Hey guys I am having the most hard time trying to figure this out.

I think I understand lightboxes and how they work. I used on in a play server and it worked fine; until I used it in an if else statement in php to test out form validation. If the user fills the form inproperly than this lightbox of a fail image should popup, but it doesn't. I do hope that someone in this wonderful sight could help me

$EmailAddres = $_POST[Email];
$FirstName = $_POST[FName];
$LastName = $_POST[LName];
$PhoneNumber = $_POST[Phone];
$AltPhoneNumber = $_POST[AltPhone];


//This is the testing and the validation testing
$flag="OK";
$msg="";
$todo="test";



if(!ereg("^[-A-Za-z]*$",$FirstName)){
     echo "Invalid first Name";
     $flag="NOTOK";
}

if(!ereg("^[-A-Za-z]*$",$LastName)){
   echo "Invalid Last Name";
   $flag="NOTOK";
}


if(!ereg("^[-A-Za-z0-9_]+[-A-Za-z0-9_.]*[@]{1}[-A-Za-z0-9_]+[-A-Za-z0-9_.]*[.]{1}[A-Za-    z]{2,5}$",$_POST[Email])){
     echo "Invalid Email Address";
     $flag="NOTOK";
}

/*This is to validate the phone number input */ 
    if(!ereg("[0-9]{10,11}", $PhoneNumber)){
         echo "Invalid phone number"; 
         $flag="NOTOK";
} 


if($flag == "NOTOK"){
    echo '<p><a href="images/fail.png" rel="lightbox" class="lightbox_trigger"&g开发者_JS百科t;</a></p>';
   // echo "something is definitely wrong here";  
}
?>
</html>

It's not enough to just print out the link reference with PHP. You need to set the javascript in motion.

Here is a short blog entry from someone who solved your exact same problem. It's older, but it works.
