Message Type Constants

Each message type can be referred to by its constant: INFO, SUCCESS, WARNING, ERROR. For example: ``

Redirects

It's possible to redirect to a different URL before displaying a message. For example, redirecting back to a form (and displaying an error message) so a user can correct an error.

The preferred method of doing this is by passing the URL as the 2nd parameter:

``

A redirect is executed as soon as the message it's attached to is queued. As such, if you need multiple messages AND need to redirect then include the URL with the last message:

### Sticky Messages
By default, all messages include a close button. The close button can be removed, thus making the message sticky. To make a message sticky pass `true` as the third parameter:

``

![Sticky Info Message](http://mikeeverhart.net/php-flash-messages/assets/img/sticky-info.png)
![Sticky Success Message](http://mikeeverhart.net/php-flash-messages/assets/img/sticky-success.png)
![Sticky Warning Message](http://mikeeverhart.net/php-flash-messages/assets/img/sticky-warning.png)
![Sticky Error Message](http://mikeeverhart.net/php-flash-messages/assets/img/sticky-error.png)

There's also a special method, appropriately enough called `sticky()`, that can be used to make sticky messages:

``

`sticky()` accepts an optional 2nd parameter for the redirect url, and a 3rd for the message type:

`

By default, `sticky()` will render as whatever the default message type is set to (usually `$msg::INFO`.) Use the 3rd parameter override this.

## Helper Methods
### `hasErrors()`

Check to see if there are any queued `ERROR` messages.

``

### `hasMessages ( [string $type] )`

Check to see if there are any specific message types (or any messages at all) queued.

``

### `setCloseBtn ( string $html )`

Sets the HTML for the close button that's displayed on (non-sticky) messages.

``

### `setCssClassMap ( array $cssClassMap )`

Sets the CSS classes that are used for each specific message type.

``

### `setMsgAfter ( string $msgAfter )`

Add a string of text (HTML or otherwise) <b>after</b> the message (but <b>inside</b> of the wrapper.)

For example, wrap a message in `<p>` tags:

``

### `setMsgBefore ( string $msgBefore )`

Add a string of text (HTML or otherwise) <b>before</b> the message (but <b>inside</b> of the wrapper.)

For example, wrap a message in `<p>` tags:

``

### `setMsgCssClass ( [string $cssClass] )`

Sets the CSS class that is applied to all messages, regardless of their type.

``

### `setMsgWrapper ( string $html )`

Sets the HTML that wraps each message. HTML should include two placeholders (`%s`) for the CSS class and message text.

``

### `setStickyCssClass ( [string $cssClass] )`

Set the CSS class used for sticky messages
