The attachement piece is great but a way to view the document properly is need it, I use it to put designs and notes related to the project in the quote for faster reference.
I added a hyperlink that will display the link to view the document in another page. It has a problem when multiple documents are in the quote but you can relate each document either way.
I edited the file application/modules/quotes/views/view.php
And added these lines two lines above the stop dropzone.
<!-- Ver Archivo en URL -->
<?php
$filenames = glob('uploads/customer_files/' . $quote->quote_url_key . '*');
foreach ($filenames as $filename) {
$i=1;
echo '<p><a href="http://website.com/' . $filename . '" target="_blank">Abrir Archivo</a></p>';
$i=$i + 1;
}
?>
</div>
</div>
<!-- stop dropzone -->
It looks great and very usefull.
