So, I don't think one can write a small simple script that > can demonstrate this. I'm sure I must be misunderstanding something here. The following is a script which will show both GET and POST being received by the script, and with the same variable names but different values: =-=-=-=-=-=-=-=-=- <?php print "GET:<br/>\n"; print_r($_GET); print "<br/>\n"; print "POST:<br/>\n"; print_r($_POST); ?> <form method="post"> <input type="text" name="alfa"/> <input type="submit" name="submit" value="submit"/> </form> =-=-=-=-=-=-=-=-=-= Call this script via test.php?alfa=1234 Call it the first time this way and leave that in the location bar of your browser. Now fill in the value in the blank with the value 4567. Press the "submit" button. You will see that $_POST['alfa'] returns 4567, while $_GET['alfa'] returns 1234. It sounds like you're saying this isn't possible, yet it is. So what am I missing? Is there an error in my code? Paul -- Paul M.
