If that first blank line is actually in your source file, that is the culprit. There can be NO OUTPUT before setting a cookie or session (which also sets a cookie.)

When I type setcookie function at the first line I see header error!

Can you modify this code?

You have welcome seller/invalid seller output before setting a cookie. You were already told that there could not be any output before setting the cookie.

Sorry, scratch that, you're echoing after the setcookie, so the error must be before that. Seems that you have some whitespace before the php tag. Get rid of this.

I have an error again when I use setcookie function in the first line !!

<?php
setcookie('status','seller',time()+1600);
        if($_POST)
        {
 
            $con=mysql_connect('localhost','root','136');
            mysql_select_db('phpshop',$con);
            if($_POST['group']=='seller'){
.....

Do you have white space before the <?php tag

Whitespace inside the php tag doesn't matter

Thanks a lot!!!!

I had a white space before the <?php tag.
When I removed that , code work correctly!

Ok. So we can setcookie or session in UTF8 files!


Thanks again!
