just out off curiousity...

is ti possible with a while loop..?

[kumarsena]

if (!isset($_POST['name']) ¦¦ empty($_POST['name']) ¦¦!isset($_POST['email']) ¦¦ empty($_POST['email']) ¦¦!isset($_POST['messege']) ¦¦ empty($_POST['messege']) )
{
echo 'Please fill in all fields';
exit();
}

else
{
//do something
}

was wondering if the above code, which chceks for set and empty fields, can be done with a while loop. or any opther way for that matter? above code works fine, but just like to know my options...

Well there are always several ways of doing the same thing, but in this particular case, I think an if statement is just fine, and I can't think of a way a while loop would help.

Agree with Cook here if it's just this few - but if it's more (and later it will be, if not this script, than another script):

$errorflag = 0; 
$checkarray = array('name', 'email', 'message'); 
foreach($checkarray as $v){ 
if(empty($_POST[$v])) $errorflag = 1; 
} 
if($errorflag) { 
echo 'Please fill in all fields'; 
} else { 
/* do something else */ 
}

note: checking to see if $x is set and if it's empty is redundant. For this you can just check if it's empty.

To make this

(!isset($_POST['name']) ¦¦ empty($_POST['name']) ¦¦!isset($_POST['email']) ¦¦ empty($_POST['email']) ¦¦!isset($_POST['messege']) ¦¦ empty($_POST['messege']) )

a while look , first you need to make them variable second you need to use your brain like a mathematicians.

They Work hard
get the solution
calculate the complexity
(never think there is an alternative , never think is it needed , just prove thats possible)

AjiNIMC mathematician by mistake
