Email Address Confirmation 1

[varnix]

One of the scripts I am writing uses the CFMAIL tag to send a confirmation email back to the user with their information.

Since this is on an internal intranet we have a list of all approved email addresses within our system.

Our email consists of first.last@domain.com - we have been able to pull the first.last out of the submitted form field using spanexcluding(form.email,"@&quot and then testing for a valid email address.

However, we also need to test the @domain.com portion to make sure that people spell it right. This has been an issue for us in the past unfortunately - people who can't spell the domain name, let alone their own name properly.

Thanks!

If it is the same domain name consistently you could use something like:

<cfset tempdname=#Left(form.email,12)# <!-- 12 is the number of characters in the domain name including the .com -->

<cfif tempdname = &quot;tek-tips.com&quot;>
pass form
<cfelse>
return to form to correct
</cfif>

This could also be done on the client side with javascript and an onsubmit event in the form tag.


Hope this helps The only dumb questions are the ones that are never asked

Thanks for the help, the only change I had to make was to change it from left(email,12) to right(email,12). Using left it gave me the username and not the domain name.

I didn't even know about those commands!

Thanks again!

Sorry for the mixup. Good catch though. The only dumb questions are the ones that are never asked

You could also use a regular expression:

<cfscript>
form.email = &quot;

first.last@domain.com

&quot;;

vRegXemail = &quot;^(

[

a-zA-Z

]

+).(

[

a-zA-Z

]

+)\@(

[

[

a-zA-Z0-9_.-

]

+)\.(

[

a-zA-Z

]

{2,3})$&quot;;

vFname = ReReplace(form.email, variables.vRegXemail, &quot;\1&quot;);
vLname = ReReplace(form.email, variables.vRegXemail, &quot;\2&quot;);
vDomain = ReReplace(form.email, variables.vRegXemail, &quot;\3&quot;);
vExt = ReReplace(form.email, variables.vRegXemail, &quot;\4&quot;);

</cfscript>
