Using Validation Regex To Limit Email Address Domains

  • Resolved FrankJohnson

    I’m trying to use the Validation regex setting associated with the default email field (which I have set as a text type field) – to prevent the form from working unless the email address entered is in a particular domain.

    I’m not an expert at Regex, but I thought that using straightforward text without variables would work for my purpose.

    So I thought I could enter this in the Validation regex field:

    @domain.com

    and that people who entered an email address that was not in the @domain.com would see Regex fail message. This is working.

    The problem is that if someone enters an email address such as [email protected], they still see the Regex fail message.

    Can anyone help me understand what I might be doing wrong?

    Thanks in advance for any help anyone can offer – I really appreciate it.

    Sincerely,

    Frank Johnson

  • Hi Frank Johnson, in regards to validation regex this is what @mike Challis has in his website about it…

    Validation regex:
    Use a regular expression to validate if form input is in a specific format. Example: If you want numbers in a text field type but do not allow text, use this regex: /^\d+$/ Can be used for text, textarea, date and password field types.

    The above should give you an idea of how to implement this feature in the plugin.

    Kind regards

    Thanks mbrsolution. I did see that in the instructions for fields, but it doesn’t help me for the specific use I’m trying to implement (preventing submission of the form unless the email address is in a particular domain).

    If I put @domain.com in the field, I would think that [email protected] would test successfully against it. I ran it through a regex validator and it matches. But as I said, I’m not a regex expert, so I’m sure I’m doing something wrong.

    Thanks,
    Frank

    Hi Frank try the following URL it might help you.

    Thank you

    this one should work. replace gmail.com with the domain you want
    be sure to put a slash in front of the dot in the domain name

    /^[-_a-z0-9\'+*$^&%=~!?{}]++(?:\.[-_a-z0-9\'+*$^&%=~!?{}]+)*+@gmail\.com$/iD
