You can easily inspect all the metadata for any post like so: // 123 is the (attachment) post ID var_dump( get_post_meta( 123 ) ); And in a default WordPress setup with no plugins or theme which add custom metadata to the image attachment post, the metadata you’d get are: _wp_attached_file — string, the image file … Read more
You could set the ‘depth’ argument to 1 in your wp_nav_menu() call to get only top level items, along with the custom menu walker, something like this: return wp_nav_menu( array( ‘menu’ => $name, ‘menu_class’ => ‘footer-menu’, ‘echo’ => false, ‘depth’ => 1, ‘walker’ => new custom_footer_menu_walker ) ); Add the custom menu walker to your … Read more
get_the_title() returns the post (product) title including all HTML, whitespaces and symbols not allowed in URLs, etc. Use post slug instead. Also, you don’t need to use any actions. function custom_hero_image( $post_id ) { $product = get_post( $post_id ); $slug = $product->post_name; if ( is_product( $post_id ) ) { $html=”<img class=”jarallax-img” src=””. get_template_directory_uri() .’/inc/assets/img/shop/hero/’.$slug.’.jpg”>’; } … Read more
I’m trying to get the wpdb class to read these values into an array to suit the function You could manually loop through the $results array to build the $pattern array, but a much simpler way is by using $wpdb->get_col() to get all the values of the unit_type column: $pattern = $wpdb->get_col( “SELECT unit_type from … Read more
The simplest advice is that you should never edit what are generally know as Core WordPress files, that includes adding new files within the wp-includes and wp-admin directories. The simple reason why this is not a good idea is that they are replaced when WordPres updates – deleting any changes or additional files – which … Read more
The bug is not in this snippet of code. The problem is with how you call wp_get_nav_menu_array, wherever that happens. The $current_menu is likely something invalid, so wp_get_nav_menu_items returns false, and thus you get the error that you get. You can see in user contributed notes an example of how to get a valid value … Read more
In short, (and as I said in the comments) in your function declaration, the $depth parameter should be defined as $depth = 0. And that’s because the original function (or class method) made it optional by setting a default value, so you should also do the same: function start_lvl( &$output, $depth = 0, $args = … Read more
wp_get_attachment_image_src() returns an array. You want wp_get_attachment_image_url(). $image = wp_get_attachment_image_url($user_meta, ‘thumbnail’);
I guess it doesn’t really matter, but I think it’s better to keep it as short as possible. Before, I used to put all of my logic in my functions.php file. But it was quick big at the end (like 2000 lines of code, sometimes more). Now, I prefer generate a sample theme thanks to … Read more
By default the login cookie lasts for 14 days if you tick ‘remember me’ 48 hours if you don’t So as a short term fix you probably want to tick ‘remember me’, and to extend that to 30 days you can add an auth_cookie_expiration filter e.g. function auth_cookie_expiration_30_days( $seconds, $user_id, $remember_me ) { if ( … Read more
