Vérifier si post existe

Comment puis-je vérifier si poste avec nom par exemple Météo existe? Sinon je veux le créer.

function such_post_exists($title) {
global $wpdb;

$p_title = wp_unslash( sanitize_post_field( 'post_title', $title, 0, 'db' ) );

if ( !empty ( $title ) ) {
    return (int) $wpdb->query("SELECT FROM $wpdb->posts WHERE post_title = $p_title");
}

return 0;
}

Wordpress a une fonction post_exists qui renvoie l'identifiant de publication ou 0 sinon. Donc tu peux faire

if ( 0 === post_exists( $title ) ) {
    **YOUR_CODE_HERE**
}
