Since there are different fields that can be updated, some of which are available in some requests, and sometimes there are not. This is especially useful when dealing with updating the model. If I have sensitive fields, then there are a couple ways to close loose ends.įor example, in the form request, I could take advantage of the authorize method public function authorize () Spelling them all out one by one feels like so much pain. I use $request->all() a lot, especially because it has a way of cleaning things up pretty well.Ĭonsider a scenario where there are so many possible fields that can be updated for the user, some of which I don't even care to validate. I really do think that the key thing here is "moderation" and using with "caution". If you use the Form Request class for the validation, you have the rules() method there: This is happening because $request->all() doesn't filter or validate anything, it's just literally all(). Not that hard to write a script to automate trying all the possible options. So, to "hack" the system, all I would need is to guess the non-visual database fields: it may be called is_admin, it may be role_id, just role, or whatever else. Guess what: the is_admin will be successfully saved, and I will successfully register myself as an administrator, without anyone's permission. If you have a buttressing or conflicting view of anything here, please reach out to me on Twitter.See that is_admin column? It is used to assign the administrator role, and that field should be filled only by other administrators, in some other form than the registration, in a separate admin panel.īut what if I try to call that registration to submit by adding a hidden field called is_admin, directly from my browser, like Chrome dev tools, clicking Inspect? There will be an advanced series of this guide coming soon and it's going to contain:Īuthorizing Form Requests(Restricting and authorizing certain users access rights) Other articles will be published to properly explain other concepts like models, routes, migrations, controllers, etc. To make this article very comprehensive and forward, I didn't give a detailed explanation to anything asides Form Requests. Guess what?□The entire code for this is open source here on my Github. Woah□□! This has been a thrilling and exciting journey for me, I hope it was for you too.□ To verify if our Form Request Validation works I didn't fill in anything for email and it returned the output of my error message where email is required saying ''Email is required".Ĭongratulations on your new knowledge acquisition!□□ So I accurately filled in the required fields in their valid format respectively and it returned the output of a JSON response saying 'Registration Successful'. PS: We will have to set our header to accept JSON and if you'll be cloning my Github repository, I already created a middleware for that. In summary, if a user registers successfully and all his input information is stored then a JSON response is returned.įinally, let's test to see if this really works.□ To create a controller class, you may use the make:request Artisan CLI command:Įnter fullscreen mode Exit fullscreen mode I'll be creating a basic User Registration API with Form Requests Validation, so follow through carefully.□ I consider Form Requests an awesome Laravel feature and it will be great if many engineers can adopt it. ![]() One more benefit□ is that you can also customize your validation error messages. They also aid the reusability of any validation logic in the controller. They allow you abstract validation logic from the controller to a single class. ![]() ![]() Now there is absolutely nothing wrong with this method but think about scenarios where you need to perform a validation logic more than once, this is one advantage of Form Requests.įorm requests are custom request classes that encapsulate their own validation and authorization logic.ĭue to this, you really don't need to clutter your controller with any validation logic. The prominent way of validating data requests in Laravel is by using the validate method or validator facade in our controller like this: I'll be doing a short guide on how to use Form Requests to validate data requests in Laravel As a back-end engineer, dealing with forms is almost inevitable.
