I'm new to laravel 4 and I'm currently having the following problem:
In my routes.php I have the line:
Route::get('maps/{map_type}', 'MapsController#loadMaps');
And in my MapsController I'd like to get the {map_type} to use it.
So my question: How can I retrieve map_type in my Controller?
Your first argument in your loadMaps method is your map type.
public function loadMaps($map_type) {
return $map_type;
}
Take a look at the first two code snippets on http://laravel.com/docs/controllers.
Controllers receive parameters as parameters in the called function:
class MapsController extends BaseController {
public function loadMaps($map_type) {}
}
Check http://laravel.com/docs/controllers#basic-controllers for more info

I am trying to get the second argument from the route in laravel from the following code.
web.php
Route::get('users/{name}/forksnippets/{name2}','Forksnippet#viewforksnippet');
controller
public function viewforksnippet($slug){
dd($slug);
}
getting name here as result
Just add the second argument to the method of the controller.
public function viewforksnippet($slug, $name2)
{
dd($slug, $name2);
}
public function viewforksnippet($name, $name2)
{
dd($name2);
}
Please try this ex
I use Laravel 5.7 for my JSON API web application.
In my routes/api.php file, I created the following route :
Route::apiResource('my_resource', 'API\Resource')->except(['delete']);
I added the corresponding controller and methods (index, show,...) and everythink work perfectly. My issue is the following : I would like to add optional GET params like this :
http://a.x.y.z/my_resource?param=hello¶m2=...
And for instance being able to retrieve 'hello' in my index() method. However, when I print the value of $request->input('param'), it's empty. I just don't get anything.
Yet, if I create a route like this, with an optional parameter:
Route::get('/my_resource/{param?}', 'API\Resource');
I'm able to get the parameter value in my controller method.
Here is my index method :
class Resource extends Controller {
public function index(Request $request)
{
print($request->input('param'));
// ...
}
// ...
}
Am I missing something ? I'm still new in Laravel maybe I missed something in the documentation.
Thanking you in advance,
You can use:
$request->route("param");
I am trying to attach multiple models with one controller using implicit model binding but I am getting the following error if I try to attach more than one model with methods.
index() must be an instance of App\\Http\\Models\\Modelname, string given
Here is my code:
public function index(Model1 $model1,Model2 $model2,Model3 $model3)
{
print_r($application_endpoint);
}
Route:
Route::resource("model1.model2.model3","MyController",["except"=>["create","edit"]]);
Your route should looks like that:
Route::resource("your_route/{model1}/{model2}/{model3}","MyController",[
"except"=>["create","edit"]
]);
Yess you can register routes like these
Route::resource("model1.model2.model3","MyController",["except"=>["create","edit"]]);
but in your controller, you have to
public function index($id,$id2,$id3)
{
print_r($application_endpoint);
}
OR
you can do like this
Route::model('key/key/key', 'MyController')
and in your controller
public function index(Model1 $model1,Model2 $model2,Model3 $model3)
{
print_r($application_endpoint);
}
I have this code in the HomeController#index:
$towns = Town::all();
return Redirect::to('home')
->with('towns', $towns);
Is there any way I can tell Laravel to execute that lines of code before the end of methods and controllers I define without me copying and pasting those lines of code in every method?
You don't need to do that, you can just share this data with all views by using the view()->share() method in a service provider:
view()->share('towns', Town::all());
You can also use a view composer for that:
public function compose(View $view)
{
$view->with('towns', Town::all());
}
You can extend all controllers from your basic controller. Use Controller.php on app/Http/Controllers/controller.php or create new one.
Add myThreeLines to base controller.
controller.php:
function myThreeLines(){
$towns = Town::all();
return Redirect::to('home')
->with('towns', $towns);
}
class TestController extend Controller{
function index(){
return $this->myThreeLines();
}
}
This is a beginner question, but I searched for an hour and couldn't find an answer.
I am trying to write a simple data query which I included in my HomeController
<?php
class HomeController extends BaseController {
public function showWelcome()
{
return View::make('hello');
}
}
$programs=DB::table('node')->where('type', 'Programs')->get();
$programs is undefined so I am guessing that my query didn't work but I have no idea how to debug it. I tried installing firebug and phpbug and chromphp tools but they don't seem to show anything. My apache log doesn't show anything either. Am I missing something? How do I debug this?
You can't use an expression outside of a method when using a class, instead you need to put it inside a method like:
class HomeController extends BaseController {
public function getPrograms()
{
$programs = DB::table('node')->where('type', 'Programs')->get();
// pass the $programs to the programs view for showing it
return View::make('programs')->with('programs', $programs);
}
}
So, for example, if you have a route like this:
Route::get('/programs', 'HomeController#getPrograms');
Then you may use an URL like: example.com/programs to invoke the getPrograms method in the class HomeController.
Probably this answer doesn't help much but I think you should learn the basics (PHP Manual) first so read books and articles online and check the Laravel website to read the documentation.
You can pass the result of that query to the view like so:
class HomeController extends BaseController {
public function showWelcome()
{
$programs = DB::table('node')->where('type', 'Programs')->get();
return View::make('hello', array('programs' => $programs));
}
}
And in your view you will have access to the $programs variable.
I don't know If i'm missing the point, but can't you use the "dd($programs)" to check what is or not is inside the variable?
