Members

Contains filters are case sensitive
Namesort descending Modifiers Type Description
context_condition::condition_met function Marks a context as having met this particular condition.
context_condition::condition_used function Check whether this condition is used by any contexts. Can be used to prevent expensive condition checks from being triggered when no contexts use this condition.
context_condition::editor_form function Context editor form for conditions.
context_condition::editor_form_submit function Context editor form submit handler.
context_condition::fetch_from_context function Retrieve options from the context provided.
context_condition::get_contexts function Retrieve all contexts with the condition value provided.
context_condition::options_form function Options form. Provide additional options for your condition.
context_condition::options_form_submit function Options form submit handler.
context_condition::settings_form function Settings form. Provide variable settings for your condition.
context_condition::__clone function Clone our references when we're being cloned.
context_condition::__construct function Constructor. Do not override.
context_condition_path::condition_form function Condition form.
context_condition_path::condition_form_submit function Condition form submit handler.
context_condition_path::condition_values function Omit condition values. We will provide a custom input form for our conditions.
context_condition_path::execute function Execute.
context_condition_path::match protected function Match the subject against a set of regex patterns. Similar to drupal_match_path() but also handles negation through the use of the ~ character.
