如何使用codeigniter將CSV文件的數據上傳到mysql

Question

我想使用codeigniter上傳一個csv文件到mysql我試了這個東西很長，但都是靜靜的。我在這裏分享我的代碼..每次我點擊上傳按鈕它不工作。

form.php的

<div class="portlet-body form"> 
    <!-- BEGIN FORM--> 

<?php if($this->session->flashdata('success')== TRUE) ?> 
     <div class="alert alert-success"><?php echo $this->session->flashdata('success'); ?></div> 

    <form name="domestic_csv" action="<?= base_url() ?>controller/add_csv" class="form-horizontal" enctype="multipart/form-data" method="post"> 
     <div class="form-body"> 

      <div class="form-group"> 
      <li class="ui-field"><label for="csvfile">Upload data id file(*only .csv)</label></li> <br> 
       <label class="col-md-3 control-label">Upload Data</label> 
       <div class="col-md-4"> 
        <div class="input-group"> 

         <input type="file" name="userfile" class="form-control" placeholder="Upload Data in CSV format"> </div> 
       </div> 
      </div>    

     <div class="form-actions top"> 
      <div class="row"> 
       <div class="col-md-offset-3 col-md-9"> 
        <button type="submit" class="btn green">Upload</button> 
        <button type="button" class="btn default">Cancel</button> 
       </div> 
      </div> 
     </div> 
     </div> 
    </form> 
    <!-- END FORM--> 
</div> 

Controller.php這樣

public function add_csv() 
{ 
    $data['error']=''; 
    $config['upload_path']='../upload/'; 
    $config['allowed_types']='csv'; 
    $config['max_size']='90000'; 

    $this->load->library('upload',$config); 
    if(!$this->upload->do_upload()){ 
     $data['error']= $this->upload->display_errors(); 
     //$this->load->view('csv',$data); 
     $this->load->view('form',$data);     
    } 
    else{ 
     $file_data = $this->upload->data(); 
     $file_path = '../upload/'.$file_data['userfile']; 

     if($this->csvimport->get_array($file_path)){ 
      $csv_array= $this->csv_import->get_array($file_path); 

      foreach($csv_array as $row){ 
       $insert_data = array('id'=>$row['id'], 
            'name'=>$row['name'], 
            'phone'=>$row['phone'],); 

        $this->main_model->insert_csv($insert_data); 
       } 

       $this->session->set_flashdata('success','The data Inserted!'); 
       redirect('controller/form'); 
      } 

      else{ 
       $data['error'] = 'Error occoured'; 
       $this->load->view('form',$data); 
       } 
     } 
} 

main_model.php

function insert_csv($data){ 
    $this->db->insert('notebook',$data); 
    return 1; 
}

public function add_csv() 
{  
    $filename=$_FILES["file"]["tmp_name"]; 

      if($_FILES["file"]["size"] > 0) 
      { 
       $file = fopen($filename, "r"); 

       while (($emapData = fgetcsv($file, 10000, ",")) !== FALSE) 
        { 
         $insert_data = array('id'=>$row['id'], 
           'name'=>$row['name'], 
           'phone'=>$row['phone'],); 

         $this->main_model->insert_csv($insert_data); 
        } 
       } 
       fclose($file); 

      } 
    }
