PhalconPHP：如何在SELECT标记中设置Selected选项(PhalconPHP: How to set a Selected option in SELECT tag)

我想用来自Db的值设置<option> 。 到目前为止，我试过这个但没有工作：

$site_select = new Select('site_id', $this->_sites);

I want to set the <option> with the value coming from Db. So far I tried this but not working:

$site_select = new Select('site_id', $this->_sites);

正如Timothy建议的那样使用数据库列生成选择：

new Select('site_id', Sites::find(), array('using' => array('site_id', 'site_name')));

设置给定选择的选定值：

$site_select->setDefault('YOUR_DB_VALUE');

然而，关于Phalcon形式还有另一个可爱的伎俩。 您可以将数据库实体传递给表单类，您的表单将自动填充。

形成：

class YourFormClass extends Phalcon\Forms\Form { public function initialize($entity = null, $options = null) {

控制器：

$entity = YourModel::findFirst(); $form = new YourFormClass ($entity, $options);

请注意，表单输入名称必须与DB / Model列匹配。

Update

Generating the select using DB columns as Timothy recommended:

new Select('site_id', Sites::find(), array('using' => array('site_id', 'site_name')));

Setting the selected value of the given select:

$site_select->setDefault('YOUR_DB_VALUE');

However there is another lovely trick about Phalcon forms. You could pass your DB entity to the form class and your form will be auto populated.

Form:

class YourFormClass extends Phalcon\Forms\Form { public function initialize($entity = null, $options = null) {

Controller:

$entity = YourModel::findFirst(); $form = new YourFormClass ($entity, $options);

Note that Form input names must match DB/Model columns.
