number field validation

  • Hi,

    I have added number validation field to a form.
    What I understand is that should only accept numbers, but it accepts letter “e” “.” “,” ?

    How to have it valiting properly?

    Added CF7 to 2 different sites, by both of them it happens the same when validating numbers.

    Cheers

    Contact Form 7 uses is_numeric() to find whether the given value is a number, thus letters “e” and “.” are accepted. You can customize the result using the wpcf7_is_number filter hook.
