wordpress - 如何以编程方式上传到 wordpress - 保存文件问题

Question

我有循环遍历的数据，这些数据包括标题、内容、服务器上文件的路径以及各种其他信息。

目标是遍历数据并在循环中创建带有 post_meta product_image 的图片的 Worpress 帖子
如:add_post_meta ($ post_id, '_product_image', $ attach_id, true);

我的循环看起来像这样:

    while($row = $STH->fetch()) {  

        $my_post = array(
          'post_title'    => $row->title,
          'post_content'  => $row->description,
          'post_status'   => 'publish',
          'post_author'   => $current_user->ID,
          'post_category' => array(6)
        );


        // Insert the post into the database
        $post_id = wp_insert_post( $my_post );

        add_post_meta( $post_id, 'product_price', 199, true );
        add_post_meta( $post_id, 'product_sub_price', 20, true);

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

        $filename = $row->image_local_name;

        // Path to the file i want to upload into wordpress.
        $path = ABSPATH . 'add/foo/uploads/' . $row->image_local_name;  // Path to file.
        var_dump($path);

        $file_url = $row->image_url;
        $filename = $row->image_local_name;

        $wp_filetype = wp_check_filetype(basename($filename), null );

        $wp_upload_dir = wp_upload_dir();

        // Path i want to save the image(s).
        $save_path = $wp_upload_dir['basedir'] . $wp_upload_dir['subdir'] . $filename;
        var_dump($save_path);


        $attachment = array(
            'post_author' => $current_user->ID, 
            'post_date' => current_time('mysql'),
            'post_date_gmt' => current_time('mysql'),
            'post_title' => $filename, 
            'post_status' => 'inherit',
            'comment_status' => 'closed',
            'ping_status' => 'closed',
            'post_name' => $filename,                                           
            'post_modified' => current_time('mysql'),
            'post_modified_gmt' => current_time('mysql'),
            'post_parent' => $post_id,
            'post_type' => 'attachment',
            'guid' =>  $wp_upload_dir['basedir'] . $filename,   // not sure if this is correct, some advise?
            'post_mime_type' => $wp_filetype['type'],
            'post_excerpt' => '',
            'post_content' => ''
        );


        $attach_id = wp_insert_attachment( $attachment, $save_path, $post_id );

        var_dump($attach_id);

        $attach_data = wp_generate_attachment_metadata( $attach_id, $path );

        var_dump($attach_data);

        $update = wp_update_attachment_metadata( $attach_id,  $attach_data );

        var_dump($update);

        // Add the attach_id to post_meta key: product_image with the value of the attach_id
        add_post_meta( $post_id, '_product_image', $attach_id, true);
    } 

输出:http://pastebin.com/LpNzc1pP

似乎它在数据库中正确存储，但是wordpress创建的图像，例如:racing cars-with-studs-including-free-shipping-mattress-amp ribb.jpg

图像保存在六个版本中，这是正确的，但它们没有保存在我希望放置这些图像的uploads/08 中。

图像存储在这里:

/Applications/MAMP/htdocs/websites/foo.dev/public_html/add/foo/uploads/

如何将这些图像保存在正确的位置？

Answer 1

虽然我没有解决您的具体问题，但我知道您正在尝试完成什么，并且我建议使用 Wordpress API 的替代方法 media_handle_sideload()或 media_sideload_image()功能将图像文件放入媒体库并自动附加到帖子中。

所以而不是:

    $filename = $row->image_local_name;

    $wp_filetype = wp_check_filetype(basename($filename), null );

    $wp_upload_dir = wp_upload_dir();

    // Path i want to save the image(s).
    $save_path = $wp_upload_dir['basedir'] . $wp_upload_dir['subdir'] . $filename;
    var_dump($save_path);


    $attachment = array(
        'post_author' => $current_user->ID, 
        'post_date' => current_time('mysql'),
        'post_date_gmt' => current_time('mysql'),
        'post_title' => $filename, 
        'post_status' => 'inherit',
        'comment_status' => 'closed',
        'ping_status' => 'closed',
        'post_name' => $filename,                                           
        'post_modified' => current_time('mysql'),
        'post_modified_gmt' => current_time('mysql'),
        'post_parent' => $post_id,
        'post_type' => 'attachment',
        'guid' =>  $wp_upload_dir['basedir'] . $filename,   // not sure if this is correct, some advise?
        'post_mime_type' => $wp_filetype['type'],
        'post_excerpt' => '',
        'post_content' => ''
    );


    $attach_id = wp_insert_attachment( $attachment, $save_path, $post_id );

    var_dump($attach_id);

    $attach_data = wp_generate_attachment_metadata( $attach_id, $path );

    var_dump($attach_data);

    $update = wp_update_attachment_metadata( $attach_id,  $attach_data );

    var_dump($update);

    // Add the attach_id to post_meta key: product_image with the value of the attach_id
    add_post_meta( $post_id, '_product_image', $attach_id, true);

你可以使用:
$myAttachmentId = media_handle_sideload( $file_url, $post_id );
这会将图片作为帖子的附件上传到媒体库，然后您可以通过以下方式将其设为“产品图片”:
$myProductImage = add_post_meta( $post_id, '_product_image', $myAttachmentId, true );
