Answer 1

Your method signature is incorrect. Request should always be the first parameter:

public function update(Request $request, $id)

Edit:

If you are submitting a form to the server, you should be POSTing to update. If you are navigating to the form, you should be GETing from edit.

Answer 2

You are trying to make a post request on a get route. So change the route from:

Route::get('/projects/edit/{id}','ProjectsController@edit')->name('projects.edit');

to

Route::post('/projects/edit/{id}','ProjectsController@edit')->name('projects.update');

Answer 3

You have defined a get route in your web.php but you are trying to send the form via a POST request.

Change:

Route::get('/projects/edit/{id}','ProjectsController@edit')->name('projects.edit');

To:

Route::post('/projects/edit/{id}','ProjectsController@edit')->name('projects.edit');

And you route name is wrong,

Change your Form action to

<form method="POST" action="{{ route('projects.edit',[$project->id]) }}">
