why not to use the_title filter? add_filter(‘the_title’, ‘the_title_filter’); function the_title_filter($title){ $post = get_post(get_the_id()); //enter code here return $title; } as for shortcode – its imposible. in logical way – imposible.
It won’t work the way you are doing it, but you are close. The reason you have to use a global is that you aren’t setting your $meta variable with the information returned from the filter. This: do_action(‘alter_loop’,$meta); Should be this: $meta = apply_filters(‘alter_loop’,$meta); Note: “Actions” do not return values. “Actions” do things. “Filters” accept … Read more
Use both hooks, and call did_action to find out if the template hook fired or not. https://developer.wordpress.org/reference/functions/did_action/ did_action will return the number of times a hook/action has fired. With this you can return early in the footer action
As @cjbj noted in a comment, this is probably a timing issue. This means that instead of directly adding the code to functions.php you need to wrap it inside a callback function and attach it to a later firing action. WordPress, themes and plugins too, loads and does things in certain order. Thus some code … Read more
Yes the apply_filters() hook is bit confusing at first when you encounter it. I’ll try my best to explain this: first you need to know that filter hooks allow you to change data before displaying or storing data. Lets take an example function list_array(){ $arr_name = [‘val1’, ‘val2’, ‘val3’]; return $arr_name; } as you can … Read more
One way would be to use preg_match and remove classes that matches given patterns, but… Since we know $post_id, we can use your code with a tiny modification: function lsmwp_remove_postclasses($classes, $class, $post_id) { $classes = array_diff( $classes, array( ‘hentry’, ‘post-‘ . $post_id, ‘type-‘ . get_post_type($post_id), ‘status-‘ . get_post_status($post_id), ) ); return $classes; } add_filter(‘post_class’, ‘lsmwp_remove_postclasses’, … Read more
If I understand you correctly you’re not looking for the wp_search_stopwords filter type of solution. So here’s a modification of the great answer by @kaiser that you referred to: /** * Exclude array of words from all search queries in the front-end * * Modification of http://wordpress.stackexchange.com/a/41100/26350 by @kaiser */ add_filter( ‘posts_search’, function( $search, $q … Read more
Assuming you mean the default calendar widget, you really have two choices: Wildly complicated regex Or make your own widget. I would opt for #2, the meat of which is actually the get_calendar function. Clone that function and alter the dates as you need to. This is assuming that there is no proper localized version … Read more
It is not possible to do it exactly as you ask as once you define() a constant in php you can not redefine/override the value. But what you are trying to do is not necessary, this constant is defined as part of the installation of a localized wordress, therefor it is already there, and set … Read more
There are two ways to solve this. The first one is what you are trying, but you have to print out the value you get. Like this: print get_post_meta(); I don’t recommend this for two reasons: You should keep your templates as simple as possible. Otherwise they become cluttered with fragments of business code which … Read more
