Symfony2 form_errors [英] Symfony2 form_errors

问题描述

我认为这是一个简单的问题.它关于输出错误.这是我的树枝文件:

I think its a simple question. Its about outputting errors. This is my twig file:

    <table>
        <tr>
            <td>{{ form_label(form.dueDate) }}</td>
            <td>{{ form_widget(form.dueDate) }}</td>
            <td>{{ form_errors(form.dueDate) }}</td>
        </tr>
        <tr>
            <td>{{ form_label(form.task) }}</td>
            <td>{{ form_widget(form.task) }}</td>
            <td>{{ form_errors(form.task) }}</td>
        </tr>
    </table>

现在每个错误显示(td with form_errors())为:

Now each error displays (td with form_errors()) as:

• 此值不应为空

我的问题是:我想将错误输出为纯文本(没有 ul 和 li).

我知道有一个这样的例子:

I know there is an example like this:

{% for error in errors %}
    {{ error.message }}        
{% endfor %}

但这会一个接一个地输出错误.我想在特定输入处显示它们:

But this will output errors one after another. I want to display them where specific input is:

{{ myErrorFor form.dueDate }}</td>

< td>{{ myErrorFor form.dueDate }}< /td>

非常感谢您的帮助

推荐答案

您可以通过使用 field_errors 块提供自己的表单主题来自定义表单错误的呈现方式.

You can customize how form errors render by providing your own form theme with a field_errors block.

您可以仅对当前模板执行此操作:

You can do this for just the current template:

{# tell the form to look for theme blocks in the current template #}
{% form_theme form _self %}

{% block field_errors %}
{% for error in errors %}
{{ error.messageTemplate|trans(error.messageParameters, 'validators') }}<br>
{% endfor %}
{% endblock %}

{# the rest of your template... #}

或者通过在 config.yml 中定义一个全局表单主题:

Or by defining a global form theme in config.yml:

twig:
    form: { resource: "::form_theme.html.twig" }

在这种情况下，您需要将上面的 field_errors 块移动到 app/Resources/views/form_theme.html.twig 和 form_theme> 标签不再需要.

In this case you would want to move the field_errors block above to app/Resources/views/form_theme.html.twig and the form_theme tag is no longer necessary.
