Here’s a great codex article on the topic of creating administration theme: http://codex.wordpress.org/Creating_Admin_Themes And back to your question, you will want to load different stylesheets for different user roles, so you have to check who the current user is. Pay attention, the check is done using current_user_can() function and checking for administrator is not being … Read more
The <br> tag is coming from wpautop(), which is one of a number of display filters added to the content via wp-includes/default-filters.php: // Display filters add_filter( ‘the_content’, ‘wptexturize’ ); add_filter( ‘the_content’, ‘convert_smilies’, 20 ); add_filter( ‘the_content’, ‘wpautop’ ); add_filter( ‘the_content’, ‘shortcode_unautop’ ); add_filter( ‘the_content’, ‘prepend_attachment’ ); add_filter( ‘the_content’, ‘wp_make_content_images_responsive’ ); … // Shortcodes add_filter( ‘the_content’, … Read more
You need to use wp_script_is in order to check if the library you are willing to use has already been included by another plugin. As you can see the handle is important, if you change it to whatEverIWant.js, it will not recognize the library.
Admin pages are basically spoken nothing else then a hook to a function, so it is technically not a problem to add your own pages without making use of the menu. I was not aware of an API function that allows you to register own pages with ease, but there is a helper function in … Read more
Try: <?php $class = new MyClass(); class MyClass { public function MyClass() { add_action(‘init’, array($this, ‘core’)); } public static function core() { echo “I never get to here”; } } ?>
You’re on the right track with creating the plugin. All your assumptions are correct. To avoid errors on activation you’ll want to wrap the functions that you are redefining in function_exists blocks, as on activation those functions will already be defined: if ( ! function_exists( ‘wp_hash_password’ ) ) : function wp_hash_password( $password ) { return … Read more
There’re two very often forgotten action ref arrays: loop_start/_end(). Just turn on output buffering and you’re ready to go. add_action( ‘loop_start’, ‘wpse75307_plugin_loop’ ); add_action( ‘loop_end’, ‘wpse75307_plugin_loop’ ); /** * Callback function triggered during: * + ‘loop_start’/`have_posts()` after the last post gets rendered * + ‘loop_end’/`the_post()` before the 1st post gets rendered * @param object \WP_Query … Read more
In your example, there is currently no difference. You get the same object, if there is one. Try it: global $current_screen; $current_screen->foo = 1; $screen = get_current_screen(); $screen->foo = 2; echo ‘$current_screen->foo: ‘ . $current_screen->foo; // 2! The simple reason: objects are not passed as a copy in PHP. But: global variables are really bad, … Read more
WordPress itself is not very object oriented – it has objects (like WP_User, for example), but most interactions with the core API take place through plain function calls. It also depends widely on global state, though it does a good job of managing this through the abstractions of actions and filters. In my experience there … Read more
There is no regular output and hence no header sent before template_redirect on the front end. If you need sessions on the back end too, use the action wp_loaded to cover both. Example: add_action( ‘template_redirect’, function() { $status = session_status(); if ( PHP_SESSION_DISABLED === $status ) { // That’s why you cannot rely on sessions! … Read more
