Here’s the code. You can change $post_type and $custom_fields according to your needs. function extend_admin_search( $query ) { // Extend search for document post type $post_type=”document”; // Custom fields to search for $custom_fields = array( “_file_name”, ); if( ! is_admin() ) return; if ( $query->query[‘post_type’] != $post_type ) return; $search_term = $query->query_vars[‘s’]; // Set to … Read more
Do echo inside an if statement. function show_my_message() { $settings = get_option(‘wc_checkout_message_settings’); //Check if the array is set if( isset($settings[‘wc_checkout_message_text_field_0’]) && !empty($settings[‘wc_checkout_message_text_field_0’]) ){ echo $settings[‘wc_checkout_message_text_field_0’]; } //Check the other value and show it if(isset($settings[‘wc_checkout_message_text_field_1’]) && !empty($settings[‘wc_checkout_message_text_field_1’]) ){ echo $settings[‘wc_checkout_message_text_field_1’]; } }
To retrieve a value after using add_settings_field() you should use get_option(). So you could do something like this… $value = esc_html(get_option(‘option_name’)); if ($value) { echo ‘<a href=”‘ . $value . ‘”>Click Here</a>’; } You just need to change option_name to your field name. The code will grab the value and if it isn’t false echo … Read more
I don’t think ACF has a built-in function to do what you want. You can use get_field to retrieve a value from any post, but it requires a post ID if you want the value from anything other than the current post. So instead, we can query posts using WP_Query and pass the meta key … Read more
I strongly recommand you to use ACF (pro if you can, usefull for the repeater) : https://www.advancedcustomfields.com/ You can easily add custom field and link them to post type, and link post type to each other (this answers your two first questions). For the third, I guess it will depend how you could implement this
I figured it out after adding the same code to a different site I run. It was working fine on that site with the same theme and mostly the same plugins. I narrowed it down to another function I made (thankfully it wasn’t another plugin). The other function was sorting something on the front end, … Read more
This doesn’t seem especially complex, but does seem bulky and prone to errors. As I answered couple of times on similar issues – if this isn’t time critical then wait for WP 3.1 because it will have major improvements for querying by custom fields. See Advanced Metadata Queries for brief writeup on upcoming improvements. For … Read more
I think you can do a left join : left join $wpdb->postmeta my_field_meta on (p.ID = my_field_meta.post_id and my_field_meta.meta_key = ‘subscribe’) Where “subscribe” it’s the name of your custom field. So your code could be: $dayswithposts = $wpdb->get_results(“SELECT DISTINCT DAYOFMONTH(p.post_date) FROM $wpdb->posts as p LEFT JOIN $wpdb->postmeta my_field_meta on (p.ID = my_field_meta.post_id and my_field_meta.meta_key = … Read more
why not add a filed to user meta once they have voted and just check to see if that specific user can vote? add to your add vote function this lines: global $current_user; get_currentuserinfo(); add_user_meta( $current_user->ID , ‘voted’, true ); now if a user votes it saves a usermeta filed. then you can create a … Read more
Sorted this myself! May help some people… $cat = get_query_var(‘cat’); $prod_extras = get_option(Category_Extras); $this_application = $prod_extras[$cat][‘Category_Extras_Applications’]; if(!empty($this_application)) { echo $this_application; } Cheers, Dave
