I am using the boilerplate for WordPress plugin : /

but I don't know if it's because of there coding this is happening.

What I am trying to do is use require and load the below code from a file.

require plugin_dir_path( __FILE__ ) . 'admin/partials/ggowl_template/ggowl_template_func.php';

if I am putting this code in the main file of the plugin it works (without require). Not sure where I am making the mistake

---

add_filter('template_include', 'ggowl_template_post_function',-20,1);

function ggowl_template_post_function($single) {
        //$ggowl_admin_options = get_option('ggowl_admin_options');
        // if( null !== get_option('ggowl_admin_options')){
        if( false !== get_option('ggowl_admin_options')){
            global $post;
            if( !is_object($post) ){
            return $single;
            }

            $ggowl_admin_options = get_option('ggowl_admin_options'); // Array of All Options
                $ggowl_admin_template_options = $ggowl_admin_options['ggowl_select_post_template_repeater'];
                foreach ($ggowl_admin_template_options as $key => $value) {
                    $posttype = $value[0];
                    // var_dump($posttype);
                    $ggowl_select_post_template_0 = (int)$value['template'][0][0];
                    if ( ($post->post_type == $posttype )&&($ggowl_select_post_template_0 != 0) ) {
                            if ( file_exists( plugin_dir_path( __FILE__ ) . 'includes/templates/ggowl-template-post.php' ) ) {
                                    return plugin_dir_path( __FILE__ ) . 'includes/templates/ggowl-template-post.php';

The filter itself probably works, but the file_exists() returns false.

So not sure if this answers the question, but one issue I see in your code is:

When you put the code in your-plugin/admin/partials/ggowl_template/ggowl_template_func.php, plugin_dir_path( __FILE__ ) from within the ggowl_template_post_function() would be your-plugin/admin/partials/ggowl_template/ — and not the main plugin file path, so I suggest you to define the main plugin file (its absolute path) in the main plugin file, like so:

<?php
/**
 * Plugin Name: My Plugin
 * Version: 1.0
 */

defined( 'ABSPATH' ) || exit;

define( 'MY_PLUGIN_PLUGIN_FILE', __FILE__ );

And from other PHP files than the main plugin file, you'd use MY_PLUGIN_PLUGIN_FILE and not __FILE__ when referencing to the main plugin file.
