Question

I have a function that accepts a file path. Users can pass in either an absolute or relative path to a file. If a relative path is provided, the ExpandPath function can convert it to an absolute path like so:

<cfset filepath = ExpandPath("data/test.txt") >

.. and it returns:

C:\www\example\data\test

But if user provides an absolute path like:

<cfset filepath = ExpandPath("C:\www\example\data\test") >

.. it returns:

C:\www\example\C:\www\example\data\test

How may I solve this problem?

Answer 1

You could test the string and see if it starts with C:\ for windows or \\ for unix, and use that as an if?
This could be your windows check:

<cfif reFindNoCase("[a-zA-Z]:\\",myFileLocation)>
   <!--- Is a absolute path --->
<cfelse>
   <!--- Is not an absolute path --->
</cfif>
