simple question...

Can someone please help me with this simple question?

How to limit the size of referrer value to maximum 8 characters?

$REFERRER = $_POST['REFERRER'];
	if ($REFERRER==$name || $REFERRER==$_acct || $REFERRER=="") {
		$REFERRER = $_def_ref;
	}

PHP:

Thank you!

 

if (strlen($REFERRER) > 8)
 {
 echo "You have entered a referrer name longer than 8 characters";
 }
else
 {
 //rest of code.
 }

PHP:

 

If your looking for a way to limit the length, rather than not allow, like papa_faces's code try:

<?php
echo substr('$REFERRER', 0, 8);
?>

Code (markup):

That will only output the first 8 characters.

 

what i really want is: if referrer is longer than 8 chars then exit script

something like that...
if ($referrer==0) exit;

just instead of 0 i want my 8 chars rule

thank you everyone so far


is this correct?

if (strlen($REFERRER) > 8) exit;

 

Use

if (strlen($REFERRER) > 8)
 {
 exit;
 } else {
blah blah blah
 }

Code (markup):

 

can't i write this without the else code? only like this:

if (strlen($REFERRER) > 8) exit;

then continue with normal code...


OR USE THIS:

if ($REFERRER==$name || $REFERRER==$_acct || $REFERRER=="" || strlen($REFERRER) < 8)

 

Yes you can use just something like this:

$REFERRER = $_POST['REFERRER'];
if (strlen($REFERRER) > "8") { exit; } 
// continue script here.

Code (markup):

 

thank you! thread closed now.
