how to show data with ajax using codeigniter-CodePudding

i have tabel_item

id |    name    | location
1  |   item a   |   3,5 
2  |   item b   |   4

here I made a model

  public function db_barangGetMaster($postData){
    if(isset($postData['location']) ){
      $this->db->select("*");
      $this->db->from('tabel_item as a');
      $this->db->where("location", $postData['location']);
      
      $response = array();
      $query = $this->db->get()->result();
      foreach($query as $row ){
            $response[] = array(
            "id" =>$row->id,
            "name" =>$row->name,
            "lokasi" =>$row->location
        );
      }
    if (count($response)) {
        return $response;
    } else {
        return ['response' => 'not found'];
    }}
 }

$postData = parameter is location

here as an example the content in the parameter is 3 why not show?

how to display the data, if the parameter is 3 then what appears is item a if the parameter is 5 then item a

CodePudding user response：

location must be array. use where_in instead of where

$this->db->where_in("location", [$postData['location']]);

Or use

WHERE (location ='.$postData['location'].' 
OR location LIKE "'.$postData['location'].',%"
OR location LIKE "%,'.$postData['location'].'"
OR location LIKE "%,'.$postData['location'].',%"
)
