When viewing a single post, get_the_ID(); used within the loop will return the current post’s ID. But I don’t have a reference page that has the list of $query_vars params… Dumping it global $wp_query; var_dump($wp_query->query_vars); would provide such a reference. Where you’d subsequently see that $wp_query->query_vars[‘page_id’] yields the page ID.
No, and in fact you should not include the wp-admin/includes/upgrade.php file in a plugin. There is no real valid use case for doing so.

After researching this quite a bit I managed to sort the Events Manager events by date in the Essential Grid plugin.

When the wp_enqueue_scripts action fires, the main query has already run and the posts are in the global $wp_query. We just need to grab the ID from each object in $wp_query->posts, the wp_list_pluck function makes that easy: function wpd_get_post_ids(){ if( is_archive() ){ global $wp_query; $post_ids = wp_list_pluck( $wp_query->posts, ‘ID’ ); // $post_ids now contains an … Read more
No! WordPress will not protect against SQL injection in this case. You need to do so yourself, using $wpdb->esc_like and $wpdb->prepare: if ( isset( $_GET[‘q’] ) ) { // WordPress forces magic quotes (god knows why), unslash it $value = wp_unslash( ( string ) $_GET[‘q’] ); // Escape like wildcards so that MySQL interprets them … Read more
An easy query like the following should work for you: <?php $_query = new WP_Query( array( ‘post_type’ => ‘post’, ‘posts_per_page’ => -1, ‘post_status’ => ‘publish’, ‘meta_query’ => array( ‘relation’ => ‘OR’, array( ‘key’ => ‘key1’ ), array( ‘key’ => ‘key2’ ), ), ) ); ?> Note the ‘relation’=>’OR’ in meta_query.
