Forum OpenACS Q&A: Help with List builder

Hi,

In the code below, the page expects "owner_id" and "url". The resulting page displays a list with two columns: title, and entry_date. I want both columns to be sortable, so that clicking on the column header will sort the rows in the reverse order. The problem I am having is that since the page expects "owner_id" and "url", I get an error, since the sortable headers do not export these variables. How do I export these variables so that they are passed on to the sorted page?

Thanks,
Nick.

}

# Maybe add category to listing too.                                            

template::list::create \
    -name entries \
    -multirow entries \
    -elements $elements \
    -html {width "100%"} \
    -orderby {
        title {orderby {lower(be.title)}}
        entry_date {orderby entry_date}
    }

db_multirow entries entries {}

ad_return_template

i think the list builder does not support that. you can add a parameter "pass_to_urls" to proc "ad_proc -public template::list::create". add the parameter "pass_to_urls" and the following code

if { $pass_to_urls != "" } { set list_properties(filters_export) $pass_to_urls }

right after the part

# These are defauls for internally maintained properties
array set list_properties { ... }

then you can pass properties to all of the urls via

list::create \
-name "xxx" \
-pass_to_urls {var1 var2 var3}

hope that helps!
