Help needed displaying images in file

[Guest]

I have a directory of photographs that I wish to display one in a main folder and one in a folder called thumbs. Now there will always be a thumbs counterpart to the original image so for example I would like to display it:

<a href="123.jpg"><img src="thumbs/123.jpg"><br />123.jpg</a>

How can I have cold fusion cycle through files in a directory and do this for me?

<cfdirectory action="LIST" directory="#getDirectoryFromPath(expandPath('*.*'))#" filter="*.jpg" name="dir">
<cfloop query="dir">
<cfif dir.type is "file">
<!--- <div> --->
<cfoutput><a href="#dir.name#"><img src="thumbs/#dir.name#"><br />#dir.name#</a></cfoutput>
<!--- </div> --->
</cfif>
</cfloop>

to even further simplify the code:

<cfdirectory
action="LIST"
listinfo="NAME"
directory="#expandPath('relative_path_to_images_dir_here')#"
filter="*.jpg"
name="qDir"
type="FILE">

<cfoutput query="qDir">
<!--- <div> --->
<a href="#qDir.name#"><img src="thumbs/#qDir.name#"><br
/>#qDir.name#</a>
<!--- </div> --->
</cfoutput>

A bit difficult to say.

<cfoutput query="qDir"><cfoutput>
I agree that yours is in general simpler than
<cfloop query="qDir"><cfoutput></cfoutput></cfloop>.
However, the comparison is not so obvious when there is text in the loop. I have indicated that with a div tag. There could be much more text to which it would be unnecessary to apply the cfoutput tag.

directory="#expandPath('relative_path_to_images_dir_here')#"
The hard-coded path limits the use of this code. You will have to rewrite it in certain situations.

type="FILE"
Coldfusion 8 introduced that attribute. So, for older versions, it is a complication, not a simplification.

In any case, PopcornCoder now has more to play with. Which can only be a good thing.

iirc, type="file" existed in cfmx7, but was not documented.

same for listinfo="name", which significantly reduces the amount of data
returned by <cfdirectory> query.

also, your directory="#getDirectoryFromPath(expandPath('*.*'))#" will
query the directory the calling page is in, which is likely NOT to be
the directory the images are stored in.

and we both have omitted the recurse="no" attribute, which is important,
especially if the thumbs directory is inside the main images directory...

Really? Strange. The documentation says, "ColdFusion 8: Added the listinfo and type attributes."

also, your directory="#getDirectoryFromPath(expandPath('*.*'))#"
will query the directory the calling page is in, which is likely NOT
to be the directory the images are stored in.
The snippet href="123.jpg" tells me the calling page will quite likely be in the same directory as the images.

we both have omitted the recurse="no" attribute, which is
important, especially if the thumbs directory is inside the main
images directory...
I don't think we really have. When you omit it Coldfusion uses the default, which happens to be recurse="no". Also, you don't have to take the thumbnails into account when setting up cfdirectory. You get each thumbnail's path from the corresponding image.
