How to get data from a Global Set in a plugin?

Question

I have a Global Set called "Settings" (handle = 'settings'); Within that I have a text field called "Address" (handle = 'address').

I have a function in my Plugin and I'd like to get the Address data.

In the front-end I would write this:

{{ settings.address }}

How can I get the same information in my plugin with PHP?

I've got as far as this:

$address = craft()->elements->getCriteria(ElementType::GlobalSet);

When I var_dump this array, I can see the address string. But I can't figure out how to filter down to the address correctly.

Thanks

You can use the GlobalsService service available with craft()->globals like so:

// Get the settings global set
$settings = craft()->globals->getSetByHandle('settings');

// Access the address field
var_dump($settings->address)

Or you could use ElementCriteria as you suggested:

// Get the GlobalSet element critera
$criteria = craft()->elements->getCriteria(ElementType::GlobalSet);
// Set the handle you want
$criteria->handle = 'settings';
// Find the settings set
$settings = $criteria->first();

// Access the address field
var_dump($settings->address)

You can access all fields on the $settings variable using this synthax.

If you want to get all values from a global set without having to specify each field handle you can do something like this:

$set = craft()->globals->getSetByHandle('globalHandleHere');
$fieldLayoutFields = $set->getFieldLayout()->getFields();

foreach ($fieldLayoutFields as $fieldLayoutField) {
    $field = craft()->fields->getFieldById($fieldLayoutField->fieldId);   
    $value = $set->getContent()[$field->handle];

    // Do whatever with $value here.
}
