WooCommerce单品添加图片文件上传字段

Question

我创建了一个自定义插件，它在 woocommerce 单个产品页面中动态显示自定义字段。显示字段，将其添加到购物车并添加到订单数据和电子邮件中。但是，我已经尝试了几天来添加一个没有运气的文件上传字段。该字段在前端显示如下：

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
}

然后像这样添加到购物车：

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().'. Παρακαλώ επικοινωνήστε μαζί μας.');
        } else $cart_item_data['image'] = $attachment_id;
    }
    return $item_cart_data;
}

当然，这只是一部分，code.The 其余字段都运行良好。是的，如果有人想知道的话，我只是自己尝试了代码。

我已经“玩”了好几天了，但我不知道哪里出了问题。非常感谢任何帮助:)

Answer 1

您可以使用 Product Addons 等插件来完成此操作

https://woocommerce.com/products/product-add-ons/

这里有一个 link 文档，专门解释了允许文件上传（它们可以免费或每次上传收费）

https://docs.woocommerce.com/document/product-add-ons/#section-9

希望对您有所帮助！

您可以尝试以下方法，它将上传的图像数据存储为自定义购物车项目数据并将其保存为自定义订单项目元数据：

// 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>';
            }
        }
    }
}

此代码位于您的活动子主题（或活动主题）的 functions.php 文件中。

在 Woocommerce 版本 4 中测试。3.x 并使用所有类型的默认 WooCommerce 产品。

我发现与我的模板 (woodmart) 有冲突该代码在 twentytwenty 和 storefront

上完美运行

我应该早点想到这一点，而不是一个星期把头撞在墙上。

多张图片，如果有人需要的话。
