php.ini should be in the /wp-admin/ folder, not the root. Also, I’ve had success using a combination of the following in my /wp-admin/php.ini file AND a directive to increase the memory in my wp-config.php file, increased memory is needed when uploading larger files. Put something like this in your php.ini file (change values as you … Read more
Markup of that metabox is generated by _wp_post_thumbnail_html() function, contained in wp-admin/includes/post.php.
What you are trying to do is wrong if it is for general purpose use and is not tailored for the needs of a specific client. Dynamically modifying your theme’s code, and css is code like JS, is usually a bad idea that bring only maintenance problems – are you validating all values to be … Read more
Reading a file to send to the user is perfectly safe and does not necessarily need to be converted to the WP_Filesystem methods. Only writing is potentially an issue. However, if you wanted to do so, this would be the equivalent: echo $wp_filesystem->get_contents( filename variable here ); Also, note that your filename for “put_contents” is … Read more
It is not necessary to use the WP_Filesystem for every little thing, and in this case, the correct solution is to use the normal file_get_contents. The WP_Filesystem is a wrapper around various ways to interact with the filesystem in a safe manner… but it’s not meant for everything. Fundamentally, the WP_Filesystem code was created to … Read more
I would go with transient. The reason I would choose transient it is they are created exactly for your case. I know that you have your own removal functionality but why to repeat yourself? Another advantage would be that transient beneath use cache. If for some reason your will need to install object cache your … Read more

Users must be able to do things like create attachments and must not need to have admin access … Read more
WP_Filesystem abstraction is primarily meant for performing plugin/theme/core updates, especially in environments with restricted writes. As such it doesn’t really implement full range of possible file operations, as you noted there is no ability to write to the end of file in declared API. More so some possible implementations (depending on file system) might not … Read more
I had to dig pretty deep for this too, and eventually figured out some way to do this. in my solution I used the following: WP_Filesystem(); global $wp_filesystem; $wp_filesystem->exists( ‘/path/to/file’ ); //use any other functions available in the Filesystem API: @see https://developer.wordpress.org/reference/classes/wp_filesystem_direct/
Unfortunately the documentation about the Filesystem API is very basic. What you are looking for is the dirlist method/function of the WP_Filesystem_$method class(es). The only documentation about it is the docblock out of the WP_Filesystem_Base class: /** * Get details for files in a directory or a specific file. * * @since 2.5.0 * * … Read more
