Do not rely on globals like get_the_ID() or get_post() do. Use the parameters for your callbacks. You get the current post object twice: When you register the metabox, you get the post object as a second parameter. When your output callback is called, you get it as the first parameter. Here is an example showing … Read more
esc_textarea shouldn’t strip out newlines — It’s just a thin wrapper around htmlspecialchars: http://core.trac.wordpress.org/browser/tags/3.3.2/wp-includes/formatting.php#L2536 <?php function esc_textarea( $text ) { $safe_text = htmlspecialchars( $text, ENT_QUOTES ); return apply_filters( ‘esc_textarea’, $safe_text, $text ); } That said, there are lots of options. What do you want your users to do have the ability to post? esc_html will … Read more
Not really, attachments are still not “full post types”. Manny Flerumond hints this quite well in this thread: Was thinking about this the past few days: currently any media files uploaded to a WordPress site defaults to the post status of inherit, which is a holdover to when media attachments were just that. Media was … Read more
You missed one argument in the $args for add_meta_box. The correct use would be (Codex): add_meta_box( $id, $title, $callback, $post_type, $context, $priority, $callback_args ); You forgot to set the context, add it and you should be fine. add_meta_box( ‘content-on-page’, ‘Content On Page’, ‘ila_render_meta_box’, ‘page’, ‘normal’, // add this line ‘high’ );
The second parameter of selected() has to agree with the value attribute of the current <option>. So assuming you have stuffed $selected with the value given by the relevant get_post_meta(), the following should work for you: <label for=”myplugin_meta_box_select”>Status:</label> <select name=”myplugin_meta_box_select” id=”myplugin_meta_box_select”> <option value=”Approved” <?php selected( $selected, ‘Approved’ ); ?>>Approved</option> <option value=”In Progress” <?php selected( $selected, … Read more
How can I search it by metadata? As far as I know, there’s no standard/built-in way of doing that (for the time being). But with custom coding, you can make it possible: You can append a city to the query string: /wp-json/wp/v2/horario_busao?city=London And then use the rest_{$this->post_type}_query filter to set the meta key/value pair which … Read more
Try metadata_exists( ‘post’, $post->ID, ‘display_sharing_buttons_save’ ) This functions determine if meta-key exists and return true even with NULL value. So in your case, if it returns FALSE you can show CHECKED by default. Source
If your posts page is a static page selected under Settings > Reading > Front page displays, then get_queried_object_id() will return the ID for that page which you can use to fetch meta data. $check_meta = get_post_meta( get_queried_object_id(), ‘checkbox’, true ); $header_meta = get_post_meta( get_queried_object_id(), ‘header’, true ); $textarea_meta = get_post_meta( get_queried_object_id(), ‘textarea’, true );
Not mine but modified from here. But if you pop this into functions.php or a plugin it will work. add_filter( ‘gettext’, ‘change_publish_button’, 10, 2 ); function change_publish_button( $translation, $text ) { if ( ‘yourcustomposttype’ == get_post_type()) if ( $text == ‘Publish’ ) return ‘Save’; return $translation; }
apply_filters requires the first argument to be the name of the hook, the second argument to be the value to be modified (optional) subsequent arguments to be passed to the filters. See the Codex
