one, I have made a CFC that traverses through the directory structure and
returns a query with the whole directory structure underneath the parent it
was given.
Then I have made a CFC that is to work with this query and visually recreate
the directory structure with HTML <ul> and <li> I am almost there, but there
is a problem somewhere, which I can't pinpoint. It recreates the directory
structure fine as long as the structure is going up once it goes down there
is a problem somewhere.
Code to run for testing (if anyone is interested in getting this working)
<cfscript>
directory = createObject("component",
"/openAMS_development/frameWork/component/directory");
tree = createObject("component",
"/openAMS_development/frameWork/component/tree");
qDirectory = directory.traverse(
'D:\Inetpub\wwwroot\internet\development\openams.com\index\' );
</cfscript>
<cfquery name="q" dbtype="query">
SELECT *
FROM qDirectory
WHERE [type] = 'Dir'
</cfquery>
<cfset myTree = tree.html(q, "nothingyet", "nothingyet", "nothingyet")>
