Variable isDefined AND equals ????

[scullen81]

What is the correct syntax to say "If the variable is defined and the variable equals x"??

I have this, but it is not working:

<cfif IsDefined("element") and element eq "person">

adflgkjhdslfgjkdflhs

<cfelse>

adflgkjhdflg

</cfif>

Not sure what kind of results you are getting but... that looks correct. Off the cuff, the only other thing that I can think of that might cause some issues is if you have any other variables that share the same name.

If so make sure you explicitly define the scope in your conditional. i.e. isDefined("variables.element") and variables.element eq "person" etc.

Always scope your variables. Your code will run quicker (because ColdFusion wont have to check what it is first), be easier to read and cause you less problems in the long run.

In what way is it not working?

In addition to the suggestions above, I think you want single quotes around 'element'.

I would tend to do this like so:

<cfif IsDefined('element')>
<CFIF #trim(element)# eq 'person'>
Do something when it equals 'person'
<CFELSE>
What to do if it does not equal 'person'
</CFIF>
<CFELSE>
What to do if 'element' is not defined
</CFIF>
