Well, even though there's some issue of the best way to pull this off, I am
having another problem. I am trying to create a custom tag that will out put
user data into x number of columns with the attributes being QueryName and
NumberOfColumns. My problem now is that I want to be able to mix plain text
or html with variables. I've gotten it to do one or the other, if I use
#evaluate(localcontent)# in the code below, I can output variables from the
query that were passed, if I don't use evaluate, I can get text, but the
variables show up as #variable#. Anyone know a way around this?
<!--- da code --->
<cfswitch expression="#ThisTag.ExecutionMode#">
<cfcase value="Start">
<cfif NOT ThisTag.HasEndTag>
<cfabort showerror="This tag needs an end tag">
</cfif>
<cfif NOT IsDefined("Attributes.QueryName")>
<cfabort showerror="The attribute QUERYNAME is required to
run this tag">
</cfif>
<cfparam name="Attributes.NumberOfColumns" default="3">
</cfcase>
<cfcase value="End">
<cfset LocalContent=ThisTag.GeneratedContent>
<table border="0" cellpadding="2" cellpsacing="2" width="100%">
<cfoutput query="#LocalQuery#">
<cfif currentrow mod attributes.NumberOfColumns is 1>
<tr>
</cfif>
<td align="right"> #LocalContent# </td>
<cfif currentrow mod attributes.NumberOfColumns is 0>
</tr>
</cfif>
</cfoutput>
<cfif LocalQuery.recordcount mod NumberOfColumns is not 0>
<cfset variables.ColsLeft = attributes.NumberOfColumns -
(LocalQuery.recordcount mod attributes.NumberOfColumns)>
<cfloop from = "1" to = "#variables.ColsLeft#" index = "i">
<td> </td>
</cfloop>
</tr>
</cfif>
</table>
</cfcase>
</cfswitch>

Some people (not necessarily me) believe doing this is better:
<cf_mytag theQuery="#myQuery#"/>
i.e. passing the query by value and hence avoiding breaking any kind of
encapsulation.
Inside the tag you refer to the query in the normal way e.g.
<cfset localQuery = attributes.theQuery>
or just:
<cfloop query="attributes.theQuery">
...
</cfloop>
However, if you follow the syntax of native ColdFusion tags then the
analogous approach is to do what you have opted to do. E.g.
<cf_mytag theQuery="myQuery"/>
Inside the tag:
<cfset localQuery = caller[attributes.theQuery]/>

Thanks everyone, I was passing the queryname in as an attribute and
<cfset
_localQuery = Evaluate("Caller." + Attributes.query) /> was just what I
needed. I had to change the + to & for concatenation though.
Thanks

If myquery is the query on your page then in your custom tag
<cfset _localQuery = Caller.myquery />
Better is to pass the query in the tag
<cf_mytag query="myquery" />
and in the tag
<cfset _localQuery = Evaluate("Caller." + Attributes.query) />

Is there a way to access an existing query recordset from a custom tag
called on the page? So if I have a query in a page, and I call a custom
tag,
can i use the query data through come sort of caller scope object? I
can't
seem to make it work.
Thanks
