Question

我想通过以下表单上传图片：

<?php echo form_open_multipart('posts/create'); ?>
  <div class="form-group">
    <label>Title</label>
    <input type="text" class="form-control" name="title" placeholder="Add Title" required>
  </div>

  <div class="form-group">
    <label>Body</label>
    <textarea id="editor1" class="form-control" name="body" placeholder="Add Body" required></textarea>
  </div>

  <div class="form-group">
      <label>Category</label>
      <select name="category_id" class="form-control">
          <?php foreach($categories as $category): ?>
            <option value="<?php echo $category['id']; ?>"><?php echo $category['name']; ?></option>
          <?php endforeach; ?>
      </select>
  </div>

  <div class="form-group">
      <label>Upload Image</label>
      <input type="file" name="userfile" size="20">
  </div>
  <button type="submit" class="btn btn-default">Submit</button>
</form>

当我发送信息时，我会检查POST请求是否具有正确的数据。不是。

它告诉我所有输入都希望文件输入...

这是控制器，称为Posts，而函数称为create。

public function create() {
  $data['title'] = 'Create post';
  $data['categories'] = $this->post_model->get_categories();

  $this->form_validation->set_rules('title', 'Title', 'required');
  $this->form_validation->set_rules('body', 'Body', 'required');

  if (!$this->form_validation->run()) {
    $this->load->view('templates/header');
    $this->load->view('posts/create', $data);
    $this->load->view('templates/footer');
  } else {
    // Upload image
    $config['upload_path'] = 'assets/images/posts';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = 2048;
    $config['max_width'] = 2000;
    $config['max_height'] = 2000;

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

    # Here's where I print the request.
    print_r($_POST);
    if (!$this->upload->do_upload('userfile')) {
      $errors = array('error' => $this->upload->display_errors());
      $post_image = 'noimage.jpg';
    } else {
      $data = array('upload_data' => $this->upload->data());
      $post_image = $_FILES['userfile']['name'];
    }
    echo $post_image;

    /* $this->post_model->create_post($post_image);
    redirect('posts'); */
  }
}

autoloader.php配置正确...

$autoload['helper'] = array('url', 'form', 'text');

如果有人需要整个项目，请here you go

我正在使用Docker运行它，您可以使用docker-compose up --build对其进行测试。

Answer 1

我已经测试了您的代码，并且工作正常，这是var_dump($_FILES);的结果：

["userfile"]=>
array(5) {
    ["name"]=>
    string(9) "image.jpg"
    ["type"]=>
    string(10) "image/jpeg"
    ["tmp_name"]=>
    string(23) "C:\xampp\tmp\phpB54.tmp"
    ["error"]=>
    int(0)
    ["size"]=>
    int(493443)
}

没问题。

但请记住，您应该给$config['upload_path']一个相对路径或一个绝对路径，因此您可以考虑使用此$config['upload_path'] = './assets/images/posts';或最好使用$config['upload_path'] = FCPATH'assets/images/posts'; < / p>

Answer 2

编辑控制器Posts.php并添加：

SessionPool

是解决方案。

form_open_multipart不上传文件
