You mean PHP outputs
but Flash outputs
&filetypes=Text Files (*.TXT;*.RTF; )&fileextension=*.txt; *.rtf
Also I think you might want to consider using a different deliminator than ; I like the | myself. That might help here and do you really need an * in front of them all?
&filetypes=Authorised files (*.JPG;*.JPEG;*.JPE;*.GIF;*.PNG;*.tiff;*.tif;*.zip;*.rar;*.doc;*.pdf;*.xls;*.sit;*.ppt;*.csv;*.txt;*.rtf;*.xdoc; )&fileextension=*.jpg; *.jpeg; *.jpe; *.gif; *.png; *.tif; *.tiff; *.zip; *.rar; *.doc; *.pdf; *.xls; *.ace; *.sit; *.ppt; *.csv; *.txt;*.rtf;
I would think that this type of a string would be easier to process later in Flash. You could always pop the first entry as the title and then each of the rest as file extensions. I can't seem to find it, but I know there are a few characters that might cause some issues when used (of course & because it notes a new variable, so it must be urlencoded if you use it in your text).
