Grouping WHERE clause logic with CodeIgniter active record query


I've run into a problem using several "like" in my sql-query (generated with Codeigniter's activerecord):

SELECT *
FROM (`posts`)
WHERE
    `city` LIKE '%test%'
    AND `title` LIKE '%%'
    OR `text` LIKE '%%'

Thing is, it appears to read this query as if there was a parenthesis around the first like and the second like, but I want there to be a parenthesis around the second and the last like (I want it to compare if the last or the next to last works).

How can I achieve this using Codeigniter's Active Record class?

Current code:

if($type != 0)
    $this->db->where('type', $type);
    
$this->db->like('city', $area);
$this->db->like('title', $words);
$this->db->or_like('text', $words);
    
return $this->db->get('posts')->result_array(); 

Solution

  • I don't think CI is adding any paranthesis. It will add an 'AND' between the first two statements and an 'OR' between the last two. To achieve what you want, I would write my own statement. It's very straightforward.

    $sql = SELECT * FROM 'posts' WHERE city LIKE ? AND ( title LIKE ? OR text LIKE ? );
    $query = $this->db->query($sql, array($area, $words, $words));
    

    Notice how I've used binding. This automatically escapes characters for you.
