我正在为客户端创建自定义CSV导入程序并添加图片,但是缩略图未正确生成.使用像Regenerate Thumbnails这样的插件后,它们会正确显示.

这是我添加附件并将其链接到帖子的代码.

$uploadDir = 'wp-content/uploads/importedproductimages/';
    $siteurl = get_option('siteurl');
    $thumbnail = 'importedproductimages/' . $name;
    $filename = 'importedproductimages/' . $name;
    $wp_filetype = wp_check_filetype($filename,null);
    $attachment = array(
                'post_author' => 1,'post_date' => current_time('mysql'),'post_date_gmt' => current_time('mysql'),'post_mime_type' => $wp_filetype['type'],'post_title' => $filename,'comment_status' => 'closed','ping_status' => 'closed','post_content' => '','post_status' => 'inherit','post_modified' => current_time('mysql'),'post_modified_gmt' => current_time('mysql'),'post_parent' => $post_id,'post_type' => 'attachment','guid' => $siteurl.'/'.$uploadDir.$name
    );

    $attach_id = wp_insert_attachment( $attachment,$filename,$post_id );
    $attach_data = wp_generate_attachment_metadata( $attach_id,$thumbnail );
    wp_update_attachment_metadata( $attach_id,$attach_data );

    // add featured image to post
    add_post_meta($post_id,'_thumbnail_id',$attach_id);

为什么缩略图没有正确生成？
先感谢您.

编辑：

我也像image.php一样包括：

require_once(ABSPATH . 'wp-admin/includes/image.php');

解决方法

这最终为我工作：

function createnewproduct($product)
        {


            $new_post = array(
                'post_title' => $product['Product'],'post_content' => $product['Long_description'],'post_status' => 'publish','post_type' => 'product'
            );

            $skuu = $product['SKU'];
            $post_id = wp_insert_post($new_post);
            update_post_meta($post_id,'_sku',$skuu );
            update_post_meta( $post_id,'_regular_price',$product['ourPrice'] );
            update_post_meta( $post_id,'_manage_stock',true );
            update_post_meta( $post_id,'_stock',$product['Qty'] );
            update_post_meta( $post_id,'_weight',$product['Weight'] );
            if (((int)$product['Qty']) > 0) {
                update_post_meta( $post_id,'_stock_status','instock');
            }


            $dir = dirname(__FILE__);
            $imageFolder = $dir.'/../import/';
            $imageFile   = $product['ID'].'.jpg';
            $imageFull = $imageFolder.$imageFile;

            // only need these if performing outside of admin environment
            require_once(ABSPATH . 'wp-admin/includes/media.php');
            require_once(ABSPATH . 'wp-admin/includes/file.php');
            require_once(ABSPATH . 'wp-admin/includes/image.php');

            // example image
            $image = 'http://localhost/wordpress/wp-content/import/'.$product['ID'].'.jpg';

            // magic sideload image returns an HTML image,not an ID
            $media = media_sideload_image($image,$post_id);

            // therefore we must find it so we can set it as featured ID
            if(!empty($media) && !is_wp_error($media)){
                $args = array(
                    'post_type' => 'attachment','posts_per_page' => -1,'post_status' => 'any','post_parent' => $post_id
                );

                // reference new image to set as featured
                $attachments = get_posts($args);

                if(isset($attachments) && is_array($attachments)){
                    foreach($attachments as $attachment){
                        // grab source of full size images (so no 300x150 nonsense in path)
                        $image = wp_get_attachment_image_src($attachment->ID,'full');
                        // determine if in the $media image we created,the string of the URL exists
                        if(strpos($media,$image[0]) !== false){
                            // if so,we found our image. set it as thumbnail
                            set_post_thumbnail($post_id,$attachment->ID);
                            // only want one image
                            break;
                        }
                    }
                }
            }
        }
