WordPress.org UI Style Guide site has some reference materials, including those on Box Formats and Forms. As far as I remember it’s not consistently maintained or considered especially canonical source. In practice elements are often done after studying current state of actual admin markup.
I approached by doing the opposite with using remove_meta_box() for the Slug metabox if the user is not an administrator or contributor: add_action( ‘admin_menu’, ‘wpse_237291_remove_slug_metabox’ ); function wpse_237291_remove_slug_metabox() { $user = wp_get_current_user(); $allowed_roles = array( ‘administrator’, ‘contributor’ ); if ( !array_intersect( $allowed_roles, $user -> roles ) ) { remove_meta_box( ‘slugdiv’, ‘post’, ‘normal’ ); } }
Using $_REQUEST is a bad practice. Between post requests, get requests, and cookies you can not be certain that you are processing actual user input and not some garbage left in the URL or in the browser’s memory. Meta boxes are “posted” so use only $_POST when processing them. The other aspect of your code … Read more
You could also code it like this : $btsvideoembeds = rwmb_get_value( ‘oembed_1’, array( ‘type’ => ‘oembed’ ) ); foreach ( (array) $btsvideoembeds as $btsvideoembed ) { printf(‘%s’, wp_oembed_get( $btsvideoembed ) );
You may have build your meta box wrong: If your custom field names are not valid variable names PHP will convert all characters not matching [a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff] to underscores. The reason: register_globals. A request field must be able to work as a variable. There are two workarounds: Name the field like an array: <input name=”foo[TrackNumber mp3.Artist]”>. … Read more
Again. If you are using file upload, it is different than image upload. To get a FILE url, use: $(html).attr(‘href’); File upload: window.send_to_editor = function(html){ var file_url = $(html).attr(‘href’); // Do something with those variables tb_remove(); }; Image upload: window.send_to_editor = function(html){ var file_url = $(‘img’, html).attr(‘src’), classes = $(‘img’, html).attr(‘class’), id = classes.replace(/(.*?)wp-image-/, ”); … Read more
In your save code, the value of $field[‘id’] is event_timeframe, which does not exist in $_POST, so your options will never save. You need to dig down into your options array to get to timestart and timeend: // loop through fields and save the data foreach ( $event_infobox_fields as $field ) { foreach ( $field[‘options’] … Read more
You could make use of wp_trim_words: <p><?php echo wp_trim_words( get_post_meta( $post->ID, ‘twpb_news_textnews’, true ), 55, ‘[…]’ ); ?></p> Or, if you want the filters applicable to the regular excerpts to be used as well, write your own wrapper for it: function wpse115106_news_excerpt( $text=”” ) { $excerpt_length = apply_filters( ‘excerpt_length’, 55 ); $excerpt_more = apply_filters( ‘excerpt_more’, … Read more
Choice between esc_url and esc_url_raw depends on the use you have to do with the url. If you have to use the url to display inside html use esc_url, E.g.: $my_link = get_post_meta( $post->ID, ‘mod_modbox_link’, true ); echo ‘<a href=”‘ . esc_url($my_link) . ‘”>Open link</a>’ esc_url_raw should be used for any other use, where the … Read more
