Use getResources to show posts with a certain tag

Struggling a little to get my head around using geResources to only show posts with a certain tag.

I haven't had to do this since the days of Ditto on Evo, so am more than a little rusty.

My basic call is:

[[!getResources? &parents=`4` &limit=`5` &tpl=`blogPost` &includeContent=`1` &showHidden=`1`]]

Presumably I need to add some code telling it to include the tv 'tags' to process that tv, and to only display certain tags.

As anyone got an example of this?

Thanks

You need to use tvfilters. Here's how:

[[!getResources? &parents=`4` &limit=`5` &tpl=`blogPost` &includeContent=`1` &showHidden=`1` &tvFilters=`tags==%[[*customtag]]%`]]

This would force getResources to only return resources that contain the tag customtag.

If you want more than one tag, you would use the or filter:

[[!getResources? &parents=`4` &limit=`5` &tpl=`blogPost` &includeContent=`1` &showHidden=`1` &tvFilters=`tags==%[[*customtag]]%||tags==%[[*customtag2]]%||`]]

The percentage sign (%) searches for the exact values.

More on this on the official getResources documentation page.

You should probably call your getResources uncached or use a cache manager extra like getCache. This could speed up the pageload for your users and your server will buy you a beer if you do that. [ed. note: treigh last edited this post 13 years, 5 months ago.]

Thanks. That works a treat.

I'll take a look at getCache.

Glad it worked.

getCache is also super straightforward.

You can use it like this:

[[!getCache? &cacheExpires=`1200` &element=`getResources` &parents=`4` &limit=`5` &tpl=`blogPost` &includeContent=`1` &showHidden=`1` &tvFilters=`tags==%[[*customtag]]%`]]

Always call it uncached and feel free to specify your preferred cache expiry time.

Good luck!
