No like in getResultArray

the like function return a $this, and the builder class does not have the getResultArray functions.
you need to execute the query first ( you have no action applied, so ci use select as default. to execute your builder ->get() ) https://bcit-ci.github.io/CodeIgniter4/d...cting-data

public function searchPart($data) {
return $this->db->table('par')->like('title', $data)->get();
}
