CodeIgniter - 文件上传需要验证 [英] CodeIgniter - File upload required validation

问题描述

我有2个文本字段和1个文件上传，都是必需的。一切都工作，当我只需要文本字段，但是当我需要文件上传验证错误仍然说，一个文件是必需的，即使我选择一个。任何人都知道我做错了什么？非常感谢。

//查看

 < ;? php echo form_open_multipart（'add'）; > 
 
< fieldset> 
< input type =textname =name/>< br> 
< input type =textname =code/>< br> 
< input type =filename =userfile/>< br>< br> 
< input type =submitvalue =Add/> 
< / fieldset> 
 
<？php echo form_close（）; > 
  

// controller

  public function add（）{
 
 $ this-> form_validation-> set_rules（'name'，'Name'，'required'）; 
 $ this-> form_validation-> set_rules（'code'，'Code'，'required'）; 
 // $ this-> form_validation-> set_rules（'userfile'，'Document'，'required'）; 
 //当上面的行是活动的上传不通过
 
 if（$ this-> form_validation-> run（）== FALSE）{
 
 $ data ['page_view'] = $ this-> page_view; 
 $ data ['page_title'] = $ this-> page_title; 
 $ this-> load-> view（'template'，$ data）; 
} 
 else 
 {
 $ this-> load-> library（'upload'）; 
 
 if（！empty（$ _ FILES ['userfile'] ['name']））
 {
 $ config ['upload_path'] ='./uploads/' ; 
 $ config ['allowed_types'] ='gif | jpg | png | jpeg'; 
 
 $ this-> upload-> initialize（$ config）; 
 
 if（$ this-> upload-> do_upload（'userfile'））
 {
 $ img = $ this-> upload-> data ; 
 $ file_name = $ img ['file_name']; 
 
 $ name = $ this-> input-> post（'name'）; 
 $ code = $ this-> input-> post（'code'）; 
 
 $ this-> load-> model（'create'，'create_model'）; 
 $ this-> create_model-> create_entry（$ name，$ code，$ file_name）; 
 
 $ data ['page_view'] = $ this-> page_view; 
 $ data ['page_title'] = $ this-> page_title; 
 $ this-> load-> view（'template'，$ data）; 
} 
 else 
 {
 echo $ this-> upload-> display_errors（）; 
 
} 
} 
} 
} 
  

我改变了

$

b $ b

  $ this-> form_validation-> set_rules（'name'，'Name'，'trim | required'）; 
 $ this-> form_validation-> set_rules（'code'，'Code'，'trim | required'）; 
 $ this-> form_validation-> set_rules（'userfile'，'Document'，'required'）; 
  

至

  $ this-> form_validation-> set_rules（'name'，'Name'，'trim | required'）; 
 $ this-> form_validation-> set_rules（'code'，'Code'，'trim | required'）; 
 if（empty（$ _ FILES ['userfile'] ['name']））
 {
 $ this-> form_validation-> set_rules（'userfile'，'Document' '需要'）; 
} 
  

I have 2 text fields and 1 file upload that are all required. Everything works when I require just the text fields, but when I require the file upload the validation error stays saying that a file is required, even though I selected one. Anyone know what I am doing wrong? Many thanks in advance.

//view

<?php echo form_open_multipart('add'); ?>

<fieldset>
    <input type="text" name="name" /><br>
    <input type="text" name="code" /><br>
    <input type="file" name="userfile" /><br><br>
    <input type="submit"value="Add" />
</fieldset>

<?php echo form_close(); ?>

//controller

public function add() {

    $this->form_validation->set_rules('name', 'Name', 'required');
    $this->form_validation->set_rules('code', 'Code', 'required');
    //$this->form_validation->set_rules('userfile', 'Document', 'required');
    //when the above line is active the upload does not go through

    if ($this->form_validation->run() == FALSE) {

        $data['page_view'] = $this->page_view;
        $data['page_title'] = $this->page_title;
        $this->load->view('template', $data);
    }
    else
    {
        $this->load->library('upload');

        if (!empty($_FILES['userfile']['name']))
        {
            $config['upload_path'] = './uploads/';
            $config['allowed_types'] = 'gif|jpg|png|jpeg';     

            $this->upload->initialize($config);

            if ($this->upload->do_upload('userfile'))
            {
                $img = $this->upload->data();
                $file_name = $img['file_name'];

                $name = $this->input->post('name');
                $code = $this->input->post('code');

                $this->load->model('create', 'create_model');
                $this->create_model->create_entry($name, $code, $file_name);

                $data['page_view'] = $this->page_view;
                $data['page_title'] = $this->page_title;
                $this->load->view('template', $data);
            }
            else
            {
                echo $this->upload->display_errors();

            }
        }
    }
}

解决方案

I found a solution that works exactly how I want.

I changed

$this->form_validation->set_rules('name', 'Name', 'trim|required');
$this->form_validation->set_rules('code', 'Code', 'trim|required');
$this->form_validation->set_rules('userfile', 'Document', 'required');

To

$this->form_validation->set_rules('name', 'Name', 'trim|required');
$this->form_validation->set_rules('code', 'Code', 'trim|required');
if (empty($_FILES['userfile']['name']))
{
    $this->form_validation->set_rules('userfile', 'Document', 'required');
}
