The answer for your interview question: use "old()" helper in value attribute of input tag. eg: value= " {{old ('name of filed') }} "

[@TechPurush-2023]

Thanks.

[@TechPurush-2023]

But old does not work with password field, obviously bcos it's hidden.

[@darn2926]

A CSRF token is a unique, secret, unpredictable value that is generated by the server-side application and transmitted to the client in such a way that it is included in a subsequent HTTP request made by the client. Mainly used to make sure that nobody should be hack in without the a CSRF and is generally generated using pseudo-random number generator and is transmitted security is important between server and client in this case.

Your way of teaching is awesome. Hope, it will be a complete series. I hope you will show how to send and receive various types of data using Axios in Laravel.

[@mohammadazzam5265]

I loved your explanation well explained and nicely giving the information waiting for a series on Codeigniter 4, please thank you very much, sir

[@kaziovesh9798]

We use csrf token for security purposes like.. Laravel makes easy to protect your application from cross-site request forgery (csrf) attacks.......csrf token secure your application from attacker.. AM i right sir?

[@mohammedhusain6446]

What is meant by cross site request, can you explain plz.

[@finegap]

@@mohammedhusain6446 Cross-Site Request Forgery (CSRF) is an attack that forces an end user to execute unwanted actions on a web application

I like the way you explain it because easy to understand. Hope you will continue to make more videos ! I always support you

Laravel automatically generates a CSRF "token" for each active user session managed by the application. This token is used to verify that the authenticated user is the person actually making the requests to the application.

[@ashokbishwas]

A CSRF token is a secure random token (e.g., synchronizer token or challenge token) that is used to prevent CSRF attacks. The token needs to be unique per user session and should be of large random value to make it difficult to guess. A CSRF secure application assigns a unique CSRF token for every user session

[@aamirkhanmaarofi9705]

Use value="{{old('nameOfTheElement')}}" in order to remember the value of field even when the validation fails.

Hi there! In the validation you validate the filelds but can i get a specified one like $req->username, can i do something like this? nice vid btw

[@MonirulIslam-sg7oh]

Nice video. Can you show the how the old data can be back?

[@gyamfijohn3066]

reason for adding @crsf to your form is ; Laravel's CSRF protection mechanism helps prevent CSRF attacks by generating a unique CSRF token for each user session. This token is added as a hidden field in every form generated by Laravel using the @csrf directive. When the form is submitted, Laravel verifies that the CSRF token matches the one stored in the user's session. If the tokens don't match, Laravel will reject the request, preventing potential CSRF attacks.

[@mhsmartgaming2708]

Then when the form does not pass the validation I need to show the old input, so that user does not loose what he has already input. So I need to have a way to display old data like: value="{{old('title')}}"

[@JasvirSingh-fd6fp]

thanks sir.

[@super-legend]

Csrf token is used for preventing violation of cors policy

[@freetimespot7218]

when I try to make a validation on update it takes the same values for the insert, but I wanna make them different validation!

[@graham11545]

not sure what is the question?

[@domingo9037]

Why I keep getting error like this syntax error, unexpected '=>' (T_DOUBLE_ARROW) on the validation

[@MajidKhan-lh9cl]

How to return validation error without resetting form? because if you have a form with multiple fields a single validation error will reset the whole form.

[@csstudies1393]

gd question

[@aliraza9511]

you will have to use the attribute on input field which is onChange event -> you will pass the validation method to this event. so on every change in input field -> validation method will get called and it will return you error as you type....

[@rahulgarnayak9400]

Broda , I have few doubts, 1. What is all() and any()?? 2. All of sudden you are declaring $message , Whats the use of that , Whether it is predefined ?

[@flyingfox4262]

These r the predefined methods of errors class, if u know object-oriented form thn u can understand

[@sengwatrongrat1630]

Hello Sir and every body , I have a doubt , what is the any() function ?

[@graham11545]

ok so $errors returns an erorr object and the method any returns a boolean if there is any error

this video is not available in your hindi series

[@rishabhsharma775]

I was enjoying your videos and watched till middleware but NOW I realized that it is BAD IDEA to continue on your video...... Becoz you don't teach full points but instead keep hidden important point to ask as interview question. For example, in this- vid you didn't tell how to save input value from reload. You should have told this also in your video but instead you choose to play nonsense of interview question.... If we have to search by ourselves then whats the point of watching your videos. I was watching video to get complete information about laravel, not partial. So I have switched to other youtube channel who gives complete information unlike you. I just feel like to share this with you so if can think about if u wanna keep this way continue in you upcoming vids.
