) first thanks a lot to @swisspidy and the suggestion to modify $_POST on the init hook. but after a bit of more thinking and looking at the code i took a different approach. instead of fixing things afterwards, after the form submit, i decided to fix things via jQuery during the form submit and … Read more
add_action( ‘manage_posts_custom_column’, ‘id_data’ ); add_filter( ‘manage_posts_columns’, ‘id_column’ ); function id_column( $defaults ) { $defaults[‘id’] = ‘ID’; return $defaults; } function id_data( $column_name ) { global $post; switch ( $column_name ) { case ‘id’: echo $post->ID; } }
After looking in cart.php, it doesn’t look like you can do that with hooks, as there is static html that wraps around the product price content. That product price content is what is affected by the woocommerce_cart_item_price hook that you’ve tried, but not the containing static html markup for the column structure itself. The good … Read more
The answer by @motivast is correct. However, to avoid using a billion echo and apostrophes, you can simply close the PHP tag and open it after your script: function wpse_287665_mobile_menu_script() { ?> <script> jQuery(document).ready(function($){ $(“button.menu-toggle”).click(function(){ if( $(“button.menu-toggle”).attr(“aria-expanded”) == “true” ) { $(“button.menu-toggle”).attr(“aria-expanded”, “false”); $(“ul#top-menu”).attr(“style”, “display:none;”); } else { $(“button.menu-toggle”).attr(“aria-expanded”, “true”); $(“ul#top-menu”).attr(“style”,”display:block;”); } }); }); </script><?php … Read more
You need to echo your data. Try this instead – function add_link_to_aff() { $html_output = “<li><a href=”#”>” . __( ‘Test’, ‘yith-woocommerce-affiliates’ ) . “</a></li>”; echo $html_output; } add_action( ‘yith_wcaf_after_dashboard_links’, ‘add_link_to_aff’, 10 );
With the filter single_post_title, you can change the page/post title that is set in the <head><title>Page title</title></head>. If you want to change the title that you see in the page header. ( Which i think you want to do). Use this filter: add_filter(‘the_title’, ‘modify_all_titles’, 10, 2); function modify_all_titles($title, $id) { return ‘SOME TEXT BEFORE TITLE … Read more
Correct way of modifying a variable using hooks If you want to modify a variable or any value using hooks, it’s best to do that using filter hooks (instead of action hooks). Although internally the implementation is almost the same for actions and filters, the convention is: With action hooks, you do something, echo output … Read more
Main problem with your code is that you use wp_login action. The wp_login action hook is triggered when a user logs in by the wp_signon() function. It is the very last action taken in the function, immediately following the wp_set_auth_cookie() call. So first of all – the user is already authenticated and his auth cookie … Read more
The remove_filter() is necessary to avoid the callback from being called recursively, which would result in a memory issue due to a never-ending function execution. And that recursion could happen because the callback is hooked to get_post_metadata which is invoked via the get_metadata() function which the callback calls. So you need to first “unhook”/unregister the … Read more
manage_users_custom_column is a filter hook, so you should use add_filter() and not add_action(). Which also means you should return the output instead of echoing it. The column name is the second parameter and not the first one — which is the current value for the current column. So try with: function last_name_value($output, $column_name, $user_id) { … Read more
