我創建了一個自定義插件，它可以在 woocommerce 單一產品頁面中動態顯示自定義字段。顯示字段，將其添加到購物車并添加到訂單數據和電子郵件。然而，我花了幾天時間嘗試添加文件上傳字段，但沒有成功。該字段在前端顯示如下：add_action( 'woocommerce_before_add_to_cart_button', 'display_custom_fields' );function display_custom_fields() {?> <p class="form-row validate-required" id="image" > <span class="woocommerce-input-wrapper"> <label for="image" class=""><?php echo $stamp_welcome_text; ?> </label> <input type="file" name="image" accept="image/*" > </span> </p><?php}然后添加到購物車，例如：add_filter( 'woocommerce_add_cart_item_data', 'add_cart_item_data', 10,3 );function add_cart_item_data( $cart_item_data, $product_id ) { if ($_FILES['image'] ) { require_once( ABSPATH . 'wp-admin/includes/image.php' ); require_once( ABSPATH . 'wp-admin/includes/file.php' ); require_once( ABSPATH . 'wp-admin/includes/media.php' ); $attachment_id = media_handle_upload( 'image', 0 ); if ( is_wp_error( $attachment_id ) AND $_FILES['image']['size'] > 0) { die($attachment_id->get_error_message().'. Παρακαλ? επικοινων?στε μαζ? μα?.'); } else $cart_item_data['image'] = $attachment_id; } return $item_cart_data;}當然，這只是代碼的一部分。其余字段工作完美。是的，如果有人想知道的話，我只嘗試過代碼本身。我已經“玩”了好幾天了，但我不知道出了什么問題。非常感謝任何幫助:)

您可以嘗試以下操作，將上傳的圖像數據存儲為自定義購物車項目數據并將其另存為自定義訂單項目元數據：
// Display additional product fields (+ jQuery code)
add_action( 'woocommerce_before_add_to_cart_button', 'display_additional_product_fields', 9 );
function display_additional_product_fields(){
?>
<p class="form-row validate-required" id="image" >
<label for="file_field"><?php echo __("Upload Image") . ': '; ?>
<input type='file' name='image' accept='image/*'>
</label>
</p>
<?php
}
// Add custom fields data as the cart item custom data
add_filter( 'woocommerce_add_cart_item_data', 'add_custom_fields_data_as_custom_cart_item_data', 10, 2 );
function add_custom_fields_data_as_custom_cart_item_data( $cart_item, $product_id ){
if( isset($_FILES['image']) && ! empty($_FILES['image']) ) {
$upload = wp_upload_bits( $_FILES['image']['name'], null, file_get_contents( $_FILES['image']['tmp_name'] ) );
$filetype = wp_check_filetype( basename( $upload['file'] ), null );
$upload_dir = wp_upload_dir();
$upl_base_url = is_ssl() ? str_replace('http://', 'https://', $upload_dir['baseurl']) : $upload_dir['baseurl'];
$base_name = basename( $upload['file'] );
$cart_item['file_upload'] = array(
'guid' => $upl_base_url .'/'. _wp_relative_upload_path( $upload['file'] ), // Url
'file_type' => $filetype['type'], // File type
'file_name' => $base_name, // File name
'title' => ucfirst( preg_replace('/\.[^.]+$/', '', $base_name ) ), // Title
);
$cart_item['unique_key'] = md5( microtime().rand() ); // Avoid merging items
}
return $cart_item;
}
// Display custom cart item data in cart (optional)
add_filter( 'woocommerce_get_item_data', 'display_custom_item_data', 10, 2 );
function display_custom_item_data( $cart_item_data, $cart_item ) {
if ( isset( $cart_item['file_upload']['title'] ) ){
$cart_item_data[] = array(
'name' => __( 'Image uploaded', 'woocommerce' ),
'value' => str_pad($cart_item['file_upload']['title'], 16, 'X', STR_PAD_LEFT) . '…',
);
}
return $cart_item_data;
}
// Save Image data as order item meta data
add_action( 'woocommerce_checkout_create_order_line_item', 'custom_field_update_order_item_meta', 20, 4 );
function custom_field_update_order_item_meta( $item, $cart_item_key, $values, $order ) {
if ( isset( $values['file_upload'] ) ){
$item->update_meta_data( '_img_file', $values['file_upload'] );
}
}
// Admin orders: Display a linked button + the link of the image file
add_action( 'woocommerce_after_order_itemmeta', 'backend_image_link_after_order_itemmeta', 10, 3 );
function backend_image_link_after_order_itemmeta( $item_id, $item, $product ) {
// Only in backend for order line items (avoiding errors)
if( is_admin() && $item->is_type('line_item') && $file_data = $item->get_meta( '_img_file' ) ){
echo '<p><a href="'.$file_data['guid'].'" target="_blank" class="button">'.__("Open Image") . '</a></p>'; // Optional
echo '<p><code>'.$file_data['guid'].'</code></p>'; // Optional
}
}
// Admin new order email: Display a linked button + the link of the image file
add_action( 'woocommerce_email_after_order_table', 'wc_email_new_order_custom_meta_data', 10, 4);
function wc_email_new_order_custom_meta_data( $order, $sent_to_admin, $plain_text, $email ){
// On "new order" email notifications
if ( 'new_order' === $email->id ) {
foreach ($order->get_items() as $item ) {
if ( $file_data = $item->get_meta( '_img_file' ) ) {
echo '<p>
<a href="'.$file_data['guid'].'" target="_blank" class="button">'.__("Download Image") . '</a><br>
<pre><code style="font-size:12px; background-color:#eee; padding:5px;">'.$file_data['guid'].'</code></pre>
</p><br>';
}
}
}
}
此代碼位于活動子主題（或活動主題）的functions.php 文件中。
在 Woocommerce 版本 4.3.x 中進行了測試，并使用所有類型的默認 WooCommerce 產品。

您可以使用 Product Addons 等插件來完成此操作
https://woocommerce.com/products/product-add-ons/
這是文檔的鏈接，專門解釋了允許文件上傳（它們可以是免費的，也可以按上傳收費）
https://docs.woocommerce.com/document/product-add-ons/#section-9
希望這可以幫助！
