[RESOLVED] does $_SESSION['name'. var] work??

DBHostS

can i have a session like this:

$_SESSION['download'.$id]; ?

or if i have it in a loop and use it like this:

$_SESSION['download'.id[0]]; ?

i am trying to search a directory and then search the file names in that directory to see if the filenames has the id in it and if it does set the session $_SESSION['download'.$id]; to show the download link for that file.

i thought i had it working. i can see a session like this $SESSION['download'.$id]; and then echo the value of it by using echo $SESSION['download'.$id];

maybe its my if statement. i just want to make sure i can use the SESSION variable like this.

Thanks in advance.

Certainly! You might try checking for the session value with

isset($_SESSION['download'.$id])

In addition,

print_r($_SESSION)

can be helpful when you are trying to see what your sessions variables contain.

If I may suggest, you might make things easier on you by storing the ids in a session array:

//initialize
if (!is_array($_SESSION['download']) {
$_SESSION['download'] = array();
}

//push $id to array
$_SESSION['download'][] = $id;

//use in_array() to test for id
if ( in_array($id,  $_SESSION['download']) ) {
   // do stuff...
}

//or better make the id the associate key to avoid duplicate ids
$_SESSION['download'][$id] = 1;
//or increment associative array if you want to keep track of duplicates.
 $_SESSION['download'][$id]++;

//use array_key_exists() to test for id
if ( array_key_exists($id,  $_SESSION['download']) ) {
   // do stuff...
}

//you can also use isset to test with an associative array.
if ( isset($_SESSION['download'][$id]) ) {
   // do stuff...
}

thanks for the reply.
i will try that out thanks.

but i have been testing this code i have .

i notice i set the sessions fine but in my if else statement that is nested into a foreach statement the else statement is being executed and thats why it wasnt working. i commented the else statement out and it works fine. but when i delete the file from the directory the session will is still set.

Heres my code. both the if and the else runs making all the sessions not set at all.

in session.php:
/**
 * Check the download link
 *
**/
function checkDownloadLink($resumeid, $user) {

//get the filename from the directory.	
$files = $this->getFiles("resumes/docs");

	foreach ($files as $file){

	      if($user == $this->get_usersname($file[name]) && $resumeid == $this->get_usersresumeid($file[name])){
                                       //set the session to show the download link
					$_SESSION['download'.$resumeid] = 1;
                                       //testing purposes
					echo $_SESSION['download'.$resumeid];
		}			
	//unset if the user or id isnt in the filename.	
	//else{
	//				unset($_SESSION['download'.$resumeid]);
	//	}
       }

}

i have more code if you need to see the other functions but it works fine i am just having a problem where i am unsetting the session if the if statement didnt go through.

and the echo statement works. meaning when there is one file it only echos 1 one time. if there are two files containg the user and id the echo spits out two 1's. even when i have the else statement not commented.

Thanks again.

ahhh i fixed it im pretty sure.

in if(isset($_SESSION['download'.$resumeid])) statement for the sessions right at the end i unset it there fixing all the problems for this.

thanks for your input.
