RSS Feed Widget [rfw-youtube-videos] Shortcode

The RSS Feed Widget shortcode ‘rfw-youtube-videos’ displays YouTube videos in a WordPress site. It retrieves video IDs stored in the ‘rfw_sc_ids’ option and embeds them into iframes. The shortcode accepts parameters like ‘number’ (default is 3) to limit the number of videos. ‘Fullscreen’, ‘bgcolor’, ‘width’, ‘height’, and ‘margin’ attributes are for customization.

Shortcode: [rfw-youtube-videos]


Here is a list of all possible rfw-youtube-videos shortcode parameters and attributes:

  • number – determines the number of YouTube videos to display
  • fullscreen – if set to true, videos will be displayed in fullscreen mode
  • bgcolor – sets the background color of the video display area
  • width – sets the width of the video display area
  • height – sets the height of the video display area
  • margin – sets the margin around the video display area

Examples and Usage

Basic example – Display three YouTube videos using the ‘rfw-youtube-videos’ shortcode. The number of videos is set by the ‘number’ attribute.

[rfw-youtube-videos number=3 /]

Advanced examples

Display five YouTube videos in fullscreen mode. The ‘number’ attribute sets the number of videos, and the ‘fullscreen’ attribute enables fullscreen mode.

[rfw-youtube-videos number=5 fullscreen=true /]

Show a single YouTube video with a custom background color. The ‘bgcolor’ attribute sets the background color of the video container.

[rfw-youtube-videos number=1 bgcolor="#ff0000" /]

Display four YouTube videos with custom width, height, and margin. The ‘width’, ‘height’, and ‘margin’ attributes allow you to customize the size and positioning of the video container.
