No, you don’t need output buffering in this case. As a rule of thumb: Don’t use output buffering unless you really have to. Just imagine what happens if someone else uses output buffering too from a plugin and it crosses with yours: // plugin ob_start(); // later, you in your theme ob_start(); // you call … Read more
Assign the menu to a string: $menu = wp_nav_menu( array ( ‘echo’ => FALSE, ‘fallback_cb’ => ‘__return_false’ ) ); if ( ! empty ( $menu ) ) { echo ‘<div class=”navmain2″>’ . $menu . ‘</div>’; }
The save_post action fires When a post is updated and/or published — including when a new post is inserted. <?php add_action( ‘save_post’, ‘wpse41912_save_post’ ); function wpse41912_save_post() { // do stuff } If you want your functions to fire only when a post is being edited, you can hook into edit_post. If you want it to … Read more
I was also trying to solve this problem and while searching for a solution, discovered that the nav_menu_css_class filter actually excepts a third parameter. This is an object containing variables related to your menu and includes the theme_location variable you can use to conditionally apply class names to a specific menu. You just need to … Read more
The correct way is to pass first argument as a unique string which acts as an identifier for the action & any additional arguments after that do_action(‘unique_action_tag’, $parameter1, $parameter2,,,, & so on); To attach functions to this action you’ll do // 10 is the priority, higher means executed first // 2 is number of arguments … Read more
Okay, I found a solution (and it can be used for any theme, with any plugin as it only uses core WordPress functions). In the menu, name the menu item where you want the user’s name to appear with a place-holder (see screenshot below). Example: #profile_name#, #user#, #random# Now, add the following code to the … Read more
You are acting on awfully big assumption that something like that would improve performance. Spoiler — no, it won’t. The load process in very loose terms consists of: Optionally running code responsible for looking up definitions (autoload or custom). Parsing the file or retrieving results from opcode cache. Loading results to be used. The “autoload … Read more
Try something like this: function realistic_get_first_embed_video($post_id) { $post = get_post($post_id); $content = do_shortcode(apply_filters(‘the_content’, $post->post_content)); $embeds = get_media_embedded_in_content($content); if (!empty($embeds)) { //check what is the first embed containg video tag, youtube or vimeo $counter = 0; foreach ($embeds as $embed) { // Check condition if count is 0 then // it is the first iteration if( … Read more
What is an alternative method to the WordPress private _doing_it_wrong() function? There’s no way that WordPress is ever going to get rid of the _doing_it_wrong() function, so it’s perfectly safe to use it. But if for some reason you don’t want to use it because it’s marked private, then you could create a plugin that … Read more
Try adding die(‘message’); and use that to debug where it fails. Also try and use ftp://external-server.com as opposed to just external-server.com. Also make sure you use your FTP password. And try it on active mode as opposed to passive mode. When I was trying to upload by FTP that’s what I had to do. Also … Read more
