Input validation and redir. with args

[Anon]

Is there a way to redirect the user BACK to a form he just filled out, and also pass along some POST method arguments? I may be going about this the wrong way, so I'll explain a bit.
I have a form that has various fields, I want to validate that these are correct, and if they are not, I want to re-display the form, with the users input, but also with some boolean data that the form page can use to display error messages. ie: http://11.22.3.44/someform.phtm?error1=1&error3=0
etc.

This is done on many sites using a variety of languages... I was curious if there was an easy way to do it in PHP

Of course you can redirect back to the form while passing all of the valid arguments; your form should echo those arguments into the input fields:

<INPUT type="text" name="foo" value="<? echo $foo?>">

But you might want to use PHP sessions instead, which will avoid cluttering up the redirect URL.
