Codeigniter，严重性：错误 --> 异常：函数参数太少，管理仪表板显示 HTTP 错误 500

Question

我在日志文件中遇到错误这个

ERROR - 2022-05-13 02:47:21 --> Severity: error --> Exception: Too few arguments to function Transactions_model::get_pending_dash(), 0 passed in /Applications/MAMP/htdocs/application/controllers/admin/Dashboard.php on line 47 and exactly 1 expected /Applications/MAMP/htdocs/application/models/Transactions_model.php 2134

这是第 47 行 dashboard.php 控制器下的确切代码：

$transactions = $this->transactions_model->get_pending_dash();

这是 transactions_model.php 型号下的确切代码：

  // total transactions ////////////////////////////////////////////
  function total_dash_transactions()
  {
    $s= $this->db->select("COUNT(*) as num")->get("transactions");
    $r = $s->row();
    if(isset($r->num)) return $r->num;
    return 0;

    return $result[0]->Transactions;
  }
    
    function get_pending_dash($user) 
    {
        $where = "status = '1' AND type = '2'";
        return $this->db->where($where)->order_by('id', 'DESC')->limit(20)->get("transactions");
    }

Answer 1

因为在你的函数中 get_pending_dash 需要 $user 作为参数，但是根据你的代码你也没有使用它所以如果你没有使用参数就删除 $user 喜欢下面的代码。

function get_pending_dash() 
{
    $where = "status = '1' AND type = '2'";
    return $this->db->where($where)->order_by('id', 'DESC')->limit(20)->get("transactions");
}
