php - 无法从表中返回数据 - Codeigniter

Question

下面的查询只返回一个结果，即使表中有多个 user_is 为 2 的条目。我不确定我做错了什么。

function get_payments($user_id) 
{
$sql = "SELECT txn_id, payer_email FROM orders WHERE user_id = ?";
$query = $this->db->query($sql, $user_id);

//echo $this->db->last_query();

if($query->num_rows() != 0) {
  foreach($query->result() as $payment)
  {
    $data[] = $payment;
    return $data;
  }
}else{
    return false;
}

}

这就是 $this->db->last_query();返回。 SELECT txn_id, payer_email FROM orders WHERE user_id = '2'

Controller :

$profile_data['user_payments'] = $this->profile_model->get_payments($user_id);    

查看:

<?php 
//var_dump($user_payments);
  foreach($user_payments as $payment)
  {
    echo '<p>';
    echo $payment->txn_id;
    echo $payment->payer_email;
    echo '</p>';
  }
?>

Answer 1

试试这个:

<?php 
function get_payments($user_id){
    $this->db->select('txn_id, payer_email')
        ->from('orders')
        ->where('user_id', $user_id);
    $qry = $this->db->get();
    $res = $qry->result();
    if($res){
        return $res;
    }else{
        return false;
    }

}
?>
