On a single custom post type (for example), you can see the post meta. However on your homepage archive loop, you cannot because the theme uses a different template for this. Check out Template Hierarchy. The “home” page in _s is governed by the “index.php” template. In which we see: get_template_part( ‘content’, get_post_format() ); Since … Read more
As you can read in Codex about orderby and the WP_Query, you can use multiple orderby values as well: ‘orderby’ => ‘name meta_value’ simply by using a space in between. The available orderby values are listed in the Codex page. About your question: By default it should already work with your query. If it doesn’t, … Read more
The trouble is that save_post fires in lots of places other than the “edit post” screen – when it does, your code will think the checkbox is unchecked and overwrite your saved state. Add an additional hidden input to your meta box: <?php // Don’t global post, use the $post parameter already passed to the … Read more
Here is the description of transition_post_status from the codex: This function’s access is marked as private. That means it is not intended for use by plugin and theme developers, but only in other core functions. It is listed here for completeness. Use any of these functions instead. Why not use the publish_post action instead? There … Read more
Fields in database tables can not contain other types of data than text strings and numbers, and variations of them like dates and times. The field meta_value of wp_postmeta is a text field. So, when you store an array as meta_value you are really storing a string containing the serialized data that represents the original … Read more
The menu items boxes are created by the class Walker_Nav_Menu_Edit in wp-admin/includes/nav-menu.php. Thus to alter those boxes you’ll have to make your custom Walker I guess. But if you mean adding the new value to the nav menu meta-boxes (the boxes to the left side of the page) this will do the job: The function … Read more
I really like your clean class structure 🙂 But I have a suggestion that might fix things (based on my experience with nonces and meta boxes from a plug-in I built last weekend): Don’t try to create the nonce field manually. You currently have: $nonce = wp_create_nonce( plugin_basename( __FILE__ ) ); … <input type=”hidden” name=”argus_edit_visitor” … Read more
No, it’s not possible by using pre_get_posts alone. But you don’t have to use separate fields for the date. WP_Query, although doesn’t provide a simple query arg that would sort the posts by month and day only, you can use the posts_orderby filter hook to modify the ORDER BY clause (i.e. ORDER BY <the part … Read more
Your code should work in theory. Your failure is not caused by the code in your question but rather due to external factors. Something else is causing this failure DEBUGGING THIS ISSUE Turn on debug and check for obvious errors and warnings. This should be a good indication on the soundness of all your code … Read more
You’re calling get_post_meta() in two different ways: the first, leaving $single unset (it defaults to false) will get you the full array of meta entries for the given key; the second, setting $single to true, will get only the first item with that key. What you want, I believe, is an array of user IDs … Read more
