在视图Zend Framework 2中获取输入值

Question

I created a form input

$this->add(array( 'name' => 'submit', 'attributes' => array( 'type' => 'submit', 'value' => 'UserRestorePassword.Restore', 'id' => 'submitbutton', 'class' => 'btn btn-primary btn-sm', 'style' => 'padding: 7px 35px;' ), ));

And this generates:

<input name="submit" type="submit" id="submitbutton" class="btn btn-primary btn-sm" style="padding: 7px 35px;" value="Restore">

In view:

 <?=$this->translate($this->formSubmit($form->get('submit')));?>

How to get Restore value from this form?

Answer 1

如果你只想value的属性submit元素，调用getValue该元素的方法

$value = $form->get('submit')->getValue();  // = UserRestorePassword.Restore

Answer 2

from https://stackoverflow.com/a/12367718/468891 :

If you need the value from the form which has been assigned previously, you can access it using

$form->get('elementName')->getValue(); However, if you're using InputFilters, you need to fetch it using

$form->getInputFilter()->getValue('name');

Otherwise, the value you're retrieving was not passed through the filters.
