[Form] error_bubbling: Option to show the error message twice, i.e. at the field and (bubbled) at the form

[ThomasLandauer]

Description
On longer forms it's a good idea to show validation errors twice: as a complete summary on top of the form, plus on each invalid field. Right now, by either setting error_bubbling to true or false, you can only have one of these options, but not both: https://symfony.com/doc/current/reference/forms/types/form.html#error-bubbling

Possible implementation: At #9994 an option error_location (or display_errors) was discussed, with possible values self | parent | root. If the value would be an array (instead of a string), you could opt for multiple locations.

That would be really great. I don't understand that this is not something requested often before.

Anyone eager to give it a try?

[MichaelBrauner]

I solved it by creating a {{ block('form_has_errors_message') }} inside my {%- block form_start -%}:

{% block form_has_errors_message %}
    {% if not form.vars.valid %}
        <div class="alert alert-error">
            {{ 'Your form could not be sent. Below you can see the errors that occurred.'|trans }}
        </div>
    {% endif %}
{% endblock %}

That does the trick for me. I don't want to print all the error messages twice anyway.

Thank you for this suggestion.
There has not been a lot of activity here for a while. Would you still like to see this feature?

[MichaelBrauner]

I mean it would be nice! But since there is an easy workaround - I guess there may be other more important things to solve/do.

I am closing here as it seems that nobody cared enough to give this an actual try. Thanks for proposing.

I'm now doing it right inside my template below {{ form_start() }} like this:

{% for child in form.children %}
    {% if child.vars.errors is defined %}
        {% for error in child.vars.errors %}
            <div class="some-errorr">{{ error.message }}</div>
        {%- endfor -%}
    {% endif %}
{% endfor %}
