I personally think it is best to display a form error on the form itself,
rather than given them a blank page that shows an error, then have them
click a button or link to go back to the form. Here is somewhat a quick and
dirty example of how I go about forms and error checking. For this example I
am only checking for a required field, you can elaborate on this and check
to see if input for age is numerical, or whatever other type of
error-checking you may need to do:
<?
If($HTTP_POST_VARS){
// check required fields
if(!age ||
ame){
$formerror = "You did not fill in all required fields";
}
...
// if form passed all error checks continue processing
if(!$formerror){
// continue processessing...
....
}
}
?>
<? if(!$HTTP_POST_VARS || $formerror): ?>
<FORM ACTION="<? echo "$PHP_SELF"; ?>" METHOD="post">
<INPUT TYPE="text" NAME="name" VALUE="<? echo "$name"; ?>">
<INPUT TYPE="text" NAME="age" VALUE="<? echo "$age"; ?>">
<INPUT TYPE="submit" VALUE="Submit Form">
</FORM>
<? endif; ?>
Hope this helps.

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
