CUNY Academic Commons

The link on the arabstages.org site is created by the plugin wp-posts-to-pdf. The plugin is no longer available on the Commons for activation; see #10858.

I've added Scott as a watcher to see if he has updated ideas about plugins that provide this functionality. In the linked ticket, he recommends Anthologize. But I don't think that's a good substitute - Anthologize requires users to create a PDF document manually, but I think the current use case is for automatically-generated PDFs of each single post.

On other projects, I've used dk-pdf and found it to be OK. https://wordpress.org/plugins/dk-pdf/ We don't currently have this plugin on the Commons. If Scott doesn't have other ideas about how it could be accomplished, perhaps we could add dk-pdf or something like it.

No, I don't think we have any PDF generator for single posts.

Hi Boone,

I tried this on two different sites and got the same error message, see screenshots.

"There has been a critical error on this website."

Any ideas?

The dk-pdf plugin is causing a fatal error when attempting to create the PDF:

Fatal error: Uncaught Mpdf\MpdfException: Temporary files directory "/wp-content/plugins/dk-pdf/tmp" is not writable in /wp-content/plugins/dk-pdf/vendor/mpdf/mpdf/src/Cache.php:23

By default, the dk-pdf plugin attempts to write files to the /wp-content/plugins/dk-pdf/tmp/ directory. However, our filesystem set up is restricted so this was causing the fatal error. Fortunately, the dk-pdf plugin has a filter on their temp directory so I just wrote a quick filter that allows for writing to the /wp-content/uploads/dkpdf/ directory: https://github.com/cuny-academic-commons/cac/commit/a619cbf486a76d5c1d60e1e8a29c92f677d92745. This fix is live and it looks like this allows for the dk-pdf plugin to render the PDF now.

Thanks Ray! I can see that this is working now!

Thanks for tracking this down so quickly, Ray!
