This is the code for the category drop-down:
<form action="<?php echo $PHP_SELF ?>" method="get">
<label for="cat"><?php _e('Subjects:'); ?></label><br />
<?php dropdown_cats(1,'All Subjects','name','asc',0,1,1); ?>
<input type="submit" name="submit" value="Go!" />
</form>
This is the code for the monthly archive dropdown:
<form action="/journal/redirect.php" method="post">
<label for="arch"><?php _e('Monthly Archives:'); ?></label><br />
<select id="arch" name="arch">
<?php get_archives('','','option', 1); ?>
</select>
<input type="submit" name="submit" value="Go!" />
</form>
And this is whats in the redirect.php referenced above:
<?php
$URL=$_POST['arch'];
header ("Location: $URL");
?>
Isn’t that lovely?
