如何使用codeigniter將csv文件數據導入到mysql數據庫中？

Question

控制器：partner.php

<?php 
defined('BASEPATH') OR exit('No direct script access allowed'); 
class Partner extends CI_Controller 
{ 
    function __construct() 
    { 
     parent :: __construct(); 
     $this->load->helper(array('form', 'url', 'captcha', 'email')); 
    } 

    public function student() 
    { 
     if($this->input->post('save')) 
     { 
      $client_id[0]['client_id'] = $this->session->userdata('client_id'); 
      $radio = $this->input->post('class'); 
      $client = $client_id[0]['client_id']; 


      $filename = $_FILES['students_list']['name']; 

      $path = FCPATH."resources/imported_file/".$filename; 
      $move=move_uploaded_file($_FILES['students_list']['tmp_name'],$path.$_FILES['students_list']['name']); 
      if($_FILES["students_list"]["size"] > 0) 
      { 
       $file = fopen($path, "r"); 
       while (($importdata = fgetcsv($file))) 
       { 
        $data = array(
         'firstname' => $importdata[0], 
         'email' =>$importdata[1], 
         'phone' =>$importdata[2], 
         'uploaded_date' => date('d-m-y'), 
         'twelfth_year' => date('Y'), 
         'client' => $client[0]['client_id'], 
         'class' => $radio 
        ); 
        $this->db->insert('students',$data); 
       }      
       fclose($file); 
       $this->session->set_flashdata('err_csv', '<p style="color: #87b87f;font-weight: bold;text-align:center;">Data are imported successfully..</p>'); 
      } 
      else 
      { 
       $this->session->set_flashdata('err_csv', '<p style="color: red;font-weight: bold;text-align:center;">Something went wrong..</p>'); 
      } 
     } 
    } 

觀點：

<form method="post" enctype="multipart/form-data"> 
    <input type="file" id="students_list" name="students_list" accept=".csv" class="required"> 
    <input type="submit" name="save" id="save" value="save" class="btn btn-info" /> 
</form> 

我有一個CSV文件，我想csv文件數據導入MySQL數據庫。但是當我上傳csv文件並點擊提交時，它會生成圖像中顯示的錯誤。

那麼，如何刪除這個錯誤？請幫幫我。

謝謝

Answer 1

你應該使用CodeIgniter的文件上傳庫上傳文件，然後使用phpexcel庫導入CSV文件。

Answer 2

試試這個代碼，你可以使用CodeIgniter的上傳庫上傳文件，$ worksheet是一個數組，你所有的數據存儲在該數組中，只是打印工作表。

class Excelreader_controller extends CI_Controller 
{ 

    function __construct() 
    { 
     parent::__construct(); 
     $this->load->library('upload'); 
    } 

    function uploadFile() 
    { 
     $config['upload_path'] = './upload/'; 
     $config['allowed_types'] = 'xls|csv';  

     $this->upload->initialize($config); 
     if($this->upload->do_upload('uploadfile')) 
     { 
      $target_path = "upload/" . basename($_FILES["uploadfile"]["name"]); 
      if(move_uploaded_file($_FILES["uploadfile"]["tmp_name"], $target_path)) { 
       $file=$_FILES["uploadfile"]["name"]; 
       $csv_file="upload/".$file; 
       $worksheet=array(); 
       if (($getfile = fopen($csv_file, "r")) !== FALSE) 
       { 
        $worksheet[] = fgetcsv($getfile, 1000, ","); 
        while (($data = fgetcsv($getfile, 1000, ",")) !== FALSE) 
        { 
         $worksheet[]=$data; 

        } 
       } 

      } 
      else 
      { 
       echo "not uploaded"; 
      } 
     } 
     else 
      echo $this->upload->display_errors(); 

    } 
}
