Hi, David, glad you're sticking with it.
I don't understand what you're trying to do here, though:
> if(!is_dir($dirBase."/".$get_the_album) || strtr($get_the_album, ".") !=NULL
> || strtr($get_the_album, "\\") !=NULL){
> echo "Album does not exist.";

PHP function strtr takes 2 or 3 arguments, but if only supplying a
simple string for argument 2, you *must* supply a string for argument
3 as well.
When I try this:
$ php -r '$s = strtr("a string","."); var_dump($s);'
This is the result:
PHP Warning: strtr(): The second argument is not an array in Command
line code on line 1
PHP Stack trace:
PHP 1. {main}() Command line code:0
PHP 2. strtr() Command line code:1
bool(false)
which indicates the strtr function call failed.
What is it you want to do there? Are to trying to see if
$get_the_album contains a "." or a backslash? If so, you will want to
use some sort of search or match facility, not the character
substitution function of strtr. If so, something like this will work
instead:
if (
! is_dir($dirBase."/".$get_the_album) // this is not a directory
|| ! strpos($get_the_album, '.') // directory name does
not contain a period
|| ! strpos($get_the_album, '\') // directory name does
not contain a backslash
)
{
echo "Album does not exist.";
}
If that isn't what you want to do, could you provide a simple sentence
(not code) of what you want to do there?
