Controller
public function category($id = '') {
$offset=..;
$var = $this->pm->get_items_by_category($id,$offset,$start_row);
}
But in my view I have :
<li>Mobile</li>
I think I know what you are trying to say but it's not very clear.
Your link needs to pass the limit and offset as well as the id. So do something like this
<li>Mobile</li>
Then in your controller set up your function like this.
public function category($limit, $offset, $id){
}
If you give more info I can give better answer.

I have six models that I need to get in one instance in my controller. How can I do that?
I have my six models:
CommentaireCritique
CommentaireNews
CommentaireDossier
CommentaireEpisode
CommentaireSerie
CommentaireTrailer
They all have the same structure in my database, and I would like to show the latest comms on one single page. I don't know if it's possible to bind them in a single controller. I tried that, but it's not working.
public function index()
{
$comms = CommentaireCritique::all() && CommentaireNews::all()
&& CommentaireDossier::all() && CommentaireEpisode::all()
&& CommentaireSerie::all() && CommentaireTrailer::all()
->get();
return view('admin.commentaires.index', compact('comms'));
}
just after the namespace , before the class declaration
use yourAppNameSpace/modelName
There is no limits to the number of models you can instantiate in your controller as long as you declare them above correctly.I think what you need is way to merge the result of all the models if that is so, then you have to use the merge method, otherwise can you please clarify a little bit your question.
yes, you can retrieve them at one controller,
you're already halfway there, you should separate on different variable
public function index()
{
$comms = CommentaireCritique::all()
$news = CommentaireNews::all()
$dossier = CommentaireDossier::all()
$episodes = CommentaireEpisode::all()
$series = CommentaireSerie::all()
$trailers = CommentaireTrailer::all()
return view('admin.commentaires.index', compact('comms','news','dossier','episodes','series','trailers'));
}
if you want put them in one variable, you can use collection docs
All of the results from all() function returns laravel collections. So use concat() function to concatenate all those into one collection
public function index()
{
$coms = CommentaireCritique::all()
->concat(CommentaireNews::all())
->concat(CommentaireDossier::all())
->concat(CommentaireEpisode::all())
->concat(CommentaireSerie::all())
->concat(CommentaireTrailer::all());
return view('admin.commentaires.index', compact('comms'));
}
I need to send the same result to almost every view page, so I need to bind the variables and return with every controller.
My sample code
public function index()
{
$drcategory = DoctorCategory::orderBy('speciality', 'asc')->get();
$locations = Location::get();
return view('visitor.index', compact('drcategory','locations'));
}
public function contact()
{
$drcategory = DoctorCategory::orderBy('speciality', 'asc')->get();
$locations = Location::get();
return view('visitor.contact', compact('drcategory','locations'));
}
But as you see, I need to write same code over and over again. How can I write it once and include it any function whenever I need?
I thought about using a constructor, but I cannot figure out how I can implement this.
You are able to achieve this by using the View::share() function within the AppServicerProvider:
App\Providers\AppServiceProvider.php:
public function __construct()
{
use View::Share('variableName', $variableValue );
}
Then, within your controller, you call your view as normal:
public function myTestAction()
{
return view('view.name.here');
}
Now you can call your variable within the view:
<p>{{ variableName }}</p>
You can read more in the docs.
There are a few ways to implement this.
You can go with a service, a provider or, like you said, within the constructor.
I am guessing you will share this between more parts of your code, not just this controller and for such, I would do a service with static calls if the code is that short and focused.
If you are absolutely sure it is only a special case for this controller then you can do:
class YourController
{
protected $drcategory;
public function __construct()
{
$this->drcategory = DoctorCategory::orderBy('speciality', 'asc')->get();
}
// Your other functions here
}
In the end, I would still put your query under a Service or Provider and pass that to the controller instead of having it directly there. Maybe something extra to explore? :)
For this, you can use View Composer Binding feature of laravel
add this is in boot function of AppServiceProvider
View::composer('*', function ($view) {
$view->with('drcategory', DoctorCategory::orderBy('speciality', 'asc')->get());
$view->with('locations', Location::get());
}); //please import class...
when you visit on every page you can access drcategory and location object every time
and no need to send drcategory and location form every controller to view.
Edit your controller method
public function index()
{
return view('visitor.index');
}
#Sunil mentioned way View Composer Binding is the best way to achieve this.
The problem looks basic but it is really painful!
I'm using get method and getting value in controller and I want the same value to return in another view.
How can I do that???
Please help!!!
This is my function from controller:
public function guest(){
if (Input::get('Cash On Delivery')){
$get = Input::get('Cash On Delivery');
return Redirect::to('guest/guestview/'.$get);
}
Well, with regards to your answer, using $_REQUEST directly is not Laravel's way of doing things :(
I believe this is better
public function guest(Request $request)
{
if ($request->payment_method == ('Cash On Delivery'))
{
return view('guest/guestview', ['guest'=>$request->payment_method]);
}
}
Ok Guys, I figured it out,
Just do this below.
public function guest(Request $request){
if ($request->payment_method == ('Cash On Delivery')){
$get = $_REQUEST['payment_method'];
return view('guest/guestview', compact('get'));
}
My current setup:
Controller:
public function showGeneralPage($id, ShowClinicFormRequest $request)
{
return View::make('clinic.general', ['clinic' => Clinic::where('id', $id)
->first()]);
}
ShowClinicFormRequest:
public function authorize()
{
$clinicId = $this->route('clinic');
return Clinic::where('id', $clinicId)
->where('user_id', Auth::id())
->exists();
}
Route:
Route::get('clinic/{id}/general', 'ClinicController#showGeneralPage
When trying to click through to the page - General, it presents a forbidden error.
To be honest, I'm not overly fussed on even having to show the ID based on the clinic, within the URL, but I can't see any other way around it? Any help would be hugely appreciated. Many thanks.
You may try this (I've found three problems tho):
$id = $this->route()->parameter('id'); // $this->route('id') works as well
Also you need to pass the id when generating the URI, for example:
{{ url("clinic/{$id}/general") }} // $id may have some value, i.e: 10
Also, you need to change the order of parameters here:
public function showGeneralPage($id, ShowClinicFormRequest $request)
Should be:
public function showGeneralPage(ShowClinicFormRequest $request, $id)
Note: When using Method Injection place your method parameters after the type hinted dependency injection parameters.
There are two problems here. First, you have to pass the id along when generating the URL. Assuming a variable $id:
url('clinic/'.$id.'/general')
Second, you are trying to retrieve the parameter clinic, however it is actually called id.
Change it to:
$clinicId = $this->route('id');
I have a function that needs to pull arguments from the URL like CI is supposed to do. But it's not doing it. My URL is domain.com/lasers/en/acme.
My class Lasers is:
class Lasers extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('products_model');
$this->load->model('common_model');
$this->load->model('select_country_model');
$this->load->model('markets_materials_model');
}
function index($lang = NULL, $laser = NULL)
{
$query = $this->products_model->get_product_content($laser, $lang);
}
The model is loaded in the constructor. The $lang I need is "en" and the $laser I need is "acme". So why isn't this working? The arguments in the function are in the correct order, so I can't see what's wrong.
By default you cant pass arguments to the index method of a controller
if you go to domain.com/lasers/en/acme it is looking in the lasers controller for a method called en.. (which doesn't exist) and trying to pass a single parameter of acme to it
Theres a few solutions, probly the easiest is to use a different method (not index) then use routes to make the URLs work.
add something like this to your config/routes.php
$route['^lasers/(:any)/(:any)'] = "lasers/get_products/$1/$2";
Then use a method like this instead of index:
function get_products($lang = NULL, $laser = NULL) {
$query = $this->products_model->get_product_content($laser, $lang);
}
.. OR you could use _remap to override the default behaviour
Does it work if you write "domain.com/lasers/index/en/acme"?
If you write domain.com/lasers/en/acme, it will look for the "En" function, $lang being "acme", and $laser remaining NULL.
