First, I think you’re confusing the wp_nav_menu() args. The ‘menu_class’ parameter defines the class added to the menu element, which by default is <ul>, as per the ‘items_wrap’ parameter. The default ‘menu_class’ is ‘menu’, which results in <ul class=”menu”>. The real issue is actually the fallback_cb – the callback used when no menu is defined … Read more
I’m pretty sure you try to use this conditional tags to early, so they don’t work. From Codex: Warning: You can only use conditional query tags after the posts_selection action hook in WordPress (the wp action hook is the first one through which you can use these conditionals). For themes, this means the conditional tag … Read more
This is a very simple PHP issue, unrelated to WordPress. You need to check if the value is empty before echoing it. So, store them as variables first: $twitter = get_the_author_meta(‘twitter’, $author_id); $facebook = get_the_author_meta(‘facebook’, $author_id); //etc Then check them before displaying: if(!empty($twitter)) { echo ‘<a title=”Follow me on Twitter” href=”‘.$twitter.'”><img src=”twitter.png” alt=”” /></a>’; } … Read more
The functions.php file executes at plugins_loaded, with the Child Theme functions.php executing before the Parent Theme functions.php. That means that, in order to load functional sub-files in the Child Theme after the Parent Theme functions.php executes, you simply need to hook your include() calls after plugins_loaded. A usually safe action for such purposes is after_setup_theme: … Read more
Nearly all functions in esplanade can be overwritten in a child theme. Take the esplanade_admin_header_style() function for instance. Just before that function is the following line of code if ( ! function_exists( ‘esplanade_admin_header_style’ ) ) : . The important part here is if ( ! function_exists()): This means that the function it calls can be … Read more
If you a look at the source you’ll see it’s because the sanitize_title filter fires after remove_accents() is called by sanitize_title(). It does however, pass the raw title as the second argument so you can perform any substitutions on the raw title, apply remove_accents() and return it: function wpsesanitize_title_extra( $title, $raw_title, $context ) { $new_title … Read more
It is required, actually. There’s no real difference between themes and plugins as such. Neither of them should take actions on merely being loaded, they should use action hooks on functions to have things happen in the correct ordering.
You can just add a check: if ( ! empty ( $post->post_parent ) ) { $parent_title = get_the_title($post->post_parent); echo “<h1>$parent_title</h1>”; } or use setup_postdata(): setup_postdata( $post->post_parent ); the_title( /* arguments here*/ ); wp_reset_postdata();
Not tested, but it might work, use wp_logout_url() wordpress in built function to get logout url. // Add a Login hyperlink to the secondary navigation menu if the user is logged-out function wpa_remove_menu_item( $items, $menu, $args ) { if( is_admin() || ! is_user_logged_in() ) return $items; foreach ( $items as $key => $item ) { … Read more
The get_hidden_meta_boxes function (source link) provides two filters that you can use to hide the meta box. (Pick just one of them.) The first is default_hidden_meta_boxes (source), adding the metabox to the $hidden array will hide the metabox by default, but the user can select the screen options tab and choose to enable it. The … Read more
