问题:

I need to display all errors above the form and display a separate error for each field. How can I do this?

回答1:

You need to be more specific but hopefully the following can help you.

Lets assume you have a variable called form.

{{ form_errors(form) }} Displays global errors not specific to one field

{{ form_errors(form.email) }} Displays errors specific to field

{{ form_row(form.email) }} Displays form_widget form_label and form_errors for field

http://symfony.com/doc/2.0/cookbook/form/form_customization.html

Edit:

So if you want your global and field errors to be displayed in he same place you can do:

{{ form_errors(form) }}
{{ form_errors(form.field1) }}
{{ form_errors(form.field2) }}
...

{% spaceless %}
    {% if not form.vars.valid %}
            <div class="alert alert-error">
                {{ form_errors(form) }}

        {% for children in form.children %}
            {% if not children.vars.valid %}
                {{ form_errors(children) }}

                {# or with field label
                <ul>
                    {% for error in children.vars.errors %}
                        <li><b>{{ children.vars.label }}</b>: {{ error.message }}</li>
                    {% endfor %}
                </ul>
                #}
            {% endif %}
        {% endfor %}
            </div>
    {% endif %}
{% endspaceless %}

I'm overriding form_div_layout.html.twig in my bundle:

{% block form_errors %}
    {% spaceless %}
        {% set a = false %}
        {% for child in form.children  %}
            {% if child.get("errors") %}
                {% set a = 'true' %}
            {% endif %}
        {% endfor %}
        {% if a == true %}
            <div class="alert">
                {% for children in form.children %}
                    {{  form_errors(children) }}
                {% endfor %}
            </div>
        {% endif %}
        {% if errors|length > 0 %}
            <ul>
                {% for error in errors %}
                    {{
                    error.messagePluralization is null
                    ? error.messageTemplate|trans(error.messageParameters, 'validators')
                    : error.messageTemplate|transchoice(error.messagePluralization, error.messageParameters, 'validators')
                    }}
                {% endfor %}
            </ul>
        {% endif %}
    {% endspaceless %}
{% endblock form_errors %}

Now if write form_errors(form) it display all error in form and error over each field also indicates.

回答4:

In Symfony 3.2, to get all form errors in a template, you can use a bit hacky, but simple and working solution using form.vars.errors.form.getErrors(true):

<ul>
    {% for error in formView.vars.errors.form.getErrors(true) %}
    <li>{{ error.message }}</li>
    {% endfor %}
</ul>

The trick is that:

the original form object through the errors iterator (formView.vars.errors.form),
the form.getErrors(true) gives you a recursive iterator over all form errors.

回答5:

Your form aswell as your fields all have seperate error fields to start with. Could you be more specific what you are trying to do and where your problem is?

I revised @korvinko's script, This works for Symfony 2.6.11 `

{% block form_errors %}
    {% spaceless %}
        <ul>
            {% for children in form.children %}
                {% if not children.vars.valid %}
                   {% for error in children.vars.errors %}
                        <li>{{ children.vars.label ~ ' ' ~
                        error.messagePluralization is null
                        ? error.messageTemplate|trans(error.messageParameters, 'validators')
                        : error.messageTemplate|transchoice(error.messagePluralization, error.messageParameters, 'validators')
                        }}</li>
                    {% endfor %}
                {% endif %}
            {% endfor %}
        </ul>

        {% if errors|length > 0 %}
            <ul>
                {% for error in errors %}
                    <li>{{
                    error.messagePluralization is null
                    ? error.messageTemplate|trans(error.messageParameters, 'validators')
                    : error.messageTemplate|transchoice(error.messagePluralization, error.messageParameters, 'validators')
                    }}</li>
                {% endfor %}
            </ul>
        {% endif %}
    {% endspaceless %}
{% endblock form_errors %}
