So, thanks to cjbj I finally found the correct answer! I needed to use edited_term instead of edit_term. Very subtle difference. edited_term fires after a term has been saved. // insert stuff into description field of taxonomy function insert_taxonomy_content( $term_id, $tt_id, $taxonomy ){ // only insert content on certain taxonomies if ( $taxonomy === ‘some_custom_taxonomy’ … Read more
If you have only one template it’s fine to do something like: echo ‘<p class=”whatever”>’ . get_the_excerpt() . ‘</p>’; However, if you have multiple templates and want to control the classes centrally, you can make a filter on get_the_excerpt as follows (but yeah, that would be in functions.php): add_filter (‘get_the_excerpt’,’wpse240352_filter_excerpt’); function wpse240352_filter_excerpt ($post_excerpt) { $post_excerpt=”<p … Read more
That is not really a question in the focus of WordPress, is also in other programming languages and in our speaking language a topic. Maybe I can clear the difference between these words with a non coding example. Callback A return of a situation to a state. Like a call with the telephone to a … Read more
Use regex to find all the urls and filter by type. $post = get_post( 504 ); $content = $post->post_content; // match all urls preg_match_all( ‘/(http:|https:)?\/\/([\w_-]+(?:(?:\.[\w_-]+)+))([\w.,@?^=%&:\/~+#-]*[\w@?^=%&\/~+#-])?/’, $content, $matches ); $count = 0; if ( ! empty( $matches ) && ! empty( $matches[ 0 ] ) ) { foreach ( $matches[ 0 ] as $url ) { … Read more
You can use var_dump() instead of print_r() – you get the type and the value of the variable and it will also work when your variable holds FALSE or NULL. print_r( false ); # doesn’t output anything var_dump( false ); # output: bool(false) print_r( NULL ); # doesn’t output anything var_dump( NULL ); # output: … Read more
add_action() and add_filter() take 4 params: string $tag, callable $function_to_add, int $priority = 10, int $accepted_args = 1. So, the function you are hooking to takes more than 1 param, then just pass the number of params it accepts as the 4th param to add_action(). In your case, add_action (‘my_action’, ‘my_function’, 10, 2) ;
As described in the Child Themes entry in the codex: TIP FOR THEME DEVELOPERS. The fact that a child theme’s functions.php is loaded first means that you can make the user functions of your theme pluggable —that is, replaceable by a child theme— by declaring them conditionally. if ( ! function_exists( ‘theme_special_nav’ ) ) { … Read more
One thing you can try is going into the page’s Edit mode, by pressing “Edit” on that page, and then checking whether that text is by any chance the actual excerpt. If you can’t see an “excerpt” section on that page you can go to the top of that page, click “Screen Options” on the … Read more
You can add to before or after the content as well in a similar fashion. I use this code: function rt_before_after($content) { $beforecontent=”This goes before the content.”; $aftercontent=”And this will come after.”; $fullcontent = $beforecontent . $content . $aftercontent; return $fullcontent; } add_filter(‘the_content’, ‘rt_before_after’); You could use it similarly with the_title,. The reko_hook() you have … Read more
