[RESOLVED] counter changes on browser refresh

[saco721]

Hi!,

I am having a strange problem with my code. Basically the counter $_SESSION['total_number'] decrements each time the browser refresh button is pressed, even if the 'Click to download' link has not been pressed. How do I stop this from happening?. The counter should only change if 'Click to download' is pressed and then the browser refresh button. Here is the code:

<?php
error_reporting(E_ALL);
session_start();

if( !isset($SESSION['total_number']) ) {
$SESSION['total_number'] = 3; // store session data
}
$test1 = "myfile.pdf";
$test2 = "John Doe";
if ( $test2 ) {
echo ("$test2");

echo ("<td><font face = \"Verdana\" size = \"2\"><a href=\"samofile.php?arg1=$test1\">Click to download.[/url]</font></td>");
echo "Downloads left = ". $SESSION['total_number'];//retrieve data
$SESSION['total_number']--;
} else {
echo ("$test2");
echo ("downloads complete");
}

?>

Thanks for your time!

any ideas?

Hi bpat1434,

here's the code as requested.

thanks!

<?php
$strFilePath = $GET['arg1'];
$SESSION['total_number']--;
$strFileSize = filesize($strFilePath);
$strFileName = basename($strFilePath);

header("Content-Type: $ContentType");
header("Content-Length: $strFileSize");
header("Content-Disposition:attachment; filename=$strFileName");

$fp = fopen($strFileName, 'rb');
fpassthru($fp);
fclose($fp);
?>

You need to call session_start() at the top of any file where you want to use $_SESSION variables
