So i have lighttpd on my router hosting a very simple webpage. Whats the easiest/best way to have a button on the page that triggers a script execution on the router?

Right now I have a simple html button ( using form method="get" and button type="submit" ...etc.) with an action that loads a different html file. On that other html file I have an SSI command <!--#exec cmd="/opt/my_script.sh" --> that immediately runs my_script.sh. (I have lighttpd configured to load the mod_ssi module).

This is working perfectly fine. the only annoyance is that it needs to switch html files to execute the script.

Is there a simpler way to have a button directly execute a script?

Thanks for any insights! and yes I know SSI is a relic of the 1990's, but it seems to work fine for me Smile. Although if there is a better way to do it thats just as easy I am all ears

Php is a very easy and lightweight way to do it.

assuming you have entware, use opkg to install the PHP module.

in your html file you would add something like this:
Code:

       <?php
      if(array_key_exists('button1', $_POST)) {
            button1();
        }
        function button1() {
        shell_exec("/opt/your_script.sh");
      }
       ?>



search google for "php shell_exec examples"
