Previous Post Link
Being used mainly on single post template, this tag display a link to a previous post relative to current post, from a sort list.
This tag must be used within the query loop.
The default WordPress function used for previous naivigational link is previous_post_link. This is very limited in functionality and there is no possibility to apply a sort list and a specific taxonomy term to which the post is related to.
An improvement for that function is previous_post_type_link
Arguments:
previous_post_type_link($format, $link, $argv);
If $argv is empty the archive order will be used.
Parameters
$format(string) Format string for the link. This is where to control what comes before and after the link. '%link' in string will be replaced with whatever is declared as 'link' (see next parameter). 'Go to %link' will generate “Go to <a href=…” Put HTML tags here to style the final results. Defaults to '« %link'.
$link(string) Link text to display. Defaults to previous post’s title ('%title').
$argv(array) List of function arguments:
sort_id – the sort id which order will be used
taxonomy – use the specified sort taxonomy
term_id – use the specified sort taxonomy term
Examples
