How to cache a page with custom template without html tags

    Hi everybody,

    I am using page cache, and I would like the sidebar of my cached pages to be able to load dynamic content with ajax from a json file (which basically contains the list of latest posts, etc.). Everything works, except when it comes to caching the json file.

    The trick I am currently using is to have a dummy page (ie, one I create at wp-admin/edit.php?post_type=page) rendered in a jsoncontent.php “template”. The template is really a php file that generates some json, and never uses the dummy page.

    Unfortunately, W3 Total Cache refuses to cache my page if there is no <html><body> … </body></html> tags in the page template. Without modifying anything else, if I add these tags around my json string in jsoncontent.php (which, of course, I do not want to do), the cache works fine. So, is there any reason why W3 Total Cache requires what it caches to be actual html content?

    Or does anybody know of a better way to cache some json that is to be loaded dynamically by other cached pages?

    Thank you very much,
    Nauhaie

    Caching JSON is supported in latest release.

    Wonderful! Thanks a lot. It works perfectly, and as expected! Now, I can simply put any php-generated content into a pseudo page template, and it gets cached the way I need it to be!

    I think this question might fit into this thread. I’m trying to cache a page that is basically printing out an xml file (see https://www.wprecipes.com/creating-user-defined-rss-feeds-in-wordpress ). I did this by creating a custom page template. The file does not contain <html> or <body> tags. Is it possible to get these pages to cache?

    Thanks!

    As far as I understand, yes. With the lastest update of W3TC, it should work. However, the file will be sent with an HTML mime-type instead of xml (which is not that much of a problem in fact).

    Hmmm..No dice. The Total Cache comment is at the bottom of the page. But the plugin isn’t generating any cache files. Do you think I need to add a new page under “Specify page headers:”?

    To cache feeds you need to enabled caching of feeds on the Page Cache settings page.
