 **processing delete requests** are like posts, but we can't set the form method to ''DELETE'' so we need to use a blade function ''@method('DELETE')'' just after the form tag.
+**sessions and flashing data** in laravel we can either store data into our session, like in normal php.. we can do this either via the ''session()'' helper which will save new key=>value pairs when it is passed an array as argument like ''session(['newkey',$someVar])'' for example. to get ''$someVar'' back we would use the helper like ''$someVar=session('newkey')''. alternatively, we can use an instance of the ''Request'' class and the ''put()'' and ''get()'' functions for the ''session'' property like so: ''$request->session()->put('tmpfiles',$tmpfiles);'' and vice versa ''$tmpfiles = $request->session()->get('tmpfiles',[]);'' notice a nice feature of the ''get()'' method: we can pass a default value as a second argument which will be returned in case the session variable is not set. that's pretty helpful. Session variables are also available in blades by using the ''session()'' helper like above. <br>
+a specialty in laravel is, that we can **flash** data to a session. flashing means, that the data will only remain in the session for the next request. after that it will either be unset or we need to **reflash** to keep the flashed variables. to flash a variable to a session, we do the same as above with the ''get()'' function but now use a ''flash()'' method, that's it.
