如何上传文本文件并使用Codeigniter在sql中导入其数据?

I have a core PHP script which allows me to upload text file and import its data into sql database.

I want to do the same thing using Codeigniter. I tried by the screen shows me blank white screen when i put the code in CI application.

Below Is My core PHP script for uploading a file and Importing It:

<?php
include_once 'dbconfig.php';
if(isset($_POST['btn-upload']))
{    

    $file = rand(1000,100000)."-".$_FILES['file']['name'];
    $file_loc = $_FILES['file']['tmp_name'];
    $file_size = $_FILES['file']['size'];
    $file_type = $_FILES['file']['type'];
    $folder="uploads/";
    $location =$_FILES['file'];

    // new file size in KB
    $new_size = $file_size/1024;  
    // new file size in KB

    // make file name in lower case
    $new_file_name = strtolower($file);
    // make file name in lower case

    $final_file=str_replace(' ','-',$new_file_name);

        if(move_uploaded_file($file_loc,$folder.$final_file))
    {
        $sql="INSERT INTO tbl_uploads(file,type,size) VALUES('$final_file','$file_type','$new_size')";
        mysqli_query($connection,$sql);


        $handle = fopen("c:/wamp/www/codeigniter/uploads/$file", "r");

         if ($handle) {
                while (($line = fgets($handle)) !== false) {

                     $lineArr = explode("\t", "$line");
                     //var_dump($lineArr); // to make sure array is ok

                     // instead assigning one by onb use php list -> http://php.net/manual/en/function.list.php            
                     list($emp_id, $date_data, $abc, $def, $entry, $ghi) = $lineArr;

                     // and then insert data
                     mysqli_query($connection,"INSERT INTO `daily_data2` (emp_id, date_data, abc, def, entry, ghi) 
            VALUES ('$emp_id', '$date_data', '$abc', '$def', '$entry', '$ghi')");
                }

                fclose($handle);
            }


        ?>
        <script>
        alert('successfully uploaded');
        window.location.href='index.php?success';
        </script>
        <?php


    }
    else
    {
        ?>
        <script>
        alert('error while uploading file');
        window.location.href='index.php?fail';
        </script>
        <?php
    }

}

?>

I dont know how to do this in Codeigniter. Please guide me here

the Ci Form:

     <h2>Upload CSV To Import Users</h2>
        <form method="post" action="<?php echo site_url('admin/attendance/upload');?>" enctype="multipart/form-data">
            <input type="file" name="userfile"  ><br><br>
            <input type="submit" name="submit" value="UPLOAD" class="btn btn-primary">
        </form>
