Hi @galadh
If the query is like this: &type=typeA,typeB
, then you need to add a query for each type listed. It should be something like this:
if (isset($_GET["type"]) && $_GET["type"]!='') {
// get the listed types in an array
$types = explode(',', $_GET[ "type" ]);
// initialize the meta query
$add_args['meta_query']['relation'] = 'OR';
// loop through the types and add it to the query
foreach( $types as $type ){
$add_args['meta_query'] []= array(
'key' => 'tipo_lemma',
'value' => '"'. $type .'"',
'compare' => 'LIKE'
);
}
}
I hope this helps 🙂
