What's the best way to fetch the next page in post archives and other lists like search results?
This question has been asked many times already, but the answers not good enough for me. So far, I've found two ways of doing it.
Using an AJAX request to the standard URL (like
example.com/category/mycat/page/2). This is done using the
$.loadfunction of JQuery which strips the result leaving only the contents of some block with the specified id. I believe this is inefficient both for the client (because unnecessary content is loaded and processed) and for the server (because such a request processes menus, widgets, etc., that are not needed).
With a custom ajax handler using the
add_actionfunction. The big problem with this option is that the handler is not universal! It circumvents the normal query parsing, creating a custom
WP_Queryobject instead. Clearly, this is not the way.
I am considering the following:
Register a query variable that would make the template display the page in JSON format and make a request like so:
example.com/category/mycat/page/2?showjson=true. In the theme check for this variable and adjust output accordingly.
wp_localize_scriptpass them to the script. Then make the AJAX call with these variables and handle them appropriately. (Basically, this would be a beefed-up version of option 2 above).
Then maybe there is some other way of doing this?
ADDED: Making a custom handler could be potentially used to improve performance, as not all of Wordpress needs to be loaded.
