使用html输入类型文件上传文件时的空白页面

Question

我想将excel文件上传到一个文件夹，然后将文件名上传到数据库中，但它给了我一个带有网址的空白页面 “http://localhost/myweb.com/admin/upload?file=tes+upload.xlsx”。 “tes upload”是文件名。该文件未上传到该文件夹​​以及数据库。我不知道我错过了什么。我将文件夹权限设置为777。

我的表格：

<form action="<?php echo site_url('admin/upload')?>" enctype="multipart/form-data">
    <input type="file" name="file" accept="application/vnd.ms-excel,application/vnd.openxmlformats-officedocument.spreadsheetml.sheet">
    <input type="submit" class="btn btn-success" value="submit">
</form>

我的控制器：

function upload()
{
    if (!empty($_FILES))
    {
        $filename = $_FILES["file"]["name"];
        $file_basename = substr($filename, 0, strripos($filename, '.'));
        $file_ext = substr($filename, strripos($filename, '.'));
        $tempFile = $_FILES['file']['tmp_name'];
        $data = "admin".uniqid().$file_ext;
        $targetPath = getcwd() . '/uploads/';
        $targetFile = $targetPath . $data ;

        move_uploaded_file($tempFile, $targetFile);

        $file_path =  FCPATH.'/uploads/';
        require_once APPPATH."/third_party/PHPExcel.php";
        require_once APPPATH . "/third_party/PHPExcel/IOFactory.php"; 

        $inputFileName = $file_path; 
        $objPHPExcel = PHPExcel_IOFactory::load($inputFileName);
        $allDataInSheet = $objPHPExcel->getActiveSheet()->toArray(null,true,true,true);
        $arrayCount = count($allDataInSheet);  // Here get total count of row in that Excel sheet
        $regex = "~\d{5}~";
        $dataexcel = Array();

        for($i=1;$i<=count($dataexcel);$i++)
        {
            $dataexcel[$i]['to_name']=$allDataInSheet[$i]["A"];
            $dataexcel[$i]['to_address']=$allDataInSheet[$i]["B"];
            $dataexcel[$i]['to_phone']=$allDataInSheet[$i]["C"];
            preg_match($regex, $allDataInSheet[$i]["B"], $result);
            $dataexcel['to_zipcode'] = $result[0];
        };

        $data_user = array(
            'status'         => '1',
            'filename_admin' => $data,
        );

        $this->load->model('excel');
        $this->excel->upload_excel($allDataInSheet,$data_user);
    }
}

我的模特：

function upload_excel($allDataInSheet)
{
    $regex = "~\d{5}~";

    array_shift($allDataInSheet);

    foreach ($allDataInSheet as $key)     
    {
        preg_match($regex, $key['B'], $result);

        $data = array(
        'request_id'         =>   $request_id,
        'to_name'            =>   $key['A'],
        'to_phone'           =>   $key['C'],
        'to_address'         =>   $key['B'],
        'to_zipcode'         =>   $result[0],
        'tariff'             =>   '0'
        );

        $this->db->insert('excel', $data);
        $this->db->update('request',$request_id);
    }
}

请帮帮我。提前致谢
