This will only get a series of cl_to's. I'm not sure what that $e is
for, or what the /dev/null style fetchObject call is for, and I'm not
sure what data output you're expecting. So I'll need more information if
you want other information in the rows, a count, or a grouping of things
together.
$res = $db->select(
array('categorylinks', 'imagelinks', 'page'),
array( 'cl_to' ),
array(
'page_id' => $pidsArray,
'page_namespace' => NS_FILE,
),
__METHOD__,
array(),
array(
'imagelinks' => array( 'JOIN', 'il_from=cl_from' ),
'page' => array( 'JOIN', 'page_title=il_to' ),
)
);
foreach ( $res as $row ) {
$row->cl_to;
// [...]
}
(Side-note; Uuuuughhh... A $wg that's not global, raw sql queries,
unescaped SQL concatenation (including what looks like an SQL injection
vector), hardcoded NS number, for() where foreach() is usable, $arr[$i]
instead of $arr[]... that code is........................ <facepalm/>)
