TEMPORARY DIRECTORY: This is where plugin / theme authors can store temporary files and directories. When a temporary directory expires, the garbage collector will delete it.
* '''tmp_dir_create'''( $expiration, $primary_file )
* ==> string $absolute_path | WP_Error $error
* Create a temporary directory specifically for the plugin/theme defined by $primary_file.
* '''tmp_dir_info'''( $absolute_path, $with_listing = false )
* ==> array $tmp_info | WP_Error $error
* Get info about the temporary directory at $absolute_path.

Plugin Suspension: suspend and resume any WP plugin

This is a set of two dynamic enzymes useful for suspending and resuming another plugin.

Work in progress...


This would be the content of a post of yours. The thingy plugin would be filtering content as usual.

Simulation of a login functionality in Angular2, token based.
View Backend services in

In this gist I show a simple setup for helping me build the frontend of a backend functionality before programming the latter. In this case it is the login functionality.

On the login page there are three buttons to allow me to login with different credentials, so that I can see what the server would tell me in each case. That will guide me to understand how I want to program the frontend.

A couple of seconds after clicking each button I'll get a response from the server.

  1. the first button will cause an error response, which I show in a feedback field on the login page.
  2. the second and third buttons will cause an OK response, which I store in the auth key of the local storage system.
