syntax for passing attribute value to simple acl function

I'm having trouble figuring out how to pass an attribute value to a simple acl function that formats and returns the value to save it to a variable. The attribute is "revdate" and the eic is "cmm"

<e-I-c gi="cmm>

...

<att>

<specval attname="revdate" attval="#ANY">

<fillval attname="myfuncs::format_date" attloc="system-func" fillcat="savetext" fillchar="conrule">

<charsubset>

<savetext textid="issuedate.txt">

</charsubset>

Plus I know I'm not declaring the function correctly:

function format_date(window,oid)

...

local date=oid_attr(oid, ?);

...

Any help is appreciated.

    Hi Caroline,

    It doesn't need to be that complicated.

    In the FOSI:

    <fillval attname="myfuncs:formatdate" attloc="system-func" fillcat="savetext" fillchar="conrule">


    The following ACL gets the attribute value using oid_attr and oid_current_tag. Then you can use substr to format the string.


    function formatdate(window,oid)

    {

    $d=oid_attr(oid_current_tag(),"revdate");

    ...

    return ...;

    }


    If you have my book, you can search for "system-func" to see various examples of how to use ACL with FOSI. If you don't have my book, it is available at http://fosiexpert.com/Practical-FOSI.html.

    Good luck!

    Hi Caroline,

    Sorry, I don't have a revdate function handy to share. You need oid_current_tag() to provide the oid for oid_attr.

    The FOSI code should work. However, you do not need the specval to test if the attribute has a value. If it doesn't, the fillval is automatically ignored. The formatting engine handles error checking like that so you don't have to 🙂

    Good luck!

    Thanks, Suzanne, I didn't know about the error checking.

    But what I wanted to know is if there is a way to pass an attribute as a parameter to an ACL function. I haven't found any examples doing that. I had to create a second function to pass the revdate attribute to the format_date function:

    <fillval attname="myfuncs:get_revdate" attloc="system-func" fillcat="savetext" fillchar="conrule">

    ...

    function get_revdate(window,oid) {

    local v; 

    v = format_date(window,oid, "revdate")

    return v

    }

    I didn't like hardcoding revdate in the ACL. I wanted to do something like this:

    <fillval attname="myfuncs::format_date('revdate')" attloc="system-func" fillcat="savetext" fillchar="conrule">

    function format_date(window, oid, attr) {

    ...

    local date=oid_attr(oid, attr);

    ...
