Look at F:\sites\wp-git\wp-admin\js\common.js: $(‘div.updated, div.error’).not(‘.below-h2, .inline’).insertAfter( $(‘div.wrap h2:first’) ); If your notice has the class updated or error, it will be set after the first h2 automatically. When you create custom messages, make sure you are using one of these classes. Then you can just append them to body, and WordPress will move them to … Read more
Per comments, you need to check for have_comments() first, before using any of the comment-template functions such as get_comment_author(), otherwise they try to call methods on a null comment object, producing PHP warnings.
If $wp_query->post_count == 0 I cant see how $wpdb->get_results( $wp_query->request ) would return any posts. So basically $request = $wpdb->get_results( $wp_query->request ); contains nothing and $request[0] doesn’t exist. Ergo PHP Notice: Undefined offset: 0 It would be interesting to know, what this could is supposed to achieve.
Yes, this is possible (but a pain). Admin messages are creating when WordPress runs this line in admin-header.php: do_action( ‘admin_notices’ ); The action called before this one is: do_action( ‘in_admin_header’ ); So, we can hook in there and run some code to make some changes to filter out messages before WordPress can render them. First … Read more
I found the answer. Notices in the Block Editor would require JavaScript code. ( function( wp ) { wp.data.dispatch(‘core/notices’).createNotice( ‘error’, // Can be one of: success, info, warning, error. ‘Error Message.’, // Text string to display. { isDismissible: true, // Whether the user can dismiss the notice. // Any actions the user can perform. actions: … Read more
If I were to hazard a guess, I would say you recently started using a theme or plugin or that one of those was recently updated. The error indicates that things are happening in the wrong order. This is not critical but somewhere some expected feature is probably not happening quite the way it was … Read more
The 3rd parameter for the function accepts a private option named __unstableHTML which if true, then enables HTML in the notice message/content: createNotice( ‘success’, ‘Post published.<br /> Line 2. Should work in WordPress 5.8.’, { __unstableHTML: true, // true = allows HTML; default false isDismissible: true, actions: [ … ], } ) However, in the … Read more
It must be pretty late in the action order because I’ve tried hooking to admin_notices from it and it doesn’t work. $function callback (param of add_submenu_page) is used to output the content of admin pages, so it runs when WordPress is actually displaying the markup (body) of page. That should be pretty clear because you … Read more
There is an action, ‘core_upgrade_preamble’, which can be added to output anything you would like at the bottom of the upgrade-core page. For example, try: add_action(‘core_upgrade_preamble’, ‘add_custom_upgrade_core_message’); function add_custom_upgrade_core_message(){ echo “<p>HI THERE</p>”; } That should work to meet your needs.
You could filter the_content: add_action( ‘post_updated’, ‘wpse105892_add_message’, 10 ); function wpse105892_add_message() { add_filter( ‘the_content’, ‘wpse105892_display_message’ ); } function wpse105892_display_message( $content ) { // remove the action once it’s run remove_action( ‘post_updated’, ‘wpse105892_add_message’, 11 ); $content = “<div class=”your-message”>You did it!</div>\n\n” . $content; return $content; }
