Comment afficher un champ personnalisé dans les commandes woocommerce dans le panneau d'administration?

Le code que vous avezfourniestincomplet. Jene saispas si c'est le seul code que vous utilisezpour réaliser ce que vous voulez. Donc,en plus dupremierbloc de code que vous avezfourni,ci-dessous,j'ajoutetout le reste du code quiestnécessairepour afficher lenouveau champ sur lebackend dans la zone `` Détails de la commande ''et le rendremodifiable via des champspersonnalisés. Veuilleznoter que dans votre deuxièmebloc de code,vous aveznommé la clé de champ comme _billing_new_phone. Toutnom de clé de champpersonnalisé commençantpar _ (trait de soulignement)est un champpersonnalisémasqué & amp;n'apparaîtrapas sur lebackend sous "Champspersonnalisés".

 /**
 * Process the checkout
 */
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
    // Check if set, if its not set add an error.
    if ( ! $_POST['billing_phone_new'] )
        wc_add_notice( __( 'Phone 2 is compulsory. Please enter a value' ), 'error' );
}


/**
 * Update the order meta with field value
 */
add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );

function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ( ! empty( $_POST['billing_phone_new'] ) ) {
        update_post_meta( $order_id, 'billing_phone_new', sanitize_text_field( $_POST['billing_phone_new'] ) );
    }
}


/**
 * Display field value on the order edit page
 */
add_action( 'woocommerce_admin_order_data_after_billing_address', 'my_custom_checkout_field_display_admin_order_meta', 10, 1 );

function my_custom_checkout_field_display_admin_order_meta($order){
    echo '<p><strong>'.__('Phone 2').':</strong> <br/>' . get_post_meta( $order->get_id(), 'billing_phone_new', true ) . '</p>';
}
 

WooCommercene rendpas lenouveau champ depaiementmodifiable dans saboîte standard "Détails de la commande". Il sera disponibleen mode `` affichage uniquement '' dans cetteboîte,mais vouspouvez lemodifier via lebloc de champspersonnalisés standard de WordPress. Voir la capture d'écran ci-dessous.

The code you have provided is incomplete. Not sure if that is the only code you are using to achieve what you want. So, besides first code block which you have provided, bellow I am adding all rest of the code which is required to show the new field on backend in 'Order Details' box and make it editable through custom fields. Please note, in your second code block you have named the field key as _billing_new_phone. Any custom field key name which starts with _ (underscore) is a hidden custom field & won't show up on backend under "Custom Fields".

/**
 * Process the checkout
 */
add_action('woocommerce_checkout_process', 'my_custom_checkout_field_process');

function my_custom_checkout_field_process() {
    // Check if set, if its not set add an error.
    if ( ! $_POST['billing_phone_new'] )
        wc_add_notice( __( 'Phone 2 is compulsory. Please enter a value' ), 'error' );
}


/**
 * Update the order meta with field value
 */
add_action( 'woocommerce_checkout_update_order_meta', 'my_custom_checkout_field_update_order_meta' );

function my_custom_checkout_field_update_order_meta( $order_id ) {
    if ( ! empty( $_POST['billing_phone_new'] ) ) {
        update_post_meta( $order_id, 'billing_phone_new', sanitize_text_field( $_POST['billing_phone_new'] ) );
    }
}


/**
 * Display field value on the order edit page
 */
add_action( 'woocommerce_admin_order_data_after_billing_address', 'my_custom_checkout_field_display_admin_order_meta', 10, 1 );

function my_custom_checkout_field_display_admin_order_meta($order){
    echo '<p><strong>'.__('Phone 2').':</strong> <br/>' . get_post_meta( $order->get_id(), 'billing_phone_new', true ) . '</p>';
}

WooCommerce does not make the new checkout field editable under its standard 'Order Details' box. It will be available as 'view only' mode in that box but you can edit the same through WordPress' standard custom fields block. See below screenshot.

Voici la solution: L'accès direct aux donnéesproduitn'estpas autorisé,parex.

 $product->id
 

Laméthode correctepour l'avenirest:

 $product->get_id()
 

Here is the solution : Accessing directly product data is not allowed, e.g.

$product->id

The correct method going forward is:

$product->get_id()
