1 layout.admin.inc | layout_condition_add_form($form, &$form_state, Layout $layout = NULL, Block $block = NULL, LayoutMenuItem $menu_item = NULL, $condition_id = NULL) |
Form callback; Displays form for adding new conditions to a layout or block.
Parameters
Layout $layout: The layout to which a condition is being added.
Block|null $block: If applying a condition to a particular block, the block instance.
LayoutMenuItem|null $menu_item: If applying a condition to an menu item, the menu item object.
int|null $condition_id: The integer ID of the condition being configured. If adding a new condition, no value will be passed in. Note that this value may be a FALSE-like value, such as 0, indicating the first condition is being configured, which is different than a NULL value indicating a new condition is being added.
