How to detect where request is coming from?

Question

Currently I have a Controller which controls the data sent and operation done.
For example, when I hit the home page, I would hit Route::get('home', 'Controller@select'); which will select existing data and show it at that page.
On the same page, I have provided a form which user can input data into it and press the submit button which will hit this one Route::post('home', 'Controller@insert'); , this works since it can differentiate between GET (from other page to home) and POST (from same page, but entered from the submit button form).

Now, I have the DELETE button on the very same page, but this one is that I'm using get, so if I still use Route::get('home', 'Controller@delete'); , it won't work, since it the Controller@select will override it.

My question is that how do I detect where the request is coming from so I can prepare different operation for different request from the user?
I have a basic PHP knowledge, and I kinda want it similar to like if(isset($_GET['delete'])) , do delete operation.

Another solution would be to move all the page to a different page, then redirect it to the home page but I still want to stick with the same page so it is convenient for the user to see the data flow easily.

Answer 1

You need to change the route for example if you use Route::get('home', 'Controller@select'); it's mind you are pointing to Controller->select() method when you go to the url home for delete you should try something like Route::get('home/delete', 'Controller@delete'); that mind when you go to the url home/delete will point to Controller->delete()

You can either add "?delete=1" and then check it in "select" method;

Route::post('delete', 'Controller@drop');

or you can make Route::delete('home', 'Controller@drop') ; But then you have to make delete request through ajax request like:

 $("#deleteButton").click(function() {
     $.ajax({
      method: "DELETE",
      url: "index.php",
     })
    });

When ever you are trying to perform delete operation you should set method as DELETE . However, by default we have only GET and POST methods. Laravel has nice wrap around( method_field() ) for this to work. You simply have to add _method field to the form.

Register Route

Route::destroy('home', 'Controller@destroy');

By HTML form

<form method="POST" action="home">
    {!! csrf_field() !!}
    {!! method_field('DELETE') !!}
</form>

By Ajax

$.ajax({
    url: "home",
    method: "POST",
    data : { '_method' : 'DELETE', '_token' : 'YOUR CSRF TOKEN HERE'}
})

I use a dummy page from the form action like action="insert", then at the Route: Route::post('insert', 'Controller@insert'); and at the Controller is just doing the operation and return back the view to ('home').
