Question : CF - Form checking for errors with form action

I have a form that checks for errors before submitting. The problem is when I add the needed <form action="includes/postAAEmail.cfm" the error checking no longer happens but if that action is removed then it checks for errors. Any help is appreciated.

Answer : CF - Form checking for errors with form action

> how does that code get triggered

when Coldfusion sees a CFINCLUDE, it stops processing the current file and processes the included file before proceeding.

You can take this...

<cfif isDefined("FORM.AAsubscribe")>
<cftry>
<cfset form.email = trim(form.email)>
<cfif len(form.email) eq 0 or form.email is "Your Email">
<cfthrow message="Please enter your email address">
<cfelseif listLen(form.email,"@") neq 2 or listLen(listLast(form.email,"@"),".") eq 0>
<cfthrow message="Invalid Email address">
</cfif>

<CFQUERY NAME="GetEmail" dataSource = "#application.datasource#">
SELECT Email
FROM SubscriberTestEmailGroup
WHERE email = <CFQUERYPARAM VALUE="#FORM.EMAIL#" CFSQLTYPE="CF_SQL_VARCHAR">
</CFQUERY>
<cfif GetEmail.recordcount gte 1>
<cfthrow message="That email is already registered to receive the newsletter">
</cfif>

<cfquery dataSource = "#application.datasource#">
insert into SubscriberTestEmailGroup (email)
values ('#form.email#')
</cfquery>

<cfcatch>
<cfset strError = cfcatch.message>
</cfcatch>
</cftry>
</cfif>

and turn it into this....

<cfif isDefined("FORM.AAsubscribe")>
<cftry>

<cfinclude template="SendEmail.cfm">

<cfcatch>
<cfset strError = cfcatch.message>
</cfcatch>
</cftry>
</cfif>

This would be the contents of SendEmail.cfm


    <cfset form.email = trim(form.email)>
    <cfif len(form.email) eq 0 or form.email is "Your Email">
      <cfthrow message="Please enter your email address">
    <cfelseif listLen(form.email,"@") neq 2 or listLen(listLast(form.email,"@"),".") eq 0>
      <cfthrow message="Invalid Email address">
    </cfif>

  <CFQUERY NAME="GetEmail" dataSource = "#application.datasource#">
      SELECT Email
        FROM SubscriberTestEmailGroup
      WHERE email = <CFQUERYPARAM VALUE="#FORM.EMAIL#" CFSQLTYPE="CF_SQL_VARCHAR">
    </CFQUERY>
    <cfif GetEmail.recordcount gte 1>
      <cfthrow message="That email is already registered to receive the newsletter">
    </cfif> 
    
    <cfquery dataSource = "#application.datasource#">
     insert into SubscriberTestEmailGroup  (email)
     values ('#form.email#')
    </cfquery>
