forms - form_widget不显示invalid_message错误

Question

当我尝试将render an error message关联到repeated password field时遇到了一个问题。问题是，如果我按以下方式实现 Twig ，则invalid_message不会被渲染，

     {{ form_start(form, {'attr': {'class': 'form-horizontal', 'role': 'form', 'novalidate': 'novalidate'}}) }}
        <div class="form-group {% if form.password.vars.errors|length > 0 %}has-error{% endif %} {% if form.password.vars.required == 'true' %}required{% endif %}">
          {{ form_label(form.password.first, "Password") }}
          <div class="col-sm-8">
            {{ form_widget(form.password.first) }}   
            <span class="help-block">{{ form_errors(form.password) }}</span>
          </div>              
        </div>

        <div class="form-group {% if form.password.vars.errors|length > 0 %}has-error{% endif %} {% if form.password.vars.required == 'true' %}required{% endif %}">
          {{ form_label(form.password.second, "Confirm password") }}
          <div class="col-sm-8">
            {{ form_row(form.password.second) }}

          </div>
        </div>
        ........

但是，如果我使用 form_row，

     {{ form_start(form, {'attr': {'class': 'form-horizontal', 'role': 'form', 'novalidate': 'novalidate'}}) }}
        <div class="form-group {% if form.password.vars.errors|length > 0 %}has-error{% endif %} {% if form.password.vars.required == 'true' %}required{% endif %}">
          {{ form_label(form.password.first, "Password") }}
          <div class="col-sm-8">
            {{ form_row(form.password.first) }}   
            <span class="help-block">{{ form_errors(form.password) }}</span>
          </div>              
        </div>

        <div class="form-group {% if form.password.vars.errors|length > 0 %}has-error{% endif %} {% if form.password.vars.required == 'true' %}required{% endif %}">
          {{ form_label(form.password.second, "Confirm password") }}
          <div class="col-sm-8">
            {{ form_row(form.password.second) }}

          </div>
        </div>
        ........

该错误显示在密码文本框的顶部(这不是我放置该错误的区域，因为 span实际上在文本框下方)，并且也未突出显示该文本框。我尽力解决了这个问题，但是没有运气。如果您的专家可以提供任何专家指导来解决此问题，我将非常感谢。 :)

$builder->add( 'password', 'repeated', array( 'type' => 'password', 
                                      'required' => true,
                                      'invalid_message' => ErrorMessages::PASSWORDS_DONOT_MATCH,
                                      'options' => array('attr' => array('class' => 'password-field form-control')),                                                                                   
                                      'first_options'  => array('label' => false,                                                                    
                                                                'label_attr'=>array('class'=>'col-sm-3 control-label')),
                                      'second_options' => array('label' => false,                                                                    
                                                                'label_attr'=>array('class'=>'col-sm-3 control-label')))); 

Answer 1

解决方案很简单，因此会发布此消息，以防将来有人遇到此问题。解决方案是使用forms_row渲染字段，例如:{{ form_row(form.password.first) }}，并将'error_bubbling' => true包括到要显示错误的字段中。包括此问题解决了字段突出显示和错误消息放置的问题，在我的情况下，我在first password text box下显示了错误。

工作示例

twig

 {{ form_start(form, {'attr': {'class': 'form-horizontal', 'role': 'form', 'novalidate': 'novalidate'}}) }}
    <div class="form-group {% if form.password.vars.errors|length > 0 %}has-error{% endif %} {% if form.password.vars.required == 'true' %}required{% endif %}">
      {{ form_label(form.password.first, "Password") }}
      <div class="col-sm-8">
        {{ form_row(form.password.first) }}   
        <span class="help-block">{{ form_errors(form.password) }}</span>
      </div>              
    </div>

    <div class="form-group {% if form.password.vars.errors|length > 0 %}has-error{% endif %} {% if form.password.vars.required == 'true' %}required{% endif %}">
      {{ form_label(form.password.second, "Confirm password") }}
      <div class="col-sm-8">
        {{ form_row(form.password.second) }}

      </div>
    </div>
    ........

form Controller

$builder->add( 'password', 'repeated', array( 'type' => 'password', 
                                      'required' => true,
                                      'invalid_message' => ErrorMessages::PASSWORDS_DONOT_MATCH,
                                      'options' => array('attr' => array('class' => 'password-field form-control')),                                                                                   
                                      'first_options'  => array('label' => false, 
                                                                //here I enable error bubbling so that on the twig it will render the error under the first password text field 
                                                                'error_bubbling' => true,
                                                                'label_attr'=>array('class'=>'col-sm-3 control-label')),
                                      'second_options' => array('label' => false,                                                                    
                                                                'label_attr'=>array('class'=>'col-sm-3 control-label'))));
