Resolved: Having Issue on Redirecting With Session in WordPress

Question:

I am trying to create a simple login system in WordPress using core PHP but I am getting this error message

Warning: Cannot modify header information – headers already sent by (output started at /www/www/www/wp-content/themes/mytheme/header.php:20) in /www/www/www/wp-content/themes/mytheme/page-solutions.php on line 9

In the header.php template I have

<?php
session_start();
/**
 * The header.
 *
 */
?>
<!doctype html>
<html lang="en">
<head>
...

and in the page-solutions.php page

As you can see I am trying to redirect not logged users to front-page.php which I called it Home but I am getting error on header("location: home"); Can you please let me know how to fix this?

Answer:

Functions that modifies headers must be called before any output is made. In this case you’re calling get_header() functions which sends an output, and then youre trying to modify the header. Try changing the order that you execute the code, like this:

If you have better answer, please add a comment about this, thank you!
