{% form_theme form _self %}
{% block collection_entry_row %}
{% set fields = form.attributes.children[0].children %}
{% for key, field in fields %}
{{ form_widget(field) }}
{{ form_widget(fields[key]) }}
{% endfor %}
{% endblock %}
And I get this error:
Neither the property "attributes" nor one of the methods "attributes()", "getattributes()"/"isattributes()"/"hasattributes()" or "__call()" exist and have public access in class "Symfony\Component\Form\FormView".
But this
{% set fields = form.attributes.children[0] %}
{% for key, field in fields %}
{{ dump(field) }}
{% endfor %}
Produces this:
Symfony\Component\Form\FormView {#2150 ▼
+vars: array:33 [▶]
+parent: Symfony\Component\Form\FormView {#2203 ▶}
+children: []
-rendered: false
-methodRendered: false
}
And yet inside the form_start() I can do the following and render one field at a time:
{% set tempInput = form.children['attributes'].children[0].children['attributes'].children[0].children['pin'] %}
{{ form_widget(tempInput) }}
Thoughts?
just had the same questions as you about this subject, and since i didn't understands the way to use the "{% block collection_row %}" i've found this following workaround.
I find out that the problem i had was coming from the 2 last item of the form.children: "submit" and "_token".
Because, of course, they will not have the variable name you are searching in the other "real" forms childs.
So i just added a check to the length of the children array to exclude this "submit" and "_token" items.
(The test might certainly be different for your case).
{% for child in form.children %}
{% if not child.children | length != 4 %} // my array has 4 items, submit and _token have none
{{ form_widget(child.children.variableName) }}
{% endif %}
{% endfor %}
As you can see you can access your collection variable between the if like this:
{{ form_widget(child.children.variableName) }}
Peace.

My list and show fields contain the same content, but due the extending of base_list_field and base_show_field templates I have to create two separate templates.
list/location.html.twig:
{% extends 'SonataAdminBundle:CRUD:base_list_field.html.twig' %}
{% block field %}
{{ object.getCity }}, {{ object.getCountry.getName }}
{% endblock %}
show/location.html.twig:
{% extends 'SonataAdminBundle:CRUD:base_show_field.html.twig' %}
{% block field %}
{{ object.getCity }}, {{ object.getCountry.getName }}
{% endblock %}
As you can see huge part of code is duplicated. Is there a way to check the page I am currently in in twig and then extend certain base template? In this case I would be able to use one file instead of two for same content.
In twig it's possible to extend/include a dynamic template :
{# do test here on which page you are or pass through controller #}
{% if true %}
{% set template = 'SonataAdminBundle:CRUD:base_show_field.html.twig' %}
{% else %}
{% set template = 'SonataAdminBundle:CRUD:base_list_field.html.twig' %
{% endif %}
{% extends template %}
{% block field %}
{{ object.getCity }}, {{ object.getCountry.getName }}
{% endblock %}
(edit) if you don't want the hardcoded if I would pass the template variable through the controller and change the twig template to something like
{% extends template|default('SonataAdminBundle:CRUD:base_show_field.html.twig') %}
First of all I'm learning Twig.
I was wondering if it is possible wit Twig to compare two different values from different arrays/lists?!
I have two list of items I call them like so:
{% if page.cart %}
{% for product in page.cart.products %}
{{ product.id }}
{% endfor %}
{% endif %}
And:
{% if products %}
{% for product in products %}
{{ product.id }}
{% endfor %}
{% endif %}
I want to compare both product.id's so I can create a new statement. Is there any way to compare both values? The idea is to check if an id is present in page.cart.products and if so then do something.
I want to create a new statement to display some info. Something like so:
{% if page.cart %}
{% for product in page.cart.products %}
{% set cartId %}{{ product.id }}{% endset %}
{% endfor %}
{% endif %}
{% if products %}
{% for product in products %}
{% set listId %}{{ product.id }}{% endset %}
{% endfor %}
{% endif %}
{% if cartId == listId %}
.... do this ....
{% endif %}
Any help greatly appreciated!
You can loop over one array and check if the id is present in the second one. If it's there, you can do something.
{# In case you want to store them, you can do so in an array #}
{% set repeatedIds = [] %}
{% for productCart in page.cart.products if page.cart %}
{% for product in products if products %}
{% if productCart.id == product.id %}
<p>This id -> {{ product.id }} is already in page.cart.products</p>
{% set repeatedIds = repeatedIds|merge([product.id]) %}
{% endif %}
{% endfor %}
{% endfor %}
{{ dump(repeatedIds) }}
It's a very basic search algorithm and the cost is quadratic. Obviously, there are more efficient ways to look for an element in an array (though more complicated to implement).
If the amount of products you have to deal with is not very big, you could use this solution. However, if you have, let's say, more than one hundred products in each array (or you feel that the algorithm is slowing down your loading time), you could do this process in the controller using more sophisticated methods and PHP and just pass the result to the template.
Hope it helps.
I have an object called "template.Highlights" where exists 7 items. All items have 2 fields: 'name','desc'. How can I access (without multiples if's) an item through the value of the 'name' field? (the names are: 'hl1', 'hl2', 'hl3', 'hl4', 'hl5', 'hl6', 'hl7').
{% for template.Highlights as highlight %}
{% if highlight.name == 'hl5' %}
{% set item = highlight %}
{% endif %}
{% endfor %}
{{ item.name }}, {{ item.desc }}
I'd like to create a custom template in twig to render a form field.
Example:
{{ form_row(form.field) }}
This can be overriden by form theming
{% block form_row %}
... custom code
{% endblock form_row %}
What I would like to do is this:
{% block custom_row %}
... custom code
{% endblock custom_row %}
and use it like this:
{{ custom_row(form.field }}
however, this throws an exception that method custom_row is not found.
My understanding is that this can be done with Twig extension, but I don't know how to register a block to be a function.
Update
what I actually want:
I use twitter bootstrap and a bundle which overrides all the form themes. And it renders a div around a radio, so it can't be inlined. So I wanted to do something like this:
copy their template and get rid of the div:
{% block inline_radio_row %}
{% spaceless %}
{% set col_size = col_size|default(bootstrap_get_col_size()) %}
{% if attr.label_col is defined and attr.label_col is not empty %}
{% set label_col = attr.label_col %}
{% endif %}
{% if attr.widget_col is defined and attr.widget_col is not empty %}
{% set widget_col = attr.widget_col %}
{% endif %}
{% if attr.col_size is defined and attr.col_size is not empty %}
{% set col_size = attr.col_size %}
{% endif %}
{% if label is not sameas(false) %}
{% if not compound %}
{% set label_attr = label_attr|merge({'for': id}) %}
{% endif %}
{% if required %}
{% set label_attr = label_attr|merge({'class': (label_attr.class|default('') ~ ' required')|trim}) %}
{% endif %}
{% if label is empty %}
{% set label = name|humanize %}
{% endif %}
{% set label_attr = label_attr|merge({'class': (label_attr.class|default('') ~ ' radio-inline')|trim}) %}
<label{% for attrname, attrvalue in label_attr %} {{ attrname }}="{{ attrvalue }}"{% endfor %}>
{{ block('radio_widget') }}
{{ label|trans({}, translation_domain) }}
</label>
{% else %}
{{ block('radio_widget') }}
{% endif %}
{{ form_errors(form) }}
{% endspaceless %}
{% endblock inline_radio_row %}
and then
{{ inline_radio_row(form.field) }}
I ended up just overriding the whole theme, and added ifs around the div in question, a the class (radio-inline). But I'm still wondering if there's a way to make this work. Seems like it makes you work so hard for something so simple.
Update 2
I found the functionality:
class FormExtension extends \Twig_Extension
{
public function getFunctions()
{
return array(
'inline_radio_row' => new \Twig_Function_Node(
'Symfony\Bridge\Twig\Node\SearchAndRenderBlockNode',
array('is_safe' => array('html'))
),
);
}
}
This does exactly what I want, but it says it's deprecated. Anyone knows an updated version of how to use this?
Update 3
Similar functionality can be also achieved with http://twig.sensiolabs.org/doc/tags/include.html
You can use the twig functions for each part of a form row:
form_label(form.field)
form_widget(form.field)
form_errors(form.field)
For example:
<div class="form_row">
{{ form_label(form.field) }} {# the name of the field #}
{{ form_errors(form.field) }} {# the field #}
{{ form_widget(form.field) }} {# the errors associated to the field #}
</div>
You can use form theming.
Step by step:
1. Form Type Class
Check the name in your class
public function getName() {
return 'hrQuestionResponse';
}
2. Include a custom theme in your template
{% form_theme form 'InterlatedCamsBundle:Form:fields.html.twig' %}
3. Find the block
Can be quite difficult. For the bootstrap bundle, as you seem to have found it is in ./vendor/braincrafted/bootstrap-bundle/Braincrafted/Bundle/BootstrapBundle/Resources/views/Form/bootstrap.html.twig and you have found the block radio_row. I have been finding the block by putting output in the source template and overriding more blocks than I need. In 2.7 there is a theme 'rendering call graph'.
4. Override the block
Copy the block from the master template and call it replace the standard term with the name of in the FormType found in step 1.
Don't forget to also change the endblock name.
e.g.
{% block hrQuestionResponse_widget %}
hrQuestionResponse_row
{% spaceless %}
{% set class = '' %}
...
{% endspaceless %}
{% endblock hrQuestionResponse_widget %}
In your case because you can only call form_widget() you will need to override _widget. You could extract only the content that you need, or you can override the block chain to radio_row.
Just applying a theme to form field is easy e.g.:
{% form_theme form _self %}
{% block _product_name_widget %}
{{ block('field_widget') }}
{% endblock %}
but what if the form field is of collection type? E.g.: product['models'][1][comment,
I have no ideas how to customize it. (This may be the first kind question here)
UPDATE: anwser here: Symfony2: collection form field type with data-prototype
As of Symfony 2.1 (it may work as well for 2.0 but not sure) to apply theme for collection you do this way:
Lets say we have a collection of products (we have multiple Product entities)
Controller:
$repository = $this->getDoctrine()->getRepository('ExampleBundle:Product');
$products = $repository->findAll();
$productCollection = new Products;
foreach ($products as $product) {
$productCollection->getProducts()->add($product);
}
$collection = $this->createForm(new ProductsType, $productCollection);
return $this->render('ExampleBundle:Default:index.html.twig', array(
'collection' => $collection->createView()
));
Your theme can look like this:
{% block _productsType_products_entry_name_row %}
<div class="yourDivName">{{ block('form_widget') }}</div>
{% endblock %}
{% block _productsType_products_entry_description_row %}
<div class="yourDivDescription">{{ block('form_widget') }}</div>
{% endblock %}
The trick is with "entry" where twig will do the job for you to apply above changes to each row and for each field you specify
Hope that helps!
You can do with override collection_widget block:
{% block collection_widget %}
{% spaceless %}
{% if prototype is defined %}
{% set attr = attr|merge({'data-prototype': form_row(prototype) }) %}
{% endif %}
{{ block('form_widget') }}
{% endspaceless %}
{% endblock collection_widget %}
If you want how to customize form collection type try to look at this Product Bundle
You can override the collection_widget theme for a single field by referencing the widget like this as well.
For example, if "categories" is a "collection" widget on a ProductType form, you can do this.
{% block _product_categories_widget %}
{% for child in form %}
{{- form_row(child) -}}
<hr>
{% endfor %}
{% endblock %}
