function ctools_context_converter_selector in Chaos Tool Suite (ctools) 7

Same name and namespace in other branches

1. 6 includes/context.inc \ctools_context_converter_selector()

Create a select box to choose possible contexts.

This only creates a selector if there is actually a choice; if there is only one possible context, that one is silently assigned.

If an array of required contexts is provided, one selector will be provided for each context.

Parameters

$contexts: A keyed array of all available contexts.

$required: The required context object or array of objects.

array|string $default: The default value for the select object, suitable for a #default_value render key. Where $required is an array, this is an array keyed by the same key values as $required for all keys where an empty string is not a suitable default. Otherwise it is just the default value.

Return value

array A form element, or NULL if there are no contexts that satisfy the requirements.
