Sending file list to bash script

[raparperi]

I have the following script (dead2m3u.sh) which i call from deadbeef shell command like this
dead2m3u.sh %F. The problem is that if i select two or more files from deadbeef it asks dialogs as many times as there is selected files. Same script run from Thunar shell command with same call asks dialogs only once as it should. What can be done to make it work same in deadbeef?

#!/bin/bash
lista="uusi-";
tarkenne=".m3u";
polku="/home/jj/m3u/soittolistat/";

ok=true;
cur=0;
for file in "$@";
do
if [ "$cur" = 0 ]; then
lista=$(kdialog --title "Input dialog" --inputbox "Give .m3u filename without extension" "$lista");
kdialog --yesno "Save chosen into list $lista$tarkenne ?";
if [ "$?" = 0 ]; then
ok=true;
else
ok=false;
fi
fi

if [ "$ok" = true ]; then
	echo "$file" >> "$polku$lista$tarkenne";	
fi

let cur++;

done
