Don't validate anything with JavaScript what you can validate with PHP. Just don't.

 

Edit: ... Of course, I'm implying that your JavaScript implemntation is not found on your server. If it was a server-side implementation of JS, then go ahead. If you mean the client-side JS with the Document Object Model, then forget about it.

I think he means checking if the user actually input anything in the field when they press submit. If they didn't input anything it shows an error message on top of that field. This would be done with JavaScript, not PHP.

Right.

 

That is easy, of course.

 

I would need to see the actual form you have created for that, MathiVel.

I distribute a contact form with jquery, ajax and php validation methods along with HTML5 attributes for certain browser validation.

You can take some clues from it if you want, or use it if you also want.

This can be accomplished with PHP. You would just re-display the form if there were errors, populate it with the information submitted, and display the necessary error notices.

 

The only benefit of using a client-side solution, like JavaScript, is that the page doesn't need to be reloaded before the errors are displayed. JavaScript could display the errors on the fly. Just be aware that JavaScript can be turned off, so it's a good idea to also validate using a server-side solution like PHP.

Yes but its always good to be double-careful Plus if you don't use JS than it isn't very interactive and it keeps it basic.
