我目前正在制作一个模块，用户可以在其中将包含一些详细信息的图像上传到数据库，但它不起作用，甚至验证都没有显示我已经为图像创建了上传目录
Controller :
public function do_upload() {
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1024';
$config['max_width'] = '1024';
$config['max_height'] = '1024';
$config['new_image'] = './uploads/';
$config['overwrite'] = TRUE;
$this->load->library('upload', $config);
$this->form_validation->set_rules('type', 'Type', 'required');
$this->form_validation->set_rules('school', 'School', 'required');
$this->form_validation->set_rules('email', 'Email', 'required|valid_email');
if (!$this->upload->do_upload() || !$this->form_validation->run()) {
$error = array('error' => $this->upload->display_errors());
redirect('user/payment');
} else {
$data = $this->upload->data();
$this->thumb($data);
$file = array(
'img_name' => $data['raw_name'],
'thumb_name' => $data['raw_name'] . '_thumb',
'ext' => $data['file_ext'],
'type' => $this->input->post('type'),
'school' => $this->input->post('school'),
'email' => $this->input->post('email'),
);
$data = array('upload_data' => $this->upload->data());
$this->user_model->add_image($file);
// redirect('user/home_register');
$this->load->view('user/upload_success');
}
}
public function thumb($data) {
$config['image_library'] = 'gd2';
$config['source_image'] = $data['full_path'];
$config['create_thumb'] = TRUE;
$config['maintain_ratio'] = TRUE;
$config['width'] = 275;
$config['height'] = 250;
$config['new_image'] = './thumbs/';
$this->load->library('image_lib', $config);
$this->image_lib->resize();
}

模型
function add_image($data) {
$this->db->set('payment_date', 'NOW()', FALSE);
$this->db->insert('payment', $data);
}
我在数据库中有 8 个字段id(自增),payment_data,type,school,email,img_name,thumb_name and ext
最佳答案
尝试将 pic 字段名称添加到
$this->upload->do_upload('pic')
并将 Raw Name 更改为 file_name
关于database - 上传带有图像的数据在 codeigniter 中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35076450/

我有以下正则表达式 /[a-zA-Z0-9_-]/ 当字符串只包含从 a 到z 大小写、数字、_ 和 -。 我的代码有什么问题？ 能否请您向我提供一个简短的解释和有关如何修复它的代码示例？ //var
