One-Page Checkout [Support Thread]

[linuxguy2]

Hi,

PHP 7.1
zen-cart-v1.5.6a-01042019
[CloneClassic Template]
one_page_checkout-2.0.5
extra_field_on_customer_sign_up_0
Several core mods.

Been searching all morning and can't find a solution.
Need to validate some numeric and email fields (Phone Number, Fax, 777-666-6666), (Zip Code 77777) and (email [email protected]) also need add "re-enter PW" on the registration page. (Please see attached)
Have set the minimum/maximum length values but need more control as in some cases the bots are bypassing my Re-Captcha.

Thanks for Your Time!!
