Subject: [PHP] PHP_SELF
Im trying to introduce some logic into a form.I am unsing $PHP_SELF as
the target.
<form action=\"$PHP_SELF\" method=\"POST\" type=\"multipart/form-data\">
I have a text area that the user inputs their age. What I want is that
if the field is blank, to stop the script and send the user back to fill
in their age. My problem now is that if I go to the blank application
form, The script interprets the form as being blank and spits out the
error. Ideal scenario, a blank form is presented to the user, and when
the form is submitted, do the logic check and act accordingly. Is it
possible using $PHP_SELF as the target, or do I have to use 2 files: a
form 'front end' with the php logic in the 'backend'??
if ($Age = " ") {
echo "Please go back and enter your age."; } exit();
Thanks
Gerard
