raydona Posted April 7, 2012 Share Posted April 7, 2012 Hi, I have a form in file A.php. <?php <form name="A.php" action="B.php" method="post"> ...... <input type="text" name="name" id="name" /> .... <input type="text" name="email" id="email" /> .... ?> When the form is submitted php validation takes place on form B.php <?php if ( isset($_POST['submitted']) { if ($_POST[name]) { $name = $_POST[name]; } else { //what code goes here? } ...... ?> What I would like to happen in the else statement is that if name field is left blank user is automatically redirected to A.php, the name field is highlighted and a small error message that the name field was left empty appears. How can that be achieved? I would be very grateful for all help. Quote Link to comment Share on other sites More sharing options...
algidDes702 Posted April 7, 2012 Share Posted April 7, 2012 Is there a strong reason why you dont validate your form input on the same page? On A.php? for the action use "<?php echo $_SERVER["PHP_SELF"]; ?>" and include your isset validation in the top of your script. This is just one way to do it. algidDes702 Quote Link to comment Share on other sites More sharing options...
Drummin Posted April 7, 2012 Share Posted April 7, 2012 I would agree that processing/validation should be done above <html> on the same page however I would use a empty action line in the form, eg. <form action="" method="post"> I WOULD NOT USE $_SERVER["PHP_SELF"] http://www.google.com/search?q=%24_SERVER%27PHP_SELF%27+xss+vulnerability&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a Quote Link to comment Share on other sites More sharing options...

raydona Posted April 8, 2012 Author Share Posted April 8, 2012 Hi, Many thanks for the replies. Although I didn't include all the code, there is a lot of javascript in A.php to make the form appear stylish instead of the standard HTML inputs. That is why I wanted to keep the file separate from the php validation. I was wondering if I could write <form action="" method="post"> in A.php and include("A.php"); in B.php immediately below the php validation so that A.php appears immediately below the validation in B.php. But then how would I jump to input label? Quote Link to comment Share on other sites More sharing options...
Drummin Posted April 8, 2012 Share Posted April 8, 2012 That should work, although I would normally include a processing page at the top of a display page above <html>, so B.php would be included to top of A.php. Quote Link to comment Share on other sites More sharing options...
