Php 上传图像并在codeigniter中插入文本
我正试图上传一个带有标题和描述的图片。我的图像上传和文本输入分开工作,文本和图像路径也被插入到数据库中,但我仍然不知道如何将两者结合起来 我使用了中给出的指南Php 上传图像并在codeigniter中插入文本,php,codeigniter,insert,image-uploading,Php,Codeigniter,Insert,Image Uploading,我正试图上传一个带有标题和描述的图片。我的图像上传和文本输入分开工作,文本和图像路径也被插入到数据库中,但我仍然不知道如何将两者结合起来 我使用了中给出的指南 有人能告诉我如何将一些文本字段与图像上载表单一起插入sql数据库吗?基本上,只需将图像上载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("d
有人能告诉我如何将一些文本字段与图像上载表单一起插入sql数据库吗?基本上,只需将图像上载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
并在控制器中添加后期读取:
// 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,以便在数据库中输入数据。Hello@Woxxy回答得很好。但是,如果图像上传是可选的更新怎么办。在这种情况下该怎么办?
// 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);
}
}
