[Zope] filename property of variable

[Thomas B. Passin]

Laurie, I think this might be what you want.  At least, it will let you
access each (unknown) form variable by name and get its value.  The slightly
odd expression "_[_['sequence-item']]" gives you the value because the
variable name is sequence-item,  if you do it like this.

<dtml-in "REQUEST.form.keys()">

    <!-- Show <name>:<value> -->
    <dtml-var sequence-item>:<dtml-var "_[_['sequence-item']]">

    <!-- Apply "if" test to see if variable has a value -->
    <dtml-if "_[_['sequence-item']]"> (passed "if" test)</dtml-if><br>

</dtml-in>

Try that on your form and see if it shows you the filled-in values.  It does
on my test form.  If you can render them, you ought to be able to do
anything else you want.

Cheers,
