php - codeigniter active record using like,or,match in the same query -


i have been stuck in phase hour.

my purpose make search using table tag_name, if in tag_name give no_result want using product name table condition.or can result both condition above.

thanks kindness here:

function search_products($searchstr) {      $this->db->select('a.*, b.,c.*,c.id id_product',false);      $this->db->from('tags_events ',false);      $this->db->join('products b','a.product_id = b.id ',false);      $this->db->join('products_details c', 'b.id = c.product_id', 'left');      $this->db->where("match (tag_name) against ('{$searchstr}')or b.product_name '%$searchstr%' ", null, false);      $this->db->group_by("b.product_name");      $query=$this->db->get();      return $query; }

i think problem solve if use mysql pattern matching

mysql provides standard sql pattern matching form of pattern matching based on extended regular expressions similar used unix utilities such vi, grep, , sed.

if needing explain detail, can visit link : http://dev.mysql.com/doc/refman/5.0/en/pattern-matching.html
