When I run the following .hasMore() / .getNext() loop, it will end up
skipping every other record. If I specify to delete 1,2,3,4 as the
example shows, it will only delete 1 & 3. This makes me believe that I'm
somehow triggering .getNext() twice during each loop. Is there a better
way to access the record attributes returned from Iterator.getNext()
without advancing to the next record until I loop around again?
Sample Code:
<cfparam name="FORM.photosToDelete" default="1,2,3,4"> <!--- Delete
photos 1 through 4 --->
<cfset photos = article.getPhotoIterator()>
<!--- Assume that photo records 1 through 4 are the only ones associated
with this article record through the Iterator and are returned with full
attributes --->
<cfloop condition="photos.hasMore() IS TRUE">
<cfset thisPhoto = photos.getNext()>
<cfif listContains(FORM.photosToDelete, thisPhoto.getID())>
<cffile action="delete"
file="#thisPhoto.getPath()#">
<cffile action="delete"
file="#thisPhoto.getThumbnailPath()#">
<cfset thisPhoto.delete()>
</cfif>
</cfloop>
I've read through the Iterator source code, and the Iterator example at
(http://www.doughughes.net/index.cfm?event=viewEntry&entryId=199), but
I'm still learning. Please let me know if you see my error or have a
better solution.
Thank for any suggestions,
Dan
