Adding and removing columns from the admin pages panel

How can I add a menu item to the admin area?
The code itself is fine. But you would need to activate the plug-in: you can’t simply place the file in the plug-ins directory. You will need to give the plug-in a ‘header’ too. See the Codex. Alternatively, place the code in your theme’s functions.php, but really it should be in a plug-in.
Post editor is 89953px tall. How to fix?
Goodness, that’s pretty funny! Try clearing your cookies. Specifically, there should be a cookie named “TinyMCE_content_size” which is most likely your culprit.
Limiting Admin Backend Search to Title
This is possible by altering the search query via the posts_search hook. http://core.trac.wordpress.org/browser/tags/3.3.1/wp-includes/query.php#L2202 A default search query will look like this: ..AND (((wp_posts.post_title LIKE \’%search terms%\’) OR (wp_posts.post_content LIKE \’%search terms%\’))) We need to remove the post content search, a regular expression should be enough. add_filter( ‘posts_search’, ‘wpse_45153_filter_search’, null, 2 ); function wpse_45153_filter_search( $search, $a_wp_query … Read more
remove menus for a specific role?
Here is your answer: function remove_menus () { global $menu; if( (current_user_can(‘install_themes’)) ) { $restricted = array(); } // check if admin and hide nothing else { // for all other users if ($current_user->user_level < 10) $restricted = array(__(‘Dashboard’), __(‘Posts’), __(‘Media’), __(‘Links’), __(‘Pages’), __(‘Appearance’), __(‘Tools’), __(‘Users’), __(‘Settings’), __(‘Comments’), __(‘Plugins’)); // this removes a lot!

admin_enqueue_scripts not rending JS file correctly
You action filter is wrong. First change this function name function register_scripts , it’s a bad name, use something unique. Second change add_action (“admin_print_styles-post.php”, “payee_init”); to a proper hook like add_action (“wp_enqueue_scripts”, “payee_init”); http://codex.wordpress.org/Function_Reference/wp_enqueue_script
Simply poll & Events Calendar plugins clashing
It might be due to the position on the admin sidebar in Simply Poll. Go to simply-poll/lib/admin.php and on line 40 remove the , 6 from the end of the add_menu_page() function and see what happens. I’ll have a look at the other plugin as well to check what they are doing. Simply Poll developer
Get categories names as an array to use it in theme settings
Thanks Michael for the tip. I finally got it. The solution is as follows: $options[] = array( “section” => “zzz”, “id” => HS_SHORTNAME . “_multicheckbox_inputs”, “title” => __( ‘Multi-Checkbox’, ‘hs_textdomain’ ), “desc” => __( ‘Some Description’, ‘hs_textdomain’ ), “type” => “multi-checkbox”, “std” => ”, “choices” => my_list_cats() ); And in functions.php: function my_list_cats() { $cats … Read more
creating a plug in that would tap into save/update action of posts [closed]
I don’t know of any plugins that do this, and I’m not sure you’ll find one. The closest I can find is the “Mandatory Field” plugin. The specific tasks that you might want are so varied, that I wonder whether a non-bloated plugin that let you customize the validation is out there. With that said, … Read more
avoiding the display of certain categories to certain user roles at content entry time
It uses get_terms and wp_get_object_terms internally to get the categories. You can achieve what you want using a filter associated with these functions. <?php //$args = apply_filters( ‘get_terms_args’, $args, $taxonomies ); add_filter(‘get_terms_args’, ‘wpse53900_filter_cat’); function wpse53900_filter_cat($args, $taxonomies){ //this is where you can check the taxonomies and roles to filter out the ones you want //additionally, make … Read more
