Members
Name |
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::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_context::execute | function | Execute. Overrides context_condition_path::execute | |
| context_condition_context::get_contexts | function | Retrieve all context conditions. Overrides context_condition::get_contexts | |
| 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::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. |
