I have trouble to access more than one config rest server in CI.. I have 2 rest will I want to access,
http://localhost/sia/Rest_server and http://localhost/sia/Rest_physics.
but I do not know how to access the rest of the servers in a single controller.
This is the code:
public function __construct(){
parent::__construct();
$this->load->library('rest');
$config = array('server' => 'http://localhost/sia/Rest_server/');
$this->rest->initialize($config);
}
public function inputMhs($jurusan = NULL){
if (!in_array ($jurusan, array ('ilkom', 'fisika'))){
show_404();
return;
}
$this->load->view('admin/header');
$data['jurusan'] = $jurusan;
$data['data'] = $this->rest->get('ambilmhs', 'json');
$this->load->view('admin/v_inputmhs',$data);
$this->load->view('admin/footer');
}

routes.php
$route['default_controller'] = 'home';
$route['404_override'] = 'my404';
$route['translate_uri_dashes'] = FALSE;
$route['app'] = "/app/home";
$route['site'] = "/home";
when accessed through the link http://localhost/escola/app/simulado, the system behaves in the desired way, it writes the value zero once in the database, for example.
accessing the url we have the method of the class, simulated, http://localhost/escola/app/simulado/materia/1/exatas-matematica calls the method in the correct way, but when writing to the database it writes the code of the matter.
I did a test and put the same code of the article method in the index and called the url, and it worked perfectly, writing only once the code of the article in the database.
I need to know why it is recording 3 times in the database when accessing the url is a method of the class and has parameters.
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.
I'm trying to build a multi tenant app, where I have configured the database, the views folder, I know there must be some way out to configure the credentials of social app login for socialite. Well I tried few things to set it dynamically.
STEP 1
I created a class with the name of socialite in a separate folder and when the social login is called I'm implementing the following in my controller:
public function redirectSocialLogin()
{
$social = new SocialiteProvider();
$fb = $social->makeFacebookDriver();
return $fb->redirect();
}
and while callback I used following:
public function callbackSocialLogin($media)
{
$user = Socialite::driver($media)->user();
$data['name'] = $user->getName();
$data['email'] = $user->getEmail();
dd($data);
}
In my class I've following codes:
public function makeFacebookDriver()
{
$config['client_id'] = 'XXXXXXXXXXXXXXX';
$config['client_secret'] = 'XXXXXXXXXXXXXXX';
$config['redirect'] = 'http://XXXXXXXXXXXX/auth/facebook/callback';
return Socialite::buildProvider('\Laravel\Socialite\Two\FacebookProvider', $config);
}
It redirects perfectly to the social page but while getting a callback I'm getting an error, It again fetches the services.php file for configuration and doesn't get any.
STEP 2
I made a ServiceProvider under the name of SocialiteServiceProvider and extended the core SocialiteServiceProvider and placed the following codes:
protected function createFacebookDriver()
{
$config['client_id'] = 'XXXXXXXXXXXXXXX';
$config['client_secret'] = 'XXXXXXXXXXXXXXXXXXXX';
$config['redirect'] = 'http://XXXXXXXXXXX/auth/facebook/callback';
return $this->buildProvider(
'Laravel\Socialite\Two\FacebookProvider', $config
);
}
But again it throws back error which says driver is not setup. Help me out in this.
Thanks.
In your STEP 1, update the callback as below mentioned & try. $media is actually Request. So when initialising Socialite::driver($media) you are actually passing Request where you have to pass Facebook.
public function callbackSocialLogin(Request $request) {
$fbDriver = (new SocialiteProvider())->makeFacebookDriver();
$user = $fbDriver->user();
$data['name'] = $user->getName();
$data['email'] = $user->getEmail();
...
}
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'm using codeigniter, for make an api rest, with the library that provide the oficial web site.
The problem is: the file routes.php doesn't redirect well. When i put localhost/API/1 into my browser apear the 404 error.
Here my controller "Apicontroller":
public function __construct() { //constructor //no tocar
parent::__construct();
$this -> load -> model("Modelocontrolador");
}
public function index_get() { //get all the info
$datos_devueltos = $this->Modelocontrolador->getPrueba(NULL, "Usuarios");
if(!is_null($datos_devueltos)){
$this->response(array("response" => $datos_devueltos), 200);
}else{
$this->response(array("response" => "No date"), 200);
}
}
public function find_get($id){ //select where
$datos_devueltos = $this->Modelocontrolador->getPrueba($id, "Usuarios");
if($id != NULL){
if(!is_null($datos_devueltos)){
$this->response(array("response" => $datos_devueltos), 200);
}else{
$this->response(array("response" => "No date"), 200);
}
}else{
$this->response(array("response" => "No dates for search"), 200);
}
}
public function index_post() { //insert in la table
if(! $this -> post("dato")){
$this->response(array("response" => "No enought info"), 200);
}else{
$datoID = $this -> Modelocontrolador -> save($this -> post("dato"),"UsuariosJJ");
if(!is_null($datoID)){
$this->response(array("response" => $datoID), 200);
}else{
$this->response(array("response" => "No found it"), 200);
}
}
}
public function index_put($id) { //"update"
if(! $this -> post("dato") || ! $id){
$this->response(array("response" => "No ha mandado informacion correcta para el update"), 200);
}else{
$datoID = $this -> Modelocontrolador -> update("Uid",$id,$this -> post("dato"),"UsuariosJJ");
if(!is_null($datoID)){
$this->response(array("response" => "Dato actualizado"), 200);
}else{
$this->response(array("response" => "Error modify"), 200);
}
}
}
public function index_delete($id) {
if(! $id){
$this->response(array("response" => "Not enought info"), 200);
}else{
$delete = $this-> Modelocontrolador -> delete("Uid",$id,"UsuariosJJ");
}
if(!is_null($delete)){
$this->response(array("response" => "Date delete"), 200);
}else{
$this->response(array("response" => "Error delete"), 200);
}
}}
And my routes file:
$route['default_controller'] = 'Apicontroller';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
/*sub-rutas*/
/*---------*/
$route["Apicontroller"]["get"] = "Apicontroller/index"; //basico
$route["Apicontroller/(:num)"]["get"] = "Apicontroller/find"; //select
$route["Apicontroller"]["post"] = "Apicontroller/index"; //insert
$route["Apicontroller/(:num)"]["put"] = "Apicontroller/index/$1"; //update
$route["Apicontroller/(:num)"]["delete"] = "Apicontroller/index/$1"; //delete
If the browser request literally uses /API then routing needs to 'see' exactly that. Also, the route rules must be explicit with the method to be called. (Hopefully the code shown reflects the mapping you had in mind.)
/*sub-rutas*/
/*---------*/
$route["API"]["get"] = "Apicontroller/index_get"; //basico
$route["API/(:num)"]["get"] = "Apicontroller/find_get/$1"; //select
$route["API"]["post"] = "Apicontroller/index_post"; //insert
$route["API/(:num)"]["put"] = "Apicontroller/index_put/$1"; //update
$route["API/(:num)"]["delete"] = "Apicontroller/index_delete/$1"; //delete
Using the above routes I created some test code. Here are those files.
The much simplified Apicontroller.
class Apicontroller extends CI_Controller
{
function __construct()
{
parent::__construct();
}
function index_get()
{
echo "API index";
}
public function find_get($id)
{ //select where
echo "API find_get $id";
}
public function index_post()
{
echo 'API index_post';
}
public function index_put($id)
{ //"update"
echo "API put $id";
}
}
I don't believe that because your Apicontroller is extending a different Class the results would change. That may be a drastic assumption.
In order to test POST calls I used these two files.
First a Testpost.php controller
class Testpost extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->helper('form');
}
public function index()
{
$this->load->view("test");
}
}
The very simple view (test.php) loaded by the above.
<?php
echo form_open("API");
echo form_submit('mysubmit', 'Submit Post!');
echo form_close();
Directing the browser to localhost/testpost shows a page with a single submit button. Pressing the button results in a screen with the text "API index_post".
Sending the browser to localhost/API/3 produces a screen with the text "API find_get 3".
localhost/API produces "API index".
Now the interesting thing (not related to your problem, but interesting).
Given the default
$route['default_controller'] = 'Apicontroller';
and the route
$route["API"]["get"] = "Apicontroller/index_get";
I expected that directing the browser to the home page localhost would produce "API index". But it doesn't. It results in a 404. Due to that behavior it might be wise to be more explicit with default_controller
$route['default_controller'] = 'Apicontroller/index_get';
Or add an index() function to Apicontroller that calls $this->index_get().
I did not test PUT or DELETE as my server isn't setup to handle them. But as GET and POST seem to function, in a righteous world, they will work.
seems like you are using PHil's REST_Controller library with CI 2.x, correct ?
If so, I would recommend you to use what I like to call an "index gateway" because you can't do per-Method routing with CI2:
class Apicontroller extends REST_Controller
{
function index_gateway_get($id){
$this->get_get($id);
}
function index_gateway_put($id){
$this->put_put($id);
}
// This is not a "gateway" method because POST doesn't require an ID
function index_post(){
$this->post_post();
}
function get_get($id = null){
if(!isset($id)){
// Get all rows
}else{
// Get specific row
}
}
function put_put($id = null){
if(!isset($id)){
// a PUT withtout an ID is a POST
$this->post_post();
}else{
// PUT method
}
}
function post_post(){
// POST method
}
}
The routing to make this work is really easy:
$route["API/(:num)"] = "Apicontroller/index_gateway/$1";
That's all you need. Phil's REST Library will redirect to the correct index_gateway_HTTPMETHOD depending on which method is used.
Each index_gateway_HTTPMETHOD will then redirect to the correct method.
As far as I know, this trick is the only way to have CI2 use a single /API/ entry point that works for all HTTP Methods.
