我试图上传带有标题和描述的图像以及图片上传.我的图像上传和文本输入分开工作,文本和图像路径也插入到数据库但我仍然无法想象如何将两者结合使用

我使用了http://codeigniter.com/user_guide/libraries/file_uploading.html中给出的指南

function do_upload()
    {
        $config['upload_path'] = './uploads/';
        $config['allowed_types'] = 'gif|jpg|png';
        $config['max_size'] = '100';
        $config['max_width']  = '1024';
        $config['max_height']  = '768';

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

        if ( ! $this->upload->do_upload())
        {
            $error = array('error' => $this->upload->display_errors());

            $this->load->view('upload_form',$error);
        }
        else
        {
            $data = array('upload_data' => $this->upload->data());

            $this->load->view('upload_success',$data);
        }
    }

谁能告诉我如何将一些文本字段和图像上传表单一起插入到sql数据库中？

解决方法

基本上,只需将图像上传输入放在相同的表单中,如：

// view
echo form_open_multipart('controller_name/do_upload');
echo form_input("title","");
echo form_input("description","");
echo form_upload("userfile");
echo form_close

并在控制器中添加POST读数：

// controller
function do_upload()
{
    $config['upload_path'] = './uploads/';
    $config['allowed_types'] = 'gif|jpg|png';
    $config['max_size'] = '100';
    $config['max_width']  = '1024';
    $config['max_height']  = '768';

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

    // validate the POST data 
    // http://codeigniter.com/user_guide/libraries/form_validation.html
    $this->form_validation->set_rules('title','Title','trim|required');
    $this->form_validation->set_rules('description','Description','trim|required')

    if ($this->form_validation->run() == FALSE)
    {   
        // failed validation
        $this->load->view('myform');

        // quit here
        return false;
    }

    if ( ! $this->upload->do_upload())
    {
        // no file uploaded or failed upload
        $error = array('error' => $this->upload->display_errors());
        $this->load->view('upload_form',$error);
    }
    else
    {
        // success
        $data = array('upload_data' => $this->upload->data());
        $title = $this->input->post('title');
        $description = $this->input->post('description');

        // a model that deals with your image data (you have to create this)
        $this->your_upload_model->add($title,$description,$data["file_name"]);

        $this->load->view('upload_success',$data);
    }
}

您还需要制作一个合适的模型来输入数据库中的数据.
