Removing wp_head will have some negative effects as it won’t allow you to use virtually 90% of the plugins on wordpress.org. Also some of that code you are seeing only shows up when you are logged in (unless your theme is specifically adding it). For example, the dashicons, open sans, and admin-bar stylesheets and inline … Read more
You have the right approach. You will want to use the admin_enqueue_scripts hook: add_action( ‘admin_enqueue_scripts’, ‘wpse_239302_hide_action_links’ ); function wpse_239302_hide_action_links() { global $pagenow; if ( $pagenow == ‘plugins.php’ ) { ?> <style type=”text/css”> .visible .proupgrade, .visible .docs, .visible .forum, .visible .jetpack-home, .visible .support { display: none; } </style> <?php } }
Check this question How does wordpress restrict X-FRAME to sameorigin?. The questioner’s issue was resolved by modifying his site’s .htaccess file by adding the below line to it as his Web Host set the X-Frame-Option. Header always unset X-Frame-Options You can check if that works for you.
Do this on template_redirect hook. You can use wp_safe_redirect to redirect to different page in the blog. I can’t give you the code because I don’t from where you are getting the $user
Use the Authorization header. Example: $auth = base64_encode( $username . ‘:’ . $password ); $args = [ ‘headers’ => [ ‘Authorization’ => “Basic $auth” ], ‘body’ => $body, ]; $response = wp_remote_post( $url, $args ); $response_body = wp_remote_retrieve_body( $response );
There are filters for allowed_http_origins and add_allowed_origins. You can use them to set the proper Access-Control-Allow-Origin header in the response to your AJAX call. Add this to your theme’s functions.php file: add_filter(‘allowed_http_origins’, ‘add_allowed_origins’); function add_allowed_origins($origins) { $origins[] = ‘https://www.yourdomain.com’; return $origins; }
You can add html to the site head using this function: // Add scripts to wp_head() function add_head_html() { ?> <!– html goes here –> <?php } add_action( ‘wp_head’, ‘add_head_html’ ); But if you’re talking about the html element <header> (as it sounds like from your edits) it sounds like overcomplicating things, but you might … Read more
Move your download/output code into admin_init hook. This hook is called before anything is output. It should work. <?php /* Plugin Name: Your Site’s Functionality Plugin Description: All of the important functionality of your site belongs in this. Version: 0.1 License: GPL Author: Your Name Author URI: yoururl */ add_action(‘admin_menu’, ‘my_page_export_menu’); add_action(‘admin_init’,’wpse9876_download_csv’); function my_page_export_menu() { … Read more
As you said per page/post basis, this would work for each post add_action(‘wp_head’, ‘add_link_in_head’); function add_link_in_head() { global $post; if(!empty($post)) { $alternate = get_post_meta($post->ID, ‘alternate’, true); $hreflang = get_post_meta($post->ID, ‘hreflang’, true); if(!empty($alternate) && !empty($hreflang)) { ?> <link rel=”alternate” href=”https://wordpress.stackexchange.com/questions/110260/<?php echo $alternate; ?>” hreflang=”<?php echo $hreflang; ?>” /> <?php } } } If there is no … Read more
