Using the flash messenger extension

Dot-twigrenderer extends Twig with functions that use functionality from dotkernel/dot-flashMessenger to list messages or partial messages.

public function renderMessages(
        ?string $type = null,
        string $channel = FlashMessengerInterface::DEFAULT_CHANNEL
    ): string; // empty response

public function function renderMessagesPartial(
        string $partial,
        array $params = [],
        ?string $type = null,
        string $channel = FlashMessengerInterface::DEFAULT_CHANNEL
    ): string;

renderMessagesPartial returns messages previously passed to dot-flashMessenger. The last 3 parameters can be omitted to list all messages sent to FlashMessenger.

• $partial is the template file name
• $params is an optional array of items (key-value) passed to the template file
• $type is an optional item that identifies a subkey of FlashMessenger's channel array
• $channel is an optional item that identifies FlashMessenger's channel

Example usage

{{ renderMessagesPartial('page:partial') }}
