symfony2 文本字段自定义标签

发布于 2024-10-30 14:09:53 字数 499 浏览 2 评论 0原文

我在使用 symfony2 Field 组件时遇到了一些但令人不快的问题。例如,我想在树枝模板中输出表单字段数组:

{% for field in form %}
    {{ form_label( field ) }}: {{ form_field( field ) }}
{% endfor %}

这是文本字段配置:

$field = new TextField( 'FieldName', array(
    'label' => 'MyCustomLabel',
) );

但不幸的是,当引擎呈现此输出时,我得到“FieldName”作为标签而不是“MyCustomLabel”。如果我输出的表单字段不在 for 中,我不会有问题(在这种情况下,我可以在模板中为每个字段添加一个标签)。但脚本在执行之前并不知道表单字段的具体数量和配置。所以,我需要实现场渲染的循环方法。我也想保留树枝符号......我会很高兴得到一个好的建议:)

I had a little but unpleasant problem with symfony2 Field component. For example, I would like to output array of form fields in twig template:

{% for field in form %}
    {{ form_label( field ) }}: {{ form_field( field ) }}
{% endfor %}

And here is text field configuration:

$field = new TextField( 'FieldName', array(
    'label' => 'MyCustomLabel',
) );

But unfortunately when engine renders this output i get 'FieldName' as label instead of 'MyCustomLabel'. I would not have problems if i outputting form fields not in for (in that case i can just add a label in template for each field). But the script doesn't know certain quantity and configuration of form fields before execution. So, I need to implement cycle method for field rendering. And I also want to stay in twig notation...I will be pleased for a good advise :)

如果您想更改标签,请按照以下步骤操作。
1)创建表单类。
2) add('fieldName',null,array('label' => 'My New Label:'))

请不要更改 fieldName,但您可以在数组中使用 Label。

享受!

If you want to change the label, than follow the steps.
1) Create form class.
2) add('fieldName',null,array('label' => 'My New Label:'))

please do not change fieldName, but you can play with Label within an array.

Enjoy!

在模板中执行此操作的最简单方法 - 将第二个参数传递给 form_label

<div class="form-group">
    {{ form_label(form.email, 'Email:') }} <- this row
    {{ form_widget(form.email, {'attr': {'class': 'form-control'}}) }}
</div>

The easiest way to do it in template - pass the second argument to the form_label

<div class="form-group">
    {{ form_label(form.email, 'Email:') }} <- this row
    {{ form_widget(form.email, {'attr': {'class': 'form-control'}}) }}
</div>

对于那些偶然发现这个问题并希望得到答案的 Symfony 2.1 用户来说,这几乎就是 @rikinadhyapak 的答案。

如果您在 buildForm 方法中扩展了某些包(如 FOSUserBundle)的 FormType 类:

    $field = $builder->get('username');         // get the field
    $options = $field->getOptions();            // get the options
    $type = $field->getType()->getName();       // get the name of the type
    $options['label'] = "Login Name";           // change the label
    $builder->add('username', $type, $options); // replace the field

An answer for the Symfony 2.1 users who stumble onto this hoping for an answer, it's almost there is the @rikinadhyapak answer.

if you have extended the FormType class of some bundle like FOSUserBundle, in your buildForm method:

    $field = $builder->get('username');         // get the field
    $options = $field->getOptions();            // get the options
    $type = $field->getType()->getName();       // get the name of the type
    $options['label'] = "Login Name";           // change the label
    $builder->add('username', $type, $options); // replace the field

老实说,我会推迟几周学习 Symfony Form 组件。 Symfony 开发人员正在对 Form API 进行重大修改。据我了解,大部分工作已经完成,并且 拉取请求已提交到主存储库< /a>.

I would honestly hold off on learning the Symfony Form component for a couple weeks. Symfony devs are doing a major-overhaul on the Form API. From what I understand, most of it is done, and a pull request has been submitted to the main repository.

对于 Symfony 2.3,您可以使用事件替换标签,如下所示:

$builder->addEventListener(FormEvents::POST_SET_DATA, function (FormEvent $event)
{
    $form = $event->getForm();
    $object = $event->getData();

    $field = $form->get('fieldname');
    $config = $field->getConfig();
    $options = $config->getOptions();
    $options['label'] = 'New label'; // change the label
    $form->add($field->getName(), $config->getType()->getName(), $options); // replace the field

});

但我会避免这种情况。

For Symfony 2.3 you can replace the label using the events as the following:

$builder->addEventListener(FormEvents::POST_SET_DATA, function (FormEvent $event)
{
    $form = $event->getForm();
    $object = $event->getData();

    $field = $form->get('fieldname');
    $config = $field->getConfig();
    $options = $config->getOptions();
    $options['label'] = 'New label'; // change the label
    $form->add($field->getName(), $config->getType()->getName(), $options); // replace the field

});

but I would avoid this.
