Which language is better to validate forms ?

Question

Guys, which language do you recommend for validate forms, JavaScript or PHP ? I would like too creat a register sistem, but i need to validate too.

Answer 1

I use both as every other web developer. Here are some examples:

1. Username must be at least 3 characters long.
Use Javascript. It can handle it and it's the fastest way.

2. Username must be unique.
If you store usernames in a database (MYSQL, I Postgresql and similar), the most effective way of validation will be with PHP.

3. Username must contain only Latin letters.
Javascript has a solution to this.

Basically, if validation requires comparison to database values - use PHP. If it doesn't - use Javascript.

P.S. Anyone can take JS code from your website, because it is public. But no one can replace your code with theirs. It requires access to your server.

Answer 2

✅In my opinion it depends, however you can use for client side validation javascript and for server side validation you can use php.

Answer 3

Better is all questionable.
For less complex experience, i would say PHP. But if you have some experience on JS, doing it at Node may sound better for you

Answer 4

I think js is better among all because it is better to validate the form on the local browser rather than sending query to the server...and then validating the details..

Answer 5

I think PHP but this is not an expert opinion.
