it's a no brainer, you just do it and it works.

[@maheshlowe907]

Highly recommended video series. BTW what are the formaters used to php, blade, html formatting?

[@mosesegboh]

Hello, great tutorial, please how can i stop the form from deleting user input during validation??

[@nomankhan-st2dp]

you are the best

[@ProgrammingwithPeter]

You didn't talk about custom requests...which is a feature of laravel and it is recommended since you can extract that logic outside of the controller

[@codehunter1366]

Wow. thank you for sharing its a big help.

[@elx5841]

Thank you for your helpful videos. I have one question regarding the shortened version of the create: method you invoked through the Service Model: $data = request()->validate(['name'=>'required|min:5:max:10']); \App\Service:create($data); What if I have a variable that I need to insert into the database that will not be coming from the POST? EG: $data = request()->validate(['name'=>'required|min:5:max:10']); $data['value'] = 'THIS IS A STATIC VALUE'; \App\Service:create($data); How do I achieve this?

[@adam192021]

The BEST as always!

[@Aecy]

You can do FormRequest for the validation, it's better (for me and more clean).

[@CodersTape]

I agree with you in that adding that abstraction is nice on larger forms, however, it's not as straight forward to understand to a newcomer to Laravel. Better to keep it simple until ABSOLUTELY necessary.

[@Aecy]

@@CodersTape Of course, you're right but I did not say it was the best solution for beginners :)

[@nataliapalweski2072]

on showing error why form input field is reset to empty? according to Laravel documentation it is saying "Laravel allows you to keep input from one request during the next request. This feature is particularly useful for re-populating forms after detecting validation errors. However, if you are using Laravel's included validation features, it is unlikely you will need to manually use these methods, as some of Laravel's built-in validation facilities will call them automatically." I don't wanna use old() method

[@randomguy5922]

i am using maatwebsite excel package, is there a way to import data and check validation on some specific fields, if any record fails to match validation, record the whole rows in a report excel file with the error message or red color in that field text which are not proper (the reason why validation failed) and then finally after full import have and option to download error excel file. So that we can correct the fields and upload that file again.Do you have any tutorial like this. I will be highly thankful if you guide me how to do this, i have tried to read the maatwebsite excel package documentation, but it is not very much clear to me.

[@ShahinShateri]

what if we want the text field's name to be "serviceName" but the validation error message shows "The service field is required."? how can we do that?

[@silvijabojkovski5053]

It says that $message is not defined.... What should I do? I use version 5.4.36

[@AmeerulIslam]

I think you should have said that this line: "protected $fillable" and "protected $guarded" are default properties in class Model and we are overriding it. Isn't that's what we're doing here?

[@zombiesbyte331]

I've never understood the csrf token thing. Wouldn't you just gab the value before sending over a form submission from an external site? It only protects if you don't grab that freely and readily available token. i.e. coderstape.com login form has this token ciIWBQoEmDqP30fHTVvdvK6lIg7advnSKgzQtior, now I'd be able to submit a form using this token. I'd need to grab the next token generated to do it again but my point is; how does this stop or hinder anything, a script would quite easily grab these tokens for me on each round of cross-site submissions?

[@vigilantezack]

I'm not sure I understand the mass field creation protection thing. If the fields were not in the submitted form, or fields don't exists in the DB, what's the problem?

[@CodersTape]

data injection is the short answer. long answer let's imagine an example where you have a field in the user's table to determine their subscription level. If a user was able to figure that out, they could pass in their arbitrary fields into your database by modifying the form in their browser.

[@vigilantezack]

@@CodersTape yep I can see that. But there must be cases where updating a field like that would be proper. So then I assume you can bypass that setting and updated it just the same? Like when a user first signs up you'll probably set that field for the first time.

[@younesmarouf2200]

Hey i'm a beginner i'm watching your videos and i like them i just have a question how to prevent multiple submitting in one button ex : when i click add customer twice all information duplicate in my db and again thank you for your tutorial

[@kiefferganza169]

does laravel validation only work with eloquent models?

[@CodersTape]

Request validation has nothing to do with eloquent. It just validates the request, not the model.

[@kapa4208]

Can you please explain to me a bit about namespace, what's the difference between "\App\Model\" and "App\Model"? I saw Jeffrey uses "App\Model" in the Laracasts tutorial. So I'm not sure which convention to use.

[@CodersTape]

The difference has to do with the current file that you’re in. What I mean by that is that if you’re in a file that has the namespace App already. Here’s what would happen. \App\Model would stay as \App\Model but App\Model would tag on to the already existing namespace and give you \App\App\Model which is not what you want.

[@kapa4208]

@@CodersTape Ahh I see. Thanks for the answer, I'll stick with the \App\... convention.

[@dgloria]

@csrf was never mentioned in any Laravel tutorials I watched so far.

[@romimaximus]

hmm.. after i did add the new dedicated controller, laravel couldnt find my layout, views and nothing else and gave a big error "ReflectionException" and "Kernel does not exist'"...i couldnt fix it ..and i had to remake my whole code again....its frustating..!!! i dont know what happen...!! lol..

[@hiteshaloney]

How to work with ajax calls and dynamic forms in laravel ?

[@itsumarejaz]

Is there any naming convention for Controllers? In freeCodeGram Project, controller names were ProfilesController, PostsController, as there can be many profiles and posts. Similarly, services can be many, so shouldn't ServiceController be named ServicesController?

[@CodersTape]

There was a change in Laravel convention into singular controller names so I made the change as well. Up to you, just pick one and stay consistent with that

[@itsumarejaz]

@@CodersTape Sure

[@sezohessen7485]

Note: if there is any error doesn't logic use command php artisan optimize

[@sunwavesonmars7588]

i can create but cant update it , weird

[@alfredocarreon4449]

how to customize a validation error message? ex: a name that needs to have a minimum length of 30 (rule would be min:30) instead of "The name must be at least 30 characters.", i want it to be "Name length too short. (Minimum of 30 characters)."

[@marcinb8038]

you have to edit validation.php in resources/lang/en as it is stated in documentation

[@createforpeople]

But request validation will be better way ;)

[@caterpilar]

Don't forget to turn off fields of created_at and updated_at, if you don't need them in table. To do that in your model write class Cl_name extends Model { public $timestamps = false; }

[@nac9880]

and remove $table->timestamps() from migration to prevent the creation of these fields in first place

[@sangeetha1421]

Source code please

I’ll get it posted up on Github under the Coder’s Tape repo.
