子文件夹即将到来时未显示的值

Question

这是我的表

tag  enabled

bank   1
WT     1
Credit 1
Debit  1
EMI    1

我的查询是：

    $sql = "SELECT * FROM payment WHERE enabled = '1'";
    $result = mysql_query($sql);
    while($data = mysql_fetch_assoc($result)) {
        $gateway='';
        if($data['tag']=='credit') {
            $gateway='/'.getPaymentGateway($data['gateway'],'tag');
        }

        include('payment/'.$data['tag'].$gateway.'/display.php');   

        ...
    }

问题是，它显示直到信用，没有显示借记和EMI 这是因为，信用证有子文件夹。

函数getPaymentGateway是：

function getPaymentGateway($id,$field) {      
    $sql = "SELECT * FROM    payment_gateway  WHERE id = '".$id."'";
    $result = mysql_query($sql);
    $data = mysql_fetch_assoc($result);
    return   $data[$field];

}

你不需要做关联，你没有加入任何表格保持简单。

 if(!$result){
      // error with query 
      return mysql_error();
    }else{
      while($data = mysql_fetch_array($result)){
        $gateway='';
        if($data['tag']=='credit') $gateway='/'.getPaymentGateway($data['gateway'],'tag');
        include('payment/'.$data['tag'].$gateway.'/display.php');   
     }
    }
