I'm trying to get a thumbnail to link to a PDF of the same name if the PDF exists, but to not link to anything if the PDF doesn't exist. Here's the code I have:\[code\]<?php if ( function_exists('has_post_thumbnail') && has_post_thumbnail() ) {$full_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'full') ;$pdf = substr_replace($full_image_url , 'pdf', strrpos($full_image_url[0] , '.') +1);$filename = $pdf[0];if (file_exists($filename)) {echo '<a href="' . $pdf[0] . '" title="' . the_title_attribute('echo=0') . '" . target="_blank" >';the_post_thumbnail('Full Size');echo '</a>'; }else {echo "The file $filename exists"; } }?>\[/code\]Currently, the else statement is just to prove whether or not it's finding the file. Which it seems to, as it displays \[code\]The file http://localhost/AWAD/wp-content/uploads/2012/03/+D.pdf exists\[/code\]. And if I get rid of the conditional, the post thumbnail displays with a link to the PDF. I just can't get the conditional to work. Can anyone spot why it's not working?
