The function submit_button() does generate: <input type=”submit” name=”submit” id=”submit” class=”button button-primary” value=”Save Changes” /> As seen on the codex documentation page. Which gives you the possibility to check for a $_POST or, depending on the form, $_GET or generic $_REQUEST variable – to be exact for $_POST[ ‘submit’ ] or $_GET[ ‘submit’ ] or $_REQUEST[ … Read more
By default this is not possible. There are workarounds if you do it the OOP way. You could create a class to store the values you want to use later. Example: /** * Stores a value and calls any existing function with this value. */ class WPSE_Filter_Storage { /** * Filled by __construct(). Used by … Read more
What you can do is use the get_current_screen() function to get what screen the current user is on ( in the admin panel ) and only add those global values whenever the user is viewing the post page: function my_format_TinyMCE( $in ) { $screen = get_current_screen(); if( is_object( $screen ) && ‘post’ == $screen->post_type ) … Read more
As deduced from the comments, and the source code, the ID for new posts is only generated after the hook wp_insert_post_data, the wordpress codex is misleading in this regard.
This action hook (found in /wp-admin/edit-tags.php) will output the button below the table (not quite where you have asked to position it, but it is an easily available action and outside the form table.) $taxonomy = ‘location’; // you will probably need to change this add_action(‘after-{$taxonomy}-table’,’custom_export_button’); function custom_export_button($taxonomy) { $export_url = admin_url(‘admin-ajax.php’).’?action=export_taxonomy’; echo “<form action='”.$export_url.”‘ … Read more
More importantly you should notice what link is produced by get_delete_post_link(). It’s an admin link is_admin() check will be always true. Instead you need something else that helps match the request. Try adding and query arg to your delete link. add_query_arg( ‘origin’, ‘fe’, get_delete_post_link( get_the_ID() ) ); then in the action add_action(‘deleted_post’, ‘woffice_trashed_post_handler’, 10); function … Read more
You need to limit yourself to the main loop and this can be done by checking if is_main_query returns true. This might not be enough as that hook/filter was probably designed with the intention of augmenting the summery and therefor might be called more then once even during execution of the main loop itself. You … Read more
I have added extra rewrite rules for pages with no item_width and item_height in combination with pagination as follows: /** * Adds rewrite rules for shop category */ function gtp_add_shop_rewrite_rules() { // shop-category/category/item_width/item_height/page/2/ add_rewrite_rule( ‘^shop-category\/([^/]*)\/([^/]*)\/([^/]*)\/page\/([0-9]*)$’, ‘index.php?shop-category=$matches[1]&item_width=$matches[2]&item_height=$matches[3]&paged=$matches[4]’, ‘top’ ); // shop-category/category/page/2/ add_rewrite_rule( ‘^shop-category\/([^/]*)\/page\/([0-9]*)$’, ‘index.php?shop-category=$matches[1]&paged=$matches[2]’, ‘top’ ); // /shop-category/category/item_width/item_height/ add_rewrite_rule( ‘^shop-category\/([^/]*)\/([^/]*)\/([^/]*)$’, ‘index.php?shop-category=$matches[1]&item_width=$matches[2]&item_height=$matches[3]’, ‘top’ ); // /shop-category/category/item_width/ add_rewrite_rule( … Read more
Use a static method – the add_action will fire for each instantiation, but the hook will only be registered once: add_action( ‘wp_enqueue_scripts’, __CLASS__ . ‘::planner_load_scripts’ ); static public function planner_load_scripts() { }
WordPress has a fairly good roles and capabilities system already and, IMHO, you’d find it easier working with that. When the admin menu is constructed, every item on the admin menu is subject to a check on a relevant capability. Similarly every attempt to use an admin screen is checked. It’s possible to use map_meta_cap … Read more
