Allow only text and exclude numbers in text line fields

  • Hi!
    Could you please explain if there is a solution in Contact Form 7 to exclude numbers in text line fields? For example, in [your-name] field Contact Form 7 allow for default enter both – letters and numbers there. This creates a spam problem. It would be nice to be able to allow only text characters and restrict numbers for some text fields. Is there such a built-in feature in Contact Form 7?

    Excluding numbers will make no sense. If you are suffering from spams why don’t you activate spam protection?

    Dear Takayuki,

    Your plugin is great, but text field validation and antispam system are slightly different things. There is such a thing as Client-Side Form Validation. According to its logic, each text line field should allow a certain value. For example, the name field accepts only text, the phone field accepts only numbers. I want to implement this logic. That’s why I’m wondering if there are any built-in solution on the Contact Form side, maybe some hooks through functions.php. The fact that you can enter numbers instead of a name – I consider it a violation of the form logic and a violation of the security policy. Such form will not pass the pentest. I want, that CF7 users to be able to configure field validation according to security standards, not just enable the antispam system and block requests from a specific IP/User-Agent, etc.

    Best regards and thanks for your work!
