wordpress prevent error reporting

Question

i'm making a custom theme and noticed one thing. when i try to go directly to my theme index.php file through url (or anypage) for example:

localhost/wordpress/wp-content/themes/my-theme/index.php

this error will appear.

Fatal error: Call to undefined function get_header() in ... on line...

i've tried to download and activate other themes but the result is the same. how can i prevent this from happening?

i've tried adding the following lines to the wp-config.php

error_reporting(0);
@ini_set('display_errors', 0);

but with no results. i've also tested it "live" but with no results.

thank's in advance.

Answer 1

Correct me if I'm wrong but that error occurs when someone tries to directly access the theme's index.php. For example when a bot tries to access it.

You should never access it directly like this:

<?php get_header(); ?>

But rather try it like this:

<?php
  if (function_exists('get_header')) {
    get_header();
  } else {
    // Here goes whatever you want to do when the file is accessed directly.
  }
?>
