Question

I have written the code to export the data into an excel sheet, but the PHPExcel  libray is not loaded into the code.It shows some error while clicking the button"Export".

错误是： enter image description here

 public function Arrear_Print(){

    $data['page'] = 'export-excel';
        $data['title'] = 'Export Excel data | TechArise';
        $data['startdate'] =$this->input->post('SDate');
        $data['enddate'] = $this->input->post('EDate');
                $this->load->model('Export');
        $data['PName'] = $this->Export->mobileList();
        // load view file for output
        //$this->load->view('header');
        $this->load->view('TipUp_Loan\Arrear_Print', $data);
       // $this->load->view('footer');
}
 public function createXLS() {
        // create file name
        $fileName = 'mobile-'.time().'.xlsx';  
        // load excel library
        $this->load->library('excel');
        $mobiledata = $this->model->Export->mobileList();
        $objPHPExcel = new PHPExcel();
        $objPHPExcel->setActiveSheetIndex(0);
        // set Header
       $objPHPExcel->getActiveSheet()->SetCellValue('A1', 'AcNo');
        $objPHPExcel->getActiveSheet()->SetCellValue('B1', 'Mode');
        $objPHPExcel->getActiveSheet()->SetCellValue('C1', 'Party Name');
        $objPHPExcel->getActiveSheet()->SetCellValue('D1', 'Loan Date');
        $objPHPExcel->getActiveSheet()->SetCellValue('E1', 'Loan Amt');  
        $objPHPExcel->getActiveSheet()->SetCellValue('F1', 'Bal.Amt'); 
        $objPHPExcel->getActiveSheet()->SetCellValue('G1', 'Coll.Amt');  
        $objPHPExcel->getActiveSheet()->SetCellValue('H1', 'Rec.Amt');  
        $objPHPExcel->getActiveSheet()->SetCellValue('I1', 'Phone.No');
        // set Row
        $rowCount = 2;
        foreach ($mobiledata as $element) 
        {
            $objPHPExcel->getActiveSheet()->SetCellValue('A' . $rowCount, $element['TAcNo']);
            $objPHPExcel->getActiveSheet()->SetCellValue('B' . $rowCount, $element['TMode']);
            $objPHPExcel->getActiveSheet()->SetCellValue('C' . $rowCount, $element['TName']);
            $objPHPExcel->getActiveSheet()->SetCellValue('D' . $rowCount, $element['TDate']);
            $objPHPExcel->getActiveSheet()->SetCellValue('E' . $rowCount, $element['TAmt']);
            $objPHPExcel->getActiveSheet()->SetCellValue('F' . $rowCount, $element['total_sum']);
            $objPHPExcel->getActiveSheet()->SetCellValue('G' . $rowCount, $element['RLAmt']);
            $objPHPExcel->getActiveSheet()->SetCellValue('H' . $rowCount, $element['']);
            $objPHPExcel->getActiveSheet()->SetCellValue('I' . $rowCount, $element['Phone']);
            $rowCount++;
        }

        $objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
        $objWriter->save($fileName);
        // download file
        header("Content-Type: application/vnd.ms-excel");
         redirect(site_url().$fileName);              
    }

这是一个控制器代码：

 <?php

if (!defined('BASEPATH'))
exit('No direct script access allowed');


    class Export extends CI_Model {
    // get mobiles list
    public function mobileList() {

        $data['startdate'] =$this->input->post('SDate');
            $data['enddate'] = $this->input->post('EDate');
            $PName  = $this->input->post('TName');
            $SDate  = $this->input->post('SDate');
            $EDate  = $this->input->post('EDate');

            if($PName = $this->input->post('TName')){


            $query = $this->db->query("SELECT `TAcNo`,`TMode`,`TDate`,`TAmt`,`TName`, COALESCE(SUM(`RLAmt`) ,0) AS `RLAmt`,`Phone` FROM `tipup_payment`  LEFT OUTER JOIN `tipup_receipt` ON `tipup_receipt`.`TRAcNo` = `tipup_payment`.`TAcNo`  AND `TDate` >= '$SDate' AND `TDate` <= '$EDate' LEFT OUTER JOIN `parmaster` ON `parmaster`.`PName` = `tipup_payment`.`TName`  WHERE TName = '$PName' GROUP BY `TAcNo`ORDER BY `TAcNo` ASC");
               return $query->result_array(); 


            //$data['PName']=$query->result_array();
         //$this->load->view('TipUp_Loan\Arrear_Print',$data,FALSE);
        }

        else {
            $query = $this->db->query("SELECT `TAcNo`,`TMode`,`TDate`,`TAmt`,`TName`, COALESCE(SUM(`RLAmt`) ,0) AS `RLAmt`,`Phone` FROM `tipup_payment` LEFT OUTER JOIN `tipup_receipt` ON `tipup_receipt`.`TRAcNo` = `tipup_payment`.`TAcNo`  AND `TDate` >= '$SDate' AND `TDate` <= '$EDate' LEFT OUTER JOIN `parmaster` ON `parmaster`.`PName` = `tipup_payment`.`TName`  GROUP BY `TAcNo` ORDER BY `TAcNo` ASC");
            return $query->result_array();   
            //$data['PName']=$query->result_array();
          //$this->load->view('TipUp_Loan\Arrear_Print',$data,FALSE);
        }


    }
    }
    ?>

这是型号代码：

enter image description here 这是输入视图页面。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。。 enter image description here

这是获取的数据，并在单击“导出”按钮时显示在视图页面中。错误显示我从未上传图片。

我已经在codeiginter网站上下载了phpexcel库文件。

这是链接。...enter link description here

请帮助我解决这个问题。

有很多方法可以解决您的问题。一切都取决于您如何放置（和放置）PHPExcel文件，以及从错误消息中调用该文件，因为我们可以假设PHP在与实际位置不同的位置寻找PHPExcel文件。

YMMV，但这是我的安装。

要输出XLS文件，请从我的模型中获取数据数组（在模型中始终使用return $query->result_array();而不是return $query->result();，除非您以后想将返回的对象转换为数组），然后执行以下操作：< / p>

    $this->excel->setActiveSheetIndex(0);
    $this->excel->getActiveSheet()->setTitle($report);

    $titles = array_keys($data[0]);
    $this->excel->getActiveSheet()->fromArray($titles, NULL, 'A1');
    $this->excel->getActiveSheet()->fromArray($data, NULL, 'A2');

    $filename='output.xls';

    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="'.$filename.'"');
    header('Cache-Control: max-age=0');

    $objWriter = PHPExcel_IOFactory::createWriter($this->excel, 'Excel5');
    $objWriter->save('php://output');

请注意，我正在呼叫$this->excel，该电话来自此代码所在的application/libraries/Excel.php：

<?php
if (!defined('BASEPATH')) exit('No direct script access allowed');  

require_once APPPATH."/third_party/phpexcel/PHPExcel.php";

class Excel extends PHPExcel {
    public function __construct() {
        parent::__construct();
    }
}
?>

从require上的application/third_party/phpexcel/PHPExcel.php可以看到核心PHPExcel文件（由于路由区分大小写，因此请始终注意大小写）。在PHPExcel.php所在的同一级别上，我已将目录包含核心PHPExcel文件-包括autoloader.php-命名为PHPExcel。

这非常简单明了，并且对于使用CI 3.1.x的多个项目来说，对我来说效果很好

如何在Excel中导出数据以及如何使用Codeiginter将PHPExcel文件上传到控制器中？
