【问题标题】:Woocommerce Programmatically Add Product Attributes and their corresponding valuesWoocommerce 以编程方式添加产品属性及其对应值
【发布时间】:2020-03-15 10:50:03
【问题描述】:

我正在构建一个获取产品的脚本,但我被困在以编程方式添加属性的部分。所以基本上我想检查一个属性是否存在,如果不添加它。然后检查它的价值是否存在,如果不存在,则添加它的价值,并将所有内容附加到我的产品中。

这是我得到产品的格式:

 [attributes] => Array
(
[0] => stdClass Object
    (
        [id] => 332
        [name] => Gender
        [value] => Woman
    )

[1] => stdClass Object
    (
        [id] => 333
        [name] => Wheel Size
        [value] => 28 Inch
    )

[2] => stdClass Object
    (
        [id] => 334
        [name] => Frame height
        [value] => 56 cm
    )

现在我已经尝试了 2 个版本,我将粘贴两个代码示例。

版本 1:

foreach($product->attributes as $attribute) {
$slug = 'pa_' . strtolower($attribute->name);
$attribute_name = $attribute->name;
$attribute_value = $attribute->value;

$permalinks = get_option( 'woocommerce_permalinks' );

$taxonomy_data = array(
                    'hierarchical'          => true,
                    'update_count_callback' => '_update_post_term_count',
                    'labels'                => array(
                            'name'              => $attribute_name
                        ),
                    'show_ui'           => false,
                    'query_var'         => true,
                    'sort'              => false,
                    'public'            => true,
                    'show_in_nav_menus' => false,
                    'capabilities'      => array(
                        'manage_terms' => 'manage_product_terms',
                        'edit_terms'   => 'edit_product_terms',
                        'delete_terms' => 'delete_product_terms',
                        'assign_terms' => 'assign_product_terms',
                    )
                );

register_taxonomy( $slug, array('product'), $taxonomy_data );
// @end_Debug

}

这个版本只添加了以某种方式附加到产品的属性, 但它们在 Wordpress Admin 的“属性”选项卡下不可见。 我稍后会想要这些属性的过滤器,所以我需要 与 Woocommerce 属性的连接。


版本 2:

foreach($product->attributes as $attribute) {
$slug = 'pa_' . strtolower($attribute->name);
$attribute_name = $attribute->name;
$attribute_value = $attribute->value;
$table = $wpdb->prefix . 'woocommerce_attribute_taxonomies';

$attr = $wpdb->get_results( "SELECT * FROM {$table} WHERE attribute_name LIKE '%{$attribute_name}%'", OBJECT );
if(count($attr) > 0) {
    //
}
else {
    /** create taxonomy */
    $data = array(
        'attribute_label'   => $attribute_name,
        'attribute_name'    => $slug,
        'attribute_type'    => 'select',
        'attribute_orderby' => 'menu_order',
        'attribute_public'  => 0, // Enable archives ==> true (or 1)
    );

    $results = $wpdb->insert( "{$wpdb->prefix}woocommerce_attribute_taxonomies", $data );

    if ( is_wp_error( $results ) ) {
        return new WP_Error( 'cannot_create_attribute', $results->get_error_message(), array( 'status' => 400 ) );
    }

    $id = $wpdb->insert_id;

    do_action('woocommerce_attribute_added', $id, $data);

    wp_schedule_single_event( time(), 'woocommerce_flush_rewrite_rules' );
    /* end_Create */
}


// Clean attribute name to get the taxonomy
$taxonomy = 'pa_' . wc_sanitize_taxonomy_name( $attribute_name );

$option_term_ids = array(); // Initializing

// Loop through defined attribute data options (terms values)
if( term_exists( $attribute_value, $taxonomy ) ){
    // Save the possible option value for the attribute which will be used for variation later
    wp_set_object_terms( $product_id, $attribute_value, $taxonomy, true );
    // Get the term ID
    $option_term_ids[] = get_term_by( 'name', $attribute_value, $taxonomy )->term_id;
}

    // Loop through defined attribute data
$attributes[$taxonomy] = array(
    'name'          => $taxonomy,
    'value'         => $option_term_ids, // Need to be term IDs
    'position'      => '1',
    'is_visible'    => '1',
    'is_variation'  => '1',
    'is_taxonomy'   => '1'
);

// Save the meta entry for product attributes
update_post_meta( $product_id, '_product_attributes', $attributes );

}

这似乎只是在产品属性选项卡下添加它们,也 不添加条款值。

    【解决方案1】:

    好的,这是一项相当复杂的任务,但这是我通过查看其他人的源代码并根据需要进行修改而得到的代码。

    首先,您将需要这些辅助函数。

    1. 要创建全局属性,您需要为每个属性(性别、车轮尺寸等)创建一个分类法,使用此函数:

      function create_global_attribute($name, $slug)
      {
      
          $taxonomy_name = wc_attribute_taxonomy_name( $slug );
      
          if (taxonomy_exists($taxonomy_name))
          {
              return wc_attribute_taxonomy_id_by_name($slug);
          }
      
          //logg("Creating a new Taxonomy! `".$taxonomy_name."` with name/label `".$name."` and slug `".$slug.'`');
      
          $attribute_id = wc_create_attribute( array(
              'name'         => $name,
              'slug'         => $slug,
              'type'         => 'select',
              'order_by'     => 'menu_order',
              'has_archives' => false,
          ) );
      
          //Register it as a wordpress taxonomy for just this session. Later on this will be loaded from the woocommerce taxonomy table.
          register_taxonomy(
              $taxonomy_name,
              apply_filters( 'woocommerce_taxonomy_objects_' . $taxonomy_name, array( 'product' ) ),
              apply_filters( 'woocommerce_taxonomy_args_' . $taxonomy_name, array(
                  'labels'       => array(
                      'name' => $name,
                  ),
                  'hierarchical' => true,
                  'show_ui'      => false,
                  'query_var'    => true,
                  'rewrite'      => false,
              ) )
          );
      
          //Clear caches
          delete_transient( 'wc_attribute_taxonomies' );
      
          return $attribute_id;
      }
      
    2. 现在要将这些应用于您的产品,我假设您正在使用每个都有变体的可变产品?父变量产品需要将其attribute 属性设置为特殊格式的属性数组。此函数创建该数组,并为每个属性创建全局分类(如果找不到)。

      //$rawDataAttributes must be in the form of array("Color"=>array("blue", "red"), "Size"=>array(12,13,14),... etc.)
      function generate_attributes_list_for_product($rawDataAttributes)
      {
          $attributes = array();
      
          $pos = 0;
      
          foreach ($rawDataAttributes as $name => $values)
          {
              if (empty($name) || empty($values)) continue;
      
              if (!is_array($values)) $values = array($values);
      
              $attribute = new WC_Product_Attribute();
              $attribute->set_id( 0 );
              $attribute->set_position($pos);
              $attribute->set_visible( true );
              $attribute->set_variation( true );
      
              $pos++;
      
              //Look for existing attribute:
              $existingTaxes = wc_get_attribute_taxonomies();
      
              //attribute_labels is in the format: array("slug" => "label / name")
              $attribute_labels = wp_list_pluck( $existingTaxes, 'attribute_label', 'attribute_name' );
              $slug = array_search( $name, $attribute_labels, true );
      
              if (!$slug)
              {
                  //Not found, so create it:
                  $slug = wc_sanitize_taxonomy_name($name);
                  $attribute_id = create_global_attribute($name, $slug);
              }
              else
              {
                  //Otherwise find it's ID
                  //Taxonomies are in the format: array("slug" => 12, "slug" => 14)
                  $taxonomies = wp_list_pluck($existingTaxes, 'attribute_id', 'attribute_name');
      
                  if (!isset($taxonomies[$slug]))
                  {
                      //logg("Could not get wc attribute ID for attribute ".$name. " (slug: ".$slug.") which should have existed!");
                      continue;
                  }
      
                  $attribute_id = (int)$taxonomies[$slug];
              }
      
              $taxonomy_name = wc_attribute_taxonomy_name($slug);
      
              $attribute->set_id( $attribute_id );
              $attribute->set_name( $taxonomy_name );
              $attribute->set_options($values);
      
              $attributes[] = $attribute;
          }
      
      
          return $attributes;
      }
      
    3. 我们几乎已准备好将属性应用于产品,但主要变量产品及其变体需要像任何 Wordpress 分类法一样为其分配分类术语。因此,如果您有一个名为“车轮尺寸”的分类法,其中包含术语“28 英寸”和“30 英寸”,那么父产品需要分配给它的所有“28 英寸”和“30 英寸”术语,以及变体需要为其分配单独的术语,因此一个为“28 英寸”,另一个为“30 英寸”。为了解决这个问题,我们使用此函数来获取和/或创建这些术语(如果它们不存在):

      function get_attribute_term($value, $taxonomy)
      {
          //Look if there is already a term for this attribute?
          $term = get_term_by('name', $value, $taxonomy);
      
          if (!$term)
          {
              //No, create new term.
              $term = wp_insert_term($value, $taxonomy);
              if (is_wp_error($term))
              {
                  //logg("Unable to create new attribute term for ".$value." in tax ".$taxonomy."! ".$term->get_error_message());
                  return array('id'=>false, 'slug'=>false);
              }
              $termId = $term['term_id'];
              $term_slug = get_term($termId, $taxonomy)->slug; // Get the term slug
          }
          else
          {
              //Yes, grab it's id and slug
              $termId = $term->term_id;
              $term_slug = $term->slug;
          }
      
          return array('id'=>$termId, 'slug'=>$term_slug);
      }
      

    好的,现在我们可以使用上面的方法将属性应用于我们的产品了。

    对于主变量产品:

    $yourRawAttributeList = array("Gender" => array("Woman", "Man"), "Wheel Size" => array("28 Inch","30 Inch","32 Inch"));
    $attribs = generate_attributes_list_for_product($yourRawAttributeList);
    
    $p = new WC_Product_Variable($postID);
    
    $p->set_props(array(
        'attributes'        => $attribs,
        //Set any other properties of the product here you want - price, name, etc.
    ));
    
    $postID = $p->save();
    
    if ($postID <= 0) return "Unable to create / update product!";
    
    //Attribute Terms: These need to be set otherwise the attributes dont show on the admin backend:
    foreach ($attribs as $attrib)
    {
        /** @var WC_Product_Attribute $attrib */
        $tax = $attrib->get_name();
        $vals = $attrib->get_options();
    
        $termsToAdd = array();
    
        if (is_array($vals) && count($vals) > 0)
        {
            foreach ($vals as $val)
            {
                //Get or create the term if it doesnt exist:
                $term = get_attribute_term($val, $tax);
    
                if ($term['id']) $termsToAdd[] = $term['id'];
            }
        }
    
        if (count($termsToAdd) > 0)
        {
            wp_set_object_terms($postID, $termsToAdd, $tax, true);
        }
    }
    

    对于该产品的每个变体:

        //This is an array of input attributes in the form: array("Color"=>"Navy", "Size"=>"25")
    $theseAttributes = array("Gender" => array("Woman"), "Wheel Size" => array("28 Inch"));
    
    //This is the final list of attributes that we are calculating below.
    $theseAttributesCalculated = array();
    
    //logg("Want to add these attributes to the variation: ".print_r($theseAttributes, true));
    
    $existingTax = wc_get_attribute_taxonomies();
    
    foreach ($theseAttributes as $name => $value)
    {
        if (strlen($name) == 0 || strlen($value) == 0)
        {
            //logg("Attribute array had a blank value for product variant ".$sku.': '.print_r($theseAttributes, true));
            return "Attribute array had a blank value.";
        }
    
        $tax = '';
        $slug = '';
    
        //Look for an existing taxonomy to match this attribute's $name
        //$thistax->attribute_name = slug of the taxonomy
        //$thistax->attribute_label = name of the taxonomy
    
        foreach ($existingTax as $thistax)
        {
            if ($thistax->attribute_label == $name)
            {
                $slug = $thistax->attribute_name;
                $tax = wc_attribute_taxonomy_name($slug);
                break;
            }
        }
    
        if (empty($tax))
        {
            $slug = wc_sanitize_taxonomy_name($name);
            //Taxonomy not found, so create it...
            if (create_global_attribute($name, $slug) > 0)
            {
                $tax = wc_attribute_taxonomy_name($slug);
            }
            else
            {
                //logg("Unable to create new attribute taxonomy ".$slug." for attribute ".$name."found in variable product ".$sku);
                continue;
            }
        }
    
    
        //logg("Want to add attribute ".$name. " value ".$value. " which is term ".$term_slug." (".$termId.") to post ".$parentID);
    
        $term = get_attribute_term($value, $tax);
    
    
        if ($term['id'])
        {
            // Set/save the attribute data in the product variation
            $theseAttributesCalculated[$tax] = $term['slug'];
        }
        else
        {
            //logg("Warning! Unable to create / get the attribute ".$value." in Taxonomy ".$tax);
        }
    }
    
    //logg("Finished gathering. Results: ".print_r($theseAttributesCalculated, true));
    
    
    $variation  = new \WC_Product_Variation($postID);
    
    $variation->set_props( array(
        'attributes'        => $theseAttributesCalculated,
    ));
    
    $postID = $variation->save();
    
    if ($postID <= 0) return "Unable to create product variation!";
