'students.adhar_no' => $searchterm,
'students.samagra_id' => $searchterm,
'students.roll_no' => $searchterm,

$this->db->select('classes.id AS `class_id`,students.id,classes.class,sections.id AS `section_id`,sections.section,students.id,students.admission_no , students.roll_no,students.admission_date,students.firstname, students.lastname,students.image, students.mobileno, students.email ,students.state , students.city , students.pincode , students.religion, students.dob ,students.current_address, students.permanent_address,IFNULL(students.category_id, 0) as `category_id`,IFNULL(categories.category, "") as `category`, students.adhar_no,students.samagra_id,students.bank_account_no,students.bank_name, students.ifsc_code ,students.father_name , students.guardian_name , students.guardian_relation,students.guardian_phone,students.guardian_address,students.is_active ,students.created_at ,students.updated_at,students.gender,students.rte,student_session.session_id')->from('students');
$this->db->join('student_session', 'student_session.student_id = students.id');
$this->db->join('classes', 'student_session.class_id = classes.id');
$this->db->join('sections', 'sections.id = student_session.section_id');
$this->db->join('categories', 'students.category_id = categories.id', 'left');
$this->db->where('student_session.session_id', $this->current_session);
$this->db->group_start();
$this->db->or_like($searcharray);
$this->db->group_end();
$this->db->order_by('students.id');
// $this->db->limit('100');
$query = $this->db->get();

I find in my own searches that I will check to see if the search is for a string that has a space, so I can split it and use it for first and last name:
if( strpos( $searchterm, ' ' ) !== FALSE )
$search_parts = explode(' ', $searchterm);
Then, you may want to make sure that there are two parts:
if( count( $search_parts ) == 2 ){
// you know you have two parts
}
So then you'd be able to use the parts in your array:
'students.firstname' => $search_parts[0],
'students.lastname' => $search_parts[1],
And if they may be out of order:
'students.firstname' => $search_parts[1],
'students.lastname' => $search_parts[0],
I am using a different way of creating a query, but to show you an example, I do this:
if( strpos( $search, ' ' ) !== FALSE )
{
$search_parts = explode(' ', $search);
$sql .= '
OR (
first_name LIKE "%' . $this->db->escape_like_str( current($search_parts) ) . '%" ESCAPE "!" AND
last_name LIKE "%' . $this->db->escape_like_str( end($search_parts) ). '%" ESCAPE "!"
) ';
reset($search_parts);
$sql .= '
OR (
last_name LIKE "%' . $this->db->escape_like_str( current($search_parts) ) . '%" ESCAPE "!" AND
first_name LIKE "%' . $this->db->escape_like_str( end($search_parts) ). '%" ESCAPE "!"
)
';
}
Also, if you don't care about code portability, you should see this answer with CONCAT: Mysql Concat two columns while searching with LIKE
That ends up looking something like this:
// Check if search was input as full name
if( strpos( $search, ' ' ) !== FALSE )
{
$sql .= '
OR ( CONCAT( first_name, " ", last_name ) LIKE "%' . $this->db->escape_like_str( $search ) . '%" ESCAPE "!" )
OR ( CONCAT( last_name, " ", first_name ) LIKE "%' . $this->db->escape_like_str( $search ) . '%" ESCAPE "!" ) ';
}
So, in your case, I think you should be able to do this:
$searcharray = array(
'students.firstname' => $searchterm,
'students.lastname' => $searchterm,
'students.guardian_name' => $searchterm,
'students.adhar_no' => $searchterm,
'students.samagra_id' => $searchterm,
'students.roll_no' => $searchterm,
'students.admission_no' => $searchterm,
'CONCAT(students.firstname, " ", students.lastname)' => $searchterm,
'CONCAT(students.lastname, " ", students.firstname)' => $searchterm
);
