I am attempting to declare a method/function in my controller that responds to a numerically named route. When I load any page in the site I receive an error stating the controller method could not be found, meaning that Laravel won't even load the application do to some incorrect formatting. I searched for an answer with no luck.
Here is the route I'm attempting to access via my Math controller:
students/academics/math/7-12
Here is the method declaration to look for the route:
public function get712()
Which gives me the following error no matter what page I'm loading:
Call to undefined method Illuminate\Routing\Router::get712()
I'm not sure how to name the function/method in my controller for a purely numeric routes since hyphen is not allowed and there is no upper/lowercase for numbers.
why not pass 7-12 as a variable to a method?
route:
students/academics/math/{number}
controller:
public function getMath($number)
{
// code here
}
I remembered that Laravel used to use underscores in the method name instead of camelCase so after scouring Google with no luck I declared the method like this:
public function get_7_12()
voila!

I'm trying to make a separate function checkUser insede BaseController. But page redirection is not working inside this function. Even inside __construction() function this is not working also. But when I use it in initController or any other controller function, then this is working. How can I solve this problem, please guide me.
BaseController (In my case AdminBaseController)
This is Dashboard Controller
Showing this error
As you can see in the CI4 documentation, initController() is called after __construct(). Then, when you call checkUser(), your response object is still not initialized, thus null.
You could move the code of your __construct() method into the initController() method, in your AdminBaseController.
Am trying to use two different functions from one controller in a single page route
Route::get('/cart','App\Http\Controllers\Frontend\CartController#index');
Route::get('/cart','App\Http\Controllers\Frontend\CartController#alldata');
But the problem is the function alldata works where the function index doesn't
You can't have 2 GET routes with the same path.
Route::get('/cart','App\Http\Controllers\Frontend\CartController#index');
Route::get('/cart/all','App\Http\Controllers\Frontend\CartController#alldata');
The /cart route is overwritten by the alldata(). So the alldata() is calling instead of index().
kindly remove the alldata()'s route and pass the data from index().
Route::get('/cart','App\Http\Controllers\Frontend\CartController#index');
Route::get('/cart','App\Http\Controllers\Frontend\CartController#alldata');
Try to manipulate your logic in controller rather than in route file.
Use conditional in controller function.
I am new in Codeigniter and it's one of the good frameworks of php. But on some conditions I'm confused. Like this one. If any of you have any clarification about my dough, it's a great help for me.
Offcouse redirects refresh the page and $this not but apart from this I want to know - anyhow both of them used to go to somewhere else on view pages or like in other controller or in same controller to other methods.
But we don't use these side by side because when getting any of them it will go to that page or method without checking the next lines.
In case of a normal difference then have lot's of but I just want to know about the condition of going to next page or method when we use redirect or $this like this -
$this->Function($value); //It's method of same controller.
redirect('Controller/function'); //It's also doing same with page reload.
Thank for looking my problem.
Redirect()
When you will call any function of helper in codeigniter then you can call function directly without using any object. Helper in Codeigniter is collection of functions.
Redirect() method is a part of URL helper in Codeigniter.
For your ref. https://www.codeigniter.com/user_guide/helpers/url_helper.html
So, just load helper using $this->load->helper('url'); or you can also mention in autoload.php file.
$this->Function(); used to call a function from same controller
$this->Function(); used to call a function from same controller
redirect()
While building a web application, we often need to redirect the user from one page to another page. CodeIgniter makes this job easy for us. The redirect() function is used for this purpose.
redirect($uri = '', $method = 'auto', $code = NULL)
The first argument can have two types of URI. We can pass full site URL or URI segments to the controller you want to direct.
The second optional parameter can have any of the three values from auto, location or refresh. The default is auto.
The third optional parameter is only available with location redirects and it allows you to send specific HTTP response code.
Redirect means jumping to another function mentioned in the redirect method.
$this->Function($value); => jumping to another function and you can execute the code of the same function as well as pass the value back by returning value.
When you send request to codeigniter generally CI controller gets called and then function which is mentioned in uri segment. like below... So this will be another request.
redirect('Controller/function'); //It's also doing same with page reload.
But when you have to call another function within the same request then you can use below approach
$this->Function($value); //It's method of same controller.
This will execute the given function and return the value within same request.
I am new to laravel,I had wrote api route code to register controller:
Route::post('test','Api\Auth\RegisterController#index');
In Register controller i had written simple code
public function index(Request $request)
{
return 'hello';
}
I am getting the output in postman like:
Sorry, the page you are looking for could not be found.
not hello.

Routes defined in the routes/api.php file are nested within a route
group by the RouteServiceProvider. Within this group, the /api URI
prefix is automatically applied so you do not need to manually apply
it to every route in the file.
You are trying to make a request to a route which does not exist.
In Postman
Change:
http://localhost:8080/App/api/test
To:
http://localhost:8080/api/test
You're telling laravel to route assoaciate '/api/test', not '/App/api/test', which is the adress you're trying to reach.
Also, if you plan to reach that address straight from the location bar of your browser, you should register the 'GET' method as well.
As you are returning something in function you need to use route as get() instead of post().
Route::get('test','Api\Auth\RegisterController#index');
I use $.getJSON() to retrieve some data for a couple of cascading dropdowns in my form. $.getJSON() automatically appends the parameter at the end of the URL like domain.com/controller/method/?parent=5
So, I've declared my method like public function method($parent) which works file, but the same method will be used from other parts of the website that will call it like domain.com/controller/method/5
I tried to create a route in routes.php like the one below:
$route['business/regions/?parent=(:num)'] = 'business/regions/$1';
but it doesn't seem to work. Am I doing something wrong? Maybe ? is confusing the regex parser of the router? Do I have to escape it somehow to make it a 'literal' ? ?
Or is it that router is not used to 'rewrite' get parameters at all? I'm very confused, as it should work but it doesn't and I'm wondering what's wrong with it...
Codeigniter route parameters are for url parameters. It is particularly useful when trying to create a REST styled url pattern.
What you're trying to do is get url query string from the url which is not supported via the Codeigniter router. For you to get what you want you can do the following:
In your routes.php:
$route['business/regions'] = 'business/regions';
and in your controller Business.php:
public function regions() {
//the numeric id you're looking for
$parent = $this->input->get('parent');
}
