How to import a Policy from a xml in a snippet ?

junicool — Nov 29, 2015, 10:52 AM

Hello everybody !

I had exported a custom XML file Policy from the manager of a specific project.
I want to import this file dynamicly from a snippet in a new project. To do that, I used modAccessPolicy method.

here's my code :

$data = file_get_contents('custom.policy.xml');
$xml = simplexml_load_string($data, "SimpleXMLElement", LIBXML_NOCDATA);
$json = json_encode($xml);

$policy = $modx->newObject('modAccessPolicy');
$policy->set('data', $json);
$policy->save();

If any one could tell me the right way,
Thanks for your help

I'm glad it worked for you.

Actually, I think Markus Schlegel is the author of that bit of code, so he deserves most of the credit.

Your $xml variable is an object (not an array) and I suspect that it may need to be converted to an array, then used to set the fields of the Policy individually. I don't think you'll need json_encode() because the 'data' member is probably already JSON and it's the only JSON value in a Policy. You may also need to create a Policy Template and use its ID for the 'template' field of the Policy.

Here's what the Policy object looks like: http://bobsguides.com/modx-object-quick-reference.html#modAccessPolicy.

You might also look at the code of the NewsPublisher snippet. The third and fourth files here have code to create a Policy and Policy Template.

If you have a code editor that will let you run and debug php scripts (e.g., PhpStorm), you'll save a lot of time if you write the code in it and step through it to see what you're getting until you can get things in the correct form.
