How do I cache this query that I placed in Load.php

[shuban]

Code: [Select]

if(!$user_info['is_guest'])
{
$dbresult = db_query("
SELECT
t.ID_MEMBER, t.ID_ITEM, i.ID_ITEM, i.ID_GROUPToMove
FROM {$db_prefix}store_transactions AS t, {$db_prefix}store_item AS i
WHERE
t.ID_MEMBER = $ID_MEMBER AND t.ID_ITEM = i.ID_ITEM AND i.ID_GROUPToMove != 0", __FILE__, __LINE__);

$found = db_affected_rows();
mysql_free_result($dbresult);

// If the record exists
if ($found == true)
{
$dbresult = db_query("
SELECT
ID_MEMBER
FROM {$db_prefix}store_group_log
WHERE ID_MEMBER = $ID_MEMBER", __FILE__, __LINE__);

$found = db_affected_rows();
mysql_free_result($dbresult);

// If no record exists
if ($found == false)
$context['membership_existed'] = 1;
}
}
My question is, how do I use the forum's caching system to cache this. It is per user based and doesn't get updated often. Also, is it important to cache?

If it is not run all the time then doesn't need to be cached.
