Php if null do code

[Grantmau5]

Sorry guys i hate this registering for an answer then leaving but i really need help. heres my code.

 

if(isset($_POST['send'])){
// Take user's name and say hello START
$rname = $_POST['rname'];
$dname = $_POST['dname'];
if($rname == null){
ob_start();
echo "JPi Encountered an error. Please try entering your real name again.";
$page = "preferences.html";
header("Refresh: 5; URL=\"" . $page . "\""); 
ob_flush();		
} 
else {
echo "Welcome, " . $rname . " to the JPi BOT. \r\n";
echo "Your current Display name is: " . $dname . ". \r\n";
// Take user's name and say hello END
	}
}

 

Basically if field equals null then give error and return to page

 

else print the welcome message.

 

For some reason it isn't working and i really can't spot my flaw.

 

Any help guys ?

 

 

Ps. I have also tried using empty, !isset, is_null...

What is happening then? empty() should work.

Thank you for the suggestion. However the header isnt the problem here.

On the previous page i have two input fields: one for the user's real name and the other for a display name.

 

Im trying to redirect them back if the real name input field is empty (null) .

Otherwise i greet them announcing them by name.

 

and no i tried the empty() function but still doesnt work. Looking at my code im sure it should work  :'(

if(empty($rname)) should work. Are you sure you're using the correct name to access the value? You're telling us something is wrong, but you're not telling us what's happening.

Never mind the code was correct. As you rightly pointed out it was an issue with the html, not the name part but i had onClick="value=' '" << i had a space inside the single quotes. Ah it's because it's midnight here, my heads not on properly. Thanks for the knock on the head i needed
