我通过feed以编程方式导入产品，如下所示：

$request = wp_remote_get(\'myapiurl\');
$response = wp_remote_retrieve_body( $request );

// decode the json

$json = json_decode($response, true);

// loop through the results

if( ! empty($json[ \'results\' ])) {
    foreach($json[ \'results\' ] as $data) {

        // gather data you need, make sure to sanitize it

        $post_data = array(
              \'post_title\' => $data[ \'post_title\' ],
                \'post_name\' => $data[ \'post_name\' ],
                \'post_content\' => $data[ \'post_content\' ],
                \'post_category\' => $data[ \'post_category\' ],
                \'_price\' => $data[ \'price\' ],
                \'post_location\' => $data[ \'location\' ],
                \'post_stock\' => $data[ \'stock\' ],
                \'post_year\' => $data[ \'year\' ],
                \'post_images\' => $data[ \'images\' ],
                \'post_status\' => \'publish\',
                \'post_type\' => \'product\',
        );

        // create product or post and return the new ID

        $post_id = wp_insert_post($post_data, $wp_error);
    }
}

问题是图像没有作为特征图像插入。

请帮帮我
