I'm use Grocery CRUD. I create custom button using add_action.
The button for change data to 0. So, after click the button database update column to 0.
Controller:
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Attendance extends Admin_Controller
{
public function __construct()
{
parent::__construct();
$this->load->library('form_builder');
}
public function attendance($visitor_id)
{
$attendance_status = array(
'attendance_status' => 0
);
$update = $this->Attendace_model->update_attendance_status($visitor_id,$attendance_status);
if($update)
{
$this->load->view('Attendance');
}
else
{
alert("error");
}
}
}
Model :
<?php
class Attendance_model extends MY_Model {
function __construct()
{
parent::__construct();
}
function update_attendance_status($visitor_id,$attendance_status)
{
$this->db->where('id', $visitor_id);
$this->db->update('invitation_codes', $attendance_status);
}
}
What code to use in function for update the data to 0/
Controller:
public function attendance($visitor_id)
{
$attendance_status = array(
'attendance_status' => 0
);
$update = $this->YOUR_MODEL_NAME- >update_attendance_status($visitor_id,$attendance_status);
if($update)
{
return true;
}
else
{
return false;
}
}
Model :
public function update_attendance_status($visitor_id,$attendance_status)

I'm trying to get the comments of teacher and principal to show up in view, all to no avail.
This is a school web app where parents get to view the results of their respective children. Just below the scores is the teacher's and principal comments.
Now, these comments show up in students' view but I'm having a hard time making it show up on the parents' view.
This is the model:
Comment_model.php
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Comment_model extends CI_Model {
public function __construct() {
parent::__construct();
$this->current_session = $this->setting_model->getCurrentSession();
$this->current_session_name = $this->setting_model->getCurrentSessionName();
$this->start_month = $this->setting_model->getStartMonth();
}
public function TeacherComment($data)
{
$this->db->insert('teacher_comments', $data);
return $query = $this->db->affected_rows();
}
public function UpdateTeacherComment($data, $id)
{
$this->db->where('id', $id);
$this->db->update('teacher_comments', $data);
return $query = $this->db->affected_rows();
}
public function GetTeacherComment($student_id, $session_id)
{
$this->db->select('*');
$this->db->where('student_id', $student_id);
$this->db->where('session_id', $session_id);
return $this->db->get('teacher_comments')->row();
}
public function PrincipalComment($data)
{
$this->db->insert('principal_comments', $data);
return $this->db->affected_rows();
}
public function UpdatePrincipalComment($data, $id)
{
$this->db->where('id', $id);
$this->db->update('principal_comments', $data);
return $query = $this->db->affected_rows();
}
public function GetPrincipalComment($student_id, $session_id)
{
$this->db->select('*');
$this->db->where('student_id', $student_id);
$this->db->where('session_id', $session_id);
return $this->db->get('principal_comments')->row();
}
}
The Controller I'm battling with:
$data['teacher_comment'] = $this->Comment_model->GetTeacherComment($id, $student_session_id);
$data['principal_comment'] = $this->Comment_model->GetPrincipalComment($id, $student_session_id);
How do I properly put it in function?
The view:
<span> CLASS TEACHER'S REMARK:
<u style="text-transform: uppercase;"><?php echo $teacher_comment->teacher_comment; ?> </u>
</span><br>
<br>
<span>PRINCIPAL REMARK:
<u style="text-transform: uppercase;"><?php echo $principal_comment->principal_comment; ?></u>
</span>
Let suppose this is your controller file.
class customview extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model("Comment_model");
}
public function yourViewFunction()
{
// get your $id and $student_session_id
$data['teacher_comment'] = $this->Comment_model->GetTeacherComment($id, $student_session_id);
$data['principal_comment'] = $this->Comment_model->GetPrincipalComment($id, $student_session_id);
$this->load->view('your_html_view',$data); //this is the view file name without php
}
}
And now in your html view you can call like this:
print_r($teacher_comment); //you can view the array or object get from model
print_r($principal_comment); //you can view the array or object get from model
I don't know if the title above is an correct title about my question.
Is there a way to declare a variable which we can access it from anywhere in view without need to redefine it again in each function in controller?
for example in controller file Students.php contains many function that handle the views, take a look below :
public function __construct() {
parent::__construct();
$data['count_student'] = $this->m_data->allStudent(); // count all students
}
public function index() {
$data['content'] = 'view-students';
$this->load->view('frontend/header' , $data);
}
public function showDetails() {
$data['content'] = 'view-detail-students';
$this->load->view('frontend/header' , $data);
}
I expected we can access $count_student in both view-students.php and view-detail-student.php without to define $data['count_student'] = $this->m_data->allStudent(); on each function that handle the view.
Is there possible ways to do that?
In the application/core/ create MY_Controller.php
<?php
class MY_Controller extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->model('m_data');
$this->data['count_student'] = $this->m_data->allStudent();
}
}
Controller use $this->data
class Students extends MY_Controller {
public function __construct() {
parent::__construct();
}
public function index() {
$this->data['content'] = 'view-students';
$this->load->view('frontend/header', $this->data);
}
public function showDetails() {
$this->data['content'] = 'view-detail-students';
$this->load->view('frontend/header', $this->data);
}
}
Now that you have extended the controller you shoudld be able to just go like
<?php echo $count_student;?>
On the view
I noticed that you can access variables in views without passing them if you declare them in the controller with $this->. Probably because they default to public visibility.
public function __construct() {
parent::__construct();
// $data['count_student'] = $this->m_data->allStudent(); // count all students
//
$this->count_all_the_students = $this->m_data->allStudents();
}
public function index() {
$data['content'] = 'view-students';
$this->load->view('frontend/header' , $data);
}
And then in the view you can use $this->count_all_the_students without putting it in the $data array.
<?php defined('BASEPATH') OR exit('No direct script access allowed'); ?>
<?php
echo 'I have misled ' . $this->count_all_the_students . ' students with my MVC breaking suggestions.';
If you are using the same variable in every controller function then you have to declare it as follows
class Example extends CI_Controller{
protected $data = array();
public function __construct() {
parent::__construct();
$this->data['count_student'] = $this->m_data->allStudent();
}
public function index() {
$this->data['content'] = 'view-students'; //variables are same
$this->load->view('frontend/header' , $this->data);
}
public function showDetails() {
$this->data['content'] = 'view-detail-students'; //variables are same
$this->load->view('frontend/header' , $this->data);
}
}
This applies only if you have common variables for all views in this controller.
If you are using different variables then use the following code.
class Example extends CI_Controller{
protected $count_student= "";
public function __construct() {
parent::__construct();
$this->count_student = $this->m_data->allStudent();
}
public function index() {
$data['content'] = 'view-students'; //Variable is different
$data['count_student'] = $this->count_students;
$this->load->view('frontend/header' , $data);
}
public function showDetails() {
$data['details'] = 'view-detail-students'; // Variable is different
$data['count_student'] = $this->count_students;
$this->load->view('frontend/header' , $data);
}
}
1.models/calists.php // My model file
Model file here i get the category list from database to the controller
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Catlists extends CI_Model
{
public function __construct()
{
$this->load->database(); //load database
}
public function getCategories()
{
$query = $this->db->get_where('category',array('status'=>'Enable'));
if ($query->num_rows() > 0)
{
return $query->result();
}
else
{
return array();
}
}
}
?>
2.controllers/catlist.php // controller file
Controller to get the data from model
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Catlist extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('catlists');
}
public function catlist()
{
$data['catlist'] = $this->catlists->getCategories();
$this->load->view('home', $data);
}
}
In header am printng the categories list
print_r($data['catlist']);
I am not sure what error you are getting here, but when you are loading model in controller, first letter should be capital.
$this->load->model('Catlists');
$data['catlist'] = $this->Catlists->getCategories();
In header you have to call
print_r($catlist);
The file name must match the class name.
For example
if your class is this:
class User_model extends CI_Model {
function __construct()
{
parent::__construct();
}
}
Your file will be this:
application/models/User_model.php
Here in you case your model name is
models/Calists.php
So your model file be
Model Calists.php
class Calists extends CI_Model {
function __construct()
{
parent::__construct();
}
public function getCategories()
{
$query = $this->db->get_where('category',array('status'=>'Enable'));
if ($query->num_rows() > 0)
{
return $query->result();
}
else
{
return array();
}
}
}
And you call this model file in you controller like this
Controller
public function __construct()
{
parent::__construct();
$this->load->model('calists');
}

Probably you should include your model inside your controller, try to include after parent::__construct
This should look like so:
class Registration extends CI_Controller {
function __construct() {
parent::__construct();
$this->load->model('register_model');
}
or if you using this model in most controllers you can include it using autoload, go to /config/autoload.php search for $autoload['model'] and add your model inside the suitable array
First of all load your model in your controller ..
function __construct() {
parent::__construct();
$this->load->model('register_model');
}
This will work for you...
I'm trying to run two queries in two functions in a model on Codeigniter. The 2nd query runs based on the result of the first by passing the variable between the functions.
The first query gets the row from the 'photos' database based on the URL the user goes to. The second query is run against the 'users' database and the row is selected based on the 'userid' field from the row of the first query.
I need to be able to get all data from the rows of both queries. I get a 404 error at the moment, any ideas as how to get it working?
Code is as follows:
Model:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Viewphoto_model extends CI_Model {
public function get_photo($id)
{
$db_photos = $this->load->database('photos', TRUE);
$db_photos->select('*');
$db_photos->select("DATE_FORMAT(uploaddate, '%d/%m/%y') as uploaddate_formatted", FALSE);
$db_photos->from('photos');
$db_photos->where('approved', '1');
$db_photos->where('id', $id);
$result = $db_photos->get()->row();
$userid = $this->get_user($result->userid);
}
public function get_user($userid)
{
$db_users = $this->load->database('users', TRUE);
$db_users->select('firstname, lastname, email');
$db_users->from('useraccounts');
$db_users->where('id', $userid);
$query = $db_users->get();
return $query->row();
}
}
Controller:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Viewphoto extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('viewphoto_model');
}
public function view($id)
{
$data['photo'] = $this->viewphoto_model->get_photo($id);
if (empty($data['photo']))
{
show_404();
}
$data['user'] = $this->viewphoto_model->get_user($userid);
if (empty($data['user']))
{
show_404();
}
$data['title'] = $data['photo']->title.' by '.$data['photo']->username;
$data['meta_description'] = $data['photo']->description;
$data['directory'] = 'sub';
$this->load->view('templates/header', $data);
$this->load->view('viewphoto/viewphoto', $data);
$this->load->view('templates/footer', $data);
}
}
You seem to have a slight logic issue. Your get_photo() function should return the photo object, which your controller can then use in the call to get_user()...
public function get_photo($id)
{
$db_photos = $this->load->database('photos', TRUE);
$db_photos->select('*');
$db_photos->select("DATE_FORMAT(uploaddate, '%d/%m/%y') as uploaddate_formatted", FALSE);
$db_photos->from('photos');
$db_photos->where('approved', '1');
$db_photos->where('id', $id);
return $db_photos->get()->row();
}
Then in your controller....
public function view($id)
{
$data['photo'] = $this->viewphoto_model->get_photo($id);
if (empty($data['photo']))
{
show_404();
}
// Pass the photo's userid here
$data['user'] = $this->viewphoto_model->get_user($data['photo']->userid);
if (empty($data['user']))
{
show_404();
}
// ...
}
