Filter the URL of next_posts_link & previous_posts_link

by

I am working with the qTranslate plugin to create a multi-lingual website. The plugin does a great job of translation except for on the next_posts_link & previous_posts_link template tags.

When a user has selected a different language the URL should change from:

http://mysite.com/test/page/2 (for default language)

to

http://mysite.com/fr/test/page/2 (for french language)

The plugin provides functions for modification/translation of URLs using the qtrans_convertURL($url) function. The problem I am having is finding a suitable hook or filter that will allow me to modify the URL output by the next_posts_link & previous_posts_link template tags.

The closest two WordPress filters I have found are:

add_filter('next_posts_link_attributes', 'my_next_attr');
add_filter('previous_posts_link_attributes', 'my_prev_attr');

Any tips would be most welcome.

Run a filter on get_pagenum_link and you should be able to do what you want.

The next_posts_link / previous_posts_link functions each call functions that in turn call other functions, which eventually route back to the get_pagenum_link function which provides a filter by the same name.

It should give you the control you need, though post a comment if you specifically need an example.

For the singular post link functions, ie. next_post_link / previous_post_link (note the non-plural other readers) there’s a filter hook with a matching name, eg. next_post_link and previous_post_link..
