Variables within a <![CDATA[ Tag

Hopefully I am missing something easy here.
TS 6.5 on Solaris
I have no problem referencing variables in a PT template that are defined outside of the CDATA tag using: iw_value
Thinking I could reference this the same way inside the CDATA tag is giving me problems.
I am loading dcr's into one PT Template and the variable used within the load tag is not recognized.
Currently I have just setup a static values in an array for testing.
What am I missing here?

my @dcr_files_to_include = ("05052006evening.dcr","05052006morning.dcr","05172006morning.dcr","999999morning.dcr");
my $filelocation = "templatedata/tablecontent/escript_table_4col/data/capacity/operationally_available/";

 foreach $nonexpired_dcr(@dcr_files_to_include) { <iw_load_dcr file= '{iw_value name ="$filelocation"/}{iw_value name ="$nonexpired_dcr"/} ' global='t'/> } foreach my $index ( iwpt_dcr_list( 'dcr' ) ) { <iw_iterate var='index' list='dcr' iteration = "i"> <iw_if expr = '($i % 2) eq 0'> <iw_then> <tr bgcolor="#FFFFFF"> </iw_then> <iw_else> <tr bgcolor="#CCCCCC"> </iw_else> </iw_if> <TD ALIGN=LEFT VALIGN=CENTER ><iw_value name = 'index.notice_type' /></TD> <TD ALIGN=LEFT VALIGN=CENTER ><iw_value name = 'index.posted_date' /></td></TD> <TD ALIGN=LEFT VALIGN=CENTER ><iw_value name = 'index.effective_date' /></td></TD> <TD ALIGN=LEFT VALIGN=CENTER ><iw_value name = 'index.subject_title' /></td></TD> </iw_iterate> }

Sorry seems Like pasting the code did not work so well. I have attached the tpl this time. Thanks!!

It appears you forgot to attach it...

Inside your iw_perl tags, you should be using the perl sub routines provided like iwpt_dcr_value and iwpt_dcr_list. You can read more about these in the documentation. You can't use the tag syntax within the iw_perl blocks.

I would use this for getting variables that are within the PT ? I was thinking that this was just used for grabbing values out of dcr's that have been made available to the PT.

Well, if you're in an iw_perl section, you don't need to do anything to access the variables, just reference them directly.

This was my thought but this does not apply when you are within a CDATA TAG
For instance:
If the below code were within a CDATA TAG I would think I could just use iw_value to get the value of $nonexpired_dcr, but that does not work. I have looked at the manuals and online documentation for iwpt_dcr_value and am not sure how to contruct that. THe Iw_load_dcr should have <> tags around it

foreach $nonexpired_dcr(@dcr_files_to_include)
{

iw_load_dcr file= '{iw_value name ="$nonexpired_dcr"/} ' global='t'/

}

As I said before, within an iw_perl block, you reference it directly, no iw_value, no anything, just use the variable as if you were coding straight perl.

jbonifaci

Also, within an iw_perl blick, you sould be using the iwpt_load_dcr function. You can NOT use any of the iw_ tags within an iw_perl block, you must use the perl sub routines provided. Please read the manual about this, or check the manual on your server at:

That is where I was making my mistake. It was referenceing the perl var within the iw load dcr tag that was the issue. I moved the loading out from the CDATA tag and used the iwpt_load_dcr. Below is a working version two load dcr's into the PT from an array. Thanks for beating that into my head!!!! Hopefully I have that straight now.

my @dcr_files_to_include = ();
foreach $nonexpired_dcr(@dcr_files_to_include)
{

iwpt_load_dcr($nonexpired_dcr,'docroot','t');

}

<iw_perl>
my @dcr_files_to_include = (); 
foreach $nonexpired_dcr(@dcr_files_to_include)
{
    iwpt_load_dcr($nonexpired_dcr,'docroot','t'); 
}      
</iw_perl>

Is it safe to assume that there is other code that exists between the first and second lines of code shown above?
If not, this code isn't going to do too much since there isn't anything in

@dcr_files_to_include

. Also, you'll probably want to assign the result of

iwpt_load_dcr()

to a variable that you can use throughout the rest of your code, otherwise it isn't very useful.

Yes for the sake of the post I have just removed the values in the dcr_files_to_include array. Good point on set a var for the dcr. Thanks!!
