我是codeigniter的新手，我正在尝试制作一个更新个人资料的表单。它以前有用，但现在它已经不存在了。 我在视图中改变了一些东西，它停止了工作。我把它改回原来的状态，但它已经不再适用了。我花了半天的时间试图让它再次运作，但我失败了。
也许我不知道你们能看到什么。至少我希望如此。
这是我的观点：
<?php echo form_open_multipart('Gids/do_upload');?>
<img width="200px" src="<?php echo base_url()."uploads/".$profile[0]['image']; ?>" alt=""/>
<label for="">Uploade new picture:</label><input type="file" name="userfile" size="20" value="128.jpg" >
<input style="display: none" id="image" name="image" type="text" value="<?php echo "profile_picture".$_SESSION['id'].".jpg"; ?>"/>
<label for="naam">Naam:</label><input id="naam" name="naam" type="text" value="<?php echo $profile[0]['naam']; ?>"/>
<label for="voornaam">Voornaam:</label><input id="voornaam" name="voornaam" type="text" value="<?php echo $profile[0]['voornaam']; ?>"/>
<label for="email">Gebruikersnaam:</label><input id="gebruikersnaam" name="gebruikersnaam" type="text" value="<?php echo $profile[0]['gebruikersnaam']; ?>"/>
<label for="email">Email:</label><input id="email" name="email" type="text" value="<?php echo $profile[0]['email']; ?>"/>
<label for="opleiding">Opleiding:</label><input id="opleiding" name="opleiding" type="text" value="<?php echo $profile[0]['opleiding']; ?>"/>
<label for="school">School:</label><input id="school" name="school" type="text" value="<?php echo $profile[0]['school']; ?>"/>
<label for="wachtwoord">Wachtwoord:</label><input id="wachtwoord" name="wachtwoord" type="text" />
<label for="typeAgain">Type Opnieuw:</label><input id="typeAgain" type="text" />
<label for="over">Over mezelf:</label><textarea name="over" id="over" cols="30" rows="10"><?php echo $profile[0]['over']?></textarea>
<input type='text' style="display: none" name='student_id' value="<?php echo $profile[0]['student_id']?>"/>
<button class="btn btn-default" id="changeprofile" type="submit">Wijzigingen opslaan</button>
</form>
正如您所看到的，还有一个图片上传 这是我的控制器：
function do_upload()
{
$this->load->model("Gids_model",'',true);
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '1000';
$config['file_name'] = 'profile_picture'.$_SESSION['id'].'.jpg';
$config['overwrite'] = 'TRUE';
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error_upload = array('error' => $this->upload->display_errors());
redirect('Gids/datum', $error_upload);
}
else
{
$this->Gids_model->update_profile($this->input->post('student_id'), $this->input->post('voornaam'), $this->input->post('naam'), $this->input->post('email'), $this->input->post('wachtwoord'), $this->input->post('opleiding'), $this->input->post('school'), $this->input->post('over'), $this->input->post('image'), $this->input->post('gebruikersnaam'));
//$e = $this->input->post('student_id');
$data_upload = array('upload_data' => $this->upload->data());
redirect('Gids/datum', $data_upload);
}
}
这是我的模特：
public function update_profile($id, $voornaam, $naam, $email, $wachtwoord, $opleiding, $school, $over, $image, $gebruikersnaam){
$data = array(
'student_id' => $id,
'voornaam' => $voornaam,
'naam' => $naam,
'email' => $email,
'wachtwoord' => $wachtwoord,
'opleiding' => $opleiding,
'school' => $school,
'over' => $over,
'image' => $image,
'gebruikersnaam' => $gebruikersnaam
);
$this->db->where('student_id', $id);
$this->db->update('tbl_student', $data);
}
form_open_multipart('Gids/do_upload')是什么，我从教程中获得了使用codeigniter上传图像。
答案 0 :(得分：0)
这是我试过的
public function do_upload() {
$this->load->model("Gids_model",'',true);
// load library or you can do it with autoloading
// feature of CI
$this->load->library('upload');
// make sure that the folder uploads is created
// at the root directory of the project
$config = array(
'upload_path' => './uploads',
'allowed_types' => 'jpg|jpeg|JPG|JPEG|png',
'max_size' => '1000',
'file_name' => 'profile_picture.jpg',
'overwrite' => true
);
// use initialize instead
$this->upload->initialize($config);
if ( ! $this->upload->do_upload('userfile'))
{
$error_upload = array('error' => $this->upload->display_errors());
// you can check the errors here by using var_dump();
// just uncomment the the line below
// var_dump($this->upload->display_errors());die();
redirect('Gids/datum', $error_upload);
}
else
{
$this->Gids_model->update_profile($this->input->post('student_id'), $this->input->post('voornaam'), $this->input->post('naam'), $this->input->post('email'), $this->input->post('wachtwoord'), $this->input->post('opleiding'), $this->input->post('school'), $this->input->post('over'), $this->input->post('image'), $this->input->post('gebruikersnaam'));
//$e = $this->input->post('student_id');
$data_upload = array('upload_data' => $this->upload->data());
redirect('Gids/datum', $data_upload);
}
}

我试过这个并希望它有所帮助：
控制器：
public function upload_profile() {
$input = $this->input->post();
$config['upload_path'] = './uploads/profile_pics/'; //path were I save the uploaded profile pics
$config['allowed_types'] = 'gif|jpg|png'; // allowed types that is mention
//size of the picture by default
$config['max_size'] = '100';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$config['overwrite'] = true;
$this->load->library('upload', $config);
// display error if the picture is not on the config (sample bmp)
if ( ! $this->upload->do_upload())
{
$error = $this->upload->display_errors(); // display the errors
$data['upload_error'] = $error;
if($this->session->userdata('account_id') != null) { // if there is an account
$this->load->model('profile'); //model
$this->load->model('account'); //model
$data['user'] = $this->profile->get_profile($this->session->userdata('account_id')); //get_profile is a function in model
$data['account'] = $this->account->get_account($this->session->userdata('account_id')); //get_account is a function in model
$data['view'] = 'users/settings';
$data['title'] = "User's Settings";
$data['error'] = $error;
$this->load->view('masterpage', $data);
} else {
redirect(base_url('index.php/qablog/login'));
}
}
else
{
//if no error
$data = $this->upload->data();
$updateProfile = array(
'profile_pic' => $data['file_name']
);
$this->load->model('profile');
$this->profile->update_profile($this->session->userdata('account_id'), $updateProfile); // update the profile of the user
redirect(base_url('index.php/users/profile'));
}
}
模型get_profile（）：
public function get_profile($profile_id)
{
$this->db->select()->from('profile_tbl')->where('profile_id', $profile_id);
$query = $this->db->get();
return $query->first_row('array');
}
模型update_profile（）：
public function update_profile($profile_id, $data)
{
$this->db->where('profile_id', $profile_id);
$this->db->update('profile_tbl', $data);
return $this->db->affected_rows();
}
模型get_account（）：
public function get_account($account_id)
{
$this->db->select()->from('account_tbl');
$this->db->where('account_id', $account_id);
$query = $this->db->get();
return $query->result_array();
}
