handy if you want to use CFINCLUDEs using absolute paths instead of
relative paths. It gives the application more directory path
independence, allowing you to relocate the directory that the application
resides in without changing any code.
Example:
<cfinclude template="#PathTo('/include/header.cfm')#">
<cfscript>
/*
* Return a relative path from the current page to an
* absolute URL on the same site.
*/
function PathTo(t) {
var fa = ListToArray(cgi.script_name, '/\');
var ta = ListToArray(t, '/\');
var flen = ArrayLen(fa);
var tlen = ArrayLen(ta);
var rpath = '';
var i = 0;
var j = 0;
// Find common branch point in paths
for (i=1; i lte Min(flen, tlen); i=i+1)
if (fa[i] is not ta[i]) break;
// Path back to branch
rpath = RepeatString('../', flen - i);
// Append remainder of path to target
for (j=i; j lte tlen; j=j+1)
rpath = rpath & IIf(j neq i, DE('/'), DE('')) & ta[j];
return rpath;
}
</cfscript>
