RE: [PHP] form validation

I think the best way to do this is to do the validation within the same form page (domain.php). If you use header(); to redirect the user back the page, you will loose all values of any of the other fields. this will be frustating for the user. Here is an easy way to do it, quick and dirty, not the most efficient but it should get you off to a good start. Try something like this: <? if($action == "validate"): if(!$first_name || !$last_name || !$address1 || !$address2 || !$phone || !$email || !$paymentmethod){ $error_msg = "You did not fill in all Required Fields"; } endif; ?> <? if(!$action || isset($error_msg)): ?> <? if(isset($error_msg)): ?> <H2><FONT COLOR="red"><? echo "$error_msg"; ?></FONT><H2> <? endif; ?> <FORM ACTION="<? echo "$PHP_SELF?action=validate"; ?>" METHOD="post"> <INPUT TYPE="text" NAME="$first_name" VALUE="<? echo "$first_name"; ?>"> <? if(isset($error_msg) && !$first_name): ?><IMG SRC="error_img.gif" BORDER="0"><? endif; ?> <INPUT TYPE="text" NAME="$last_name" VALUE="<? echo "$last_name"; ?>"> <? if(isset($error_msg) && !$last_name): ?><IMG SRC="error_img.gif" BORDER="0"><? endif; ?> ... ... <INPUT TYPE="submit" VALUE="Submit"> </FORM> <? endif; ?> <? if(isset($action) && !$error_msg):?> <H2>Thank you for Submitting this Form. Below is your Info:</H2> First Name: <? echo "$first_name"; ?><BR> Last Name: <? echo "$last_name"; ?><BR> ... ... <? endif; ?> -----Original Message----- From: "george" <@toye.php.net gmclachlan @btinternet.com [mailto:nospam@netraiser.com] Sent: Friday, October 20, 2000 7:09 AM To: php-general@lists.php.net Subject: [PHP] form validation I have a form which when you type a domain name into it ,it searches a database to see if that name is available,if it is it goes to a another form which they must fill out with their name and address etc,which is then mailed to me,i want to use php to validate the form but i 'm not too sure how to.,basically i want to check if they have filled in the requried fields and if not send them back to the page and place a graphic beside each of the fields not correctly filled in ,on my confirmation page which lists all the details they have supplied i have if (($first_name == "") && ($last_name == "") && ($address1 == "") && ($address2 == "") && ($town == "") && ($phone == "") && ($email == "") && ($paymentmethod == "")) { header("Location: http://wisemonkeydesign.co.uk/domain.php"); exit; but it doesnt work, I hope someone can help me solve these 2 problems Thanks in advance George -- 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
