im try get flashData in a Twig template. In the controller i set:
$session = $this->getRequest()->getSession();
$session->getFlashBag()->add('ok_menu', true);
$session->getFlashBag()->add('msg_menu', 'Las selecciones del menu fueron guardadas correctamente.');
And in the profiler, are displayed:
In the template i write this:
{% if app.session.get('ok_menu') is defined %}
{% if app.session.get('ok_menu') %}
<div class="alert alert-success">
<strong>Éxito:</strong> {{ app.session.get('msg_menu') }}
</div>
{% endif %}
{% endif %}
But, in the page not reder the flash messages.
Any ideas ?.
You probably need to access the values from the flashbag property.
{% if app.session.flashbag.has('ok_menu') %}
{% if app.session.flashbag.get('ok_menu') %}
<div class="alert alert-success">
<strong>Éxito:</strong> {{ app.session.flashbag.get('msg_menu') }}
</div>
{% endif %}
{% endif %}

I would like to include tab_system.twig file in two differents files : archive.twig and blog_list.twig to have the same html in those two files.
{% include "tab_system.twig" %}
In this tab_system.twig file I have a condition to add the active class :
{% if XXX %}active{% endif %}
But this condition must be different depending on which page the user is.
For blog_list.twig :
{% if loop.first %}active{% endif %}
For archive.twig :
{% if item.term_id == term_page.term_id %}active{% endif %}
I wrote this without success :
{% set addclass = '' %}
{% if is_blog_list %}
{% set addclass = '{% if loop.first %}active{% endif %}' %}
{% elseif is_archive %}
{% set addclass = '{% if item.term_id == term_page.term_id %}active{% endif %}' %}
{% endif %}
In tab_system.twig I have a tab system with menu from a part and content to the other part. I wrote a js loop to display the corresponding content. I need to add active class on the first link and first content tab in blog_list.twig file and to add active class to the link and content tab depending on which category the user is.
<div class="tab-menu-list">
{% for item in all_posts %}
<a href="#" class="tab-menu {{ addclass }}"</a>
{% endfor %}
</div>
<div class="tab-content-list">
{% for item in all_posts %}
<div href="#" class="tab-content {{ addclass }}"</div>
{% endfor %}
</div>
is_archive and is_blog_list are variables defined elsewhere. They work
How can I create a condition ? Thank you in advance.
As I'm assuming you are looping the records, I'd say don't overcomplicate things,
single.twig
{% for i in 1..5 %}
{% include 'article.twig' with { 'active' : loop.first, } %}
{% endfor %}
template_blog.twig
{% for item in items %}
{% include 'article.twig' with { 'active' : item.term_id == term_page.term_id, } %}
{% endfor %}
article.twig
<div class="articles__list tab-content{{ active ? ' active'}}">
foo
</div>
demo - just change the main template
If you really wanted to keep that for inside the article template, which I think is not a great idea, you could still use the variables is_archive and is_blog_list inside article, e.g.
article.twig
{% for item in items %}
{% if is_archive %}
{% set active = loop.first %}
{% elseif is_blog_list %}
{% set active = item.term_id == term_page.term_id %}
{% endif %}
<div class="articles__list tab-content{{ active ? ' active'}}">
{% endfor %}
In symfony 4.1
In the controler:
$this->addFlash(
'notice',
'Your changes were saved!'
);
return $this->render(...);
Twig base template:
{% for message in app.flashes('notice') %}
<div class="flash-notice">
{{ message }}
</div>
{% endfor %}
That works fine, but I want to wrap ALL messages in a div. The below does not work:
{% if app.flashes is not empty %}
<div id="messageBox" class="overlay">
<div class="message" onclick="slide(document.querySelector('#messageBox')); this.classList.add('fadeAway');">
{% for label, messages in app.flashes %}
<section class="{{ label }}">
<p><b>{{ label }}</b></p>
<ul>
{% for message in messages %}
<li>{{ message }}</li>
{% endfor %}
</ul>
</section>
{% endfor %}
</div>
</div>
{% endif %}
The problem is that the line {% if app.flashes is not empty %} erases the messages, so the following for loops and empty result.
How do I use peekAll() for the if logic?
The correct way to check with peekAll() is {% if app.session.flashbag.peekAll() is not empty %} This will not clear the flashBag as per documentation.
I do not know if this is the best way to do this, but the following is my solution.
In the base.html.twig:
{% set flashes = app.flashes %}
{% if flashes is not empty %}
<div id="messageBox" class="overlay">
<div class="message" onclick="slide(document.querySelector('#messageBox')); this.classList.add('fadeAway');">
{% for label, messages in flashes %}
<section class="{{ label }}">
<p><b>{{ label }}</b></p>
<ul>
{% for message in messages %}
<li>{{ message }}</li>
{% endfor %}
</ul>
</section>
{% endfor %}
</div>
</div>
{% endif %}
Basically, set the returned value of app.flashes to flashes and handle that.
I'm trying to set flash message from ContactAction then redirect on Homepage, but on it, I can't see my flash message, maybe my session is reset ? Can I have some help, I'm a beginer on Symfony.
CoreController that contain both index and contact functions :
<?php
namespace OC\CoreBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
class CoreController extends Controller
{
public function indexAction()
{
$ServiceAdverts = $this->container->get('oc_core.listAdverts');
$adList = $ServiceAdverts->getListAdverts();
return $this->render("OCCoreBundle:Core:index.html.twig", array(
'listAdverts' => $adList
));
}
public function contactAction()
{
$this->addFlash('info', 'Contact page not ready yet !');
return $this->redirectToRoute('oc_core_homepage');
}
}
Twig template (homepage) :
{% block body %}
<div>
Messages flash :
{% for msg in app.session.flashBag.get('info') %}
<div class="alert alert-success">
{{ msg }}
</div>
{% endfor %}
</div>
<h2>Liste des annonces</h2>
<ul>
{% for advert in listAdverts %}
<li>
<a href="{{ path('oc_platform_view', {'id': advert.id}) }}">
{{ advert.title }}
</a>
par {{ advert.author }},
le {{ advert.date|date('d/m/Y') }}
</li>
{% else %}
<li>Pas (encore !) d'annonces</li>
{% endfor %}
</ul>
Contact
{% endblock %}
Symfony 3.3 made improvements to flash messages so your Twig template should look different. The app.session.flashBag.get() call is now replaced by app.flashes().
So your Twig code would now be:
{% for msg in app.flashes('success') %}
<div class="alert alert-success">
{{ msg }}
</div>
{% endfor %}
Try this, works for me in 3.2 and 3.4
{% for type, flash_messages in app.session.flashBag.all %}
{% for msg in flash_messages %}
<div class="alert alert-{{ type }}">
{{ msg }}
</div>
{% endfor %}
{% endfor %}
Another thing is that once you called the flashBag it turns empty so you can't use it twice. Check your code that it hasn't been called on another page right before a second redirect ...
I used the nl2br filter like this:
{{ knp_pagination_render(requests)|raw|nl2br}}
It prints the html object separated by a few line breaks, and I need to print all the objects in one single line. How can I reach that?
Any help would be great.
{{ string | replace({"\\n":""}) }}
See fiddle.
I suggest you to override the default pagination template, so you can customize how to generate the underling HTML code.
As described in the doc You can do simply:
{{ knp_pagination_render(request, 'MyBundle:Pagination:pagination.html.twig') }}
You can copy the current pagination implementation from here and customize it as you need.
This is the default implementation:
{# default Sliding pagination control implementation #}
{% if pageCount > 1 %}
<div class="pagination">
{% if first is defined and current != first %}
<span class="first">
<<
</span>
{% endif %}
{% if previous is defined %}
<span class="previous">
<
</span>
{% endif %}
{% for page in pagesInRange %}
{% if page != current %}
<span class="page">
{{ page }}
</span>
{% else %}
<span class="current">{{ page }}</span>
{% endif %}
{% endfor %}
{% if next is defined %}
<span class="next">
>
</span>
{% endif %}
{% if last is defined and current != last %}
<span class="last">
>>
</span>
{% endif %}
</div>
{% endif %}
I have a twig template with the following block:
{% block dashboard %}
{% include "::user_dashboard.html.twig" %}
{% endblock dashboard %}
Later in that template, I want to set a class on a div based on whether or not there is anything in that block (i.e., by default, it will have the include above, but children of this template may override it and empty it out).
What I had (that somewhat worked) was ...
{% set _dashboard = block('dashboard') %}
{% set _mainWidth = ( _dashboard|trim is empty ? "no-dashboard" : "with-dashboard" ) #}
<div id="main" class="{{ _mainWidth }}">
The problem here is that whole dashboard block gets called twice. This wouldn't bother me too much except that block renders a few controller actions, i.e. ...
{% render "UserWidget:userAppMenu" %}
... and the code in that action is being called twice. For various reasons, not the least of which is performance, this messes with some of the stuff in that dashboard block.
So, my question is ... is there any way to tell if that block is empty without loading it twice? Is there something really simple I'm missing or is this even possible?
Thanks!
EDIT:
Here is my full template if it helps clarify things:
{% extends '::base.html.twig' %}
{% block layout %}
{% block header %}
{% include "::header.html.twig" %}
{% endblock header %}
<div id="container" class="row-fluid">
{% block dashboard %}
{% include "::user_dashboard.html.twig" %}
{% endblock dashboard %}
{% set _dashboard = block('dashboard') %}
{% set _mainWidth = ( _dashboard|trim is empty ? "no-dashboard" : "with-dashboard" ) %}
<div id="main" class="{{ _mainWidth }}">
<h1 class="page-title">{% block page_title %}{% endblock %}</h1>
{% block main_filters %}{% endblock %}
{% if app.session.flashbag.has('message') %}
<div class="alert alert-block alert-success">
<ul>
{% for flashMessage in app.session.flashbag.get('message') %}
<li>{{ flashMessage }}</li>
{% endfor %}
</ul>
</div>
{% endif %}
{% if app.session.flashbag.has('warning') %}
<div class="alert alert-block alert-success">
<ul>
{% for flashWarning in app.session.flashbag.get('warning') %}
<li>{{ flashWarning }}</li>
{% endfor %}
</ul>
</div>
{% endif %}
{% block body %}{% endblock %}
{% block footer %}
{% include "::footer.html.twig" %}
{% endblock footer %}
</div>
</div>
{% endblock layout %}
Here you can see on lines 11 and 15 - both of those actually seem to include and process what is in that include.
What about this? This way the block should only be rendered once, when you call block('dashboard').
{# at top of twig #}
{% set _dashboard = block('dashboard') %}
{# where ever you include your block #}
<div>
{{ _dashboard|raw }}
</div>
{# and your main #}
{% set _mainWidth = ( _dashboard|trim is empty ? "no-dashboard" : "with-dashboard" ) #}
<div id="main" class="{{ _mainWidth }}">
