[英]Set Product sale price conditionally based on custom fields in Woocommerce
[英]WooCommerce product variation price based on custom fields
我有可變產品,我向其中添加了如下自定義字段:
function ab_preorder_variation_fields( $loop, $variation_data, $variation ) {
echo '<div class="options_group form-row form-row-full">';
// Is Preordable
woocommerce_wp_checkbox(
array(
'id' => '_ab_preorder_checkbox[' . $variation->ID . ']',
'wrapper_class' => 'show_if_simple',
'label' => __(' Disponible à la précommande', 'woocommerce' ),
'description' => __( 'Disponible à la précommande', 'woocommerce' ),
'desc_tip' => true,
'value' => get_post_meta( $variation->ID, '_ab_preorder_checkbox', true )
)
);
// Custom Preorder Price
woocommerce_wp_text_input(
array(
'id' => '_ab_preorder_custom_price[' . $variation->ID . ']',
'label' => __( 'Prix à la précommande', 'woocommerce' ),
'placeholder' => '',
'desc_tip' => true,
'description' => __( "Prix à la précommande", 'woocommerce' ),
'type' => 'number',
'custom_attributes' => array(
'step' => 'any',
'min' => '0'
),
'value' => get_post_meta( $variation->ID, '_ab_preorder_custom_price', true )
)
);
// Date de livraison estimée
woocommerce_wp_text_input(
array(
'id' => '_ab_preorder_estimated_date[' . $variation->ID . ']',
'label' => __( 'Date de livraison estimé', 'woocommerce' ),
'placeholder' => '24/09/2021',
'desc_tip' => true,
'description' => __( "Date de livraison estimé", "woocommerce" ),
'value' => get_post_meta( $variation->ID, '_ab_preorder_estimated_date', true )
)
);
echo '</div>';
}
add_action( 'woocommerce_product_after_variable_attributes', 'ab_preorder_variation_fields', 10, 3 ); // After all Variation fields
function ab_preorder_variation_fields_saving( $post_id ){
// Is Preordable
$woocommerce_text_field = $_POST['_ab_preorder_checkbox'][ $post_id ];
update_post_meta( $post_id, '_ab_preorder_checkbox', esc_attr( $woocommerce_text_field ) );
// Custom Preorder Price
$woocommerce_text_field = $_POST['_ab_preorder_custom_price'][ $post_id ];
update_post_meta( $post_id, '_ab_preorder_custom_price', esc_attr( $woocommerce_text_field ) );
// Date de livraison estimée
$woocommerce_text_field = $_POST['_ab_preorder_estimated_date'][ $post_id ];
update_post_meta( $post_id, '_ab_preorder_estimated_date', esc_attr( $woocommerce_text_field ) );
}
這是我想要做的:當客戶選擇變體時,我想:如果變體庫存數量為 0 並且選中了_ab_preorder_checkbox
復選框,我想將產品價格設置為 100。
我嘗試使用下面的代碼,但它不起作用:/
function action_woocommerce_before_calculate_totals( $cart_object) {
$cart_items = $cart_object->cart_contents;
if ( ! empty( $cart_items ) ) {
$price = 100;
foreach ( $cart_items as $key => $value ) {
if($value['data']['_ab_preorder_checkbox']=="yes")
$value['data']->set_price( $price );
}
}
};
add_action( 'woocommerce_before_calculate_totals', 'action_woocommerce_before_calculate_totals', 10, 2 );
誰能幫我解決這個問題?
問候,
由於 woocommerce 不允許購買零庫存產品,您需要為相關產品設置“允許延期交貨”選項。
我重新審視了你的代碼(特別是你的第二個函數)。
在您的情況下,鈎子woocommerce_before_calculate_totals
並不方便。 最好在產品上設置延期交貨自定義價格。
以下將在啟用復選框時設置變體的延期交貨價格,並將其顯示在相關變體上以及預計交貨日期:
// Admin Variation custom fields
add_action( 'woocommerce_product_after_variable_attributes', 'ab_preorder_variation_fields', 10, 3 );
