Link in form label using route - symfony

Question

In my registration form i have a checkbox "I accept the terms", and want to link the word "terms" to my terms page.
Is there a way to add a link to a form label, using a route? (preferably without injecting the container in the form)

Answer 1

As the solution above somehow didn't work for me I solved it using the solution suggested here: https://gist.github.com/marijn/4137467
OK, so here i how I did it:
{% set terms_link %}<a title="{% trans %}Read the General Terms and Conditions{% endtrans %}" href="{{ path('get_general_terms_and_conditions') }}">{% trans %}General Terms and Conditions{% endtrans %}</a>{% endset %}
{% set general_terms_and_conditions %}{{ 'I have read and accept the %general_terms_and_conditions%.'|trans({ '%general_terms_and_conditions%': terms_link })|raw }}{% endset %}
<div>
{{ form_errors(form.acceptGeneralTermsAndConditions) }}
{{ form_widget(form.acceptGeneralTermsAndConditions) }}
<label for="{{ form.acceptGeneralTermsAndConditions.vars.id }}">{{ general_terms_and_conditions|raw }}</label>
</div>

The best way is to overwrite the twig block used to render that specific label.
First, check the form fragment naming section of the docs. Then create a new block in your form template with the the appropriate name. Don't forget to tell twig to use it:
{% form_theme form _self %}
For the next step check the default form_label block.
You'll probably only need a portion of it, something like this (I'm leaving the default block name here):
{% block form_label %}
{% spaceless %}
<label{% for attrname, attrvalue in label_attr %} {{ attrname }}="{{ attrvalue }}"{% endfor %}>
{{ label|trans({}, translation_domain) }}
</label>
{% endspaceless %}
{% endblock %}

As an option, you can do so:
->add('approve', CheckboxType::class, [
'label' => 'Text part without link',
'help' => 'And download it',
'help_html' => true,
])

In Symfony 5.1 there are new form improvements.
HTML contents are allowed in form labels!
HTML contents are escaped by default in form labels for security reasons. The new label_html boolean option allows a form field to include HTML contents in their labels, which is useful to display icons inside buttons, links and some formatting in checkbox/radiobutton labels, etc.
// src/Form/Type/TaskType.php
namespace App\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\Extension\Core\Type\SubmitType;
use Symfony\Component\Form\FormBuilderInterface;
class TaskType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
// ...
->add('save', SubmitType::class, [
'label' => ' Save',
'label_html' => true,
])
;
}
}
In your case you can set form label directly from template and pass the route there.
{{ form_widget(form.acceptTermsAndConditions, {
label: '' ~ "I accept ..."|trans ~ '',
label_html: true
})
}}

My solution was another:
form:
$builder
->add(
'agree_to_rules',
'checkbox',
[
'required' => true,
'label' => 'i_agree_to'
]
);
And html:
<span style="display:inline-block">
{{ form_widget(form.agree_to_rules) }}
</span>
<span style="display:inline-block">
rules
</span>
And looks the same :)

A very simple way to do it would be
{{ form_widget(form.terms, { 'label': 'I accept the terms and conditions' }) }}
You can also do this if you want to use translation
In your translation file for example messages.en.yml add
terms:
url: 'I accept the terms and conditions'
And in your view add
{{ form_widget(form.terms, { 'label': 'terms.url'|trans({'%url%': path('route_to_terms')}) }) }}
