The order form quantity field accepts any character, numeric or not.

If you enter any non-numeric character in the quantity field on the order form, it places qty. 1 of the item in the cart. Can this be set to not accept non-numeric characters?

Correct, there is no client side enforced validation. Add to Cart will default to a quantity of 1.

You have a couple of options:

1) Restrict quantity input to numeric only. Options:

a) JavaScript. Example : http://jsfiddle.net/lesson8/HkEuf/1/

b) Qty DropDown, using the built-in Restricted Quantity feature.

2) Add server side validation, so that once the form is submited the value will be validated, and any error reported back to the user on the product page.

3) Both 1 & 2.

If going with #1, I suggest the use of JavaScript, like the example given. An HTML5 attribute can be used, but some older browsers will not support that feature.
