SQL

found the solution <3 Used WHERE ‘$startday’ BETWEEN dstart AND dend plus : OR dstart >= ‘$startday’ SELECT * FROM wp_posts, wp_mec_dates AS mecd, wp_icl_translations WHERE wp_posts.ID = mecd.post_id and post_status=”publish” AND wp_icl_translations.language_code=”$lang” AND (‘$startday’ BETWEEN dstart AND dend OR dstart >= ‘$startday’) AND wp_posts.ID = wp_icl_translations.element_id ORDER BY dstart LIMIT 0,6

This is the solution I came up with: SELECT child_ID, posts.post_author, wp1.post_author FROM wp_posts posts LEFT JOIN ( SELECT MAX(ID) as child_ID, post_parent FROM wp_posts WHERE post_type=”ticket_reply” GROUP BY post_parent ) sl ON posts.ID = sl.post_parent INNER JOIN wp_posts wp1 on sl.child_ID = wp1.ID WHERE posts.ID = 1499

You can add the standard taxonomy joins to the query: global $wpdb; $cat_id = 79; // Whatever. $sql = ” select wp_posts.*, coalesce( ( select max(comment_date) from $wpdb->comments wpc where wpc.comment_post_id = wp_posts.id ), wp_posts.post_date ) as mcomment_date from $wpdb->posts wp_posts JOIN $wpdb->term_relationships AS tr ON wp_posts.ID = tr.object_id JOIN $wpdb->term_taxonomy AS tt ON tr.term_taxonomy_id …

If you can answer ‘yes’ to the questions in Emetrop’s comment, then try: $sql = $wpdb->get_results(‘SELECT * from table1 WHERE id = $bransId’);

I solve it. public function insertionRow($id){ global $wpdb; $wpdb->query(“INSERT INTO wp_choix_attributs_liste (att_id) VALUES (“.$id.”);”); } In my html with the checkbox. if(isset($_POST[‘sub’])) { foreach ($_POST[‘choixP’] as $id) { self::insertionRow($id); } }

I can’t simulate this on a clean install of WordPress. So probably there is some extra filtering of XSS/Injection prevention happening on the server side. You should probably check that out first.

Thanks Milo for the answer! This block of code selects posts that have two categories at the same time. ( ( SELECT COUNT(1) FROM wp_term_relationships WHERE term_taxonomy_id IN (35,33) AND object_id = wp_posts.ID ) = 2 ) Where 35,33 are categories IDs and 2 – number of categories.
