Symfony2 form validation - how display only first error message per field

Question

I have a field with sets of validation rules:

/**
 * @var integer
 *
 * @ORM\Column(name="options", type="integer")
 * @Assert\NotBlank()
 * @Assert\Min(limit = "1381", message = "Please provide number higher than 1381")
 * @Assert\Regex(pattern = "/^\d{4}$/" , message = "Four digits are expected")
 */
private $options;

and it seems sometimes Symfony is checking every assertion(what is good) and render every error in view(what is not expected). After submitting a form with option=5 I got folowed error messages in view.

Options
- Please provide number higher than 1381
- Four digits are expected

but when I send option = null then only one error message is displayed.

Options
- This value should not be blank.

Is there a 'switch' which causes that only one error message is rendered in template? I would like to have only one error message per field in my forms.

Patt thanks for pointing me there

A great way to do it would be to use validation sequencing as recommended by symfony form guru @Bernhard :) — Mick

One option is to modify the template/block for a form error block application wide (so that every one of your forms in a template will get the desired behaviour). Or override the form layout on a per template basis.

If you go and look at the default form layout that ships with the Symfony standard edition you can see on line 273 the form_errors twig block is defined.

You could override this block in a given template (as per the documentation), to only echo one element from the errors array:

{# SomeTemplate:Default:index.html.twig #}
{% extends '::base.html.twig' %}

{% form_theme form _self %}

{% block form_errors %}
{% spaceless %}
    {% if errors|length > 0 %}
    {{ errors[0].message }}
    {% endif %}
{% endspaceless %}
{% endblock form_errors %}

{% block content %}
    {# ... render the form #}

    {{ form_rest(form) }}
{% endblock %}

errors|length will be always 1 if error available or 0 if not. So even you have 2 errors (2 fields with errors) - you will get for field {{ id }} always count == 1. My proposition is to use JS and hide more than 1 errors
