This code should work in your functions.php add_shortcode(‘gallery’, ‘custom_gallery_function’); function custom_gallery_function($atts) { $user = wp_get_current_user(); // if current user isn’t admin, add posts to be hidden to exclude if(!in_array(‘administrator’, $user->roles)) $atts[‘exclude’] = $atts[‘exclude’] . ‘,’ . $atts[‘hide’]; // call the wordpress shortcode function return gallery_shortcode($atts); }
I’m not sure how plugin hooks would impact in any way the solution to your problem. The home.php template file gets included at the template_redirect action, which fires well-before wp_head. That said, what it sounds like you want to do is: Have ‘posts_per_page’ = 1 on the first page of the blog posts index Have … Read more
I believe you are talking about the admin_bar which has many hooks. You can read more about wp_before_admin_bar_render and wp_after_admin_bar_render in codex and actually wp source.
In WordPress 3.5, this hook works for me: add_action( ‘print_media_templates’, ‘wpse_75746_print_style_35’ ); function wpse_75746_print_style_35() { ?> <style> .media-modal-content, .media-sidebar { background: #FFF2D4 !important; } </style> <?php } In 3.4.2, this is the one: add_action( ‘admin_print_styles-media-upload-popup’, ‘wpse_75746_print_style_342’ ); function wpse_75746_print_style_342() { ?> <style> #media-upload { background: #FFF2D4 !important; } </style> <?php }
Much probably, using debug_backtrace in this fashion is wild hackerism… Based on @toscho’s tip, the following achieves the same results: add_filter( ‘get_blogs_of_user’, ‘reorder_users_sites’ ); function reorder_users_sites( $blogs ) { if( !did_action( ‘wp_before_admin_bar_render’ ) ) uasort( $blogs, ‘bf_uasort_by_blogname’ ); else uasort( $blogs, ‘bf_uasort_by_domain’ ); return $blogs; }
What’s wrong with good old do_action? 😉 You could write a simple wrapper: function wpse81578_hook( $hook ) { do_action( $hook ); } If you’re looking for something dynamic, take a look at the do_atomic function of the Hybrid theme framework: it “adds contextual action hooks to the theme. This allows users to easily add context-based … Read more
You might check out the content_edit_pre filter. Your example would then look like this: function wpse89725_pre_edit_content( $content, $post_id ) { $content = “nothing”; return $content; } add_filter( ‘content_edit_pre’, ‘wpse89725_pre_edit_content’, 10, 2 ); You can read more about this filter in the Codex: https://codex.wordpress.org/Plugin_API/Filter_Reference/content_edit_pre Edit: You can also try the edit_post_content filter: add_filter( ‘edit_post_content’, ‘my_pre_edit_content’, 10, … Read more
In your functions.php file you should add an action to enqueue your scripts. <?php function my_enqueue_scripts() { wp_enqueue_script( ‘load_post’, get_template_directory_uri() . ‘/js/load_post.js’, array( ‘jquery’ ), ‘1.0’, 1 ); wp_localize_script( ‘load_post’, ‘wp_ajax’, array( ‘url’ => admin_url( ‘admin-ajax.php’ ), ‘nonce’ => wp_create_nonce( ‘ajax_nonce’ ) ) ); } add_action( ‘wp_enqueue_scripts’, ‘my_enqueue_scripts’ );
WordPress does not concatenate the entire page into a string before printing it which is what would have to happen to “capture” the whole page template. Much of the page echos as it occurs– think about template tags like the_content and the_title which don’t return strings. The just echo them. You’d have to use output … Read more
Using a snippet of code like this: $hook_name=”the_content”; global $wp_filter; var_dump($wp_filter[$hook_name]); I was able to find a list of all hooked callback functions to the WordPress filter: the_content. I then located a few possible culprits, then searched for their function existence. After narrowing down my list, I came to the conclusion on the hooked callback … Read more
