If you upgrade your WordPress to 3.3.1, which you absolutely should, each widget area in the admin now has an ID you can use to target via CSS, which really should be enough. See http://core.trac.wordpress.org/ticket/18334 for an example.
I know this post is pretty old, but because I came across the same issue and this post came up higher than one with a solution, I figured I’d add this, which worked for me. Source: http://coffeecupweb.com/how-to-exclude-or-hide-categories-from-category-widget-in-wordpress-sidebar/ //Hide categories from WordPress category widget function exclude_widget_categories($args){ $exclude = “1,4,8,57,80”; $args[“exclude”] = $exclude; return $args; } add_filter(“widget_categories_args”,”exclude_widget_categories”);
Widget options are stored in the options table under ‘sidebars_widgets’ as a serialized array. See this post for a longer explanation. Changing the field per PHPMyAdmin is not recommended, use PHP, get_option() and update_option() instead, WordPress will take care for correct serialization then.
wp_print_scripts and wp_print_styles hooks are fired way before your widget function so that is way it’s not working. A solution to that would be to include the scripts in the footer using wp_print_footer_scripts hook, take a look at Jan’s answer to a similar question Or a much nicer solution take a look at Sorich’s answer … Read more
The edit_theme_options capability should allow the user to edit the sidebar as described on this page : http://codex.wordpress.org/Appearance_Widgets_SubPanel Code to add to functions.php $role = get_role(‘editor’); $role->add_cap(‘edit_theme_options’); Edit: This should work to prevent editor accessing themes or menus function custom_admin_menu() { $user = new WP_User(get_current_user_id()); if (!empty( $user->roles) && is_array($user->roles)) { foreach ($user->roles as $role) … Read more
I’ve been digging through the source code for a similar reason; I’d like to add the “Attachment Display Settings” to the default “select” frame. As far as I can tell, this can’t be done by passing parameters to wp.media(), as we would all like. wp.media currently has the two frames (“post” and “select”), and the … Read more
I solved this in Javascript. If you want to completely prevent it you should also do it server-side, because you can edit the widgets with Javascript disabled (try it out!). The different sidebars are checked when you drop widgets to them or away from them. If they become full, the background color changes and you … Read more
You can use the function is_active_widget . E.g.: function check_widget() { if( is_active_widget( ”, ”, ‘search’ ) ) { // check if search widget is used wp_enqueue_script(‘my-script’); } } add_action( ‘init’, ‘check_widget’ ); To load the script in the page where the widget is loaded only, you will have to add the is_active_widget() code, in … Read more
Great News, I’ve fixed it. Apologies for missing your gist in my initial comment and giving you an answer that you had already implemented. That’ll teach me to answer on my phone while on a train! Your use of ajaxstop is correct. Hell the JS for the most part is working correctly, you could see … Read more
Another solution is to add the columns setting back to the settings. function wpse126301_dashboard_columns() { add_screen_option( ‘layout_columns’, array( ‘max’ => 2, ‘default’ => 1 ) ); } add_action( ‘admin_head-index.php’, ‘wpse126301_dashboard_columns’ ); There is a related Trac ticket: #26354
