RE: [PHP] PHP_SELF

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. -----Original Message----- From: Gerard Samuel [mailto:trini0@optonline.net] Sent: Monday, July 30, 2001 3:30 PM To: PHP 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 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net For additional commands, e-mail: php-general-help@lists.php.net To contact the list administrators, e-mail: php-list-admin@lists.php.net
