I am trying to write a complex custom tag that does paged output of a query:
<CF_OutputPage query="myquery" startrow=1 maxrows=10>
...stuff with #myquery.column# ...
</CF_OutputPage>
<!--- returns: outputpage.numpages, outputpage.thispage, outputpage.prevstart,
outputpage.nextstart --->
The easiest way is the following:
If ExecutionMode is 'start', calculate number of pages, prevstart, nextstart, etc.
return those in caller.outputpage.#var#, and somehow "spit out" a CFOUTPUT:
<CFOUTPUT QUERY="#attributes.query#" STARTROW="#attributes.startrow#"
MAXROWS="#attributes.maxrows#">
If ExecutionMode is 'end', just "spit out" the close CFOUTPUT:
</CFOUTPUT>
But this doesn't work. No matter how I try to "spit out" <CFOUTPUT> I either get
nesting errors because I am opening a CFOUTPUT in the module without closing it, OR I
get the actual text "<CFOUTPUT>" in my browser source (Explorer doesn't do a whole lot
when it sees <CFOUTPUT> :-) )
I thought I was *really* clever when I tried this:
ThisTag.GeneratedContent = "<cfoutput query=""#attributes.query#""
startrow=#attributes.startrow# maxrows=#attributes.maxrows#>" &
ThisTag.GeneratedContent & "</cfoutput>";
But I still just got this text in my browser source :-(
Is there any way to "spit out" CFML like a macro for the calling tag to use?
The only other way I can think of is *nasty*. I would have to set up local variables
for each column and manually do the subtitutions by evaluating the GeneratedContent,
then use <CFEXIT METHOD="loop"> to loop through each row of the result set. oooph!
