How can one update a theme on a live site without interruption?

I think i’m going to answer my own question: My problem #1 (no direct server access) is probably what makes this situation the most irritating; had that not been an issue, i think there would be a lot of additional options open to me. But given that limitation, creating and uploading ‘new’ themes seems to … Read more

How to side load an image from a service

Short answer, you don’t. Functions like sideload are for importing images into WordPress itself and using all the normal media library stuff. For images on an external service, use normal img tags. If you want to copy an image from a URL, you sideload it. Not otherwise.

post_parent is 0 when uploading new files

The reason was the post_id key simply missing from the upload query. It was there for the normal posts, but was being omitted in the custom-post-type uploads. No idea why.

It is called for attachments shortly before the attachment is inserted into the database in post.php. The following sample will append … Read more

How to set a Minimum Image Dimension for Uploading

The $file array doesn’t have anything that you’d be able to use, but $GLOBALS has some helpful information. You can uncomment the debugging line that contains $GLOBALS to see what it contains. I have added a guard clause to the top of the tc_handle_upload_prefilter function. This ensures that the file size checking code is only … Read more

What error logs can I check to see why plugin updates are failing?

In wp-config.php, set the following (if not already set): define( ‘WP_DEBUG’, true ); define( ‘WP_DEBUG_LOG’, true ); define( ‘WP_DEBUG_DISPLAY’, false ); @ini_set( ‘display_errors’, 0 ); This will make sure that on the site no error is shown, however, WordPress will log all errors in debug.log file inside the /wp-content/ directory.
