声明取消选中复选框codeigniter

Question

我想要做的是未经检查的条件。复选框。只有选中的（复选框）可以工作 循环。如果复选框没有被检查，我该如何阻止foreach运行？

样本循环。

$count = count($waybillno); 

    for ($i = 0; $i < $count; $i++) { 

      $data = array(
       'waybillno' => $waybillno[$i], 
       'quantity' => $quantity[$i], 
       'waybilldate' => $waybilldate[$i], 
       'declared_value' => $declared_value[$i], 
       'consignee' => $consignee[$i], 

      );

EDITED
尝试：

$count = (count($waybillno)); 
for ($i = 0; $i < $count; $i++) { 
    if(isset($waybillno[$i]) && $waybillno[$i] != ""){ 
     $data = array(
     'waybillno' => $waybillno[$i], 
     'quantity' => $quantity[$i], 
     'waybilldate' => $waybilldate[$i], 
     'declared_value' => $declared_value[$i], 
     'consignee' => $consignee[$i], 
     ); 
     #update query here 
    } 
}
