Afficher les valeurs de type de publication personnalisées en mode grille Wordpress
J'ai créé un type de message personnalisé dans WordPress, comme indiqué dans la figure.
Ce que je veux, c'est montrer les valeurs eneterd dans cette publication personnalisée dans la vue en grille du panneau d'administration. À présent, le panneau d'administration affiche uniquement les images du titre, de la date et du commentaire de l'article, mais je souhaite afficher les valeurs des champs Pair2, Acheter, Vendre et Activité telles qu'elles ont été entrées dans mon article personnalisé. J'ai cherché beaucoup mais je n'ai trouvé aucune solution. Comment dois-je m'y prendre dans WordPress?

Vous pouvez utiliser le filtre manage_edit-${post_type}_columns combiné à l'action manage_${post_type}_posts_custom_column. Vérifiez le exemple dans le Codex et déconstruisez-le étape par étape.
Assurez-vous d'abord de saisir le nom exact de votre type de message personnalisé enregistré. Vous avez enregistré le type de message avec le nom quote.
Ensuite, définissez les colonnes que vous souhaitez ajouter (voir set_custom_edit_quote_columns) et allouez les valeurs appropriées (voir custom_quote_columns).
Vous devriez vous retrouver avec quelque chose comme ça:
add_filter( 'manage_edit-quote_columns', 'set_custom_edit_quote_columns' );
add_action( 'manage_quote_posts_custom_column' , 'custom_quote_columns', 10, 2 );
function set_custom_edit_quote_columns( $columns ) {
$columns['pair'] = __( 'Pair' );
$columns['buysell'] = __( 'Buy Sell' );
$columns['activity'] = __( 'Activity' );
$columns['entryprice'] = __( 'Entry Price' );
$columns['stoploss'] = __( 'Stop Loss' );
$columns['takeprofit'] = __( 'Take Profit' );
return $columns;
}
function custom_quote_columns( $column, $post_id ) {
switch ( $column ) {
case 'pair' :
echo get_post_meta( $post_id, '_quote_post_pairname', true );
break;
case 'buysell' :
echo get_post_meta( $post_id, '_quote_post_buysell', true );
break;
case 'activity' :
echo get_post_meta( $post_id, '_quote_post_activity', true );
break;
case 'entryprice' :
echo get_post_meta( $post_id, '_quote_post_entryprice', true );
break;
case 'stoploss' :
echo get_post_meta( $post_id, '_quote_post_stoploss', true );
break;
case 'takeprofit' :
echo get_post_meta( $post_id, '_quote_post_takeprofit', true );
break;
}
}
