There is three way to use function.php file variable into plugin file. Using global. Make sure you globalize it first. global $my_variable; echo $my_variable; I recommend is using WordPress built-in filter mechanism add_filter. You add the filter in your functions.php file and apply it where needed. In functions.php: add_filter( ‘my_variable’, ‘return_my_variable’ ); function return_my_variable( $arg … Read more
To preserve pagination, try: <?php $authors = get_users( array( ‘fields’ => ‘ID’, ‘role’ => ‘author’ ) ); $authors = implode(‘,’, $authors); ?> <?php if ( bp_has_members( bp_ajax_querystring( ‘members’ ). ‘&per_page=25&include=” . $authors) ) : ?> //etc
loop_start should be a good option. loop_start executes before the loop displays the first post EXAMPLE: add_action( ‘loop_start’, function ( $q ) { if ( $q->is_main_query() // Do this only for the main query && $q->is_category() // Only target category pages ) { // Add your code here } });
Yes, a plugin that does not properly clean up after itself can continue to affect your site even after deletion. It can leave stuff behind in the database, or make alterations to your .htaccess file, which is probably the case in your scenario. You might need to restore your .htaccess file – look here for … Read more
Yes it is possible, but there isn’t much point in that. The crudest way is to use a filter on the result of getting the ‘rewrite_rules’ option, and manipulating it by adding the entries you require directly to the array, and then you might need to filter those rules out when the option is updated. … Read more
Completely possible. Say you have domain.com. You set up a WordPress installation in domain.com/my-special-page, and you will be able to access your WordPress site there. You can ALSO set it up at domain.com/my-special-page.php if you really want to keep file name extensions, but it’s more work, and an uglier URL, so I wouldn’t recommend.
There’s no built-in functionality to append meta values you’ll need to do it manually. If you plan on adding multiple values I would suggest saving it as an array but it will serialize it in the database which will make it harder to run WP_Meta_Query on. $user_id = fav_authors_get_user_id(); $fav_author_id = 2; $author_list = get_user_meta( … Read more
I don’t know what your “system” as a whole is intended to look like but the function you want is wp_update_plugins() in wp-includes/update.php.
As mentioned in the comments, you can use the Plugin and Metadata APIs to attach some functionality to the ‘profile_update’ action such that whenever a user’s profile information receives an update, custom user-metadata is set to the time of the update: function wpse216609_update_profile_modified( $user_id ) { update_user_meta( $user_id, ‘wpse216609_profile_updated’, current_time( ‘mysql’ ) ); } add_action( … Read more
I figured out the answer, so I thought I’d post it. My code looks like this now and it works: add_action( ‘processed_subscription_payment’, ‘updatedays’, 10, 2 ); function updatedays($user_id, $subscription_key) { //do what I need to the sub key } There really needs to be more examples on the Woothemes documentation though..
