在codeigniter中不成功提交表單之後無法保留值

Question

我希望在表單未正確提交的情況下，用戶輸入的值不會丟失。形式是建立在笨

查看

<?php echo form_open_multipart('user/add_data'); ?> 
    <?php 
     $data = array(
      'type'=>'text', 
      'name'=>'name', 
      'class'=>'form-control', 
      'required' => 'required', 
      'value' => set_value('name') 
     ); 
    ?> 
    <?php echo form_input($data); ?> 

    <?php 
     $data = array(
      'type'=>'file', 
      'name'=>'userfile', 
      'class'=>'fileinput btn-info', 
      'id'=>'filename3', 
      'data-filename-placement'=>'inside', 
      'style' => 'margin-left: 330px', 
      'title'=>'If any document upload here (* XLS | DOC | PDF | DOCX | XLSX)' 
     ); 

     echo form_upload($data); 
    ?> 

    <?php 
     $data = array(
      'type'=>'submit', 
      'class'=>'btn btn-primary pull-right', 
      'name'=>'submit', 
      'content'=>'Submit' 
     ); 
     echo form_button($data); 
     ?> 


<?php echo form_close(); ?> 

控制器

public function add_requirement_data() { 
    $config['upload_path'] = './request/'; 
    $config['allowed_types'] = 'xls|xlsx|doc|docx|pdf'; 
    $config['max_size'] = 9000000; 
    $config['max_width'] = 1024; 
    $config['max_height'] = 768; 
    $config['encrypt_name'] = TRUE; 

    $this->load->library('upload', $config); 

    if (!$this->upload->do_upload('userfile')) 
     { 
     $data = array('upload_data' => $this->upload->data()); 
     if ($data['upload_data']['file_size'] == '0') 
      { 
      $this->session->set_flashdata('req_msg', 'Cannot Upload Empty File'); 
      redirect('user/requirement'); 
      } 
     else 
      { 
      if ($this->um->create_requirement_nofile($instanthire_main_id)) 
       { 
       $this->session->set_flashdata('req_msg', 'Requirment raised successfully'); 
       redirect('user/requirement'); 
       } 
      } 
     } 
} 

誰能告訴如何保留笨形式

值通過使用會話
讓我們考慮您的名稱輸入標籤
在您的瀏覽器中

<?php 
     $data = array(
      'type'=>'text', 
      'name'=>'name', 
      'class'=>'form-control', 
      'required' => 'required', 
      'value' => $this->session->userdata('name') 
     ); 
    ?> 

而在你的控制器，

$this->session->set_userdata('name',$this->input->post('name')); 
if ($data['upload_data']['file_size'] == '0') 
{ 
    $this->session->set_flashdata('req_msg', 'Cannot Upload Empty File'); 
    redirect('user/requirement'); 
} 
else 
{ 
    if ($this->um->create_requirement_nofile($instanthire_main_id)) 
    { 
     $this->session->unset_userdata('name'); 
     $this->session->set_flashdata('req_msg', 'Requirment raised successfully'); 
     redirect('user/requirement'); 
    } 
}
