Filters for internal functions

Is it possible to add apply_filters to internal functions like get_author() and etc.? This way we can do small modifications without copying the template files to child theme.

For example (Newspaper/includes/wp_booster/td_module_single_base.php:L65):

	//$show_stars_on_review - not used
	function get_author() {
		$buffy = '';
		if (td_util::get_option('tds_p_show_author_name') != 'hide') {
			$buffy .= '<div class="td-post-author-name"><div class="td-author-by">' . __td('By', TD_THEME_NAME) . '</div> ';
			$buffy .= '<a>post->post_author) . '">' . get_the_author_meta('display_name', $this->post->post_author) . '</a>' ;

			if (td_util::get_option('tds_p_show_author_name') != 'hide' and td_util::get_option('tds_p_show_date') != 'hide') {
				$buffy .= '<div class="td-author-line"> - </div> ';
			}
			$buffy .= '</div>';
		}
		return apply_filters( 'td_filters_get_author', $buffy );
	}

Hello Bogdan,

I know that I can modify original theme files but I don’t want to. 🙂 What I’m asking is you doing this, not me. So the theme gets more functionality and I don’t have to track some modifications which each theme update. It’s not something special to me, it may be useful for all Newspaper users.

I’ll try to give more details. 🙂 English is not my native language so bear with me here.

I’m a theme/plugin developer myself. I do lots of WordPress jobs for my customers. I understand child theme concept very well. No problems there, I assure you.

What I’m suggesting is, “you”, as tagDiv, could you please add filters to your internal functions? I’ll try to explain with an example.

There are 14 different (13 + default) single post styles in Newspaper theme. All of them have this line for author box;

<?php echo $td_mod_single->get_author_box();?>

This is great, so if I want to change author box, I can copy td_module_single_base.php from /includes/wp_booster/ to my child theme with the same folder structure and do necessary modifications. And voila, all of the author boxes are updated. But (there is a huge but here) now I have to inspect every changelog that if td_module_single_base.php file changed or not during version bumps. And I had to copy a whole file despite I want to change only one function.

Here comes my solution; Filters

If tagDiv could apply filters just before returning that cuddly $buffy, developers can add a hook to that filter and without copying whole td_module_single_base.php file, they can change the output of get_author_box() function.

I hope this time I explained my self much better. 🙂 Thanks for your responses.
