                                        <?php endforeach ?> 

Help me to solve this problem...thanks in advance

Answer 1

You are joining the same table on line no. 7, that's why its repeating. May be,you want to join 'purchaseitem' table. If so,then change that line to this -

   $this->db->join('purchaseitem', 'purchasebill.date = purchaseitem.billdate','left outer');
