Price validation - numeric only
Is there anyone who has applied validation on the "price" field to restrict user to enter numeric only?
By default, Classipress seems to be parsing whatever input to the "Price" field into numbers, so if a user inputted "300-400", it is displayed as "300400". It seriously affects the usability of the price range on the custom search.
What I want is for the user to get a error message if they have inputted any non-numeric value.
Can anyone please teach me how to do it?
Thanks a lot!
