在 Codeigniter 中上传图片

Question

我是 Codeigniter 的新手，我在使用图片上传功能时遇到了问题。错误提示 - 您没有 select 要上传的文件。谁能检查我的代码并告诉我该怎么做？

这是我的控制器

这是我处理数据的控制器。

public function add_data() {
    $this->load->view('admin/header.php');

    $this->load->library('form_validation');

    $this->form_validation->set_rules('name', 'name', 'required');
    $this->form_validation->set_rules('price', 'price', 'required');

    $this->load->helper(array('form', 'url'));
    if ($this->form_validation->run() == TRUE)
    {
        $this->load->view('admin/add_view.php');
        $config['upload_path'] = './files/';
        $config['allowed_types'] = 'jpg';
        $this->load->library('upload', $config);
        $this->upload->do_upload('picture');
        $this->upload->data();

        $data = array(
            'name' => $this->input->post('name'),
            'info' => $this->input->post('info'),
            'gorod' => $this->input->post('gorod'),
            'price' => $this->input->post('price'),
            'amount' => $this->input->post('amount'),
            'age' => $this->input->post('age'),
            'status' => $this->input->post('status'),
            'minbal' => $this->input->post('minbal'),
            'contacts' => $this->input->post('contacts'),
            'email' => $this->input->post('email'),
            'alias' => $this->input->post('alias'),
            'filename' => $this->input->post('picture')
        );
        $this->Adminmodel->add_record($data);
    }
    else
    {
        $this->load->view('admin/formnotsuccess');
    }
}

Answer 1

你不见了

enctype="multipart/form-data" 形式

Read php file upload

And Upload code should be like bellow. Its easy to track your errors

if(!$this->upload->do_upload()) # do_upload('picture');
{
    echo  $this->upload->display_errors();
}
else
{
    $data =  $this->upload->data();
    print_r($data);
}
