cfloop within a cfif tag

[cstrodtb]

Is it possible to nest a cfloop inside a cfif tag?

I'm outputting a directory listing of files, but only want to allow certain file types. I can do something such as:

<cfif dir.name CONTAINS ".cfm" OR dir.name CONTAINS ".html"...>

However, it would be much nicer if I could just store a list of file extensions in a variable and have a cfif statement that loops through them. That would make it much easier to add or remove extensions from the list of allowed file types. Is this doable? If not, is there something similar I could do?

Hi,

You don't even need a loop, you can use listfind().

Here's an example for what I usually use.

cheers,
fober



<cfset application.upload_allow= "txt,doc,xls,ppt,mdb,htm,html,gif,tif,jpg,jpeg,png,zip,pdf,rtf">


<cfif isdefined("file_upload") IS TRUE>
<cfif evaluate("len(file_upload)")>
<cffile action="UPLOAD"
filefield="file_upload"
destination="#application.app_content_folder#"
nameconflict="MAKEUNIQUE">
<cfif listfind(application.upload_allow, cffile.clientFileExt) Is 0>
...delete the file and error message
</cfif>
</cfif>
</cfif>

you know that <cfdirectory> tag has a FILTER attribute, where you can
define multiple filters for the files you want returned by <cfdirectory>
query?
like this:
<cfdiretory name="mydirquery" directory="#expandpath('.')#"
filter="*.cfm|*.htm*">

he above will return all .cfm, .htm and .html files from current
directory (the one the calling page is in).

Neither of those are quite doing what I want.

I don't want to not display certain files, so using cfdirectory isn't going to cut it.

It seems that listFind can't find a string from the list WITHIN a string, so if I have a list of "cfm,cfc,html,js" and use listFind against a filename such as "hello.cfm", it returns false since "hello.cfm" doesn't EQUAL one of the list elements.

I could create a variable that only pulls the last three characters of the filename (which is effectively the extension), but this isn't quite what I want, since my list of conditions includes more than just file extensions (it also includes specific files, such as index.cfm and Application.cfm).

You can nest tags like this:
<cftag1>
<cftag2>
</cftag2>
</cftag1>

but not like this
<cftag1 <cftag2></cftag2>></cftag1>

For your specific problem, one of the following cold fusion functions might be useful
find
findnocase
refind
refindnocase
contains

Usage is described in the cfml reference manual. If you don't have one, the internet does.

<cfset myfileextlist = "cfm,cfc,htm,html">
<cfset myfilename = "hello.cfm">
<cfoutput>#listfindnocase(myfileextlist, listlast(myfilename,
"."))#</cfoutput>
