Admin Menus – Name Menu different from first Submenu [duplicate]

The first menu item typically is the parent item and shares the name with that item, you can however manually update the entry directly in the $submenu variable, like so.. add_action( ‘admin_menu’, ‘jp_create_admin_pages’ ); function jp_create_admin_pages() { global $submenu; add_menu_page(‘Members’,’Members’,’manage_options’,’members’,’jp_handle_admin_members’); add_submenu_page(‘members’,’Membership Types’,’Membership Types’,’manage_options’,’membership_types’,’jp_handle_admin_membership_types’); $submenu[‘members’][0][0] = ‘All Members’; } That way your parent keeps the original … Read more

Theme Customizer – Dynamic CSS PHP File

@s_ha_dum is right, the ajax plugin api is the way to go. I ran into this issue myself with a dynamic js file I was generating a little while ago.

Adding Google Analytics code to the tag of specific pages

While you can add the snippet directly to header.php, a better choice is probably the wp_head action which should be triggered in any well-made, modern theme. Using this hook allows you to insert the snippet without actually modifying your theme. It might look something like this: function wpse_282929_conditionally_print_ga_snippet() { if ( ! some_conditional_tag() ) { … Read more

Get list of shortcodes from content

Here’s one way: You can look at has_shortcode() and find the parsing there: preg_match_all( “https://wordpress.stackexchange.com/” . get_shortcode_regex() . “https://wordpress.stackexchange.com/”, $content, $matches, PREG_SET_ORDER ); using the get_shortcode_regex() function for the regex pattern. For non empty matches, you can then loop through them and collect the full shortcode matches with: $shortcodes = []; foreach( $matches as $shortcode … Read more

Bare minimum to include in PHP file to use WP functions? [duplicate]

You want to include wp-load.php or wp-blog-header.php not wp-settings.php or wp-config.php directly. If you look at the code in wp-load.php you will see why. wp-load.php looks for wp-config.php in several different places, including one level above the rest of the install. If you include wp-config.php directly the script will fail if wp-config.php has been moved. … Read more
