WordPress Backstage articles, categories, media, pages, comments, links, etc. all information in the display ID and set the ID to the first column

WordPress Background default is not to display the article, classification and other information ID, it is very inconvenient to view, do not know why the WP team for what reason default does not show this but can use Simply Show IDs Plugin to implement

Do not use plug-ins, other users of the implementation:

<?PHP/** * For WordPress background articles, categories, such as display ID from wpdaxue.com* ID by default added to the back of the column * http://www.wpdaxue.com/simply-show-ids.html* HTL add 2015-01-16*///Add a new column IDfunctionSsid_column ($cols){$cols[' SSID ']= ' ID ';return $cols;}//Display IDfunctionSsid_value ($column _name,$id){if($column _name= = ' SSID ')Echo $id;}functionSsid_return_value ($value,$column _name,$id){if($column _name= = ' SSID ')$value=$id;return $value;}//output various forms and CSS via action/filterfunctionSsid_add () {Add_filter (' Manage_posts_columns ', ' ssid_column '); Add_action (' Manage_posts_custom_column ', ' ssid_value ', 10,2); Add_filter (' Manage_pages_columns ', ' ssid_column '); Add_action (' Manage_pages_custom_column ', ' ssid_value ', 10,2); Add_filter (' Manage_media_columns ', ' ssid_column '); Add_action (' Manage_media_custom_column ', ' ssid_value ', 10,2); Add_filter (' Manage_link-manager_columns ', ' ssid_column '); Add_action (' Manage_link_custom_column ', ' ssid_value ', 10,2); Add_action (' Manage_edit-link-categories_columns ', ' ssid_column '); Add_filter (' Manage_link_categories_custom_column ', ' ssid_return_value ', 10,3);foreach(Get_taxonomies () as $taxonomy) {add_action ("Manage_edit-${taxonomy}_columns", ' Ssid_column '); Add_filter ("Manage_${taxonomy}_custom_column", ' Ssid_return_value ', 10,3);} Add_action (' Manage_users_columns ', ' ssid_column '); Add_filter (' Manage_users_custom_column ', ' ssid_return_value ', 10,3); Add_action (' Manage_edit-comments_columns ', ' ssid_column '); Add_action (' Manage_comments_custom_column ', ' ssid_value ', 10,2);} Add_action (' Admin_init ', ' Ssid_add ');?>

since neither of the above has been able to meet my requirements completely, I have made a change based on the above two to achieve my desired effect .
