Option 1 – save a backup of site_url and home_url If you want to detect whenever the site_url or home_url changes (settings page, wp-config.php, functions.php,…) the only way to get it would be to save some extra options on the database with those urls so that whenever the site is opened you would check if … Read more
If you want your plugin being hosted on WordPress.org Plugin Repository, you cannot combine Free and Premium version, in one plugin. You have to maintain two versions, Lite, hosted on WordPress.org, and Premium, hosted on your website. Plugins hosted on WordPress.org cannot make any remote requests to your website ( aka “calling home” ), therefore, … Read more
Helper function Here’s a helper function (untested) to check if a given user ID is the first commenter for a given post ID: /** * Check if a given user ID is the first commenter for a given post ID * * @param int $user_id User ID * @param int $post_id Post ID * @return … Read more
As described in the documentation, you have call this inside a hook. For wordpress versions < 3.4: use the init or any subsequent action to call this function. Calling it outside of an action can lead to troubles. See #14024 for details. Example: add_action(‘init’, ‘get_user_email’); function get_user_email() { $logged_in_user = wp_get_current_user(); if($logged_in_user->ID != 0){ $email … Read more
After turning on WP_DEBUG, define(‘WP_DEBUG’, true); I was receiving the error: Conditional query tags do not work before the query is run. Before then, they always return false. After googling that error, I found a solution that works: add_action( ‘template_redirect’, ‘check_for_frontpage’ ); function check_for_frontpage() { if ( is_front_page() || is_home() ) { echo “<script>console.log( ‘Debug … Read more
You don’t, or at least not in the way you expect. If the code in the question worked as expected, it would still be committing a mortal performance sin, database writes on the frontend. So lets take the relevant code: $cat_id = $_GET[‘tag_ID’]; if (metadata_exists(‘term’, $cat_id, ‘cat_settings’ )) { $catSettings = get_term_meta($cat_id, ‘cat_settings’, false); } … Read more
In your options page each field should be put into an options array. For Example: When you registered your settings page you should have used a code like this: register_setting( ‘pluginPage’, ‘rt_fed_settings’, ‘rt_validate’); Once on your page where you want to call settings, use this code: $options_fed = get_option(‘rt_fed_settings’); // this is calling your settings … Read more
At the time of registering taxonomy, make sure you use the show_in_nav_menus parameter and set it true. For Example: $args = array( ‘label’ => __( ‘book’, ‘textdomain’ ), ‘public’ => true, ‘rewrite’ => array(‘slug’ => ‘book’, ‘with_front’ => true), ‘hierarchical’ => true, ‘show_in_nav_menus’ => true, ‘show_ui’ => true, ); register_taxonomy( ‘book’, ‘products’, $args);
No, it just means it’s used by many plugins, not that Core includes it. Many of the functions in that library seem to use the JsonLdProcessor class that is also in that library, I’d check for that before including: if ( ! class_exists( ‘JsonLdProcessor’ ) ) { require_once( ‘jsonld.php’ ) }
Make sure you register the new post types before flushing! So call the function that registers them not only on init, but also in your activation/flush function. See very first example here: https://codex.wordpress.org/Function_Reference/flush_rewrite_rules.
