How to stop users entering comma's into address fields

[petsupplies4u]

Hello Everyone, Looking for some assistance to stop users from entering comma's into the address fields, I know I can code the "[a-zA-Z]" into the code but I need help finding out just where abouts to add the code. Cheers

And why do you want to stop shoppers using commas in their addresses?

[petsupplies4u]

Hello Strelitzia, The main and only reason to restrict the customer entering commas into name and address fields is when the order data is exported to either MYOB of a third party label or reporting program the commas can play havoc with the .txt file formatting. I'd like to restrict the entry to A-Z a-z 0-9 - . / only.

Cheers

Use str_replace if you want.

I don't know about restricting entry, but you can always take the entered value and delete every comma, or swap for a space, before storing/using.


Yes, with str_replace(',',' ',$address)

Hang on - @petsupplies4u, are you sure your order exporting program doesn't handle this? Typically fields will be enclosed in a value (like quotation marks, for example) so that commas within fields are ignored.
