Check for Numeric Value???

[dlithehil]

So, I asked some of my friends to break my site. And boy did I get my wish.

Anyway, one goofball put a non-numeric character into the shop's quantity space to buy things and got this result.

Is there any way to check that a character entered is numeric? I would also need to throw this into my higher/lower game...

I'm super late to the party here, but in case you still need it, for the shop bug, go to the shop controller file and add this at the top with the other namespace lists:

use Resource\Exception\InvalidActionException;

then go to the purchase function and after this:

if(!$mysidia->input->post("buy")) throw new InvalidIDException("global_id");

add this:

if(!is_numeric($mysidia->input->post("quantity"))) throw new InvalidActionException("Quantity must be a valid number");


adding a check using is_numeric for any post data like the above example can be used to stop non-numeric input on any controller page.
