In PHP, I know that if you echo or display a variable that
has not been defined, it will just run through it and display
nothing. However, in CF, I get an error when that happens. If have
about 20 variables that need to be displayed and need to know if
there's a way to have the code say, if these variables are not
defined, just ignore them. Possible? Thanks!
no, cf will always throw an error if you try to use an
un-defined variable.
you can use <cfparam> to give your vars default values
- if a var is not
defined, it will be set to the value you specify; if it is
defined, it
will not be changed.
