You should be able to remove the existing description tag with the following code: remove_action( ‘wp_head’, ‘_wp_render_title_tag’, 1 ); Put the above snippet inside the same function you are using to conditionally add a new tag so there is always only a single description tag at a time.
It took me a while of tinkering with the hooks, but in the end, I fixed it by loading the post earlier. Instead of loop_start: $this->loader->add_action(‘loop_start’, $plugin_public, ‘mp_display_post’); I used get_header: $this->loader->add_action(‘get_header’, $plugin_public, ‘mp_display_post’); This worked properly because now the post information is loaded before wp_head gets called, and therefore I can use the loaded … Read more
The problem is that about.php is not a recognized file by WordPress and won’t load any of the actual WordPress functions. <?php wp_header(); ?> in your themes header.php file actually loads most the WordPress functionality that you’re used to using. Since you’re not calling either get_header() OR wp_header() in your about.php file you don’t actually … Read more
The theme functions file name must be called functions.php not function.php. This can cause your code to not implement? You must check carefully.
Use get_queried_object_id() to get the post ID of the current page/post when viewing a single page or post, regardless of whether or not you’re in the loop, or what the global $post variable happens to be at that moment: if ( is_page() || is_single() ) { $post_id = get_queried_object_id(); $meta_alternate = get_post_meta( $post_id, ‘extra_meta_alternate’, true … Read more
Okay, here’s the answer: function CustomHead() { include(‘headcontent.php’); } add_action(‘wp_head’,’CustomHead’,1,1); The key is that first “1”, which sets the priority of it to run at the highest (this is an optional element, defaulting to 10, putting it at the end of the head by default). More info here: http://codex.wordpress.org/Function_Reference/add_action
While you can practically control order of hooked things by priority, it’s not always the right tool for the job. In case of styles you should be using appropriate wp_enqueue_style() function which allows you to easily set up elaborate dependencies which will be automagically processed by WP to produce desired order of styles output. Unfortunately … Read more
You define priority. It’s not a hack. Maybe it’s that you’re looking for is PHP_INT_MAX which is a PHP constant. So you can put it as priority number.
I just skimmed through the WPSEO_Frontend class and found the wpseo_robots filter for the meta robots content string. You might try something like: add_filter( ‘wpseo_robots’, function( $content ) { // your logic here … return $content; } ); to override the robots meta content from that plugin. ps: You should consider moving the add_action out … Read more
This function doesn’t take any params, so there is no nice way of doing it. But of course you can do this PHP way using output buffering 😉 ob_start(); wp_head(); $var = ob_get_clean();
