Installation

Step 1: Download the FlashAlertBundle

Using Composer Add the following to the "require" section of your composer.json file:, _(*4)

    "ras/flash-alert-bundle": "dev-master"

And update your dependencies, _(*5)

    php composer.phar update

Using submodules Execute the following command on your project root: ``` bash $ git submodule add git@github.com:rasanga/FlashAlertBundle.git vendor/bundles/Ras/FlashAlertBundle $ git submodule update --init, _(*6)

### Step 2: Enable the bundle
Registers the bundle in your `app/AppKernel.php`:
```php
<?php
...
public function registerBundles()
{
    $bundles = array(
        ...
        new Ras\Bundle\FlashAlertBundle\RasFlashAlertBundle(),
        ...
    );
...

Step Optional, if you are not using composer: Configure the Autoloader

Add the following to your autoload.php:, _(*7)

<?php
...
'Ras' => __DIR__.'/../vendor/bundles',

Usage

Report flash alerts

Add the following PHP code to report an alert message:, _(*8)

    $this->get('ras_flash_alert.alert_reporter')->addError("Access denied");

Note: You can choose one of the following functions to call from $this->get('ras_flash_alert.alert_reporter'), _(*9)

    addSuccess()
    addError()
    addWarning()
    addInfo()

Display flash alerts

Add the following twig code where you want to display alert messages:, _(*10)

    {{ render_flash_alerts() }}

Note 1: The parent twig template would be the best place for displaying flash alerts, _(*11)

Configuration

The following parameters can be overriden in your config.yml or similar:, _(*12)

ras_flash_alert:
    template: '::flashAlerts.html.twig'     # defaults to 'RasFlashAlertBundle::layout.html.twig'
    isAddStyles: false                      # defaults to true
    isAddJsAlertClose: false                # defaults to true

These can also be passed as parameters in the view when rendering alerts - for example:, _(*13)

    {{ render_flash_alerts({ 'template': '::flashAlerts.html.twig', 'isAddStyles': false }) }}

Override view template

1. Crete template in the /Resources/views/ or in your bundle
2. Retrieve alerts into your template with {{ get_alert_publisher() }}
3. Include template blocks in FlashAlertBundle/Resources/views/FlashAlert directory or define your own blocks (follow FlashAlertBundle/Resources/views/FlashAlert/flashAlerts.html.twig to see how you can define your own template)

Add custom styles

The bundle default template has styles defined by default. However, you can turn off default styles by configuring isAddStyles variable to false as shown in below., _(*14)

    {{ render_flash_alerts({ 'isAddStyles': false }) }}

Then you can define your own styles to match alert classes such as alert, alert-close, alert-success, alert-error, alert-warning and alert-info, _(*15)
