Codeigniter active record update statement with a join

Question

This is the query that i\'m trying to achieve via active record:

UPDATE `Customer_donations` cd 
join Invoices i on i.cd_id = cd.cd_id 
set cd.amount = \'4\'         


        

Answer 1

How about the solution below? A bit ugly but it achieved what you expected in your question.

$invoiceId = 13;
$amount = 4;
$data = array('cd.amount'=>$amount, 'cd.amount_verified'=>'1');

$this->db->where('i.invoice_id', $invoiceId);

$this->db->update('Customer_donations cd join Invoices i on i.cd_id = cd.cd_id', $data);
