Question

嗨我得到PHPExcel_IOFactory未找到错误的下面提到的行

$objReader= PHPExcel_IOFactory::createReader('Excel2007');

//控制器

function ExcelDataAdd() 
{  
     $configUpload['upload_path'] ='./uploads/';
     $configUpload['allowed_types'] = 'xls|xlsx|csv';
     $configUpload['max_size'] = '5000';
     $this->load->library('upload', $configUpload);
     $this->upload->do_upload('userfile');  
     $upload_data = $this->upload->data();  
     $file_name = $upload_data['file_name']; 
     $extension=$upload_data['file_ext'];

      $objReader= PHPExcel_IOFactory::createReader('Excel2007');
      $objReader->setReadDataOnly(true);
      $objPHPExcel=$objReader->load('./uploads/'.$file_name);     
      $totalrows=$objPHPExcel->setActiveSheetIndex(0)->getHighestRow();   
      $objWorksheet=$objPHPExcel->setActiveSheetIndex(0);      
      for($i=2;$i<=$totalrows;$i++)
      {
          $FirstName= $objWorksheet->getCellByColumnAndRow(0,$i)->getValue();     
          $LastName= $objWorksheet->getCellByColumnAndRow(1,$i)->getValue(); 

          $this->Excel_export_model->Add_stud($data_stud);     
      }
      unlink('./uploads/'.$file_name);                     
      redirect("Welcome");
    }

请告诉我哪里出错了

Answer 1

我找到了一个解决方案，我没有在功能中加载模型。下面提到的功能正常工作

function ExcelDataAdd() 
{  
     $configUpload['upload_path'] ='./uploads/';
     $configUpload['allowed_types'] = 'xls|xlsx|csv';
     $configUpload['max_size'] = '5000';
     $this->load->library('upload', $configUpload);
     $this->upload->do_upload('userfile');  
     $upload_data = $this->upload->data();  
     $file_name = $upload_data['file_name']; 
     $extension=$upload_data['file_ext'];

      $objReader= PHPExcel_IOFactory::createReader('Excel2007');
      $objReader->setReadDataOnly(true);
      $objPHPExcel=$objReader->load('./uploads/'.$file_name);     
      $totalrows=$objPHPExcel->setActiveSheetIndex(0)->getHighestRow();   
      $objWorksheet=$objPHPExcel->setActiveSheetIndex(0);      
      for($i=2;$i<=$totalrows;$i++)
      {
          $FirstName= $objWorksheet->getCellByColumnAndRow(0,$i)->getValue();     
          $LastName= $objWorksheet->getCellByColumnAndRow(1,$i)->getValue(); 
          $data_stud=array('optra_id'=>$optra_id, 'student_fname'=>$student_fname);print_r($data_stud);
              $this->load->model("Excel_export_model");
          $this->Excel_export_model->Add_stud($data_stud);     
      }
      unlink('./uploads/'.$file_name);                     
      redirect("Welcome");
    }

Answer 2

试试这个

$this->load->library('PHPExcel');
$objPHPExcel = PHPExcel_IOFactory::load($_FILES['file']['tmp_name']);
$sheet1 = $objPHPExcel->getSheet(0)->toArray(null,true,true,true);
echo "<pre>";print_r($sheet1);die;

其中file是文件标签的名称，如<input type="file" name="file">

请从此链接下载PHPExcel并粘贴到application/library/文件夹中
