How to run a script on "Save & Apply" click?

Installing and Using OpenWrt

Hi. I want to run an script each time an Apply is triggered from Luci. Where should I put my script?

singular or global?

@anon50098793 Thanks, sorry I don't understand very well what you're referring with singular or global. I already have the script, and I run it manually from SSH after I click on "Save & Apply" on Luci. What I want is to automate that run, so I don't need to login to SSH and manually run the script, but simply to run it automatically on each Apply.

changing luci is probably not the best way unless there is further interaction with the browser / page / page-s...

if you instantiate a service... with procd config.trigger's for all config's... you'll get luci+cmdline+manual edits...

Seems too complicated for my humble knowledge... I'll try to change my approach, and will do it with a cron job that detects changes in uci each minute.

What script?

The script i quite simple: It checks if all DHCP static hosts have a tag applied, and if not, it's applied, and dnsmasq is reloaded:

#!/bin/ash

i=1
check=1
change=0
while [ $check -eq 1 ]
do
  if [ $(uci get dhcp.@host[$i]) ]; then
    if [ $(uci get dhcp.@host[$i].tag) ]; then
      if [ $(uci get dhcp.@host[$i].tag) != 'unrestricted' ]; then
        uci set dhcp.@host[$i].tag='unrestricted'
        change=1
      fi
    else
      uci set dhcp.@host[$i].tag='unrestricted'
      change=1
    fi
    i=$(expr $i + 1)
  else
    check=0
  fi
done

if [ $change -eq 1 ]; then
  uci commit dhcp
  /etc/init.d/dnsmasq reload
fi

Options:

The latter is preferable.

Oh, I didn't know about these scripts. Is this reload function also invoked when an Apply is triggered from Luci?
