@efk:
Can someone explain the proper/clean way to update the config.xml file in pfsense? I see some code meant to handle the XML, and i see write_config(), but I'm having a hard time putting it all together. A brief tour of the componants and a quick example would help me out immensely.
Thanks in advance!
From what I understand:
conf_mount_rw(); For making nanobsd read/write
global $config; For manipulating the config
$config['installedpackages']['packagename]['a']['b']['something'] = "something"; Array elements
write_config(); To write the config
conf_mount_ro(); For moving nanobsd back to read only
Example Code
function create_vnstati_image() {
conf_mount_rw();
global $config;
$iface = $_POST['vnstat_interface'];
$ifaces_final = convert_friendly_interface_to_real_interface_name($iface);
$config['installedpackages']['vnstat2']['config'][0]['vnstat_interface'] = $ifaces_final;
exec("/usr/local/bin/vnstati -i ". $ifaces_final ." -vs -o /tmp/newpicture1.png");
exec("/usr/local/bin/vnstati -i ". $ifaces_final ." -m -o /tmp/newpicture2.png");
exec("/usr/local/bin/vnstati -i ". $ifaces_final ." -d -o /tmp/newpicture3.png");
exec("/usr/local/bin/vnstati -i ". $ifaces_final ." -t -o /tmp/newpicture4.png");
write_config();
conf_mount_ro();
}
Matching Example XML
<installedpackages><vnstat2><config><monthrotate>1</monthrotate>
<vnstat_interface>em0</vnstat_interface>
<vnstat_phpfrontend>on</vnstat_phpfrontend>
<vnstat_interface2>em1</vnstat_interface2></config></vnstat2></installedpackages>
I think we multiple tags that are in the same xml hierarchical level you would then use an index element in the array
$config['installedpackages']['packagename]['testpackage']['config'][0]['something'] = "something in config 0";
$config['installedpackages']['packagename]['testpackage']['config'][1]['something'] = "something in config 1";
$config['installedpackages']['packagename]['testpackage']['config'][2]['something'] = "something in config 2";
<installedpackages><testpackage><config><something>something in config 0</something></config>
<config><something>something in config 1</something></config>
<config><something>something in config 2</something></config></testpackage></installedpackages>
