Caching pages doesn't executes with external param

[Jimbos]

Hello, I'm trying to cache some queries. Everything works correctly, but I encounter issues when I try to insert one or more external variables into the function:

$name = $cache->get('cachedname', "+2 minutes", function($pages) { 
    return $pages->find("template=names, parent=1195, id=$nameid, status=published, limit=3");
}); 

Can you help me?

I would assume the $nameid variable is not available in your closure unless you add use ($nameid) to include it. $pages is available only because WireCache supports optionally passing API variables as arguments.

This should work:

$name = $cache->get('cachedname', "+2 minutes", function($pages) use($nameid) { 
    return $pages->find("template=names, parent=1195, id=$nameid, status=published, limit=3");
}); 

Here is some documentation about closures: PHP: Anonymous functions - Manual

Also, your cache function only works as expected if the $nameid variable is the same every time you use a cached version of the query. To get around this, you should make the cache key depend on it, e.g.:

$name = $cache->get("cachedname-$nameid", "+2 minutes", function($pages) use($nameid) { 
    return $pages->find("template=names, parent=1195, id=$nameid, status=published, limit=3");
});
