Codeigniter parentheses in dynamic Active Record query

Question

I\'m producing a query like the following using ActiveRecord

SELECT * FROM (`foods`) WHERE `type` = \'fruits\' AND 
       `tags` LIKE \'%green%\' OR `tags`          


        

Answer 1

Going off of The Silencer's solution, I wrote a tiny function to help build like conditions

function make_like_conditions (array $fields, $query) {
    $likes = array();
    foreach ($fields as $field) {
        $likes[] = "$field LIKE '%$query%'";
    }
    return '('.implode(' || ', $likes).')';
}

You'd use it like this:

$search_fields = array(
    'field_1',
    'field_2',
    'field_3',
);
$query = "banana"
$like_conditions = make_like_conditions($search_fields, $query);
$this->db->from('sometable')
    ->where('field_0', 'foo')
    ->where($like_conditions)
    ->get()
