Directly access a form field's value when overriding widget in a twig template

Question

What I want to do is get variables stored in form view.

{% form_theme edit_form _self %}

{% block field_widget %}
{% spaceless %}
{% set type = type|default         


        

Answer 1

You can access the current data of your form via form.vars.value:

{{ form.vars.value.title }}

See Symfony2 Forms documentation: http://symfony.com/doc/current/book/forms.html#rendering-a-form-in-a-template

Dump vars by using dump function:

{{ dump(form.vars.value) }}

If you are using subforms or want to have a value of a specific field:

{{ form.FIELD.vars.VALUE }}

Answer 2

You can access values of the parent parent from a widget block using form.parent.vars

Answer 3

In Symfony > 3 you may use:

form.vars.value.Entity.someValue

Answer 4

Edit2:

Finally, I was indeed getting the value of the current row in {{ value }} here:

{% block field_widget %}
{% spaceless %}
{% set type = type|default('text') %}
<input type="{{ type }}" {{ block('widget_attributes') }} {% if value is not empty %}value="{{ **value** }}" {% endif %}/>

{# MY CODE #}
{% if type == "file" %}
<a class="BOpreview" href="{{ value }}">Aperçu</a>
{% endif %}

{% endspaceless %}
{% endblock field_widget %}

But in my case I get a token instead of the value since I am using input type file. This is due to a security measure in Symfony2.

Answer 5

For example, we want to render the value from a type text field called primerNombre we will need

{{ form.vars.value.primerNombre }}

If we wanted to render the name of one of the children we will need

{% for hijo in form.hijos %}
    <td><div align="left">{{ form_widget(hijo.vars.value.primerNombre) }}</div></td>
{% endfor %}

Good luck!
