Getting a user's object by user ID. I'd like to know how it's done.

aaronkent — Dec 30, 2014, 05:18 PM

I've looked at the doc for $modx->getUser() and it appears that only handles the logged in user and the only parameter is context.

I'm trying to get a user, not the logged in user, by their id, so I can do horrible things with their email address, like spam it. Just kidding, I need it for a Gravatar plugin I'm building and I'm too lazy to DL an existing plugin, install it, and smurf through code.

Already got the Gravatar link generator working and it's hungry for email addresses.

Can I use "getObject('User', $uid );"? Or is the class name Users like the table name? Also, would this be applicable to the user attributes table (i.e. $class = 'UserAttribures';)?

You'd have to use getOption() to set the MY_MODELPATH constant in order to use the custom System Setting, but I doubt if it involves significant overhead.

It was the classname that was messing me up. I was trying to use "User" and kept getting "Could not create object of type: User".

Thanks, donshakespeare, whitebyte.

BobRay, I couldn't have asked for a more thorough answer. Are you going to be teaching MODX College? I've signed up for it and am in such anticipation, it will be like Christmas when MODX College starts.

In regards to xPDO in general, couldn't I create a constant for the packagepath.modelpath so I don't need to call getOption every time to retrieve it?

I believe this would be much nicer looking...

$prefix = 'pre_';
$packagename ='myPackage';
$classname = 'myClass';

$modx->addPackage( $packagename, MY_MODELPATH, $prefix );

$modx->getObject( $classname, $where );

as opposed to this...

$prefix = 'pre_';
$packagename ='myPackage';
$classname = 'myClass';

$packagepath = $modx->getOption($packagename . '.core_path', NULL, $modx->getOption('core_path') . 'components/' . $packagename . '/');
$modelpath = $packagepath . 'model/';

$modx->addPackage( $packagename, MY_MODELPATH, $prefix );

$modx->getObject( $classname, $where );

I just eliminated two line of code. But, am I adding too much overhead by adding that modelpath as a constant?

I could call a snippet that adds the constant when I set the custom session variables.

FYI, if this code will run on a live site, it's a good practice to test the return values of the getObject() and getOne() calls before calling get() on those objects:

$user = $modx->getObject('modUser', $uid);
if ($user) {
   $username = $user->get('username');
   $profile = $user->getOne('Profile');
   if ($profile) {
       $email = $profile->get('email');
   }
}

If everything you want is in the user profile, you can make things faster by getting it directly rather than going through the user object:

$profile = $modx->getObject('modUserProfile', array('internalKey' => $uid));
if ($profile) {
   $email = $profile->get('email');
}

If all you want is the email, and if this will be happening a lot, you can make it *really* fast by doing this:

/* Get user Email */
$query = $modx->newQuery('modUserProfile', array(
    'internalKey' => $uid,
));
$query->select('email');
$email = $modx->getValue($query->prepare());

If you will be doing it with a bunch of users at once, you can speed it up further by only calling prepare() once and using a parameterized query: http://bobsguides.com/blog.html/2014/12/17/using-parameterized-prepared-statements-to-retrieve-data/.

Do you just want emails, or more data such as extended or custom user data?

$user = $modx->getObject('modUser', $id); // basic stuff like username and active/not active
$profile = $user->getOne('Profile'); // longname, phone number, etc

Won't this work for modUser?

http://bobsguides.com/revolution-objects.html
Finding Other Objects
In revolution, references to all MODX objects can be retrieved using the $modx->getObject() method.

You can "get" a MODX object like this:

$object = $modx->getObject('object-class-name',array(
       'name' => 'object-name' ));
Or, to get the object by ID number:
$object = $modx->getObject('object-class-name',$object-id);

Please don't spam them, only the bad ones...
