regenerate thumbnails for PDF-s (since WP 4.7) about media-command HOT 8 CLOSED

Hi @gnanet,

This was implemented in wp-cli/wp-cli#3751

from media-command.

Sorry to follow-up with this, but if the functionality is already there, then i need to debug the concrete issue somehow, but with --debug i did not get any extra information:

wp --debug media regenerate 1038

Hi @gnanet,

GitHub issues are meant for enhancement requests and specific, reproducible bugs, not for general support questions. Bug reports need to be reproducible with a fresh WordPress install. If your issue only reproduces in your environment, then it's likely specific to your environment. For support options, please review http://wp-cli.org/#support

from media-command.

I will check the support options, and hope to find a way to get more debug info to see if it is reproducible, or only a separated issue. Thank you

I will have to inspect the condition of no metadata could be generated for PDFs if restricted to a specific image size because the PDF was imported by the media command, and initially no thumbnail got generated, and this happens also on regenerate, but no image size was manually specified.

from media-command.

I promise this is the last update, if i find any really reproducible bug i open a separate issue:

In the database i found no _wp_attachment_metadata field for the PDF in question, and manually adding a properly serialized value, based on other PDF-s did not help either. Then I used the nvola fork of force-regenerate-thumbnails which had no problems with the generation.

from media-command.

Can you provide steps to reproduce (including associated test data), please?

from media-command.

Ofcourse, not later than tomorrow late afternoon, because i have 117 PDF-s to be imported.
I will replay the process, document all steps including the relevant database content state on every step.

But I have a bad feeling that one of the plugins (most suspect is WP Download Manager Pro) hacks itself into the upload process as described in this stackoverflow comment which causing the wp_generate_attachment_metadata to return an empty array, but not die with some error.

from media-command.

I was having the same problem. After a bit of digging I realized that wp_generate_attachment_metadata() is failing silently when either wp_get_image_editor()
or $editor->save( $preview_file, 'image/jpeg' ); returns an error.

I have created a patch to fix this: https://core.trac.wordpress.org/ticket/35959
