In some circumstances, the folder won't be created. In fact this is one of the fixes that will be in the next update of Digital File Pro V1. Sorry I can't give any dates as testing is still underway.
However, if you open up this file:
WA_DigitalFilePro/HelperPHP.php
And go down to the bottom and look for the rootRelativeToFullFileURLfunction and replace it with the following:
function rootRelativeToFullFileURL($folderPath){
if(strpos($folderPath, "/") === 0){
$scriptName = $_SERVER['SCRIPT_NAME'];
$currentFilePath = realpath(basename($scriptName));
$replaceBackSlash = preg_replace('/\\\/', '/', $currentFilePath);
$scriptNameRegEx = "/".preg_replace("/\\//", "\\/", $scriptName)."$/";
$folderPath = preg_replace($scriptNameRegEx,"", $replaceBackSlash).$folderPath;
}
else{
$separator= WA_DFP_GetFileSeparator();
// Use correct separator
$origFolderPath = preg_replace('/\\\|\\//', $separator, $folderPath);
$folderPath = realpath('./').$separator.$origFolderPath;
// drop any trailing slash, as realpath doesn't return it either.
$folderPath = preg_replace("/\\".$separator."$/", "", $folderPath);
}
return $folderPath;
}
That should help make sure the folder is getting created. If not, then please do log a support incident as your specific setting may lead to a different issue.
