Delete multiple rows in Codeigniter by multiple columns

Roland :

I have an associative array, like:

array(3) {
  [0]=>
  array(2) {
    ["userId"]=>
    string(1) "10"
    ["customerId"]=>
    string(3) "1809"
  }
  [1]=>
  array(2) {
    ["userId"]=>
    string(1) "13"
    ["customerId"]=>
    string(3) "1094"
  }
  [2]=>
  array(2) {
    ["userId"]=>
    string(1) "45"
    ["customerId"]=>
    string(2) "210"
  }
}

I'm trying to delete these rows from database, but I can't find correct Codeigniter' query to run.

The generated query should be like this:

DELETE FROM table
WHERE (userId,customer_id) IN ( (10,1809),(10,1809),(45,210) )

If I try this

$this->db->where_in( '(userId, customer_id)', array( array(10,1809), array(10,1809), array(45,210) ));
$this->db->delete('table');
die(var_dump($this->db->last_query()));

I get this, which is not correct, of course:

DELETE FROM `table`
WHERE (userId, customer_id) IN(Array, Array, Array)

Boominathan Elango :

Get the associated array values into single array then passit into query

$assoicative_array = array(array(10,20,30));
    $ids=array();
    foreach($assoicative_array as $key =>$value ){
        $ids[]=$value;
    }
    $this->db->where_in('userId',$ids);
    $this->db->where_in('customer_id',$ids);
    $this->db->delete('table');
    die(var_dump($this->db->last_query()));
