CFSCRIPT Special Characters

[Wile E]

An external application posts a $ (%24) at the beginning of each querysting. I
am able to reference the querystring through normal cf tags, but not within
cfscript. Is there an escape character needed?



<cfparam name="$selected_rows.node" default="">
<cfparam name="$selected_rows.NodeAlias" default="">
<cfparam name="$selected_rows.IFDescr" default="">
<cfparam name="$selected_rows.DSN" default="">
<cfparam name="$selected_rows.FirstOccurrence" default="">
<cfoutput>#$selected_rows.node#</cfoutput>
<cfscript>
if (variables.Description eq "")
{
if ($selected_rows.node neq "")
variables.Description = variables.Description & chr(10) & "Node: " &
$selected_rows.node;
if ($selected_rows.NodeAlias neq "")
variables.Description = variables.Description & chr(10) & "IP: " &
$selected_rows.NodeAlias;
if ($selected_rows.IFDescr neq "")
variables.Description = variables.Description & chr(10) & "Interface: " &
$selected_rows.IFDescr;
if ($selected_rows.DSN neq "")
variables.Description = variables.Description & chr(10) & "Message: " &
$selected_rows.DSN;

}
</cfscript>

Actually, $ works just fine in cfscript. Are you using CF7?

The code you posted works except that a variable "variables.Description" is
referenced that doesn't exist.

Add <cfparam name="variables.Description" default=""> to your code.

If there is still a problem, please post the exact error massage.

I did have a cfparam for description (just didn't have it in my snippit). The
error is "Element NODE is undefined in $SELECTED_ROWS. " The error only occurs
when I actually try to pass something throught hte URL like this ---
test.cfm?$selected_rows.node="abc12345" As I test, I created another page with
the following code. It appears that CFPARAM is killing the variable?


<cfoutput>Before:#$selected_rows.node#</cfoutput>

<cfparam name="Description" default="">
<cfparam name="ActProbDate" default="">
<cfparam name="ActProbTime" default="">
<cfparam name="serial" default="">
<cfparam name="$selected_rows.node" default="">
<cfparam name="$selected_rows.NodeAlias" default="">
<cfparam name="$selected_rows.IFDescr" default="">
<cfparam name="$selected_rows.DSN" default="">
<cfparam name="$selected_rows.FirstOccurrence" default="">
<cfoutput>After:#$selected_rows.node#</cfoutput>

The error is that you cannot pass complex variables through the URL like that.
(It's not part of the W3C spec).
When the URL contains test.cfm?$selected_rows.node="abc12345", it doesn't
create a structure named URL.$selected_rows.

It creates a simple variable named URL.$selected_rows.node with the 2nd period
treated as a text part of the name.

If you want to be able to pass struct values through the URL, you will have to
convert each one. Add code like this above your CFParams:

<CFSCRIPT>
if (IsDefined ("URL.$selected_rows.node"))
{
$selected_rows.node = URL.$selected_rows.node;
}
</CFSCRIPT>

That works to use isdefined instead of CFPARAM. Thanks!!!! Like I said before, the other app is passing the URL that looks like that. I thought it was kind of strange.
