ColdFusion 8: Added the listinfo and type attributes.
ColdFusion MX 7: Added the recurse attribute (named recursive in Alpha 1) and directory result-set column.
ColdFusion MX:
Attribute |
Req/Opt |
Default |
Description |
---|---|---|---|
directory |
Required |
|
Absolute pathname of directory against which to perform action. You can use an IP address, as in the following example: <cfdirectory directory="//12.3.123.123/c_drive/" name="dirQuery" action="LIST"> |
action |
Optional |
list |
|
filter |
Optional if action = "list" |
|
File extension filter applied to returned names, for example, *.cfm. One filter can be applied. |
listinfo |
Optional |
all |
|
mode |
Optional |
|
Used with action = "create". Permissions. Applies only to UNIX and Linux. Octal values of chmod command. Assigned to owner, group, and other, respectively, for example:
|
name |
Required if action = "list" |
|
Name for output record set. |
newDirectory |
Required if action = "rename" |
|
New name for directory. |
recurse |
Optional |
no |
Whether ColdFusion performs the action on subdirectories:
Valid for action="list" and action="delete". |
sort |
Optional; used if action = "list" |
ASC |
Query columns by which to sort a directory listing. Delimited list of columns from query output. To qualify a column, use one of the following values:
For example: sort = "directory ASC, size DESC, datelastmodified" |
type |
Optional |
all |
|
If you put ColdFusion applications on a server that is used by multiple customers, you must consider the security of files and directories that could be uploaded or otherwise manipulated with this tag by unauthorized users. For more information about securing ColdFusion tags, see Configuring and Administering ColdFusion.
If action = "list", cfdirectory returns the following result columns, which you can reference in a cfoutput tag:
Use the following result columns in standard CFML expressions, preceding the result column name with the query name:
#mydirectory.name# #mydirectory.directory# #mydirectory.size# #mydirectory.type# #mydirectory.dateLastModified# #mydirectory.attributes# #mydirectory.mode#
The filter attribute specifies a pattern of one or more characters. All names that match that pattern are included in the list. On Windows systems, pattern matching ignores text case, on UNIX and Linux, pattern matches are case-sensitive.
The following two characters have special meaning in the pattern and are called metacharacters:
The following table shows examples of patterns and filenames that they match:
Pattern |
Matches |
---|---|
foo.* |
Any file called foo with any extension; for example, foo.html, foo.cfm, and foo.xml. |
*.html |
All files with the suffix .html, but not files with the suffix .htm. |
?? |
All files with two-character names. |
