2个Codeigniter文件批量上传控制器写法例子

例子一：

public function multiple_uploads() {
  //载入所需类库
  $this->load->library('upload');
  
  //配置上传参数
  $upload_config = array(
      'upload_path'  => '',
      'allowed_types' => 'jpg|png|gif',
      'max_size'   => '500',
      'max_width'   => '1024',
      'max_height'  => '768',
  );
  $this->upload->initialize($upload_config);
    
  //循环处理上传文件
  foreach ($_FILES as $key => $value) {
    if (!empty($key['name'])) {
      if ($this->upload->do_upload($key)) {
 //上传成功
 print_r($this->upload->data());
      } else {
 //上传失败
 echo $this->upload->display_errors();
      }
    }
  }
}

例子二：

function upload() {
    $config['upload_path'] = './uploads/'; 
    
    $config['allowed_types'] = 'gif|jpg|png';
    
    $config['max_size'] = '1024';
    $config['max_width'] = '1024';
    $config['max_height'] = '768';

    $config['file_name'] = time(); //文件名不使用原始名
    $this->load->library('upload', $config);
    if(!$this->upload->do_upload()) {
 echo $this->upload->display_errors();
    }else{

$data['upload_data']=$this->upload->data(); //文件的一些信息
$img=$data['upload_data']['file_name']; //取得文件名

echo $img."
";

foreach($data['upload_data'] as $item => $value){
echo $item.":".$value."
";

      }

    }
}
