There was an error sorry :
function custom_order_by_acf_field_query($query) {
if (!is_admin() && isset($query->query_vars['orderby'])) {
// Récupérer le champ ACF entre {{}}
$orderby_field = str_replace(array('{{', '}}'), '', $query->query_vars['orderby']);
if ( $orderby_field != $query->query_vars['orderby']) {
$query->set('meta_key', $orderby_field);
$query->set('orderby', 'meta_value_num');
}
}
}
Here is a code that I improved, perfectly generic that everyone can use.
Just put in the order field of your component, the acf field enters {{}} and it will sort in the correct order.
function custom_order_by_acf_field_query($query) {
if (!is_admin()) {
if (isset($query->query_vars['orderby'])) {
// Récupérer le champ ACF entre {{}}
$orderby_field = str_replace(array('{{', '}}'), '', $query->query_vars['orderby']);
if (is_string($orderby_field)) {
// Concaténer avec le préfixe "_" pour former la clé de méta ACF
$meta_key = '_'.$orderby_field;
// Vérifier si le champ ACF est spécifié dans la requête
if (metadata_exists('post', $query->get('post_type'), $meta_key)) {
$query->set('meta_key', $meta_key);
$query->set('orderby', 'meta_value_num');
// $query->set('order', 'DESC'); // Vous pouvez définir l'ordre ici si nécessaire
}
}
}
}
}
add_action('pre_get_posts', 'custom_order_by_acf_field_query');
With a lot of research and testing, I believe that it is indeed impossible to do so with an ACF field. you must therefore modify it via a function in functions.php that I wrote and that I share with you
function custom_order_by_acf_field_query($query) {
if ( !is_admin()) {
if(isset($query->query_vars['orderby']) && $query->query_vars['orderby'] == '{{coefficient}}') {
$query->set('meta_key', 'coefficient');
$query->set('orderby', 'meta_value_num');
$query->set('order', 'DESC');
}
}
}
add_action('pre_get_posts', 'custom_order_by_acf_field_query');
