i have a simple searchbox in codeigniter, the controller is like below:

function searchtrack() {
    $this->load->model('excel_import_model');
    if(isset($_POST['submittrack'])) {
        $awb=$this->input->post('awb');
        $data['slt']= $this->excel_import_model->searchtrack($awb);
        $this->load->view("searchtrack",$data);
    }
}
}

the model is like below:

public function searchtrack($awbno) {
    $this->db->select('*');
    $this->db->where("awb", $awbno);
    $this->db->from('consignments');
    $query = $this->db->get();
    $result = $query->result();
    return $result;
}

and finally the display view:

<?php
  foreach($slt as $val){ echo $val->id; }
?>

however this not giving me any values, the post input is getting passed to the controller and the database column and all is fine, can anyone please tell me what is wrong in here thanks in advance

CodePudding user response：

In your model, replace "where" with "like". "Where" look for specific data where "like" look for similar data.

public function searchtrack($awbno) {
    $this->db->select('*');
    $this->db->like("awb", $awbno, 'both');
    $this->db->from('consignments');
    $query = $this->db->get();
    $result = $query->result();
    return $result;
}

To control where the wildcard (%) placing in "like" method, a third parameter is used.

$this->db->like('awb', $awbno, 'before');    // Produces: WHERE `title` LIKE '%match' ESCAPE '!'
$this->db->like('awb', $awbno, 'after');     // Produces: WHERE `title` LIKE 'match%' ESCAPE '!'
$this->db->like('awb', $awbno, 'none');      // Produces: WHERE `title` LIKE 'match' ESCAPE '!'
$this->db->like('awb', $awbno, 'both');      // Produces: WHERE `title` LIKE '%match%' ESCAPE '!'
