I do something similar. However, my layout is like this:
----------
if( isset( $submit )) {
errorChecking();
if( $noErrors ) {
doDBInsert();
header( "location: blah" );
exit();
} // end if( $noErrors )
showErrors();
} // end if( isset( $submit ))
displayForm();
------
This accomplishes a few things:
* The code is easier to follow
* If there is an error in the form, the errors display and the
form re-displays. There is only one section of code that deals
with the form, not two as there would be in an IF/ELSE situation.
But then, this is just me. :)
