How to use the [series_nav] shortcode #
[series_nav]
if you add this shortcode to a post that is a part of a series, the shortcode will show the series navigation.
It is also possible to use two versions of this shortcode and customize the layout. For example:
[series_nav]%next_post%.........%previous_post%[/series_nav]
The content between the “series_nav” tags will be used for this display. You can use the %tokens% found by going to Series > Templates in your WordPress admin area.
One example is that you can split up the shortcode using the %next_post% and %previous_post% tokens so you can display the links in totally different sections of the post. For example, you can place your post content between these shortcodes:
[series_nav]Click here to go to %next_post%[/series_nav]
[series_nav]Click here to go to the %previous_post%[/series_nav]
How to customize the [series_nav] shortcode #
The default layout is determined by what you have in the “Series Navigation Box” template found by going to Series > Templates in your WordPress admin area.
