I modified some code I made to do something similar:
<?php
$pix = opendir( "videos" );
while (($item = readdir ($videos)) !== false){
if ($item != "." && $item != "..") {
echo "<a href=\"pics/$item\">";
$count++;
echo "<br />";
}}}
closedir ($videos);
?>
I haven’t tested this, but it should work… You’ll just have to create a separate page(not a wordpress one) to put this on, and a “videos” directory to put all the videos on.
I would back up all your files and your database, then try.
I don’t know if this would work for you, but:
<?php
echo "Please enter your password<br />";
echo "<form method="POST" action="accpass.php">";
echo "<input type="textbox" name="password123">";
echo "<input type="submit">";
?>
Then on accpass.php have it see if $password123 == yourpassword, and if so, give them the link. I’m not sure if that helps, but it’s an idea.
