Working with Custom Fields

Most settings that govern display of galleries in NextGEN are global – you set them in the main options area, and they apply across all galleries. Some gallery displays can be customized using NextGEN shortcodes.

Custom fields provide another means to customize individual galleries by using WordPress’s custom field capability to apply options to specific post or pages.

How to Edit Custom Fields To edit custom fields, scroll to the bottom of any page or post (be sure that your Screen Setting are set to show “Custom Fields”). Select a specific custom field and enter a key / value for this post. Here is the list of all possible parameters :

CUSTOM FIELDS & WORDTUBE
Along the custom fields above, NextGEN has offered some integration with the WordTube WordPress plugin in the past. Since the Photocrati acquisition, we have not evaluated this functionality to see if this is still function. Still, for documentation purposes, we want to be sure all knowledge is made available.

NextGEN offers a set of custom fields that allow you to change all settings of the media player for each post/page. So you can add plugins, autostart a file, resize it and more without a effect on other media files. Here is the list of all possible parameters for the custom fields:

  • wt_usewatermark
  • wt_controlbar
  • wt_skinurl
  • wt_playlist
  • wt_backcolor
  • wt_frontcolor
  • wt_lightcolor
  • wt_screencolor
  • wt_displayclick
  • wt_stretching
  • wt_plugins
  • wt_custom_vars
  • wt_showfsbutton
  • wt_volume
  • wt_bufferlength
  • wt_width
  • wt_height
  • wt_media_width
  • wt_media_height
  • wt_playlistsize
  • wt_LTchannelID
  • wt_shuffle
  • wt_overstretch
  • wt_quality
  • wt_activateAds

Example: You can add a video with the shortcode [ media id=3 ] and the custom field wt_plugins with the value metaviewer-1 and custom field wt_custom_vars with the value metaviewer.position=left. Shortcode format might be: [ media id=3 width=480 height=320 ]

Example: If you add as custom field as name wt_plugins and the value rateit-2. Then you can use the plugin RateIt.
