ResolveInfo::getFieldSelectionWithAliases │ public │ WC 1.0

Returns names and args of all fields selected in query for $this->fieldName up to $depth levels, including aliases.

The result maps original field names to a map of selections for that field, including aliases. For each of those selections, you can find the following keys:

  • "args" contains the passed arguments for this field/alias (not on an union inline fragment)
  • "type" contains the related Type instance found (will be the same for all aliases of a field)
  • "selectionSet" contains potential nested fields of this field/alias (only on ObjectType). The structure is recursive from here.
  • "unions" contains potential object types contained in an UnionType (only on UnionType). The structure is recursive from here and will go through the selectionSet of the object types.

Example: { root {

id
nested {
 nested1(myArg: 1)
 nested1Bis: nested1
}
alias1: nested {
  nested1(myArg: 2, mySecondAg: "test")
}
myUnion(myArg: 3) {
  ...on Nested {
	nested1(myArg: 4)
  }
  ...on MyCustomObject {
	nested3
  }
}

} }

Given this ResolveInfo instance is a part of root field resolution, $depth === 1, and fields "nested" represents an ObjectType named "Nested", this method will return: [

'id' => [
	'id' => [
		 'args' => [],
