[Plugin: Latex Everything] PDFs generated but not linked to articles

Is the problem that the PDF isn’t being attached to the post, or that a link to the PDF isn’t being inserted into the post.

You can tell whether the PDF of a single post been attached to the post in question by going to Media->Library in the admin section and looking at the “Attached to” column. You should see that a PDF with a titles such as “My First Post” will be attached to the post “My First Post”. PDFs for categories, tags, taxonomies and posts types won’t be attached to anything. Tell me if this isn’t working, because it should be.

If the problem is that a link to the PDF isn’t being inserted into the post, have you made sure you’ve added code for the link into the theme? This can be found in the plugin’s FAQ. For example, here’s the code you should put in The Loop.

<?php if( function_exists('get_latex_url')
          && $latex_url = get_latex_url( 'single_post', get_the_ID() ) ): ?>
<a href="<?php echo $latex_url ?>">PDF</a>
<?php endif; // get_latex_permalink ?>

If you have put some code like this in, and you’re still not getting a link to the PDF, could you tell me exactly what you have written, and what result it produces?

Hi, the problem is that PDFs don’t get attached to posts. I look into Multimedia and doesn’t see any PDFs, but the PDFs are generated inside /tmp.

If I create a NEW post and enter a title but no text, the autosave feature of the edit screen triggers the plugin, and it generates a PDF file named “.pdf” that gets attached to the post. When some text is entered and the post is saved, then all works well and a new PDF gets attached to the post.

The problem is that it doesn’t work with existing posts. When I hit update the PDF gets generated inside /tmp but doesn’t get attached to the post.

Disabling and enabling the plugin does generate all PDFs again inside /tmp, but doesn’t attach them to their posts.

I have changed my code for displaying PDFs to match yours (I did this before):

get_latex_url( 'single_post', get_the_ID() ) ): ?>
<a href="<?php echo $latex_url ?>">PDF</a>

and obviously now the link is not visible. Previously it generated a link to the post when it couldn’t attach the PDF.

I’ve tested the creation of PDFs with WordPress 3.3.1, and I indeed can’t get the PDFs to be created. It’s well broken. I haven’t got time right now to fix it though – I’ll post here when I get around to it.

In fact, I can guarantee you that I cannot fix it until after the 17th of March 2012 (11 days from now). I’ll figure out what’s wrong after that though.

It’s OK, thanks for caring!

My install of Latex Everything has mysteriously started working again, and I can’t identify anything I’ve done to make it do so, so I’m afraid I can’t reproduce your problem.

If you’ve move on and don’t care about fixing the problem, that’s fine – it’s less work for me as well :). If you’d still like to fix it enable debugging in WordPress by adding the following to wp-config.php:

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

Try to generate a PDF again, and tell me if any errors appear in wp-content/debug.log.
