i want check session and get current user details only one row i new here plz help
public function profile() {
$this->load->view('header');
$this->load->model('brid_groom_fetch');
$this->session->userdata('uname');
//This below line fetch model db data
$row = $this->brid_groom_fetch->get_program_specific_gender();
//here i have check data is in session..
$session_id = $this->session->userdata(
array('uname' => $row->uname));
print_r($sesid);
}
Why don't you use basic == operator ?
public function __construct() {
parent::__construct();
$this->load->model('brid_groom_fetch');
// you need to load session library
// Have you loaded ?
$this->load->library('session');
}
public function profile() {
$this->load->view('header');
// you do not need to load in all method.
// we have already loaded in __construct()
// $this->load->model('brid_groom_fetch');
// use variable
$uname = $this->session->userdata('uname');
//fetch data from db
$row = $this->brid_groom_fetch->get_program_specific_gender();
if ($row->uname == $uname) {
$session_id = $this->session->userdata('session_id');
var_dump($session_id);
}
}
You are setting userdata with
$this->session->set_userdata(array('uname' => $yourname));
or
$this->session->set_userdata('uname',$yourname);
To check what value is set in the userdata you need to use
$sess_name = $this->session->userdata('uname');
print_r($sess_name);
And then validate this $sess_name you have received.
You can also unset the userdata by using
$this->session->unset_userdata('uname');

I am trying to implement a widgets library using load->view. I know I can use include to call directly the file and avoid the vars cache issues but just wondering why it does not work.
Here is how I have structured my code:
My Controller:
class Page extends MY_Controller {
public $data = array();
public function __construct() {
parent::__construct();
...
$this->load->library('widgetmanager');
}
public function index($slug = '') {
echo $this->widgetmanager->show(2);
echo $this->widgetmanager->show(1);
}
}
My Library
class WidgetManager
{
private $CI;
public function __construct()
{
$this->CI = & get_instance();
}
public function show($widget_id) {
$data = array();
$widget_id = (int)$widget_id;
$this->CI->db->select('*');
$this->CI->db->from('widget');
$this->CI->db->where('id', $widget_id);
$query = $this->CI->db->get();
$item = $query->row_array();
$data['widget_title'] = $item['title'];
$data['widget_content'] = $item['content'];
$widget = $this->CI->load->view('widget/'.$item['source'], $data, TRUE);
$data['widget_title'] = '';
$data['widget_content'] = '';
$this->CI->load->view('widget/'.$item['source'], $data);
return $widget;
}
}
widget 1: Calls widget/content
widget 2: Calls widget/banner
What is happening is, the vars set on the first widget call (they are same name as second widget call), get cached, meaning values from the first call are passed to same call. It is weird because are different views.
I have tried:
Using clear_vars(): $this->CI->load->clear_vars(), before and after doing load->view on the library.
Calling load->view with empty array, null, etc
Tried to add a prefix with the widget slug to the vars (that works, but I have to send in some way the prefix to the view, so it is not possible due cache issue)
Any ideas?
Here is what should work.
(I took the liberty of simplifying your database call making it require much less processing.)
public function show($widget_id)
{
$data = array();
$widget_id = (int) $widget_id;
$item = $this->CI->db
->get_where('widget', array('id' => $widget_id))
->row_array();
$data['widget_title'] = $item['title'];
$data['widget_content'] = $item['content'];
$widget = $this->CI->load->view('widget/'.$item['source'], $data, TRUE);
//clear the cached variables so the next call to 'show()' is clean
$this->CI->load->clear_vars();
return $widget;
}
On further consideration The call $this->CI->load->clear_vars(); is probably pointless because each time WidgetManager::show() is called the $data var is recreated with exactly the same keys. When the $data var is passed to load->view the new values of $data['widget_title'] and $data['widget_content'] will replace the values in the cached vars using those keys.
With Codeigniter session.
I have created the ci_session table.
In this table I save session datas in the blob datatype.
$sess_data= array(
'logged_in' => TRUE
);
$this->session->set_userdata($sess_data);
For count all online users, I need to get logged_in==1 value in blob datatype.
For example, user 1 is logged in with Chrome web browser. User2 is logged in with Mozilla. In the database there are 2 sessions with the different session id.
How can i get this all logged_in==1 values in this ci_session table?
This is my model function.
Please help me the fill where place in this function?
public function count_online_users(){
$this->db->select('*');
$this->db->from('ci_session');
$this->db->where(...........);
$query = $this->db->get()->num_rows();
return $query;
}
Check this this method you have to follow
First you have to update logged_in = 1 in your users table as your defined name
after you get number of users are logged_in
// Update user in to call this function
$data = array(
'logged_in' => '1'
);
public function update_user($user_id, $data)
{
$this->db->where('id',$user_id);
$this->db->update('users',$data);
}
// After you get logged in user in total value
public function count_online_users()
{
$this->db->select('*');
$this->db->from('users');
$this->db->where('logged_in','1');
$query = $this->db->get()->num_rows();
return $query;
}
You can use javascript and asynchron request for update field. When you close the window, the handler of window.onunload is called
var unloadHandler = function(e){
//here ajax request to close session
};
window.unload = unloadHandler;
To solve the problem of redirection, php side you can use a counter
class someController extends Controller {
public function methodWithRedirection(){
$this->session->set_userdata('isRedirection', 1);
//here you can redirect
}
}
class homeController extends Controller{
public function closeConnection(){
$this->load->library('session');
if($this->session->userdata('isRedirection')!== 1){
//destroy session
}
}
}
Alright , I have used this way to save the users info and It works perfect,
static public function memberSave($request) {
$signup = false;
$member = new Members();
$member->name = $request['name'];
$member->email = $request['email'];
$member->password = bcrypt($request['password']);
$member->save();
if (!empty($member->id)) {
$new_id = $member->id;
DB::insert("INSERT INTO roles VALUES ($new_id, 5613)");
$signup = true;
Session::flash('sm', 'Thank you! You have signed up successfully!');
}
return $signup;
}
but when making this for editing the profile(by user) It doesn't work
becuase I use new(); (making object)
I also didn't succeed to use find(); so I tried to use this
static public function saveProfile($id,$name,$email,$password) {
$sql = "UPDATE members SET name=?,email=?,password=? WHERE id=?";
$member = DB::select($sql, [$name,$email,$password,$id]);
but when I want to bcrypt the password in laravel doesnt work .
this is the code also in the second page
public function postProfile(ProfileValidation $request) {
if (Members::saveProfile($request['id'], $request['name'], $request['email'], $request['password'])) {
return redirect('');
}
}
I hope getting helped for editing the users profile by laravel , thanks.
Your Members class must extend Eloquent\Model for following this code to work.
class Members extends Model {
// optional
protected $table = 'members';
...
To find and update the member using email,
// find the single member
$member = Members::where('email', request['email'])->first();
// update the member
$member->name = $request['name'];
$member->password = $request['password'];
// now save the updated member
$member->save();
In order to to encrypt Password, Laravel provides Hash Facade,
// import this
use Hash;
...
// encrypt Password
$encrypted = Hash::make($request['password']);
...
if you want your user automatically hash the password at your model put:
public function setPasswordAttribute($value)
{
$this->attributes['password'] = Hash::make($value);
}
and you can directly check for the user if exist create new or update it:
public function saveMember($request)
{
$member = Member::findOrNew($request->email);
//All your input you want to save
$member->save();
}
I try to pass a variable based on a cookie value in my compose function to all my view to build my menu, with the use of serviceproviders recommmended here:
File: Providers/ViewComposerServiceProvicer.php
public function boot(Request $request) { $this->composeTopBar($request);}
public function composeTopBar(Request $request)
{
$cookieValue = $request->cookie('brand');
// if value not set use default value.
if($cookieValue == null)
{
$cookieValue = 1;
}
$brands = \App\Brand::orderBy('priority', 'asc')->get();
foreach($brands as $brand){
if($brand->id == $cookieValue){
$brand->menuActive = true;
}
else{
// show value to debug
$brand->menuActive = $cookieValue;
}
}
view()->composer('front.layouts.top', function ($view) use ($brands) {
$view->with('brandItems',$brands );
});
}
the cookieValue looks like
yJpdiI6IlNJODBvQ1RNM004OWVleyJpdiI6IlNJODBvQ1RNM004OWVleyJpdiI6IlNJODBvQ1RNM004OWVl
While the value in my controller looks like '2' How can i get the original value 2 in my compose function?
I need to get the original value to compare it in my composeTopBar function so I can pass a variable to be true if it equals the cookie value.
Method to set cookie
$response = response()-> view('front.products.category', compact('products','category'));
$response->withCookie(cookie()->forever('brand',1));
return $response;
I ended up using a class based composer .
The reason why this works is because it's called later in the lifecycle of laravel and the Cookie variables are decrypted. When using Closure based composers the values are encrypted.
Try this: put the view() call as a parameter to response().
$response = response(view('front.products.category', compact('products','category')));
$response->withCookie(cookie()->forever('brand', 1));
return $response;
I want to unset and set session in model function depend on passed id.
I have language field for every record and should change session considering that.
in sample word i have a link like this : http://www.mysite.com/report/2020
now this article by this id maybe saved by english language but current session is french.so I should change the session.
here is my code but it dos not work.
//function for checking language by id
public function lang($id)
{
$data = $this->db
->select('language')
->from('content')
->where('id',$id)
->get();
if ($data->num_rows > 0) {
return $data;
}else{
return false;
}
}
//function for reading data from db depend on id and language
public function report($id)
{
$cat=2;
$code=$id;
$langu= $this->lang($id)->row()->language;
if($langu==3){
$this->session->unset_userdata('lang');
$this->session->set_userdata('lang','dr');
}
if($langu==2){
$this->session->unset_userdata('lang');
$this->session->set_userdata('lang','pa');
}
if($langu==1){
$this->session->unset_userdata('lang');
$this->session->set_userdata('lang','en');
}
$language= $this->session->userdata('lang');
$lang=$language;
$data = $this->db
->select('*')
->from('content')
->where('category',$cat)
->where('language',$lang)
->where('id',$code)
->get();
if ($data->num_rows > 0) {
return $data;
}else{
return false;
}
}
the best way to session is:
you have to check the query in model, and call the model in controller, if its true set session data within controller....
Setting Session within the model is not a good idea for an MVC architecture.
Sometimes there is really need to set or get session data in model.
Use then Code Igniter instance like below:
$codeIgniter =& get_instance();
$codeIgniter->set_userdata('data', $data);
// or to read data:
$data = $codeIgniter->userdata('data');
Note that using $this to call set_userdata() or userdata() in model will not work correctly.
