Adding options to the web interface of a package - howto?

[yanl]

Hi,

I have some difficulties adding an option to squid's web interface (or any other packages).
Just for testing purpose, I would like to have a checkbox that let me add or remove a comment line in squid.conf

So far, I've modify these two files:

"/usr/local/pkg/squid_ng.xml"
<fields>…
    <field><fielddescr>Add a comment</fielddescr>
        <fieldname>testing_enabled</fieldname>
        <description>Some testing stuff.</description>
        <type>checkbox</type></field>
...</fields>

"/usr/local/pkg/squid_ng.inc"
function global_write_squid_config() {

...

$testing_enabled = $config['installedpackages']['squid']['config'][0]['testing_enabled'];

…

if (isset($testing_enabled) && ($testing_enabled == "on")) {
        $config_array[] = "# This is a test.\n";
    }

...

}

The comment line is add to squid.conf but is never removed when I uncheck the checkbox, and in /cf/conf/config.xml, "<testing_enabled></testing_enabled>" is always set to "on".

What did I miss?

you need to unset() the variable before doing the test.  That way its already deleted if the user does not enable the option.

$testing_enabled = $config['installedpackages']['squid']['config'][0]['testing_enabled'];

unset($config['installedpackages']['squid']['config'][0]['testing_enabled']);

write_config():

if (isset($testing_enabled) && ($testing_enabled == "on")) {
    $config_array[] = "# This is a test.\n";
}
