Validation of a form - I'm getting the labels two times

Question

I have a registration form - from FOSUserBundle this is in the template:

{% form_theme form \'AcmeMyBundle:Form:errors.html.twig\' %}

   


        

Answer 1

# config.yml
# ...
fos_user:
    db_driver:     orm
    firewall_name: main
    user_class:    Acme\YourBundle\Entity\User
    registration:
        form:
            type: acme_user_registration
            validation_groups: [Registration]
# ... 

Adding the last line ("validation_groups: [Registration]") results in only one error. Only FOSUserBundle validation: "Registration".

Ok, this is a known issue.

Let's have a look here : https://github.com/symfony/symfony/issues/2605

The solution is : create your own validation group for properties' validation rules you want to override. In your validation.xml, put only properties you want some different rules, and define validation on a new validation group.

So, for validation.xml, to modify only plainPassword validation rules for your entity (Acme\MyBundle\Entity\User) :

<?xml version="1.0" ?>
<constraint-mapping xmlns="http://symfony.com/schema/dic/constraint-mapping"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/dic/constraint-mapping
http://symfony.com/schema/dic/constraint-mapping/constraint-mapping-1.0.xsd">

    <class name="Acme\MyBundle\Entity\User"> 

        <property name="plainPassword">
            <constraint name="NotBlank">
                <option name="message">fos_user.password.blank</option>
                <option name="groups">Registration</option>
            </constraint>
            <constraint name="Length">
                <option name="min">6</option>
                <option name="minMessage">fos_user.password.short</option>
                <option name="groups">
                    <value>RegistrationAcme</value>
                    <value>ProfileAcme</value>
                </option>
            </constraint>
        </property>
    </class> 

</constraint-mapping>

And now you have to state that you use different validation groups for the impacted forms (registration and profile). Fortunately, FOSUserBundle is a good practices' example and allows you to override them in your config.yml :

fos_user:
    registration:
        form:
            validation_groups: [Default, RegistrationAcme]
    profile:
        form:
            validation_groups: [Default, ProfileAcme]
