{% flash %}
The {% flash %}
and {% endflash %}
tags will render any flash messages stored in the user session, set by the Flash
PHP class. The message
variable inside will contain the flash message text and the markup inside will repeat for multiple flash messages.
<ul>
{% flash %}
<li>{{ message }}</li>
{% endflash %}
</ul>
You can use the type
variable that represents the flash message type — success, error, info or warning.
{% flash %}
<div class="alert alert-{{ type }}">
{{ message }}
</div>
{% endflash %}
You can also specify the type
to filter flash messages of a given type. The next example will show only success messages, if there is an error message it won't be displayed.
{% flash success %}
<div class="alert alert-success">{{ message }}</div>
{% endflash %}
# Setting flash messages
Flash messages can be set by Components or inside the page or layout PHP section with the Flash
class.
function onSave()
{
// Sets a successful message
Flash::success('Settings successfully saved!');
// Sets an error message
Flash::error('Error saving settings');
// Sets a warning message
Flash::warning('There was a problem but no worries');
// Sets an informative message
Flash::info('Just a heads up about the settings');
}
