[Plugin: Contact Form 7] mandatory number of characters in a field?
I’ve been looking in faq and other posts in this forum but not founded an answer. Is it possible to have a mandatory number of characters in a text field, using this plugin?
I need to make the submit button disappear (and have an error message) if user don’t fill all the character needed in that field (i.e.: like cc number, we know it’s always 12 digits, why allow to send a form with 11 digits?)
looking forware to hear from you! thanks!
