运行 WP All Import 后尝试自动更新 WPBakery 'Single Image' 图像 ID

Question

我正在尝试使用 WP All Export/Import 将 WordPress 安装的部分内容从实时站点传输到我的测试站点。 我不需要转移整个网站，只需转移带有某些自定义字段的某些页面/帖子即可进行测试。 WPBakery Page Builder 中的“单个图像”元素在导入后给我带来了麻烦。图像上传到测试站点后，图像 ID 保留 xml 文件中的值，而不是将图像 ID 更新为新的 ID 值。

这是一张显示正在发生的事情的图像。导入后，图像 ID 14821、14819、14820 等不会更新为新值。 图像 ID 未更新

每张图片都会正确上传到网站（使用新的图片 ID），但帖子中的图片 ID 不会更改。

这是 xml 数据的示例。 注意：[] 包围的值表示出于安全目的，信息已更改。

我不太擅长API编码，所以我尝试使用ChatGPT大约一个小时。 WP All Import 开发人员告诉我，这是自定义功能，他们不支持 WPBakery，因此他们建议使用 ChatGPT。我无法找到有效的解决方案。 这是我尝试的最后一段代码：

add_action('pmxi_gallery_image', 'update_image_ids_after_import', 10, 2);

function update_image_ids_after_import($image_url, $post_id) {
    // Fetch the XML data
    $xml_data = PMXI_Plugin::getInstance()->session->xml_data;

    // Get the content from the XML data
    $content = $xml_data['post']['Content'];

    // Extract image URLs from the content using regex
    preg_match_all('/vc_single_image image="(\d+)"/', $content, $matches);

    // Check if there are matches
    if (!empty($matches[1])) {
        // Loop through each matched image ID
        foreach ($matches[1] as $key => $old_image_id) {
            // Get the newly imported image ID
            $new_image_id = attachment_url_to_postid($image_url);

            // Replace the old image ID with the new one
            $content = str_replace('vc_single_image image="' . $old_image_id . '"', 'vc_single_image image="' . $new_image_id . '"', $content);
        }

        // Update the Content node with the modified content
        $xml_data['post']['Content'] = $content;

        // Update the session with the modified XML data
        PMXI_Plugin::getInstance()->session->xml_data = $xml_data;
    }
}

Answer 1

@Shayne，您的代码的第一个问题是它使用单引号（'）而不是双引号（“），据说使用的是：

注意使用双引号而不是单引号。从 WP All Import 中执行 PHP 函数时必须使用双引号。您不能使用单引号。

我要求 Claude.ai 改进 ChatGPT 中的代码片段，它附带了以下内容，我设法开始工作：

function update_wpbakery_image_ids($post_id, $xml_node, $is_update) {
    // Get the post content
    $content = get_post_field("post_content", $post_id);
    
    // Skip if no content
    if (empty($content)) {
        return;
    }
    
    // Array of WP Bakery shortcodes that contain image IDs
    $shortcode_patterns = array(
        "vc_single_image" => "/\[vc_single_image[^\]]*image=\"(\d+)\"/",
        "vc_gallery" => "/\[vc_gallery[^\]]*images=\"([^\"]+)\"/"
    );
    
    $modified = false;
    
    foreach ($shortcode_patterns as $shortcode => $pattern) {
        preg_match_all($pattern, $content, $matches);
        
        if (!empty($matches[1])) {
            foreach ($matches[1] as $old_ids) {
                // Handle both single IDs and comma-separated lists
                $old_id_array = explode(",", $old_ids);
                $new_id_array = array();
                
                foreach ($old_id_array as $old_id) {
                    $old_id = trim($old_id);
                    
                    // Get the attachment URL for the old ID
                    $old_attachment_url = wp_get_attachment_url($old_id);
                    
                    if ($old_attachment_url) {
                        // Try to find the new attachment ID based on the same filename
                        $filename = basename($old_attachment_url);
                        $new_attachment = get_posts(array(
                            "post_type" => "attachment",
                            "post_status" => "inherit",
                            "fields" => "ids",
                            "meta_query" => array(
                                array(
                                    "value" => $filename,
                                    "compare" => "LIKE",
                                    "key" => "_wp_attached_file"
                                )
                            )
                        ));
                        
                        if (!empty($new_attachment)) {
                            $new_id = $new_attachment[0];
                            $new_id_array[] = $new_id;
                            
                            // Replace in content based on shortcode type
                            if ($shortcode === "vc_single_image") {
                                $content = preg_replace(
                                    "/(\[vc_single_image[^\]]*image=\")" . $old_id . "\"/",
                                    "$1" . $new_id . "\"",
                                    $content
                                );
                            } elseif ($shortcode === "vc_gallery") {
                                $old_ids_pattern = preg_quote($old_ids, "/");
                                $new_ids = implode(",", $new_id_array);
                                $content = preg_replace(
                                    "/(\[vc_gallery[^\]]*images=\")" . $old_ids_pattern . "\"/",
                                    "$1" . $new_ids . "\"",
                                    $content
                                );
                            }
                            
                            $modified = true;
                        }
                    }
                }
            }
        }
    }
    
    // Update post content if modifications were made
    if ($modified) {
        wp_update_post(array(
            "ID" => $post_id,
            "post_content" => $content
        ));
        
        // Clear any caches
        clean_post_cache($post_id);
    }
}

我将此函数添加到函数编辑器中，该编辑器可在 WP All Import Pro 流程中使用。
