Question

I am trying to set a flash message in a subcontroller (a controller which is embedded in the view via {% render “…Bundle:Subscribe:widget” %}), however the flash message is not outputted in my main template. any ideas how to solve this?

Answer 1

I am doing it via javascript/jQuery:

var messages = "";
// collect flash messages of all widgets (=subcontroller actions)
$('.flash-message').each(function(){
    messages += $(this).html()+"<br/>";
    $(this).html("");
});
// set messages into the "flash message container"
if(messages){
    $('#flash-message span').html(messages);
}
// show the messages
if($('#flash-message span').html().trim()){
    $('#flash-message').hide().delay(20).fadeIn().delay(5000).fadeOut();
}
