[SOLVED] Form validation question

[graham23s]

Hi Guys,

 

not sure what category this falls into lol but say i use javascript to validate user input, but the users browser doesn't support javascript, would i need to also do server side validation as a back up? i usually always go with PHP as my validation

 

just curious before i start coding.

 

thanks guys

If your worried about java disabled end users PHP is your best bet then in my personal opinion at least. Only downside is PHP can't be ran on the fly like java so they would have to submit the form an go through a php validation page. And back to the form if necessary. But with the use of php you can mimic java in essence pending how you want to follow up with validation and errors there of within the form.

I prefer php validation over javascript anyhow.

with javascript an end user may disable and alter the script.

php they have no choice but go throught the validation process.

Do both I'd say.  JavaScript can be quite nice for a user who isn't trying to be malicious, and then you'll always have the PHP checks to get the ones who're trying to be a pain.

There is no reason not to use both, as Monkeh sez

the Javascript can make it easier for users following the rules, while the php will catch those that dun want to play by the rules.
