我再次尝试组合一个页面模板，该模板将执行以下操作：
#1：以草稿形式提交产品 #2：向管理员发送电子邮件，请求批准（从草稿更改为发布） #3: 提交成功后，跳转至“我的账户”页面
所有字段都在那里，但 WP-admin 中的“产品”下没有显示任何产品。有人可以找出问题所在吗？
这是代码：
使用子主题的功能文件：
add_action( 'init', 'customer_creates_product_frontend' );
function customer_creates_product_frontend() {
if ( isset( $_POST['submit_product'] ) && wp_verify_nonce( $_POST['product_nonce'], 'submit_product_form' ) ) {
$errors = array();
$product_title = sanitize_text_field( $_POST['product_title'] );
if ( empty( $product_title ) ) {
$errors[] = 'The title of the product is mandatory.';
}
$product_condition = sanitize_text_field( $_POST['product_condition'] );
if ( empty( $product_condition ) ) {
$errors[] = 'The condition of the product is mandatory.';
}
$starting_price = sanitize_text_field( $_POST['starting_price'] );
if ( empty( $starting_price ) || ! is_numeric( $starting_price ) ) {
$errors[] = 'A valid starting price of the product is mandatory.';
}
$reservation_price = sanitize_text_field( $_POST['reservation_price'] );
if ( empty( $reservation_price ) || ! is_numeric( $reservation_price ) ) {
$errors[] = 'The reserveration price of the product is mandatory.';
}
$increment_price = sanitize_text_field( $_POST['increment_price'] );
if ( empty( $increment_price ) || ! is_numeric( $increment_price ) ) {
$errors[] = 'The increment of how much each bid should increase the product price with is mandatory.';
}
$starting_sale_date = sanitize_text_field( $_POST['starting_sale_date'] );
if ( empty( $starting_sale_date ) ) {
$errors[] = 'Starting date for the product is mandatory.';
}
$end_sale_date = sanitize_text_field( $_POST['end_sale_date'] );
if ( empty( $end_sale_date ) ) {
$errors[] = 'End date for the product is mandatory.';
}
$buy_now_price = sanitize_text_field( $_POST['buy_now_price'] );
if ( empty( $buy_now_price ) || ! is_numeric( $buy_now_price ) || $buy_now_price <= $starting_price) {
$errors[] = 'A valid BUY NOW price for the product is mandatory, and it must be higher than the starting price.';
}
$short_description = sanitize_text_field( $_POST['short_description'] );
if ( empty( $short_description ) ) {
$errors[] = 'The short description for the product is mandatory.';
}
$long_description = sanitize_text_field( $_POST['long_description'] );
if ( empty( $long_description ) ) {
$errors[] = 'The long description for the product is mandatory.';
}
if ( empty( $errors ) ) {
$new_product = wc_create_product( array (
'name' => $product_title,
'regular_price' => $starting_price,
'type' => 'auction', // set to "Auction" by the default - simple, grouped, externel, variable are also available
'description' => $short_description, // short desctiption
'short_description' => $long_description, // long description
'meta_input' => array (
'product_condition' => $product_condition,
'reservation_price' => $reservation_price,
'increment_price' => $increment_price,
'starting_sale_date' => date( 'Y-m-d \a\t H:i:s', strtotime( $starting_sale_date ) ),
'end_sale_date' => date( 'Y-m-d \a\t H:i:s', strtotime( $end_sale_date ) ),
'buy_now_price' => $buy_now_price,
)
)
);
if ( is_wp_error( $new_product ) ) {
echo '<p class="text-danger">Error creating product. Please try again.</p>';
} else {
$the_customer = wp_get_current_user();
$name_of_customer = $the_customer->get_billing_first_name();

$admin_email = get_option( 'admin_email' );

$message = 'The customer wants to publish '.$product_title.', with the following description: '.$short_description.'';
wp_mail( $admin_email, $subject, $message );
$new_product->set_status( 'draft' );
wp_safe_redirect( home_url( '/mitt-konto/' ) );
exit();
}
} else {
foreach ( $errors as $error ) {
echo '<p class="text-danger">' . $error . '</p>';
}
}
}
}

函数 wc_create_product() 不存在…从 WooCommerce 3 开始，您应该使用 CRUD 方法，如下所示（假设
WC_Product_Auctionadd_action( 'init', 'customer_creates_product_frontend' );
function customer_creates_product_frontend() {
$errors = array();

模板保持不变...
代码位于子主题的functions.php 文件中（或插件中）。应该可以。
