Question

I have a form that has five fields that are all set to maxlength=”2″.

Basically, i want the only values that can be entered to either be a one or two digit integer, because calculations are performed on these fields before the values are stored in the database.

Is there any jquery that will not let a user even enter a value that isnt an integer?

Also what would be the best way to validate this with both jquery and php? I have found some ways of doing it, but i need to make sure its secure, avoiding characters, -2, .1 etc

---

SOLVED

For the php part i used

if(!ctype_digit($_POST['value']))

which only allows for positive whole numbers

And for javascript

 $('.inputQuantity').keyup(function(){ 
    this.value = this.value.replace(/[^0-9\.]/g,'');
});

which deletes any entry made into the input field that is not a number.

Both above work, although i think some people prefer to use focusout(function() rather than keyup(function() 😉
