ColdFusion Need help with download file/s function

The code below does the following:
For each record checked it will look inside a folder (each record has a folder) and download the file. Users can click one or many records to download. The download to a zip folder function runs after this code and is not shown.

How can I add the functionality of downloading all files (in each folder/record) instead of just one file? If I place 2 PDF's in one of these folders, only one will be downloaded.
Do I need to create a loop within a loop?


<CFLOOP INDEX=j FROM=1 TO=#ArrayLen(myarray)#>
	<CFSET ChkDir="\\DSS1\Shared_Data\325\DDA\www\tasks\#myarray[j]#\NUL">
	<CFIF #FileExists(chkdir)# eq 0>  <!--- Set to 0 because this function isn't working -=DOES A FOLDER EXIST FOR THIS DOCUMENT?  --->
		<CFDIRECTORY DIRECTORY="\\DSS1\Shared_Data\325\DDA\www\tasks\#myarray[j]#" NAME="tiidquery" filter="*.pdf" SORT="name ASC">
		<CFIF #TIIDQUERY.RecordCount# GT 0>  <!---  ARE THERE ANY .PDF FILES IN THE FOLDER --->
			<cfset downloadable="yes">
			<CFQUERY NAME="QUERY" DATASOURCE="Web_dd">
			SELECT DISTINCT * FROM DD_TASKINFO WHERE TI_ID=#myarray[j]#
			</CFQUERY>
			<CFSET TIIDNAME=#SpanExcluding(tiidquery.name,".")#>
			<CFSET JMX_DocNumber=#TRIM(tiidname)#>
			<CFSET JMX_DocumentSize="A">
			<CFOUTPUT QUERY="QUERY">
				<CFSET JMX_DocRevision=#Trim(ti_rev)#>
				<CFSET JMX_DocumentTitle=Left("#Trim(ti_brief)#",40)>
			</CFOUTPUT>
			<CFLOOP QUERY=TIIDQUERY>
				
                        <CFIF find(".PDF","#UCASE(NAME)#") NEQ 0>
	<CFDIRECTORY ACTION="create" DIRECTORY="c:\dwgbin\#DLname#\#tiidname#">
<CFFILE ACTION="Copy" SOURCE="\\DSS1\Shared_Data\325\DDA\www\tasks\#myarray[j]#\#name#" DESTINATION="c:\dwgbin\#DLname#\#tiidname#\">

Basic example:

You want to zip the following 3 files into 1 zip file.
<cfset files="d:\files\images\img1.png,d:\files\docs\doc1.docx,d:\files\pdfs\pdf1.pdf">

Where to save your zip file
<cfset filename="d:\files\zips\myzipfile.zip">

<cfset overwrite=1>
<cfloop list="#variables.files#" index="ii">

      <cfzip
            source="#ii#"  
            action="zip"
            overwrite="#variables.overwrite#"
            file="#variables.filename#">

<cfset overwrite=0>
</cfloop>
You'll now have 1 zip file that contains the 3 files from the variable files.

So the concept is to do your preliminary work grabbing your filepath + filename for all files you want to zip.
Then run code similar to this and that's pretty much it.

good luck ...

AFAIK, you can't. HTTP requests don't work that way.  They're designed to send a single file/filetype (normally). I read somewhere it might be possible by exploiting multi-part headers, but even if did work... browser support would be spotty at best. Your best bet is to stick w/a single zip file. That's the standard solution to the single file limitation.

I am looking for a singe zipped file. The current CF code just extracts 1 file in each folder.

The existing operation:
The user checks the boxes of desired records - CF looks inside each folder and extracts the file (1 - PDF) and zips them up, then a download button is displayed.

Works great.

Modified desired operation:
The user checks the boxes of desired records - CF looks inside each folder and extracts the file/s (1 or more - PDF's) and zips them up, then a download button is displayed.
