I added new field ‘picture’ (input type file) to category with help of these add_action(‘category_edit_form_fields’,’category_edit_form_fields’); add_action(‘category_edit_form’, ‘category_edit_form’); add_action(‘category_add_form_fields’,’category_edit_form_fields’); add_action(‘category_add_form’,’category_edit_form’); function category_edit_form() { ?> <script type=”text/javascript”> jQuery(document).ready(function(){ jQuery(‘#edittag’).attr( “enctype”, “multipart/form-data” ).attr( “encoding”, “multipart/form-data” ); }); </script> <?php } function category_edit_form_fields () { ?> <tr class=”form-field”> <th valign=”top” scope=”row”> <label for=”catpic”><?php _e(‘Picture of the category’, ”); ?></label> … Read more

add_menu_page and add_submenu_page both return the page’s “hook suffix”, which can be used to identify the page with certain hooks. As such, you can use that suffix in combination with the variable hooks admin_print_styles-{$hook_suffix} and admin_print_scripts-{$hook_suffix} to specifically target these pages. function my_menu() { $menu = add_menu_page( ‘Page 1’, ‘bar’, ‘something’, ‘else’, ‘foo’ ); $submenu … Read more
