如何将字符实体放入ZF2中的formSubmit的值中 [英] How to put a character entity in the value of a formSubmit in ZF2

问题描述

当我像这样在ZF2表单中创建一个提交按钮时:

When I create a submit button in a ZF2 form like this:

    $this->add(array(
            'name' => 'save_closebutton',
            'attributes' => array(
                    'type'  => 'submit',
                    'value' => 'Save & Move On »',
                    'id'    => 'save_closebutton',
                    'class' => 'btn btn-default'
            ),
    ));

，然后在这样的视图中放置一个formSubmit元素:

and then put a formSubmit element in the view like this:

    echo $this->formSubmit($form->get('save_closebutton'));

ZF2将按钮中的文本呈现为Save & Move On »，而不呈现代码表示的字符.

ZF2 renders the text in the button as Save & Move On » without rendering the character that the code represents.

我非常确定问题出在formSubmit助手中，因为检查该元素表明该助手创建了该子控件:

I'm pretty sure that the problem is in the formSubmit helper, because inspecting the element shows that the helper creates this:

    <input id="save_closebutton" class="btn btn-default" type="submit" value="Save & Move On &#187;" name="save_closebutton">

但是如果我只是在视图中回显相同的字符串，

but if I simply echo the same string in the view,

    echo '<input id="save_closebutton" class="btn btn-default" type="submit" value="Save & Move On &#187;" name="save_closebutton">';

按钮显示正确.

如何获取formSubmit传递字符而不是代码?

How do I get formSubmit to pass the character and not the code?

推荐答案

FormSubmit帮助器在输出之前转义属性名称和值，AFAIK无法在不提供自定义帮助器的情况下禁用它.

The FormSubmit helper escapes attribute names and values before output, AFAIK there's no way to disable that without providing custom helpers.

由于您的Submit元素只是一个按钮，因此可以使用Button元素和FormButton视图助手来解决您的问题.元素具有标签选项，可让您禁用标签上的html转义，并且助手会尊重该设置.

Since your submit element is just a button, you can use the Button element and the FormButton view helper to solve your problem. The element has a label option which allows you to disable html escaping on the label, and the helper respects that setting.

在表单中创建您的提交按钮...

Create your submit button in the form ...

$this->add(array(
        'name' => 'save_closebutton',
        'type' => 'Button', // \Zend\Form\Element\Button
        'options' => array(
             'label' => 'Save & Move On »',
             // inform the FormButton helper that it shouldn't escape the label
             'label_options' => array(
                  'disable_html_escape' => true,
             ),
        ),
        'attributes' => array(
            'type'  => 'submit',  // <button type="submit" .../>
            'id'    => 'save_closebutton',
            'class' => 'btn btn-default'
        ),
));

使用FormButton助手来渲染元素...

Use the FormButton helper to render the element ...

 echo $this->formButton($form->get('save_closebutton'));
