grouping where clauses in codeigniter

grouping where clauses in codeigniter  using -'php,mysql,codeigniter,activerecord'

I want to produce the following SQL code using Active Records in Codeigniter:

WHERE name != 'Joe' AND (age < 69 OR id > 50)

Doing the following seems to be as far as I can get, I cant figure out how to group them

$this->db->select()->from('users')->where('name !=', 'Joe')->where('age <', 69)->or_where('id <', $id);

Any ideas? My SQL query is too complex so I dont wish to rewrite everything in traditional SQL.


My SQL code is dynamically generated depending on the values of certain parameters passed into the model method. The problem with not being able to use parenthesis causes a problem because the operator precedence is such that AND is evaluated first before OR.

*Here is a chunk of my active records code, where there are some other code before and after it:

            ... some $this->db->where() ...
            ... some $this->db->where() ...

    if($price_range) {
        $price_array = explode('.', $price_range);
        for($i = 0; $i < count($price_array); $i++) {
            if($i == 0) {
                $this->db->where('places.price_range', $price_array[$i]);
            } else {
                $this->db->or_where('places.price_range', $price_array[$i]);


            ... some $this->db->where() ...
            ... some $this->db->where() ...

The problem comes because I am using $this->db->or_where() which introduces a OR clause that throws the operator precedence into disarray without being able to use ( ) to change the order.

** Is there any way to solve this? **
