the server had to interpret the data and once a page has been served, the HTML that the user sees is static, correct?
I know this question is really basic, but I want to make sure I understand this.

most people use header();

header("Location: url");

You'll find it in the manual. You may not output ANYTHING before you make the call to header. That shouldn't be a problem for what you're doing.

Try using :

In this case, the global variable $PHP_SELF will have the value of the current script's name. What you are actually doing is forcing a reload of the current script.

This assumes, of course, that the error checking is done in the same php file.

The right way to do this is your code to recreate the form, preserving all of the user's input data, and pointing out the one item that needs to be changed.

There is a special place in hell for programmers who reject input but throw away all of the user's good data.
