I've got a form, with an embed form, and this embed form contains a form collection.
I can customize this collection doing :
{% block _form_refProspect_objects_widget %}
<div class="text_widget">
...
</div>
{% endblock %}
Having my form called form, the embed form called refProspect, and the collection called objects. That works, but what if I want to customize only one field ?
For example, having a field called name, none of thise works :
{% block _form_refProspect_objects_0_name_widget %}
{% block _form_refProspect_objects_name_widget %}
Is there any solution ?
Thanks !
EDIT :
At the same time I would like this customization to work on the form prototype, so I can use javascript to dynamically add some.
you can create your custom field type and add your logic to it.
a pretty good example would be How to Create a Custom Form Field Type
For example i use a custom CKEditor field type to make text fields as WYSIWYG editors. I used this bundle. You could check the source code to see how it works.

Say I have a form named myform with an input field named myinput. By default, symfony will generate HTML widget like:
<input name="myform[myinput]" ... >
This doesn't work with my current javascripts and I need to get the following instead:
<input name="myinput" ...>
I've searched quite a bit and found 2 ways to achieve this:
return null in getBlockPrefix() method in form type class.
create the form using FormFactoryInterface::createNamed() and pass null as name.
It seems like the first method is not recommended, since it would limit the ability to customize form rendering using prefixed blocks.
The 2nd method was recommended here and here.
However both methods will change the name of the form to null and as a result symfony will generate the form like:
<form name="" ...>
This is probably because form_div_layout.html.twig looks like:
<form name="{{ name }}" ...
Which doesn't validate as HTML5.
According to this page, "this is not a bug".
I know I can override the form_start block in the template and remove the name altogether, but it seems that the form wasn't designed to be used with null names in general (hence no check for name length in the template).
So my question is: What is the recommended and HTML5 compatible way to remove input name prefixes for symfony forms?
It was a bug in form rendering. I've submitted a pull request to symfony repo which was accepted.
Until the change is released, a temporary solution would be to add this code to your form theme:
{# fix HTML5 validation of forms with null names #}
{% block form_start %}
{% set name = name|default(block_prefixes.1) %}
{{ parent() }}
{% endblock %}
Regarding PHP, I think either option is OK.
Regarding Twig, I'd go for creating a custom form theme and, optionally, apply it to all forms on the site. I think that's the Symfony way of rendering a form according to your, specific, needs (nullable form name).
I tried to create tags for my Posts as described in doc (tutorial My first website). But i need to show these tags in specific order. Is there some simple way or i just need to create own class with Orderable?
I have assumed you have gotten to this point in the docs - Tagging Posts and want to present the view of your BlogPage with the tags in a special order (eg. alphabetical). Orderable is if you want to do more complex admin interaction with InlinePanels and ordering of related models, where you are asking the page editor to order related items themselves.
The tutorial has this code for your template blog_page.html:
{% if page.tags.all.count %}
<div class="tags">
<h3>Tags</h3>
{% for tag in page.tags.all %}
<button type="button">{{ tag }}</button>
{% endfor %}
</div>
{% endif %}
To work with a custom ordering of your tags, you will need to set up a way to send your ordered tags to the template context. The easiest way to do this is to have a method added to your BlogPage model, we will call this get_ordered_tags.
class BlogPage(Page):
date = models.DateField("Post date")
# other fields...
def get_ordered_tags(self):
"""Specific ordered list of tags."""
# ordered_tags = self.tags.order_by('?') # order randomly
ordered_tags = self.tags.order_by('name') # order by tag name
return ordered_tags
Further up the page you would have seen the docs on Overriding Context, we will do something similar to add ordered_tags to our Page's context.
We can then easily make one minor change to our template, just replace:
{% for tag in page.tags.all %}
With:
{% for tag in page.get_ordered_tags %}
So instead of getting the tags in their default order, we are getting them in our specific order.
Be patient is my first question and my english is also poor ;P
Btw... im using fos for my website and all work fine, actually my problem is that i have the "pages" template made with twig and it have, at the bottom, a call to action button that slideDown an hidden div where i want to put my registration form.
I setup the hidden div and try to put inside my include:
{% block fos_user_content %}
{% include "FOSUserBundle:Registration:register_content.html.twig" %}
{% endblock fos_user_content %}
obviously it dosn't work:
Variable "form" does not exist in kernel.root_dir/Resources/JuliusUserBundle/views/Registration/register_content.html.twig at line 2
probably for some reasons related to routing or firewall or security?
anyone have a solutions, suggestions or ideas for that?
thanks and cheers!
As error said, you need to define 'form' variable in your action, or you could try to render FOSUser registration action instead of this.
For example:
{% render(controller(FOSUserBundle:Registration:register")) %}
If you need to use include then you have to pass the form variable to your included template. Optionally you can render that template also from its corresponding controller.
So for the first case you have:
{% include("FOSUserBundle:Registration:register_content.html.twig") with {'form':form} %}
Where form here is the variable you pass from your own controller. Your second choice would be to render the FOSUB template like so:
{% render(controller("FOSUserBundle:Registration:register")) %}
Apparently i found a good solution using Edge Side Includes (ESI) includes that give me also additional benefits in cache control:
<esi:include src="http://localhost:8004/login" />
I got the solution for keeping the field data when having error here.
But my form fields are in loop so when I use
{{form.varName_ofField}} it does not work.
Please help...
You can only access the form variable within a form object. For example:
{% form 'contact' %}
available here: {{form.email}}
{% endform %}
but not here: {{form.email}}
For rendering form errors in a twig template, you just have to use the form_errors twig macro without difference if it is a global form error or a field error.
But in my case, a global error is not rendered like a field error, so I can't use the form_errors twig macro for the two cases. I decide to use the macro for the field error & I would like to get the global form errors from the Symfony\Component\Form\FormView object. The goal is to iterate the global errors in the twig template & render them like I want.
Actually, I don't find any ressources on the symfony2 documentation which can help me.
Finally, I found the solution by myself. For the people who want to do the same thing, the solution is to call $formView->get("errors") which gives you an array of FormError
I'm using symfony 2.5 and it worked perfect for me in this way.
MyController
$error = new FormError(ErrorMessages::USER_NOT_AUTHENTICATED);
$form->addError($error);
MyView
{% for error in form.vars.errors %}
<div class="alert alert-danger" role="alert">
{{ error.messageTemplate|trans(error.messageParameters, 'validators')~'' }}
</div>
{% endfor %}
hope this will save someones time.
in symfony 2.3 all accessor methods have been removed in favor of public properties to increase performance.
$formView->get("errors");
is now:
$formView->vars["errors"];
