            }
            return $QUERY;
        }

    }

Controller

function import_dosen()
    {
        $this->data['title']="Import Data Dosen";
        $this->load->view("admin/v_import_dosen",  $this->data);

    }
    function save_dosen()
    {

        if(isset($_FILES['csv_dosen']['name']))
        {
            $csv_dosen=$_FILES['csv_dosen']['name'];
            $handle = fopen($csv_dosen,"r");
            $this->load->library('csv_import');
            $csv=new csv_import(".$handle.",",","dosen");
            $query=$csv->export();
            $this->m_dosen->eksekusi($query);
//            $check_file=  explode(".", $csv_dosen);
//            if(strtolower($check_file[1])=="csv")
//            {
//                $csv_dosen=$_FILES['csv_dosen']['temp_name'];
//                $handle = fopen($csv_dosen,"r");
//                while (($data = fgetcsv($handle, 1000,",")) !== FALSE)
//                {
//                    echo "haha";
//                }
//            }
//            else{echo "bukan file csv";}
            //$handle = fopen($csv_dosen,"r"); 
            //$csv_dosen_type=$_FILES['csv_dosen']['type'];
            //$csv_dosen_size=$_FILES['csv_dosen']['size'];
        }
        //echo $handle;
    }

型号

<?php
class M_dosen extends CI_model
{
    function __contruct()
    {
        parent::__construct();
    }

    function eksekusi($query)
    {
    //echo "<br/>";
    //echo count($query);
        for($i=1;$i<count($query);$i++)
        {
            $this->db->query($query[$i]);
            //echo $query[$i];
            //echo "<br/>"
        }
    }
}
?>

当我运行此代码时，错误显示[function.fopen]:无法打开流:没有这样的文件或目录。 我是如何解决这个问题的？ 我希望你能帮助解决这个问题。 谢谢。

根据您的库，您必须将文件名传递给 Csv_impot 构造函数。但是您正在传递文件处理程序。

因此更改您的代码如下。

//general oops method:
$csv=new csv_import($csv_dosen,",","dosen");

//In CI,
 $this->load->library('csv_import',array($csv_dosen,",","dosen")); // no need to create object again. Array of values will be parameter for constructor.
