Create scripts

sudo nano /home/pi/wjv-pause-pihole-5m.sh
	sudo /usr/local/bin/pihole disable 5m
sudo nano /home/pi/wjv-pause-pihole-10m.sh
	sudo /usr/local/bin/pihole disable 10m

Make executable

sudo chmod +x /home/pi/wjv-pause-pihole-*.sh

Install all scripts to root

sudo cp -v /home/pi/wjv-*.* /root/.

Create sudoers file, add lines

Allow webserver user to execute the scripts. 

sudo visudo /etc/sudoers.d/wjv-pause-pihole
	www-data ALL=NOPASSWD: /root/wjv-pause-pihole-5m.sh
	www-data ALL=NOPASSWD: /root/wjv-pause-pihole-10m.sh

sudo nano /var/www/html/wjv-pause-pihole.php
