I wonder if some nice person could spot what I'm doing wrong here? This script lists the newsletter issues in a directory and allows you to press on a link which should post that specific issue number to the next page. Trouble is, the same number is posted whichever link is pressed.

PHP Code:

$dir = opendir('newsletters/');

while (false !== ($read = readdir($dir))) {
if (substr($read,0,5)=='Issue') {
$issue=substr($read,5,2);
echo '<form name="form' . $issue . '" method="POST" action="newpage.php">';
echo '<input name="issue" type="hidden" value="' . $issue . '" /><a href="javascript: submitform()">Issue ' . $issue . '</a></form>
<SCRIPT language="JavaScript">
function submitform()
{
  document.form' . $issue . '.submit();
}
</SCRIPT>';
}
}
closedir($dir);

Examine the HTML page source that is generated by your script to find the problem, or post it here.

Thanks so much for replying. The page posts to another page (calling it "newpage.php" in the script is a bit confusing - it's just another page). WIthout boring you with all the script, basically I'm trying to catch the incoming post with:

PHP Code:

$issue = $_POST['issue']; 


then I use it in the rest of the script, such as

PHP Code:

$query = "SELECT * FROM newslettertable WHERE issue='" . $issue . "' ORDER BY id"; 


etc.

You're creating a lot of javascript functions with the same name: submitform. That's your problem.

Also, you're over-complicating things so badly it's amazing.

PHP Code:

$dir = opendir('newsletters/');

while (false !== ($read = readdir($dir))) {
    if (strtolower(substr($read, 0, 5)) == 'issue') { //case insensitive check
        $issue = substr($read, 5, 2);
        echo '<a href="newpage.php?issue=' . $issue . '">Issue ' . $issue . '</a><br>';
    }
}
closedir($dir); 


Use that and on newpage.php replace $_POST['issue'] with $_GET['issue']

Well, yes - I'd convinced myself I had to POST the information and wanted a text link instead of a SUBMIT button. GET is better, you're right. I want to list all items in the directory beginning with the word Issue (cap I) - but I'm now not seeing anything in the list at all....
