Creates an absolute, platform-appropriate path that is equivalent to the value of relative_path
, appended to the base path. This function (despite its name) can accept an absolute or relative path in the relative_path
attribute
The base path is the currently executing page's directory path. It is stored in pageContext.getServletContext().
A string. If the relative path contains a trailing forward slash or backward slash, the return value contains the same trailing character.
ExpandPath(relative_path)
FileExists,
GetCurrentTemplatePath,
GetFileFromPath
New in ColdFusion MX: this function (despite its name) can accept an absolute or relative path in the relative_path
attribute. To resolve a path, this function uses virtual mappings that are defined in the ColdFusion Administrator. This function does not reliably use virtual mappings that are defined in IIS, Apache, or other Web servers.
If the parameter or the returned path is invalid, the function throws an error.
These examples show the valid constructions of relative_path:
ExpandPath( "*.*")
ExpandPath( "/")
ExpandPath( "\")
ExpandPath( "/mycfpage.cfm")
ExpandPath( "mycfpage.cfm")
ExpandPath( "myDir/mycfpage.cfm")
ExpandPath( "/myDir/mycfpage.cfm")
ExpandPath( "../../mycfpage.cfm")
