[RESOLVED] directory not recognizing session id

jhlew

I have a calendar on my website that uses PHP to make a directory on my server, then when the user inputs an event, a txt file is created for that event. I can place a txt file in the directory after it is automatically created, and I can manually change the directory in the PHP to what I know is the member id folder and it prints on webpage. But when I use the $id variable, (to allow each member to see their own events in the own created directory) it somehow loses the connection or something.

let me know if anyone has any suggestions. I am still new to sessions, but I know the session is producing an id because when I print $id by itself, I see the correct id that corresponds to the folder.

What "$id" variable? You're going to have to show us some code if you expect us to be able to answer questions about it. 😉

youre right. sorry.

the $id variable is the session id ... which corresponds to the member id in the database.
when I try this code below, I get nothing.

if ($handle = opendir('data/$id')) {
     	while (false !== ($file = readdir($handle))) {
     		if (preg_match("/$sieve/", "$file")) {
     			$data = file_get_contents('data/$id/'.$file);
     			list($title, $desc, $time, $class) = explode("|-NN-|", $data);
    			echo '<div class="' . $class . '"><span>' . $title . '</span>';
     			echo $desc;
     			echo '<span>' . $time . '</span></div>';
     		}
     	}
     	closedir($handle);
     }

But for example, if the member id is "7".

and I put this code in ... it works.

if ($handle = opendir('data/7')) {
     	while (false !== ($file = readdir($handle))) {
     		if (preg_match("/$sieve/", "$file")) {
     			$data = file_get_contents('data/7/'.$file);
     			list($title, $desc, $time, $class) = explode("|-NN-|", $data);
    			echo '<div class="' . $class . '"><span>' . $title . '</span>';
     			echo $desc;
     			echo '<span>' . $time . '</span></div>';
     		}
     	}
     	closedir($handle);
     }

Your problem has to do with the way [man]string[/man]s work in PHP, more specifically variable interpolation. Simple example:

$id = 123;

echo 'The id is: $id'; //output: The id is: $id
echo "The id is: $id"; //output: The id is: 123
