How to search full name in codeigniter - codeigniter

Question

My database table structure is as follows.
-------------------------------
| id | f_name | m_name | l_name |
-------------------------------
This is my model that I used to get results.
public function getContactInfo($start,$perpage) // Swapnil
{
$keyword= $this->input->get('keyword'); // vishal
$this->db->like(array('colleges_fname'=>$keyword)); // vishal
$this->db->limit($perpage,$start);
$result = $this->db->get("colleges");
if($result->num_rows()>0) {
return $result->result();
} else {
return false;
}
}
This is my view.
<form class="form-inline ml-3" type="get" action="<?php echo base_url('clerk/collegestudent/view')?>">
<div class="input-group input-group-sm ">
<input class="form-control form-control-navbar" type="search" placeholder="Search" aria-label="Search" name="keyword">
<div class="input-group-append">
<button class="btn btn-navbar" type="submit">
<i class="fas fa-search"></i>
</button>
</div>
</div>
</form>
Currently it searches for the first name only. How to improve my code to search both first name and last name at a time?

Answer 1

public function getContactInfo($start,$perpage) // Swapnil
{
$keyword= $this->input->get('keyword'); // vishal
$this->db->group_start();
$this->db->like('f_name', $keyword, 'after');
$this->db->or_like('l_name', $keyword, 'after');
$this->db->group_end();
$this->db->limit($perpage,$start);
$result = $this->db->get("colleges");
if($result->num_rows()>0) {
return $result->result();
} else {
return false;
}
}
The lines from group start to group end will reproduce something like:
(f_name LIKE "string%" OR l_name LIKE "string%")
If you want to search in both directions remove the third param in the like statements.
