Hi there,

I want to apply an email validation feature to my survey, I came this link [ docs.limesurvey.org/Using+regular+expres...vey#Email_Validation :] which gave me this /^(\w[-._+\w]*\w@\w[-._\w]*\w\.\w{2,3})$/ but I am not sure where to put it.

I tried putting it the the condition editor of my questions, but it ended up deleting the following question. What do i do?

Hello

Bye

Thanks Ben. I have one final question. Is there a feature to make sure that the email address entered is correct (e.g. if there is a spelling error, or if the email is no longer active)

No this feature only checks if the format is valid...
You may previously use an online email validity checker like this one (in french)

Hello,

You can use some PHP script with ajax, but it's very difficult to be sure that a email exist and is valid.

What can be done before sending:
- Check the email have correct caracters
- Check if domain exist
- Use the smtp server in your server to check if the user exist (hardly part)

Don't work:
- check denis <AT> sondages.pro (redirected to contact <AT> sondages.pro) : broken.
- check sondages.pro <AT> belar.gsill.net (direct user at a server: must be allways good): broken.

There is no real good way to validate an email except directly test to send a email with a smtp server.

I think we can use a script like this one: www.devshed.com/c/a/PHP/Email-Address-Verification-with-PHP/5/ (but remove the check MX record, a server cab accet mail without this.)

Maybe ....

Hi Denis,

Thanks for all this information. I am sorry to say that I have no idea what you are talking about. I do not know how to write or use scripts.

This /^(\w[-._+\w]*\w@\w[-._\w]*\w\.\w{2,3})$/ helps to make sure that any email address entered ends with '@xxxxx.com or .ca', but if the address is not spelt correctly or invalid, it does not flag the email address as incorrect. I was wondering if there is a simple way to do this, because it is through the email address entered that I will be sending the honorarium to. Thus it is not up to me to validate the email address, it is up to the participant. I want to make this step as easy as possible for my participants when they are completing the online survey.

Thanks,
Nkem

There is no way to detect a typo. When using a regular expression, you can only check certain syntax details.

The best way to prevent typos is to use an additional email confirmation field. This blog post shows different examples:

can this be applied to one field in a "Multiple Short Text" type of question?

I would like to thank everyone for their help. It turns out that the version of LimeSurvey I have does not have the setting to verify the email addresses (the question validation equation slot) . I can validate it, but can not verify it. So I have just asked my participants to re-enter their email addresses, and hope that there will be no mistakes this way.

docs.limesurvey.org/Advanced+question+settings#em_validation_q . then go to this tab em_validation_q

Yes, if you use the subquestion validation. See manual and the blog post link for more information.
