php - 在 Woocommerce 3 中使用 CRUD 方法以编程方式创建产品

Question

我想使用 PHP 代码以编程方式创建一个新的 Woocommerce 产品，并且我已经尝试使用 Woocommerce 3 CRUD 方法:

//Woocommerce CRUD
$objProduct = new WC_Product_Simple();

$objProduct->set_name('My Product 1'); //Set product name.
$objProduct->set_status('publish'); //Set product status.
//$objProduct->set_featured(FALSE); //Set if the product is featured.                          | bool
$objProduct->set_catalog_visibility('visible'); //Set catalog visibility.                   | string $visibility Options: 'hidden', 'visible', 'search' and 'catalog'.
$objProduct->set_description('My custom long description'); //Set product description.
//$objProduct->set_short_description('My short description'); //Set product short description.
//$objProduct->set_sku('U-123'); //Set SKU

$objProduct->set_price(5.00); //Set the product's active price.
//$objProduct->set_regular_price(5.00); //Set the product's regular price.
//$objProduct->set_sale_price(); //Set the product's sale price.
//$objProduct->set_date_on_sale_from(); //Set date on sale from.                              | string|integer|null $date UTC timestamp, or ISO 8601 DateTime. If the DateTime string has no timezone or offset, WordPress site timezone will be assumed. Null if their is no date.
//$objProduct->set_date_on_sale_to();//Set date on sale to.                                   | string|integer|null $date UTC timestamp, or ISO 8601 DateTime. If the DateTime string has no timezone or offset, WordPress site timezone will be assumed. Null if their is no date.

//$objProduct->set_manage_stock(TRUE); //Set if product manage stock.                         | bool
//$objProduct->set_stock_quantity(10); //Set number of items available for sale.
//$objProduct->set_stock_status('instock'); //Set stock status.                               | string $status 'instock', 'outofstock' and 'onbackorder'
//$objProduct->set_backorders('no'); //Set backorders.                                        | string $backorders Options: 'yes', 'no' or 'notify'.
//$objProduct->set_sold_individually(FALSE); //Set if should be sold individually.            | bool

//$objProduct->set_weight(); //Set the product's weight.
//$objProduct->set_length(); //Set the product length.
//$objProduct->set_width(); //Set the product width.
//$objProduct->set_height(); //Set the product height.

//$objProduct->set_upsell_ids($upsell_ids); //Set upsell IDs.                               | array $upsell_ids IDs from the up-sell products.
//$objProduct->set_cross_sell_ids($cross_sell_ids); //Set crosssell IDs.                    | array $cross_sell_ids IDs from the cross-sell products.

$objProduct->set_reviews_allowed(TRUE); //Set if reviews is allowed.                        | bool

//$objProduct->set_purchase_note($purchase_note); //Set purchase note.                      | string $purchase_note Purchase note.


$attribute = new WC_Product_Attribute();
$attribute->set_id(wc_attribute_taxonomy_id_by_name('pa_color')); //if passing the attribute name to get the ID
$attribute->set_name('pa_color'); //attribute name
$attribute->set_options('red'); // attribute value
$attribute->set_position(1); //attribute display order
$attribute->set_visible(1); //attribute visiblity
$attribute->set_variation(0);//to use this attribute as varint or not

$raw_attributes[] = $attribute; //<--- storing the attribute in an array

$attribute = new WC_Product_Attribute();
$attribute->set_id(25);
$attribute->set_name('pa_size');
$attribute->set_options('XL');
$attribute->set_position(2);
$attribute->set_visible(1);
$attribute->set_variation(0);

$raw_attributes[] = $attribute; //<--- storing the attribute in an array

$objProduct->set_attributes($raw_attributes); //Set product attributes.                   | array $raw_attributes Array of WC_Product_Attribute objects.

//$objProduct->set_category_ids($term_ids); //Set the product categories.                   | array $term_ids List of terms IDs.
//$objProduct->set_tag_ids($term_ids); //Set the product tags.                              | array $term_ids List of terms IDs.

//$objProduct->set_image_id(); //Set main image ID.                                         | int|string $image_id Product image id.
//$objProduct->set_gallery_image_ids(); //Set gallery attachment ids.                       | array $image_ids List of image ids.

$new_product_id = $objProduct->save(); //Saving the data to create new product, it will return product ID.

return;
}

但我收到此错误:

22-Oct-2018 20:25:19 UTC] PHP Fatal error: Uncaught Error: Class 'WC_Product_Simple' not found in /home/u1771p590/domains/famyfuerza.com/public_html/store/wp-content/plugins/ff-dropship-data-scraper/ff-dropship-data-scraper.php:165 Stack trace:

我试图包含简单的产品类，但这产生了另一个错误，表明缺少另一个类。

有人知道如何解决这个问题吗？或者有另一种通过代码创建woocommerce产品的方法？

Answer 1

您没有访问 WC_Product_simple来自您自定义的实例对象 Dropship Data Scraper插入。
有罪的可能主要是两件事:

您尚未安装 Woocommerce。

插件 Dropship 数据抓取工具 已过时，需要更改，以处理 woocommerce。

Try to include the global Woocommerce object and to enable Woocommerce support in your plugin.

使用 CRUD methods introduced in Woocommerce 3 以编程方式创建产品这是使其工作的正确方法。

If you need to handle product attributes creation or product variations creation, refer to:

• Create new product attribute programmatically in Woocommerce
• Create programmatically a WooCommerce product variation with new attribute values
• Create programmatically a variable product and two new attributes in WooCommerce

所有产品属性及其术语值 需要在之前创建.产品类别和产品标签也是如此。
1) 代码功能:

// Custom function for product creation (For Woocommerce 3+ only)
function create_product( $args ){

    if( ! function_exists('wc_get_product_object_type') && ! function_exists('wc_prepare_product_attributes') )
        return false;

    // Get an empty instance of the product object (defining it's type)
    $product = wc_get_product_object_type( $args['type'] );
    if( ! $product )
        return false;

    $product->set_name( $args['name'] ); // Name (title).
    if( isset( $args['slug'] ) )

    // Description and short description:
    $product->set_description( $args['description'] );
    $product->set_short_description( $args['short_description'] );

    // Status ('publish', 'pending', 'draft' or 'trash')
    $product->set_status( isset($args['status']) ? $args['status'] : 'publish' );

    // Visibility ('hidden', 'visible', 'search' or 'catalog')
    $product->set_catalog_visibility( isset($args['visibility']) ? $args['visibility'] : 'visible' );

    // Featured (boolean)

        }
    }

    // Sold Individually

    // Weight, dimensions and shipping class

    if( isset( $args['tag_ids'] ) )
        $product->set_tag_ids( $args['tag_ids'] );


    // Images and Gallery
    $product->set_image_id( isset( $args['image_id'] ) ? $args['image_id'] : "" );
    $product->set_gallery_image_ids( isset( $args['gallery_ids'] ) ? $args['gallery_ids'] : array() );

    ## --- SAVE PRODUCT --- ##
    $product_id = $product->save();

    return $product_id;
}

// Utility function that returns the correct product object instance
function wc_get_product_object_type( $type ) {
    // Get an instance of the WC_Product object (depending on his type)

    } elseif( isset($args['type']) && $args['type'] === 'external' ){
        $product = new WC_Product_External();
    } else {
        $product = new WC_Product_Simple(); // "simple" By default
    } 
    
    if( ! is_a( $product, 'WC_Product' ) )
        return false;
    else
        return $product;
}

// Utility function that prepare product attributes before saving
function wc_prepare_product_attributes( $attributes ){
    global $woocommerce;

    $data = array();
    $position = 0;

    foreach( $attributes as $taxonomy => $values ){
        if( ! taxonomy_exists( $taxonomy ) )
            continue;

        // Get an instance of the WC_Product_Attribute Object
        $attribute = new WC_Product_Attribute();

        $term_ids = array();

        // Loop through the term names
        foreach( $values['term_names'] as $term_name ){
            if( term_exists( $term_name, $taxonomy ) )
                // Get and set the term ID in the array from the term name
                $term_ids[] = get_term_by( 'name', $term_name, $taxonomy )->term_id;
            else
                continue;
        }

        $taxonomy_id = wc_attribute_taxonomy_id_by_name( $taxonomy ); // Get taxonomy ID

        $attribute->set_id( $taxonomy_id );
        $attribute->set_name( $taxonomy );
        $attribute->set_options( $term_ids );
        $attribute->set_position( $position );
        $attribute->set_visible( $values['is_visible'] );
        $attribute->set_variation( $values['for_variation'] );

        $data[$taxonomy] = $attribute; // Set in an array

        $position++; // Increase position
    }
    return $data;
}

2) 用法: - 具有 2 个产品属性“颜色”和“尺寸”的简单产品创建示例:

$product_id = create_product( array(
    'type'               => '', // Simple product by default
    'name'               => __("The product title", "woocommerce"),
    'description'        => __("The product description…", "woocommerce"),
    'short_description'  => __("The product short description…", "woocommerce"),
    // 'sku'                => '',
    'regular_price'      => '5.00', // product price
    // 'sale_price'         => '',
    'reviews_allowed'    => true,
    'attributes'         => array(
        // Taxonomy and term name values
        'pa_color' => array(
            'term_names' => array('Red', 'Blue'),
            'is_visible' => true,
            'for_variation' => false,
        ),
        'pa_size' =>  array(
            'term_names' => array('X Large'),
            'is_visible' => true,
            'for_variation' => false,
        ),
    ),
) );  

// Displaying the created product ID
echo $product_id;

仅使用 Woocommerce 3 CRUD 方法进行测试和工作。
