I am currently creating a module on Grav but I have a problem.
Yaml :
table:
-
title: Test
content:
-
value: 'test1'
-
value: 'test2'
-
value: 'test3'
Twig :
{% for item in page.header.table.content %}
<h1>{{item.value}}</h1>
{% endfor %}
I can not display 'value'
but if I do :
{% for item in page.header.table %}
<h1>{{item.title}}</h1>
{% endfor %}
title is displayed correctly
Because Table is an array of object
https://twigfiddle.com/jbde9m
{% for item in page.header.table %}
<h1>{{item.title}}</h1>
{% endfor %}
{# you can also do for item in page.header.table.0.content #}
{% for item in (page.header.table|first).content %}
<h1>{{item.value}}</h1>
{% endfor %}

I've this template code in Symfony:
{{ form_widget(registrationForm.username, {'attr': {'class': 'form-control'}}) }}
{{ form_errors(registrationForm.username) }}
Instead of just displaying error text, it's generating a list item like this:
<ul><li> Username already exists </li></ul>
How to not have it generate this list item and just get the text?
I guess it is correct behavior, cause you can have multiple errors for one field for example "Username is too short" and "Field Username contains inappropriate characters", but to get only first error you can use:
{{ form_errors(registrationForm.username|first) }}
Or you can customize your form_errors rendering, first create file for form_errors, for example your_form/custom_form_errors.html.twig :
{% block form_errors %}
{% spaceless %}
<div class="error">{{ errors|first }}</div>
{% endspaceless %}
{% endblock %}
And after that include it to your view file:
{% form_theme form 'your_form/custom_form_errors.html.twig' %}
...
{{ form_errors(registrationForm.username) }}
just to extend #Andrii Filenko 's answer. You can modify the output the form_errors or any other form twig function pretty easily. it's called custom theming in Symfony.
Consider this:
// templates/register.html.twig
{% extends "base.html.twig" %}
{% form_theme registrationForm _self %}
{% block form_errors %}
{% spaceless %}
{% if errors|length > 0 %}
<ul class="changed list">
{% for error in errors %}
<li>{{ error.message }}</li>
{% endfor %}
</ul>
{% endif %}
{% endspaceless %}
{% endblock form_errors %}
{% block body %}{% endblock %}
Output:
<ul class="changed list"><li> Username already exists </li></ul>
A little question : how can I change < title > < /title > with Sonata Admin ?
Everywhere there is "Admin...". And when I override a page with sonata template I got "Admin".
Thank's.
You can easy do that by override the sonata admin file translation
1- Create folder structure in traslations like this :
2- then in the SonataAdminBundle.[your-language-code].yml file add :
Admin: "You Custom title Here"
You have to override Sonata admin's standard_layout.html.twig file to achieve this.
First, define the file in sonata admin config file.
config/packages/sonata_admin.yaml
sonata_admin:
templates:
layout: 'sonata_admin/layout.html.twig'
Create a twig file named layout.html.twig inside templates/sonata_admin/ and just paste the sonata_head_title block from the bundle.
{% extends '#SonataAdmin/standard_layout.html.twig' %}
{% block sonata_head_title %}
{{ 'Admin'|trans({}, 'SonataAdminBundle') }} //remove this line to get rid of text "Admin"
{% if _title is not empty %}
{{ _title|striptags|raw }}
{% else %}
{% if action is defined %}
-
{% for menu in breadcrumbs_builder.breadcrumbs(admin, action) %}
{% if not loop.first %}
{% if loop.index != 2 %}
>
{% endif %}
{%- set translation_domain = menu.extra('translation_domain', 'messages') -%}
{%- set label = menu.label -%}
{%- if translation_domain is not same as(false) -%}
{%- set label = label|trans(menu.extra('translation_params', {}), translation_domain) -%}
{%- endif -%}
{{ label }}
{% endif %}
{% endfor %}
{% endif %}
{% endif %}
{% endblock %}
So I have Twig running on top of Symfony 2.7. In the output html I'd like to have a few modules of text and in the last module I want some summary from all the previous ones (some data from all the previous modules' Entities) and I figured I'd append these summaries to a global variable while generating modules themselves to avoid a second loop. The code I'm using:
{% extends 'base.html.twig' %}
{% set list = '' %} {# HERE I SET A GLOBAL VAR #}
{% block body %}
<section>
<h2>{% trans %}MODULES{% endtrans %}</h2>
{% for m in plan.Modules %}
{{- block('module') -}}
{{ list }} {# HERE JUST FOR TESTING - IT'S EMPTY #}
{% endfor %}
</section>
{{ list }} {# HERE I WANT IT DISPLAYED, YET IT'S EMPTY :( #}
{% endblock %}
{% block module %}
<h3>{{ m.Module.title }}</h3>
{# HERE SOME MODULE TEXT I GET FROM COMPLICATED RELATIONS #}
{% if m.Module.list %}
{% set temp %}
{{ m.Module.shortTitle }}<br/>
{% endset %}
{% set list = list~temp %}
{% for l in m.Module.list %}
{% set temp %}
{{ l }}
{% endset %}
{% set list = list~temp %}
{% endif %}
{% endfor %}
{% endif %}
{{ list }} {# HERE IT'S WORKING #}
{% endblock %}
Any ideas?
I'am using following code to set selectedGallery to a defaultValue. The default Value should be galleryData's first Element.
Sadly it doesn't work. selectedGallery does not exist after the snipped run through...
Thanks for help
{% if selectedGallery is not defined %}
{% for gallery in galleryData|keys|slice(0, 1) %}
{% set selectedGallery = gallery %}
//if i access galleryData here, it exists ?!
{% endfor %}
{% endif %}
later the same file:
<div id="{{idPref}}PictureBox" class="backA">
{% block pictureBox %}
{% for picture in galleryData[selectedGallery] %}
{{selectedGallery}}
{% endfor %}
{% endblock %}
Symfony says that the variable doesn't exists.
Try:
First:
{% if selectedGallery is not defined %}
{% set selectedGallery = galleryData|keys|first %}
{# ... #}
http://twig.sensiolabs.org/doc/filters/first.html
Later:
<div id="{{idPref}}PictureBox" class="backA">
{% block pictureBox %}
{% for picture in attribute(galleryData, selectedGallery) %}
{{picture}}
{% endfor %}
{% endblock %}
{# ... #}

I'm learning Symfony2. Currently, I'm trying to render a form label in a twig template. The label includes an html tag, that is not rendered correctly in my twig file.
Here follows the piece of code where the form field is created:
$builder->add('zipcode', 'integer', array(
'label' => '<abbr title="Zone Improvement Plan">CAP</abbr> code',
));
In the twig file I render the field label as follows:
{{ form_label(form.zipcode) }}
I tried the raw, escape, e filters, but the results provided in my html page is always the string
<abbr title="Zone Improvement Plan">CAP</abbr> code
and not the corresponding HTML code!
Any suggestion?
Thanks in advance!
Later I found the solution.
The solution is to disable the autoescape within the label block provided by Symfony at path:
symfony / src / Symfony / Bridge / Twig / Resources / views / Form / form_div_layout.html.twig
So, in your twig file you have to put the following lines outside the form:
{% form_theme form _self %}
{% block generic_label %}
{% spaceless %}
{% if required %}
{% set attr = attr|merge({'class': attr.class|default('') ~ ' required'}) %}
{% endif %}
<label{% for attrname,attrvalue in attr %} {{attrname}}="{{attrvalue}}"{% endfor %}>{% autoescape false %}{{ label|trans }}{% endautoescape %}</label>
{% endspaceless %}
{% endblock %}
From JeanValjean himself :
{% autoescape false %}{{ form.zipcode.vars.label | trans }}{% endautoescape %}
And to generalize this behaviour to your whole app, you can override the form block for labels :
{% block generic_label %}
{% spaceless %}
{% if required %}
{% set attr = attr|merge({'class': attr.class|default('') ~ ' required'}) %}
{% endif %}
<label{% for attrname,attrvalue in attr %} {{attrname}}="{{attrvalue}}"{% endfor %}>
{% autoescape false %}{{ label|trans }}{% endautoescape %}
</label>
{% endspaceless %}
{% endblock %}
To disable the autoespace filter just to render a variable is not the best thing because when you read the code it's not really clear.
So, instead of :
{% autoescape false %}{{ label|trans }}{% endautoescape %}
You can use :
{{ label|trans|raw }}
