在Drupal 8中,我不明白如何构建“分层”形式。
我有这个样本表格
...
public function buildForm(array $form, FormStateInterface $form_state) {
$form['description'] = array(
'#type' => 'fieldset',
'#title' => t('Main description'),
);
$form['description']['subfirst'] = array(
'#type' => 'textfield',
'#title' => t('subfirst'),
);
$form['description']['subsecond'] = array(
'#type' => 'textfield',
'#title' => t('subsecond'),
);
$form['content'] = array(
'#type' => 'fieldset',
'#title' => t('Main description'),
);
$form['content']['subfirst'] = array(
'#type' => 'textfield',
'#title' => t('subfirst'),
);
$form['content']['subsecond'] = array(
'#type' => 'textfield',
'#title' => t('subsecond'),
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => 'Submit',
);
return $form;
}
public function submitForm(array &$form, FormStateInterface $form_state) {
dpm($form_state->getValues(),"getValues");
}
...
当我提交表单时,我的form_state-> getValues()会返回:
form_state->getValues()
仅包含['content']['subfirst']
和['content']['subsecond']
值...
这意味着我必须使用api形式的唯一标签?我觉得很奇怪......
然后,我改变了我的形式:
$form['content']['subfirst'] become $form['content']['totosubfirst']
$form['content']['subsecond'] become $form['content']['todosubsecond']
新代码:
public function buildForm(array $form, FormStateInterface $form_state) {
$form['description'] = array(
'#type' => 'fieldset',
'#title' => t('Main description'),
);
$form['description']['subfirst'] = array(
'#type' => 'textfield',
'#title' => t('subfirst'),
);
$form['description']['subsecond'] = array(
'#type' => 'textfield',
'#title' => t('subsecond'),
);
$form['content'] = array(
'#type' => 'fieldset',
'#title' => t('Main description'),
);
$form['content']['totosubfirst'] = array(
'#type' => 'textfield',
'#title' => t('subfirst'),
);
$form['content']['totosubsecond'] = array(
'#type' => 'textfield',
'#title' => t('subsecond'),
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => 'Submit',
);
return $form;
}
当我提交表单时,我的form_state-> getValues()会返回:
我得到了四个值。但是,它们处于同一层级。我如何使用表单api获得这样的form_state:
'description' => 'subfirst' => string(3) "AAA"
'description' => 'subsecond' => string(3) "BBB"
'content' => 'totosubfirst' => string(3) "CCC"
'content' => 'totosubsecond' => string(3) "DDD"
?
我想获得一个分层的form_state,因为我想创建一个自定义函数,如:
foreach element in description
do that
foreach element in content
do that
