如何在functions.php中添加此代码？文件未上传。代码正常，但文件未移至目标文件夹。

Answer 1

代码移动上传文件。

 if ( ! function_exists( 'wp_handle_upload' ) ) require_once( ABSPATH . 'wp-admin/includes/file.php' );
    $uploadedfile = $_FILES['upload_captcha_background'];
    $upload_overrides = array( 'test_form' => false );
    add_filter('upload_dir', 'my_upload_dir');
    $movefile = wp_handle_upload( $uploadedfile, $upload_overrides );
    remove_filter('upload_dir', 'my_upload_dir');
    
    if ( $movefile ) {
        echo "File is valid, and was successfully uploaded.\n";
        var_dump( $movefile);
    } else {
        echo "Possible file upload attack!\n";
    }
    
    function my_upload_dir($upload) {
    
      $upload['subdir'] = '/sub-dir-to-use' . $upload['subdir'];
    
      $upload['path']   = $upload['basedir'] . $upload['subdir'];
    
      $upload['url']    = $upload['baseurl'] . $upload['subdir'];
    
      return $upload;
    
    }
