 $reponse = $bdd->query("SELECT  a.post_title, m1.meta_value AS total, m2.meta_value AS titre, m3.meta_value AS date
FROM  wp_posts a
LEFT JOIN wp_postmeta m1
    ON a.ID = m1.post_id
LEFT JOIN wp_postmeta m2
    ON a.ID = m2.post_id
LEFT JOIN wp_postmeta m3
    ON a.ID = m3.post_id
WHERE a.post_type=\'post\' 
AND m1.meta_key=\'total_des_prises\'
AND m2.meta_key=\'titre\'
AND m3.meta_key=\'date\';
 " );
