Interesting Question! I’ve never seen repeatable fields used in Widgets. Giving a full Answer would require too much work/time, so I’ll give you links to the resources I know, and hopefully you’ll make this work and share the solution with us 😉 All this examples deal with Meta Boxes, you’ll need to copy the jQuery … Read more
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.
WordPress as a nice function is_active_widget that you can use in your __construct and test if the widget is present in the current page and add your scripts/styles based on that ex: function __construct() { parent::__construct(__CLASS__, ‘BasicWidget’, array( ‘classname’ => __CLASS__, ‘description’ => “This is a basic widget template that outputs text to the sidebar” … Read more
@JonathonByrd’s answer is probably ‘best’ – certainly you should using get_option if at all possible, since there’s no guarantee the option name will stay the same between WordPress versions. Similarly – @JonathonByrd also relies on using a global variable which may be removed/renamed (though perhaps very unlikely). Unfortunately there are no public wrappers which we … Read more
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
It’s usually best to copy the existing one, name it something unique, and then add your own functionality. Copy the WP_Widget_Recent_Posts class from wp-includes/class-wp-widget-recent-posts.php into your functions.php (or, preferably, another file in your theme devoted just to widgets) and rename to something else, like My_Widget_Recent_Posts Add your functionality in there. Don’t forget to call register_widget(‘My_Widget_Recent_Posts’) … Read more
try replacing : register_widget(‘States_Widget’); with: add_action(‘widgets_init’, ‘register_states_widget’); function register_states_widget() { register_widget(‘States_Widget’); }
I did battle with a similar situation recently. Ajax in widgets is no joke! Need to write some pretty crazy code to get things to work across instances. I’m not familiar with live query, but if you say it checks the DOM every second, I might have a less intense solution for you: var get_widget_id … 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
