Import scheduler for the plugin WP User Imports

Schedule-WP-User-Imports.php

<?php
/*
# v1.0.1
# 2021-08-06
#
# Extends WP plugin 'Import Users from CSV' to enable scheduled WordPress user imports
#
# This scheduler has been rolled into my fork of the Import Users from CSV plugin
# See https://github.com/VR51/import-users-from-csv
#
# This Gist ONLY works when the plugin 'Import Users from CSV' is installed into WordPress
# Plugin URL: https://github.com/andrewlimaza/import-users-from-csv
# If that plugin is not installed this Gist will do nada.
# 
# Read the comments to understand how to use this code snippet

/**
* Automate/Schedule userdata and usermeta imports using the plugin
* 'Import Users from CSV'
* See the plugin code here https://github.com/andrewlimaza/import-users-from-csv
*
* 1. Put this snippet into a functionality plugin or put into your child theme's functions.php file
* 2. Configure the import options for $import_file_location and $args. See code comments to find these variables
* 3. Load a page of your website to schedule a time for the cron job to first run
* 4. The cron job is set once only when a frontend page of your site is first loaded after this code is installed.
* 5. The cron job will run twice daily. This can be configured. See code comments to see how to configure the cron job
*
* TIP: Add the code to your site at the time of day that you want the file import to run each day.
* The scheduled autorun time will be the same time of day that this task first runs
