[英]Codeigniter: Upload/Save Image to Database
我正在尝试在Codeigniter项目上创建用户个人资料编辑表单,并能够上传个人资料图片。 我希望当用户单击“提交”按钮时允许上传完成。 我的表单没有问题(没有错误),但是在我设置的上载文件夹中没有看到任何图像。 任何帮助上载工作的帮助将不胜感激。
控制器(用户编辑/将值插入数据库)
public function update_edit($id)
{
$config['upload_path'] = '/uploads/profilepics';
$config['allowed_types'] = 'gif|jpg|png|jpeg';
$config['max_size'] = 250;
$this->load->library('upload', $config);
$this->upload->do_upload('profile_img_path');
$data_upload_files = $this->upload->data();
$image = $data_upload_files[full_path];
//input data
$data = array(
'user_name' => $this->input->post('user_name'),
'email' => $this->input->post('email'),
'first_name' => $this->input->post('first_name'),
'last_name' => $this->input->post('last_name'),
'city' => $this->input->post('city'),
'country' => $this->input->post('country'),
'description' => $this->input->post('description'),
'date_edited' => $this->input->post('today'),
'profile_img_path' => $image
);
$this->user_model->update_account($id,$data);
//send a confirmation of user account update
redirect('/');
}
控制器访问表格
public function update_account()
{
$id = $this->uri->segment(3);
$data['user_profile'] = $this->user_model->get_user_profile($id);
//only profile owner can access
if (!$this->uri->segment(3))
{
redirect('404');
}
if ($this->is_logged_in())
{
if ($this->is_logged_user())
{
//update views
$this->load->view('components/top');
$this->load->view('interact/form/user/edit',$data);
$this->load->view('components/bottom');
}

redirect('403');
}

redirect('403');

您应该在表单中包含enctype
enctype="multipart/form-data"
<form id="edit_form" class="form-horizontal" method="post" action="<?php echo base_url() . "users/update_edit/" . $user->user_id; ?>" enctype="multipart/form-data">
可以在加载库之后尝试此代码。
$this->upload->initialize($config);
if (!$this->upload->do_upload('profile_img_path')) {
$error = array('error' => $this->upload->display_errors());
echo $error['error'];
}
让我们知道您遇到的确切错误。
$config['upload_path'] = '/uploads/profilepics';
指向文件系统中的一个文件夹,您可能对该文件夹没有写权限。 使用相对路径,例如$config['upload_path'] = './uploads/profilepics';
( ./
是当前目录)。 另外,请确保该文件夹存在,并且您对该文件夹具有写权限。
