How can i distinguish between field errors and bubbled (form) errors? AFAIK the only block that controls this is:
{% block field_errors %}
{% spaceless %}
{% if errors|length > 0 %}
<ul>
{% for error in errors %}
...
{% endfor %}
</ul>
{% endif %}
{% endspaceless %}
{% endblock field_errors %}
I think i can't rely on errors|length: usually it's 1 for field errors, but can be 1 also for form errors :(
To me it looks like by default you are unable to separate these errors. But you can extend the basic FormError class and add some property, which will define the exact place where error appeared.

I have a container for all of my flashmessages that is outside of the FOR statement which gets displayed even if there are no flash messages available.
Code below does its job perfectly, i just want to prevent the container from being displayed if there are no flashes to display. I'm trying to find a way to make a Twig IF to test it.
<div class="flashMsgContainer">
{% for flash_message in app.session.flashBag.get('success') %}
{# more code #}
{% endfor %}
{% for flash_message in app.session.flashBag.get('warning') %}
{# more code #}
{% endfor %}
{# more code #}
</div>
You can test flashes length without clear it with this code :
{% if app.session.flashbag.peekAll()|length > 0 %}
You could test the length of your flashbag.
{% if (app.flashes | length) > 0 %}
<div class="flashMsgContainer">
{% for label, messages in app.flashes %}
{% for message in messages %}
{# more code #}
{% endfor %}
{% endfor %}
</div>
{% endif %}
In your example, I guess that you could do it with app.session.flashBag, because it's certainly implementing Iterable.
I have the following twig template (the code is in the same file):
{% macro renderJob(fields) %}
// renders the job UI block, but I've removed it for simplicity
Hello world.
{% endmacro %}
{% block _jobs_widget %}
<div id="jobsContainer">
{% for fields in form.children %}
{% dump fields %}
{{ _self.renderJob(fields) }}
{% endfor %}
</div>
{% endblock %}
For some reason, after upgrading to twig/twig = v2.1.0 I'm receiving the follwing error:
Impossible to invoke a method ("renderJob") on a string variable ("#AppBundle/Jobs/form/job.html.twig").
I have been trying to figure out what's causing this without any luck. This used to work just fine in 1.3.x. The fields variable contains the proper data, but it appears it can't pass it to the renderJob macro or it can't find the macro (which is kind of odd)?
Have you tried the following ?
{% import _self as renderJobMacro %}
{% macro renderJob(fields) %}
// renders the job UI block, but I've removed it for simplicity
Hello world.
{% endmacro %}
{% block _jobs_widget %}
<div id="jobsContainer">
{% for fields in form.children %}
{{ renderJobMacro.renderJob(fields) }}
{% endfor %}
</div>
{% endblock %}
I think _self is depricated from twigg 2.0, May be you need to check without _self.
Check {{ renderJob(fields) }} instead of {{ _self.renderJob(fields) }}
How do I globally change the way form validation errors are displayed in Symfony2? For example, if I want to wrap each one of my error messages in a <span class="error"> or something like that, how would that be done?
Note: I'm aware of this question/answer, but I'm not sure that it's the same question as mine, and I don't understand how to apply the selected answer.
Take a look at the docs: custom global theme, customizing error output
{# SomeBundle:Layout:fields.html.twig #}
{% block field_errors %}
{% spaceless %}
{% if errors|length > 0 %}
<span class="error">
{% for error in errors %}
{{ error.messageTemplate|trans(error.messageParameters, 'validators') }}<br />
{% endfor %}
</span>
{% endif %}
{% endspaceless %}
{% endblock field_errors %}
{# In your form template #}
{% form_theme form 'SomeBundle:Layout:fields.html.twig' %}
I'm designing a multi-tenant application with Symfony2, There will be common templates and each tenant could have custom templates. I would like create a theme folder like this(like wordpress with css,img,etc...) :
Themes/commons/base.twig.html
Themes/commons/css/styles.css
Themes/commons/js/script.js
Themes/tenantID/base.twig.html
Themes/tenantID/css/styles.css
Themes/tenantID/js/script.js
Perhaps I'm taking a wrong way...?
Any suggestion ?
Thanks.
There is nothing wrong with your design. I may name "commons" as "default" but thats up to you. Approach with tenantid looks good to me. Whats your question?
https://github.com/fabpot/Twig/issues/17 - no dynamic inheritance
LiipThemeBundle might be a solution: http://symfony2bundles.org/liip/LiipThemeBundle
You can achieve all this by following symfony standard . because if you follow structure you will make full stack full site in frame work and you can also learn how to use frame work.
like in
bundle folder:
userbulndle/css
userbulndle/js
adminbundle/css etc
and use theme forming
{% block gender_widget %}
{% spaceless %}
{% if expanded %}
{% for child in form %}
<div class="radio_ele">
{{form_widget(child) }}
{{form_label(child) }}
</div>
{% endfor %}
{% else %}
{{ block('choice_widget') }}
{% endif %}
{% endspaceless %}
{% endblock %}
{# ----------------------------------------------------------- #}
{% block field_errors %}
{% spaceless %}
{% if errors|length > 0 %}
<div class="error_list">
{% for error in errors %}
{{ error.messageTemplate|trans(error.messageParameters, 'validators') }}
{% endfor %}
</div>
{% endif %}
{% endspaceless %}
{% endblock field_errors %
This ยง of the Symfony2 documentation shows an awesome technique for customizing an individual field. I'm using it a lot but there is one particular Type for which I'm having a hard time doing the customization : the CollectionType() Customizing the collection itself is quite easy, you can do something like this:
{% block _mynamespace_mybundle_mytype_mycollectionfield_row %}
{% if prototype is defined %}
{% set attr = attr|merge({'data-prototype': form_widget(prototype) }) %}
{% endif %}
{% spaceless %}
<ul {{ block('widget_container_attributes') }}>
{% spaceless %}
{{ form_errors(form) }}
{% for child in form %}
<li>
{{form_widget(child)}}
</li>
{% endfor %}
{% endspaceless %}
{{ form_rest(form) }}
</ul>
{% endspaceless %}
{% endblock %}
But how can you customize each element of the collection ? And how can you customize the data-prototype using Twig (the data-prototype is a special attribute used to add new items with js)?
I tried doing something like this (for the data-prototype):
{% block _mynamespace_mybundle_mytype_mycollectionfield_$$name$$_row %}
customization ok!
{% endblock %}
But I get errors, because I don't know how to escape the $
Regarding the items, I tried many things:
{% block _mynamespace_mybundle_mytype_mycollectionfield_item_subfield_row %}
customization ok!
{% endblock %}
{% block _mynamespace_mybundle_mytype_mycollectionfield_element_subfield_row %}
customization ok!
{% endblock %}
None of them work.
I asked the question in symfony's bug tracker, and it seems there is no solution, but a good workaround is creating a custom type for each subfield you want to customize. See this issue
