[@arpitachiddarwar5223]

Hi Dipesh, thank you so much for such informative video. However, if I want to clear the form once I click on the submit button and if everything is valid, what can be done in that case.

[@ironsand]

Loved your video! Just an observation, no dev should limit the maximum number of characters in a password, it's a security breach.

[@DipeshMalvia]

Just an example to showcase the validation.

[@ratiarahman8262]

Thanks for the video. I have learnt a lot from your videos. About the form submission, all the values should get submitted after fulfilling all the conditions. isn't it?

[@raivosulla4840]

Hi! Great video, really helped me alot. But could you please explain the purpose of useEffect in this code again. I dont quite get it since it works the same with and without the useEffect. Thanks in advance!

[@gudiwithahoodie8174]

Hi Raivo, here it's used just to keep track of when the form is filled correctly and to log the validated info to the console!

[@mayurghuge8846]

धन्यवाद।

[@alishadeo16]

I liked the tutorial so much. It was so easy to understand because of the way you explain it. I request you not to try a different accent. otherwise its superb. best ever tutorial I have come across in a long time.

Bhaiya how to validate form using bootstrap validation or jQuery validation on button click not onSubmit?

[@wifekbenromdhane1419]

thank you !

[@ranikumari9883]

Thanku

[@heatherherries9359]

Hi Dipesh! Thank you so much for this video! This helped me understand useState very well along with form validation. One question though, how do you get rid of the code that lingers above the form? I see it is coming from the initial values variable but have tried to remove it and nothing seems to work. Thank you in advance.

[@georgesword2012]

In the return, just remove tag and any content inside. Author used this aproach to show updated values of each fields on the screen instead of logging them in the console with console.log(), that's it.

[@a_maxed_out_handle_of_30_chars]

@@georgesword2012 thank you :)

[@rereroi]

i@@georgesword2012 i removed the pre tag but it showed error

That was useful, and thanks for github code!

Great explanation Dipesh .One question regarding css style where are the classes ui divider etc in the git repository?

[@flyflor599]

I found it from the last video ,ui semantic

[@abhis7478]

In if statement, why is it errors.username='username is required' but not key-value pairs ?

[@abheemk]

hey Dipesh, can you make a video on multi step form without material ui,

[@DipeshMalvia]

Don't have such plans but will think about it.

[@aayushgupta6914]

Isn't using setState better? Btw I am new to react and this was what the console was saying.

[@DipBeats_]

which library you are using for CSS ?

[@harshavardhanp683]

Very good and clear explanation. Is it possibe to do the form validation using class component. If possible, how? Thank you.

[@DipeshMalvia]

The modern way of writing React code is function component so I don't think I will able to a video using Class Components. Sorry brother!

[@harshavardhanp683]

@@DipeshMalvia No issues. Thank you brother.

[@mdnaushadali8241]

Anyone please help me to understand this line why we are checking keys values length of Object instead of doing this --- if(Object.values(formErrors).length ===0 && isSubmit)

[@smarttechinfo4512]

Sir, i have a question .Suppose I have a file input to upload. If anyone change the extension and upload it to the server. In that case how to validate that file before uploading... Eg. Suppose I have a file virus .zip , now I change it to virus.png and upload it to the server.. then how to protect the server from this kind of hoax image through validation...

[@panchalpranav7799]

It's a great video but also tell me how to store data in local storage
