Answer 1

You can use following logic in your query:
....
$this->db->or_like('tr.organizerName',$searchText);
$this->db->or_like('tr.location',$searchText);
....
....
It's done :)

Answer 2

The error is with the SQL query being generated, not from PHP.
Instead of this big where condition you need need to use query grouping as outlined in https://www.codeigniter.com/user_guide/database/query_builder.html#query-grouping
$likeCriteria = " (tr.organizerName LIKE '%".$searchText."%'
OR tr.location LIKE '%".$searchText."%'
OR tr.phone LIKE '%".$searchText."%'
OR tr.email LIKE '%".$searchText."%'
OR tr.level LIKE '%".$searchText."%'
OR tr.gender LIKE '%".$searchText."%')";
$this->db->where($likeCriteria);
I haven't actually used codeIgnitor, but based on a quick look at the docs you probably need to replace the problematic block with something like this:
$this->db->group_start()
->or_where(tr.organizerName LIKE "%{$searchText}%")
->or_where(tr.location LIKE "%{$searchText}%")
->or_where(tr.phone LIKE "%{$searchText}%")
->or_where(tr.email LIKE "%{$searchText}%")
->or_where(tr.level LIKE "%{$searchText}%")
->or_where(tr.gender LIKE "%{$searchText}%")
->group_end();
It's worth noting that you could use some business logic to improve this query as well. For instance you could recognise when the search term is a phone number, or an email and restrict the query accordingly

here is my solution with query grouping
function listing($searchText = '', $page, $segment)
{
$this->db->select('tr.*,group_concat(tg.groundname) as grplist ');
$this->db->from('tb_tournament as tr ');
$this->db->join('tournamentground as tg', 'tr.tournamentId=tg.tournamentId', 'left');
$this->db->where('tr.is_deleted','0');
if(!empty($searchText)) {
$this->db->group_start()
$this->db->like('tr.organizerName',$searchText);
$this->db->or_like('tr.location',$searchText);
$thsi->db->group_end()
}
$this->db->group_by('tr.tournamentId');
$this->db->order_by('tr.tournamentId', 'DESC');
$this->db->limit($page, $segment);
$query = $this->db->get();
$result = $query->result();
//print"<pre>";
//print_r($result);
return $result;
}
