我正在學習如何在Drupal 8
中創建自定義模塊。我被困在創建模塊塊的默認配置。Drupal 8:自定義模塊塊默認配置不起作用
我的模塊的名稱是hello
。根據需要,我創建了一個文件hello/config/install/hello.settings.yml
。然後根據需要,我還在我的HelloBlock
類中創建了defaultConfiguration()
方法。
我嘗試刪除模塊,重新安裝它,並試圖清除緩存。不過,我仍然安裝模塊並放置塊之後,它只是說的Hello !
代替Hello, Batman!
下面是所需的代碼 -
你好/配置/安裝/ hello.settings.yml
hello:
name: 'Batman'
你好\ SRC \插件\塊\ HelloBlock.php
這裏是defaultConfigurtion()函數 -
public function defaultConfiguration() {
$default_config=\Drupal::config('hello.settings');
return array(
'name'=>$default_config->get('hello.name'),
);
}
這裏是整個HelloBlock類 -
class HelloBlock extends BlockBase implements BlockPluginInterface {
/**
* {@inheritdoc}
*/
public function defaultConfiguration() {
$default_config=\Drupal::config('hello.settings');
return array(
'name'=>$default_config->get('hello.name'),
);
}
//Submit the form and save the form value into block configuration
public function blockSubmit($form, FormStateInterface $form_state) {
parent::blockSubmit($form,$form_state);
$values=$form_state->getValues();
$this->configuration['hello_block_name'] =
$values['hello_block_name'];
}
//Add the form
public function blockForm($form, FormStateInterface $form_state) {
$form = parent::blockForm($form,$form_state);
$config = $this->getConfiguration();
$form['hello_block_name'] = array(
'#type'=> 'textfield',
'#title'=> 'Who',
'#description'=>$this->t('Who do you want to say hello to?'),
'#default_value'=>isset($config['hello_block_name'])?
$config['hello_block_name'] : ' ',
);
return $form;
}
//Build the module i.e. Control the view of block
public function build() {
$config = $this->getConfiguration();
if (!empty($config['hello_block_name'])) {
$name = $config['hello_block_name'];
}
else {
$name = $this->t('to no one');
}
return array(
'#markup' => $this->t('Hello @name!', array (
'@name' => $name,
)),
);
}
}
