$result = $this->city_model->get_cities($country);
$this->output->set_output(json_encode($result));
}
}
public function get_cities($country) {
$this->load->model('city_model');
$this->output->set_content_type('application/json');
$this->output->set_status_header(200);
$this->output->set_output(
json_encode(
$this->city_model->get_cities($country)
)

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'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)
{
$this->db->where('id', $visitor_id);
$this->db->update('invitation_codes', $attendance_status);
}
The Code Runs Fine when i run the code without login Conditions, When i put code under login condition it gets stop. if a login into application even that time code is not under login conditions but the search gets stop until i restart my computer

I am new in ci. Using this code I want to create a autocomplete suggestion box in codeigniter But this code is not work for me. So, how can I create autocomplete suggestion box in ci and please tell me what wrong in my code can I use this code for autocompletion.
Thank You
UPDATED You can try this:
in you Model Fetch_data.php
<?php
class Fetch_data extends CI_Model
{
function __construct()
{
parent::__construct();
}
public function autocomplete()
{
$this->db->select('college_name,field');
$this->db->from('all_colleges');
$this->db->order_by('college_name');
$query = $this->db->get();
$result = $query->result_array();
return $result;
}
}
controller: Test.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Test extends CI_Controller
{
function __construct()
{
parent :: __construct();
$this->load->helper(array('form', 'url'));
$this->load->model('Fetch_data');
}
public function index()
{
$all_data = array();
$result = $this->Fetch_data->autocomplete(); //collect all college name
foreach($result as $key=>$value){
array_push($all_data, $value["college_name"]);
}
$data['search'] = $all_data;
$this->load->view('index',$data);
}
}
view: index.php
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
<input type="text" name="colleges" id="colleges" class="form-control" />
<input type='hidden' id='mydata' value='<?php echo json_encode($search);?>' />
<script>
$( function() {
var oData = $("#mydata").val();
oData = JSON.parse(oData);
$( "#colleges" ).autocomplete({
source: oData;
});
});
</script>
You can get all the college_names and store it with a variable then when you enter a letter you can no longer use ajax because it is already stored with a variable.
Hope it will work.
I'm a newbe in codeigniter.
something is going wrong with I think the model.
this is the controler:
<?php
class Fuel extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->helper('html');
$this->load->library('table');
}
public function image() {
$data['title'] = 'test';
$data['main_content'] = 'imagetest';
$this->load->view("template", $data);
}
public function overview() {
$this->load->model('Get_DB');
$this->Get_DB->overview() ;
$data['title'] = 'overview';
$data['main_content'] = 'overview';
$this->load->view("template", $data);
}
when I load the image function, it works just fine, but the function overview is the problem.
this is my model:
<?php
class Get_DB extends CI_Model
{
function __construct()
{
// Call the Model constructor
parent::__construct();
}
public function overzicht() {
$query = $this->db->query("SELECT * FROM invoer "
. "ORDER BY datum DESC");
$gen_query = $this->table->generate($query);
return $gen_query;
}
}
and this is my view:
<?php
echo $gen_query;
and if you want to know: my template is this:
<?php
$this->load->view('templates/header');
$this->load->view($main_content);
$this->load->view('templates/footer');
now when I open my view I get this message:
A PHP Error was encountered
Severity: Notice Message: Undefined variable: gen_query Filename:
views/overzicht.php Line Number: 3
in the model you see that I have made a var $gen_query
so why is that undifined?
regards,
Ralph
Try:
public function overview() {
$this->load->model('Get_DB');
$data = array();
$data['gen_query'] = $this->Get_DB->overzicht() ; #corrected model function and save the result in `gen_query`
$data['title'] = 'overview';
$data['main_content'] = 'overview';
$this->load->view("template", $data);
}
In Controler:
public function overview() {
$this->load->model('Get_DB');
$result = $this->Get_DB->overview() ;
$data['title'] = 'overview';
$data['main_content'] = 'overview';
$data['re'] = $result;
$this->load->view("template", $data);
}
And In view page you can retrive the result
like
foreach($re->result() as $row)
{
//You can get each row data here $row->your_field_names
}
