list attachment on wordpress - wordpress

Question

i have this code:
<?php
$valid_ext = array("pdf", "doc");
$args = array(
'post_type' => 'attachment',
'post_mime_type' => 'application/pdf',
'numberposts' => 40,
'post_status' => null,
'post_parent' => null, // any parent
);
$attachments = get_posts($args);
if ($attachments) {
foreach ($attachments as $post) {
$ext = getFileExt(wp_get_attachment_url($post_id, false));
if(in_array($ext, $valid_ext)) {
?>
<li>
<div class="entry-date">
<abbr class="published" title="<?php the_time('Y-m-d\TH:i:sO')?>">
<?php unset($previousday); printf( __( '%1$s – %2$s', 'sandbox' ), the_date( '', '', '', false ), get_the_time() )?>
</abbr>
</div>
<div id="post-<?php the_ID()?>" class="<?php sandbox_post_class()?> " style="padding:0; margin:0;">
<p style="font-size:11px; text-transform:uppercase;">
<?php setup_postdata($post);the_attachment_link($post_id, true);?>
</p>
</div>
</li>
<?php
}
}
}
?>
it gives me as output a date and a link with the document name.
<li>
<div class="entry-date">
<abbr title="2011-06-15T17:30:29+0200" class="published">
15 giugno 2011 – 17:30
</abbr>
</div>
<div style="padding:0; margin:0;" class="hentry p11 attachment inherit author-daniela-santanch category-senza-categoria untagged y2011 m06 d15 h17 " id="post-2158">
<p style="font-size:11px; text-transform:uppercase;">
<a title="la_stampa_07_06_2011" href="http://www.mpli.it/wp/wp-content/uploads/2011/06/la_stampa_07_06_2011.pdf">la_stampa_07_06_2011</a> </p>
</div>
i'd like to get the post title linking directly to the document.
any help?

Try this:
<?php
$args = array( 'post_type' => 'attachment', 'numberposts' => -1, 'post_status' => null, 'post_parent' => null );
$attachments = get_posts( $args );
if ($attachments) {
foreach ( $attachments as $post ) {
setup_postdata($post);
the_title();
the_attachment_link($post->ID, false);
the_excerpt();
}
}
?>
