function drupal_get_messages

drupal_get_messages($type = NULL, $clear_queue = TRUE)

Returns all messages that have been set with drupal_set_message().

Parameters

string $type: (optional) Limit the messages returned by type. Defaults to NULL, meaning all types. These values are supported:

• NULL
• 'status'
• 'warning'
• 'error'

bool $clear_queue: (optional) If this is TRUE, the queue will be cleared of messages of the type specified in the $type parameter. Otherwise the queue will be left intact. Defaults to TRUE.

Return value

array An associative, nested array of messages grouped by message type, with the top-level keys as the message type. The messages returned are limited to the type specified in the $type parameter, if any. If there are no messages of the specified type, an empty array is returned.
