Header() not working, and sessions not starting
ryanmetzler3 replied to ryanmetzler3's topic in PHP Coding Help
I have found that the error is always at the line where the first php tag occurs. Right now it is reading an error at line 12 which is the first php tag in the code. If I delete that section (because it does not contribute to the functionality of the code) , the errror reads line 19 which is the next php tag. If I delete that, the error jumps to the next php tag. It doesnt like the first php tag for some reason. -

Here is all the code. I put line 12 in red so you can see it easier.

I have a script where a user can register and then login to my site. It all works fine on WAMP. When I put it on a live server I am having issues. I am getting this error when you try to login. Warning: Cannot modify header information - headers already sent by (output started at /home/wetdogno/public_html/login_scripts/login.php:12) in /home/wetdogno/public_html/login_scripts/login.phpon line 75 I know sessions are not starting becuase normally when you register, it automatically logs you into the account you just created, but its not doing that. It creates the user, because their information gets injected into my DB. Their session just isn't starting. Also the header() function is not working. Here is the code that the error message describes. I really don't think its a white space issue like many of the blogs that I have read indicated. f ($password == $dbpass) { if ($dbactive == 1) { $_SESSION['userid'] = $dbid; $_SESSION['username'] = $dbuser; header('Location:/login_scripts/member.php'); }

Hello everyone, I just wrote a significiant amount of code using mysql commands. I am now finding out that mysqli is the better option. Will mysql commands not work in the future? Do you have to switch to mysqli to avoid any potential issues?
