Loading field_collection values in templates
Field collection is a great module to have some sort of a bundle of fields in a form. Thus you can build a form field with mulitple values that itself has more than one fields attached. Maybe more about this module in another blogpost.
If you want to load the values of a field collection entity (just if you need it in an template for example) you can use entity_metadata_wrapper():
<?php $wrapper = entity_metadata_wrapper('node', $node); // In case of a non-multiple collection and an example text field, you could get the text via print $wrapper->field_collection->field_example->value(); // In case of a multiple collection and an example text field, you could get the text of the first one: print $wrapper->field_collection->field_example->value(); // and so one.. ?>
Or you load the value with entity_load():
<?php $field_collection = entity_load('field_collection_item', array(FIELD COLLECTION ITEM ID)); ?>
