I'm trying to implement a simple server-side form validation (No
Javascript). If the user submits a form with errors, I want to
redisplay the same form with the errors highlighted. Once the form is
correct I need to submit to another page that uses the form data.

I first tried making the form submit action= field point to the same
file. When the form was correct, I tried loading the next page by using
<META http-equiv refresh>. But that doesn't post the data, so the next
page didn't have access to it.

Then I tried changing the action= field of the form to an a PHP echo. I
would echo a variable that was set to either "ThisSamePage.PHP" or
"TheNextPage.PHP", depending on whether the validation was correct. The
problem is that the user has to press Submit an extra time once the
form is correct, since the form was still displayed with the action
equal to "TheNextPage.PHP"

I have looked for some way to submit the form directly from PHP code,
but I don't know enough about PHP yet.

I think I need some way to cause a Post action from PHP code, so I can
get to the next page without redisplaying the form and having the user
click submit again.

Or is there a better way to structure this type of validation that
avoids this issue?
