Forms : Required Fields

[The Praetorian]

I did a quick look at Forms under html, but I couldn't find it. Off the top of their head, does anyone know how to make a form field required? Or how to make the entire form required?

I'm not really sure you can try this, it is php btw, no guarantys it will work though.<?php$validate=$_POST['NAMEOFFEILD'];if ($Validate== ) {echo "Error"; }?>

Hm. I'll give that a try. How do I add multiple fields, though? Would it be like this?

$validate=$_POST['NAMEOFFEILD'];$validate=$_POST['NAME of second field'];if ($Validate== ){echo "Error";}

Or would I need to just repeat the whole array for each field?Also.. does the code need to be embedded in the form php? Or would I need a separate <?php and stuff for it?

you can put it on the same page, you must save the file as a php file (.php) and must be in a php freindly enviroment,you would have to do the same for each fieldThe form does not have to be in the <?php ?> tagsthe code is basically saying:get the form input, if the input is blank display error.if this doesn't work you will have to use javascript.

Okay, I'm still not getting it. Where exactly does the array go? Does it go above theif (isset part? And which part needs to be repeated?

<?phpif (isset($_REQUEST['email'])){$name = $_REQUEST['name'];$username = $_REQUEST['username'];$age = $_REQUEST['age'];$gender = $_REQUEST['gender'];$nation = $_REQUEST['nation'];$guild = $_REQUEST['guild'];$history = $_REQUEST['history'];$writingsample = $_REQUEST['writingsample'];$alias = $_REQUEST['alias'];$agetwo = $_REQUEST['agetwo'];$icq = $_REQUEST['icq'];$aim = $_REQUEST['aim'];$msn = $_REQUEST['msn'];$email = $_REQUEST['email'];mail( "author@tsrealms.com", "Subject: $email","~Character Information~\r\n\r\n\r\n~Name~\r\n$name\r\n\r\n~User Name~\r\n$username\r\n\r\n~Age~\r\n$age\r\n\r\n~Gender~\r\n$gender\r\n\r\n~Nationality~\r\n$nation\r\n\r\n~Guild~\r\n$guild\r\n\r\n~Brief  History~\r\n$history\r\n\r\n~Writing Sample~\r\n$writingsample\r\n\r\n\r\n~Personal Information~\r\n\r\n\r\n~Name/Alias~\r\n$alias\r\n\r\n~Age~\r\n$agetwo\r\n\r\n~ICQ~\r\n$icq\r\n\r\n~AIM~\r\n$aim\r\n\r\n~MSN~\r\n$msn", "From: $email" );echo "<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><hr class='blocktext' /><p class='blocktext'>Thank you for your application!

The PHP code goes in the form processing page, not on the page with the form itself. Or, you can make them both the same page, wihich may keep the code a little cleaner. You can define your array like this:

$formvars = array();$formvars['first'] = $_POST['first'];$formvars['second'] = $_POST['second'];$formvars['third'] = $_POST['third'];$errors = "";foreach ($formvars as $key => $val){  if ($val == "")	$errors .= "The field '{$key}' is required.";}if ($errors != ""){  echo $errors;  //show the form again}else{  //process the form}

Here's an example of how to process a form on the same page:http://w3schools.invisionzone.com/index.ph...44&hl=howto
