【问题描述】：

我已经编写代码来上传文件夹和 wordpress 媒体库中的文件。文件将上传到 wordpress 文件夹，但问题是它没有在媒体库中移动。

函数 fb_save_custom_user_profile_fields( $user_id ) {

    $uploadUrl= wp_get_upload_dir();

    if ( !current_user_can( 'edit_user', $user_id ) )
        return FALSE;

        $rel = $_POST['relation'];

    update_user_meta( $user_id, 'fname_'. $rel, $_POST['fname'] );
    update_user_meta( $user_id, 'mname_'.$rel, $_POST['mname'] );
    update_user_meta( $user_id, 'lname_'. $rel, $_POST['lname'] );
    update_user_meta( $user_id, 'relation', $_POST['relation'] );
    update_user_meta( $user_id, 'bod_'. $rel, $_POST['bod'] );
    update_user_meta( $user_id, 'education_'.$rel ,$_POST['education'] );
    update_user_meta( $user_id, 'occupation_'. $rel, $_POST['occupation'] );

    // update_user_meta( $user_id, 'picture_'. $rel, $uploadUrl['url']."/".$_POST['picture'] );

    if($_FILES['picture']['name'] != ''){
    $uploadedfile = $_FILES['picture'];
    $upload_overrides = array( 'test_form' => false );

    $movefile = wp_handle_upload( $uploadedfile, $upload_overrides );
    $imageurl = "";
    if ( $movefile && ! isset( $movefile['error'] ) ) {
       $imageurl = $movefile['url'];
       echo "url : ".$imageurl;

       update_user_meta( $user_id, 'picture_'. $rel, $_FILES['picture']['name'] );
    } else {
       echo $movefile['error'];
    }
  }
}
add_action( 'show_user_profile', 'fb_add_custom_user_profile_fields' );
add_action( 'edit_user_profile', 'fb_add_custom_user_profile_fields' );

您需要将文件另存为附件：

        // Save to media library
        $filename = $_FILES['picture']['name'];
        $wp_filetype = wp_check_filetype($filename, null );
        $attachment = array(
           'guid' => $imageurl,
           'post_mime_type' => $wp_filetype['type'],
           'post_title' => sanitize_file_name($filename),
           'post_content' => '',
           'post_status' => 'inherit'
        );
        $attach_id = wp_insert_attachment( $attachment, $file );
        require_once(ABSPATH . 'wp-admin/includes/image.php');
        $attach_data = wp_generate_attachment_metadata( $attach_id, $file );
        $res1= wp_update_attachment_metadata( $attach_id, $attach_data );

所以基本上，您的代码将如下所示：

add_action( 'show_user_profile', 'fb_add_custom_user_profile_fields' );
add_action( 'edit_user_profile', 'fb_add_custom_user_profile_fields' );
function fb_save_custom_user_profile_fields( $user_id ) {

    $uploadUrl = wp_get_upload_dir();

    if ( !current_user_can( 'edit_user', $user_id ) )
            return FALSE;

            $rel = $_POST['relation'];

    update_user_meta( $user_id, 'fname_'. $rel, $_POST['fname'] );
    update_user_meta( $user_id, 'mname_'.$rel, $_POST['mname'] );
    update_user_meta( $user_id, 'lname_'. $rel, $_POST['lname'] );
    update_user_meta( $user_id, 'relation', $_POST['relation'] );
    update_user_meta( $user_id, 'bod_'. $rel, $_POST['bod'] );
    update_user_meta( $user_id, 'education_'.$rel ,$_POST['education'] );
    update_user_meta( $user_id, 'occupation_'. $rel, $_POST['occupation'] );

    // update_user_meta( $user_id, 'picture_'. $rel, $uploadUrl['url']."/".$_POST['picture'] );

    if($_FILES['picture']['name'] != ''){
        $uploadedfile = $_FILES['picture'];
        $upload_overrides = array( 'test_form' => false );

        $movefile = wp_handle_upload( $uploadedfile, $upload_overrides );
        $imageurl = "";
        if ( $movefile && ! isset( $movefile['error'] ) ) {
             $imageurl = $movefile['url'];


                // Save to media library
                $filename = $_FILES['picture']['name'];
                $wp_filetype = wp_check_filetype($filename, null );
                $attachment = array(
                   'guid' => $imageurl,
                   'post_mime_type' => $wp_filetype['type'],
                   'post_title' => sanitize_file_name($filename),
                   'post_content' => '',
                   'post_status' => 'inherit'
                );
                $attach_id = wp_insert_attachment( $attachment, $file );
                require_once(ABSPATH . 'wp-admin/includes/image.php');
                $attach_data = wp_generate_attachment_metadata( $attach_id, $file );
                $res1= wp_update_attachment_metadata( $attach_id, $attach_data );


             echo "url : ".$imageurl;

             update_user_meta( $user_id, 'picture_'. $rel, $_FILES['picture']['name'] );
        } else {
             echo $movefile['error'];
        }
    }
}

无法使用此代码。我对 thi 做了一些更改，现在效果很好。感谢您提供此代码。
嗨@Mahen，如果这个答案已经解决了你的问题，请考虑点击复选标记接受它。
我不认为你可以从互联网上获取任何代码，它会开箱即用，任何代码都需要你自己实现。

【解决方案2】：

通过将这两个“$file”变量更改为这样，我得到了@Ali_k 的答案：

$attach_id = wp_insert_attachment( $attachment, $filename, $user_id );
require_once(ABSPATH . 'wp-admin/includes/image.php');
$attach_data = wp_generate_attachment_metadata( $attach_id, $movefile['file'] );
