Re: Forms : Validating user input is integer

Hi tim, most certainly it can be done on the server side, it juts requires a round trip to the server is all.... i think it is .. if(!isinteger($input_var)): (check the exact function in the php manual) echo "this is an error (or whatever), press here to go back and correct your inpout"; exit; /* stops the script executing */ endif; HTH Steve At 3:05 PM +1000 5/4/01, boclair wrote:

I have a problem with a user input in a form required to be an integer, creating a variable for a mysql query. I have instances where integer, 0, is being typed as letter,o. The last discussion of validating the input was http://marc.theaimsgroup.com/?l=php-db&m=97207172003983&w=2 There it was suggested that the only way to validate the input was using javascript. I have a case where clients have disabled javascript. I tried fiddling with is_int($input) but of cause it does not serve this purpose. Does anybody know if such validation can be done server side or definitely must be done client side?
