Jered, the following is a working example from one of our
application.cfm pages that submits to itself. If the form.username is
not defined, it sets showUNameHelp to yes, then in the html part of the
template it points to an invalid username error. Same thing for
invalid password error. If you have any questoins after digging
through this, let me know.
<cfif not IsAuthenticated()> <!--- User is not authenticated --->
<cfset showLogin = "No">
<cfset showHelp = "No">
<cfif IsDefined("form.username") and IsDefined("form.password")>
<!--- The Login Form was submitted --->
<CFPARAM NAME="Client.username" DEFAULT="#form.username#">
<cftry>
<!--- Try to authenticate the user --->
<cfif form.login is ''>
<cfset showUNameHelp = "Yes">
<cfelse form.password is ''>
<cfset showPassHelp ="Yes">
</cfif>
<cfauthenticate setcookie="Yes"
throwonfailure="Yes"
securitycontext="blah"
username="#form.username#"
password="#form.password#">
<cfcatch type="Security">
<cfset showLogin = "Yes">
<cfset showHelp = "Yes">
</cfcatch>
</cftry>
<cfelse> <!--- The Login Form was not submitted --->
<cfset showLoginHelp = "Yes">
</cfif>
<cfif showLogin>
<cfset url = "#cgi.script_name#">
<!--- Store the page they are on to return to it after
authentication --->
<cfif cgi.query_string is not "">
<cfset url = url & "?#cgi.query_string#">
</cfif>
<cfoutput>
<html>
<head>
</head>
<body>
<cfif showUNameHelp>
<font>Invalid Username</font><br><br>
<cfelseif showPassHelp>
<font>Invalid Password</font><br><br>
</cfif>
<form action="#url#" Method="post">
<table>
<tr>
<td class="name">Username:</td>
<td><input type="Text" name="username"></td>
</tr>
<tr>
<td class="name">Password:</td>
<td><input type="Password" name="password"></td>
</tr>
<tr>
<td colspan="2" align="center"><br><input type="submit"
value="Login"><br><br><br></td>
</tr>
</form>
</table>
</cfoutput>
<cfabort>
</body>
</html>
</cfif>
</cfif>

Rooms with angular corners will only encourage you to be cornered in life. Lessen the
danger by stapling pickled beets or meringue to the apex of the corner.
