Laravel 6 route variable Controller method

Question

I want to make one route for all my ajax requests in laravel. Currently what I have is:

Route::post('/ajax/{method}', 'AjaxController@index')->name('ajax-request');

Can I do something like this (using dynamic method name):

Route::post('/ajax/{method}', 'AjaxController@{method}')->name('ajax-request');

so for example when I call /ajax/get_comments , it will call AjaxController@get_comments method ?

Answer 1

You can add closure function to your route to achieve this one.

Route::get('ajax/{method}', function($method){

    $app = app();

    $controller = $app->make('App\Http\Controllers\AjaxController');

    return $controller->callAction($method, $parameters = array());

});

Now, call the get_comments method like:

localhost:8000/ajax/get_comments

NOTE: make sure your controller is inside app/Http/Controller/ directory.

I hope you understand

Answer 2

The Route methods( get , post etc) can accept their's second parameter as string using the following pattern ControllerName@methodName .

You could retrieve the {method} parameter from request path and append it to Route method's second parameter. ie, like 'ControllerName@'. 'methodName' 'ControllerName@'. 'methodName'

Try the following :

Assuming {method} would be your second segment in the request path. [If not change the value in the segment() parameter.]

Try the following:

Route::post('/ajax/{method}', 'AjaxController@'.(Request::segment('2')))->name('ajax-request');

Please Note :

If you choose to put URL parameter to be used as the method name there are some chance that, if a user is able to change the request path other than the specified one, run time exceptions will be thrown.

Consider the following scenario :

Your AjaxController has only methods get_comments() and get_deleted_comments() .

If the request is /ajax/get_comments or /ajax/get_deleted_comments then their corresponding methods will work. But if request is something like /ajax/get_xyz and you dont have a method named get_xyz in your AjaxController then a BadMethodCallException will be thrown.
