.........................^^^^^^^^^^^^
What is that?
a) a variable; then you must write $row[$vir_dir_name]
b) a string; then you should write $row["vir_dir_name"]
You should know, that variables from outside a function are not visible
inside a function:
$name = "Moritz";
function print()
{
echo $name;
}
will produce *nothing*;
Instead you must write it like:
$name = "Moritz";
function print()
{
global $name;
echo $name;
}
(normally a function should not access a variable from outside, but
sometimes there is no other way...)
Hope it helps,
Moritz.
