#1 Including a template file in the plugin, with the ability to change it in the theme

Suppose we create a plugin and in it we need to specify the template file that will be used in the theme. Consequently, the template file will be different for different themes and we need to leave the possibility to change the template file in the theme. To do this, we will connect the plugin file, only if it is not defined in the theme:

// return file path if the child or parent theme has such a file
$overridden_template = locate_template( 'some-template.php' );

if ( $overridden_template ) {

	load_template( $overridden_template );
}
// file is not found in the theme or child-theme
else {
	// load the file from the 'templates' directory of the plugin
	load_template( __DIR__ . '/templates/some-template.php' );
}

#2 Send variable (data) to the template file

You can send additional variable with load_template() by passing the third parameter.

$args = [
	'text' => 'Hello Template File',
];

$template = locate_template( 'template.php' );

if( $template ){

	load_template( $template, true, $args );
}

In template.php file you can access this variable like this:

echo $args['text']; //> "Hello Template File"
