使用codeigniter上传时"没有选择要上传的文件"

Question

我试图上传图像,但它总是给我"你没有选择要上传的文件."

我的控制器

function add()
{

        $thedate=date('Y/n/j h:i:s');
        $replace = array(":"," ","/");
        $newname=str_ireplace($replace, "-", $thedate);

        $config['upload_path'] = './upload/';
        $config['allowed_types'] = 'gif|jpg|png|jpeg';
        $config['file_name']=$newname;
        $config['max_size'] = '100';
        $config['max_width']  = '1024';
        $config['max_height']  = '768';

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

        $this->form_validation->set_rules('title','title','trim|required');
        $this->form_validation->set_rules('description','Description','trim|required');
        $image1=$this->input->post('image');


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

            $this->addview();   

            return false;

        }


      if (!$this->upload->do_upload($image1)) {

        $error = array('error' => $this->upload->display_errors());
        $this->load->view('upload_error', $error);


         }

       else {
        $mage=$this->upload->do_upload($image1);

            $data =array(
            'title'=>$this->input->post('title'),
            'descrip'=>$this->input->post('description'),

            'image' => $mage['file_name']

    );  


            $this->load->model('member_functions');

            $q=$this->member_functions->insert($data);
    }}

设置了所有文件要求和文件权限,但我仍然得到了那个错误.有人可以告诉我,我做错了什么

Answer 1

$this->upload->do_upload()函数的参数应该是表单字段的名称.(如果你不使用参数调用它将userfile被使用).在你的情况下,它似乎应该是'形象'.代替:

$image1=$this->input->post('image');

它应该是:

$image1='image';

Answer 2

• 查看页面

表格标签应包含enctype="multipart/form-data".
即 <form action='' method=''enctype="multipart/form-data> <input type='file' name='field_name'/>

• 调节器

并且在控制器上传代码中应该$this->upload->do_upload("field_name")
和jsut一样通过打印来检查文件是否到达服务器端

print_r($_FILES);

如果你得到空数组,那么请确保客户端代码是正确的.
