Filter users by a custom field?

Question

From within a plugin, I’m trying to filter users by a custom field.

An external post request will supply a variable which I want to match the custom field to. I then want to respond to that request with other user custom fields as JSON.

For example the incoming post contains customHandle1=A, I then find all the users where customHandle1=A and return customHandle2 and customHandle3 data.

How would I do that?

To get a user by a custom field, you would need to create a ElementCriteriaModel like this:

$criteria = craft()->elements->getCriteria(ElementType::User);
$criteria->fieldName = craft()->request->getPost('fieldName');

$users = $criteria->find();

you could then loop over $users and use getAttributes() to get the user data, and if you need the attribute names use attributeNames() if you need the users fields.
