you are outputting empty chars.

 

if(empty($user) && empty($pass)){
	exit;
	}else{
		} ?>
            <?php 
		$sql 

 

 

should be

 

if(empty($user) && empty($pass)){
	exit;
	}else{
		} 
		$sql 

 

why open and close the tags??

 

any characters before a header statement will throw this error.

Hi

the open and close tags was just trying to get rid of error  what do you mean characters before a header ? can you show me an example of the best way round please

 

Many thanks

Get rid of the empty else{} and remove the unnecessary close/open php tags that follow it and see what you get. If that doesn't take care of it, copy/paste the error message here.

if what you have posted is  your entire header then removing the <?php ?> tags will fix it.

If you have other content in between the tags then it will not work.

 

You cannot output any character whatsoever before sending a header().

 

so if you do this:

 

echo ' ';
header (foo);

 

it will fail.

 

if you do this:

 

 <?php header(foo); ?>

 

it will fail. (notice the space before <)

This is the error it says

 

Warning: Cannot modify header information - headers already sent by (output started at /home/content/80/5047580/html/webdazsign/admin/script/loginS.php:13) in /home/content/80/5047580/html/webdazsign/admin/script/loginS.php on line 21
