Use database from annotation.php file to create dynamic routes in symfony - php

I am trying to create a dynamic router for my symfony application where on a base of some condition I want to set the prefix of a route, the condition based prefix is working as I use the statically coded condition, see my router with dummy route, main symfony route for Bundle
(config/routes/annotation.php)
<?php use Symfony\Component\Routing\Loader\Configurator\RoutingConfigurator;
return function (RoutingConfigurator $routes) {
$resultRout = $routes->import('#MyCustomBundle/Controller/Test/', 'annotation')
->defaults(['_locale' => '%locale%'])
->requirements(['_locale' => '%app_locales%']);
// get $validate value from database
if ($validate) {
$resultRout->prefix('/{_locale}/app/{default_path}/');
} else {
$resultRout->prefix('/{_locale}/site/{new_path}/');
}
};
The issues I face are:
1: I need to clear route caching every time for different route condition. Is there a way to stop route caching?
2: I want to access database so that I can create $validate as per the DB values. How to load entity manager?
Also if there is a better way to achieve this type of routing please suggest.

How to prevent users from checking not existing urls, how to hide routes in Laravel 8.*

First question was solved with findOrFail method
Is there any way to prevent users from checking non-existing routes?
Example
I've got route to http://127.0.0.1:8000/event/9
but event with id 8 does not exist, if user would go to that id there is a massage:
Attempt to read property "photo_patch" on null (View: C:\xampp\htdocs\Laravel1\resources\views\frontend\eventView.blade.php)
Or any other error from db that record does not exist.
Second question
How to turn on preety URLs in laravel
So my page with display http://127.0.0.1:8000 not http://127.0.0.1:8000/events something...
I know that its somewere in config files but I cant find it.
Example class and route that uses it:
-----------------------------Class----------------
public function eventView($id)
{
$notDisplay = Auth::user();
$eventView = Event::findOrFail($id);
if(!$notDisplay){
$eventView->displayed = $eventView->displayed +1;
$eventView->save();
}
return view('frontend/eventView', ['eventView' => $eventView]);
}
----------------Route-----------------
Route::get('event/' . '{id}', [App\Http\Controllers\FrontendController::class, 'eventView'])->name('eventView');
First off, use the container!
Laravel's service container is very powerful and your controller resolve use-case is one of the most common places you should be using it. The url argument and controller argument MUST match for this to work.
Your route:
Route::get('event/' . '{event}', [App\Http\Controllers\FrontendController::class, 'eventView'])->name('eventView');
Your Controller:
public function eventView(Event $event)
{
return view('frontend/eventView', ['event' => $event]);
}
When leveraging Laravel's dependency injection and container, you get your findOrFail() for free. You should also remove your auth check, and handle that with route middleware.
In terms of "prettifying" urls, Laravel's route model binding feature allows you to control what property of a model is used to for container resolution. For example, let's imagine your event has a unique slug you'd like to use instead of the auto-increment id:
Route::get('event/' . '{event:slug}', [App\Http\Controllers\FrontendController::class, 'eventView'])->name('eventView');
Laravel's routing functionality offers a fallback feature that would allow you to fine-tune where the user is redirected if the route model binding failed.
https://laravel.com/docs/8.x/routing#fallback-routes
With regard to preventing an unauthorized individual from editing someone else's event. The first place I would put protections in place would be at the time of persistence (when saving to the database). While you can do this in every place in your codebase where persistence occurs, Laravel's Observer feature could be a great fit. That way, you can be confident that no matter what code is added to your app, the ownership check will always be run before making any changes to events.
https://laravel.com/docs/8.x/eloquent#observers
The second place that I would put protections in place would be with a route middleware on any routes that can mutate the event. That way, you can redirect the user away from an event they don't own before they even have a chance to attempt to edit it.

How to use multiple controllers and model in codeigniter 3.1.4?

I am very new to codeigniter and i am using the version 3.1.4.
I have 2 users in my system and i wanted to use 2 different controllers in the same system, since i felt that using one single controller will have too many functions in it.
what i found as solution was similar to these: How do you use multiple controllers in CodeIgniter?
i dont find any $route['(:any)'] in my routes file.
Please help me solve this with every step since i am very new.
I want to know how to route it and how to call the function (in both the controllers) in a view page as well as model.
Also i need help in using 2 models.(for that i think i just need to mention the model name while calling the fucntion in model)need advice.
You can use routing for all user to redirect to same controller with the routing rule:
$route['users/(:any)'] = "users/index/$1";
for example-
I have two user manager and admin
http://localhost/project/users/manager/create
http://localhost/project/users/admin/create
both request redirect to users/index and now you can get value of the function using
$func = $this->uri->segment(3, 'list');
$user_type = $this->uri->segment(2, 0);
Now use switch case for call a function
switch ($func) {
case 'create':
$this->create($user_type);
return;
default:
$this->view($user_type);
return;
}

Mapping route to another route in Laravel

I am developing an application in the Laravel 5.2 which must have a friendly URL-s. This is not problem with the regular way, where the {slug} wildcard is handled by a controller but I want to make it in a different way.
For now I have only two controllers:
ProductsController#show to show details product
CategoriesController#show to show selected category with listing products which are assigned to it
And routes:
Route::get('product/{product}', 'ProductsCategory#show')->name('product.show');
Route::get('category/{category}', 'CategoriesController#show')->name('category.show');
So when I want to echo a just use route('product.show', compact('product'))
Nothing special until I want to handle different URL-s which are fetched from a database. I thought it will be possible to make an another routes which are assigned to existing and when I use a route(...) helper it will be handled automatically. But it is not. So for example I have a new URL:
domain.com/new-url-for-product.html
so by route it should be assigned to the regular 'product.show' route with some ID, which is handled by route model binder for {product} wildcard. The same for route(..) helper it should print friendly URL-s.
I don't know if my strategy is good. How do you handle with the similar problems?
of course route will handle this automatically. have a look into this. I am just giving you example, you have to set this code as per your need.
route('product.show', 'product'=>'new-url-for-product.html');
will generate this
domain.com/new-url-for-product.html
route('product.show', 'product'=>'new-url2-for-product.html');
will generate this URL
domain.com/new-url2-for-product.html
and so on, and then you have to handle all this in your controller method.
eg: your controller method for this route is ProductsCategory#show which is
public function show($product){
if($product == 'new-url-for-product.html'){
//perform this
}
if($product == 'new-url2-for-product.html'){
//perform this
}
}
this just an example, you have to map this according to your need
Edited Here is the example I tested it
Route::get('/product/{product}.html', ['as'=>'product.show', 'uses'=>'ProductsCategory#show']);

cakephp 3 prefix routing

I'm trying to set up a routing prefix in cakephp 3 so any URLs starting with /json/ get the prefix key set and I can change the layout accordingly in the app controller. Other than that, they should use the usual controller and action. I have added the following to routes.php
$routes->prefix('json', function($routes) {
$routes->connect(
'/:controller/:action/*',
[],
['routeClass' => 'InflectedRoute']
);
});
I want to direct all requests with json as first url segment to controller specified in second url segment. e.g. /json/users/add_account_type/ goes to users controller. However when accessing this URL I get the message:
Error: Create the class UsersController below in file:
src/Controller/Json/UsersController.php
whereas I want it to be using
src/Controller/UsersController.php
I think this should be possible but I can't quite see what I'm doing wrong when consulting the book. Have partly based my code on: CakePHP3.x controller name in url when using prefix routing
Thanks a lot in advance
That's simply how prefix routing now works in 3.x, as explained in the docs, prefixes are being mapped to subnamespaces, and thus to separate controllers in subfolders.
http://book.cakephp.org/3.0/en/development/routing.html#prefix-routing
If you'd wanted to change that behavior (I don't really see why), one way would be to implement a custom ControllerFactory dispatcher filter.
http://book.cakephp.org/3.0/en/development/dispatch-filters.html
On a side note, the RequestHandler component supports layout/template switching out of the box, so maybe you should give that a try.
http://book.cakephp.org/3.0/en/controllers/components/request-handling.html
http://book.cakephp.org/3.0/en/views/json-and-xml-views.html
Prefix routing is a way of namespacing parts of your routes to a dedicated controller. It seem that what you want is a scope and not a prefix, for what you describe:
Router::scope('/json', function($routes) {
$routes->fallbacks('InfledtedRoute')
});

PHP Laravel extending resource routing

Laravel routing functionality allows you to name a resource and name a controller to go with it. I am new to Laravel and would like to know if anyone knows how to extend the resources method in the route class provided.
Basically say I have: (which works fine)
/invoices
But say I want:
/invoices/status/unpaid
How is this achievable?
To see the basics of what I am doing check:
http://laravel.com/docs/controllers#resource-controllers
Resource controllers tie you into a specific URLs, such as:
GET|POST /invoices
GET|PUT /invoices/{$id}
GET /invoices/create
and so on as documented.
Since, by convention, GET /invoices is used to list all invoices, you may want to add some filtering on that:
/invoices?status=unpaid - which you can then use in code
<?php
class InvoiceController extends BaseController {
public function index()
{
$status = Input::get('status');
// Continue with logic, pagination, etc
}
}
If you don't want to use filtering via a query string, in your case, you may be able to do something like:
// routes.php
Route::group(array('prefix' => 'invoice'), function()
{
Route::get('status/unpaid', 'InvoiceController#filter');
});
Route::resource('invoice', 'InvoiceController');
That might work as the order routes are created matter. The first route that matches will be the one used to fulfill the request.
