Using filters we can modify the props and attributes of blocks. First we extend the attributes to include the new attribute: const { addFilter } = wp.hooks; // Register/add the new attribute. const addExtraAttribute = props => { const attributes = { …props.attributes, extra_attribute: { type: “string”, default: “default_value” } }; return { …props, attributes … Read more
WordPress saves them in the databas in wp_usermeta as serilized array. For the dashboard all are registered in meta-box-order_dashboard if the meta-box(s) are in metaboxhidden_dashboard they will not be shown. The order will be as saved in database and if not in metaboxhidden_dashboard. Example the dashboard: KEY: meta-box-order_dashboard VALUE: Array ( [normal] => dashboard_right_now,dashboard_recent_comments,dashboard_incoming_links,dashboard_plugins [side] … Read more
You can do it using Widget Context plugin or Widget Logic plugin. They work fine. I prefer Widget Context because it has more flexibility.
I have worked on your issue and found a solution after some Google. Note: Add the below mentioned code to theme’s functions.php or any plugin’s file. Code: This filter function will add a custom tab to the Products Data metabox <?php add_filter( ‘woocommerce_product_data_tabs’, ‘add_my_custom_product_data_tab’ , 99 , 1 ); function add_my_custom_product_data_tab( $product_data_tabs ) { $product_data_tabs[‘my-custom-tab’] … Read more
That depends entirely on what you mean by “attach.” Each WordPress post can already have multiple media attachments – photos, documents, etc. You upload these using the built-in uploader and they’ll all be marked as “attached” to that specific post ID. You can refer to these later programatically elsewhere. For example, the following code will … Read more
It is hard to declare best practices here. The placement depends on the content of the metabox: an editor field would be too narrow usually in the side column; two small checkboxes on the other hand will look lost in the main column. To understand where which box will be placed, let’s use a small … Read more
To display a metabox collapsed or closed by default, it is good to know that adding closed to it’s class attribute will display it closed. All meta-boxes main divs that have closed in their classname, are displayed in the closed form. When the arrow is clicked it will be removed or added (toggled). This is … Read more
On remove_meta_box is a note: Because you can’t remove a meta box until it’s been added, it’s important to make sure your call to remove_meta_box() happens in the right sequence. WordPress SEO adds meta boxes on add_meta_boxes action with default priority – 10, which run after admin_init, so that won’t remove them. Instead you need … Read more
I haven’t had time to test this but this looks like it should work for you. add_action(‘do_meta_boxes’, ‘remove_thumbnail_box’); function remove_thumbnail_box() { remove_meta_box( ‘postimagediv’,’post’,’side’ ); } Check this for more info. Edit: The main change here is that you need to attach the function to do_meta_boxes instead of admin_menu
I came up with a solution for your first question. i.e the tax metabox that only suggests terms from existing terms list but does not allow you to add new terms. The solution is jQuery based and modifies the default behavior of the tags (i.e non heirarchical taxonomies) meta box. Limitation: Currently it only allows … Read more
