本文详细讲述了yii实现级联下拉菜单的方法,具体步骤如下:
1.模版中加入如下代码:
<?php echo $form->dropDownList($model, 'src_type_id', OrderSrc::options(), array( <span style="white-space:pre"> </span>'id' => 'task-order-src-id', )); echo $form->dropDownList($model, 'src_shop_id', array(''=>'全部'), array( <span style="white-space:pre"> </span>'id' => 'task-shop-id', )) ?>
在这段代码中,OrderSrc_options() 这个是先读取一个下拉菜单。调用OrderScr model中的options方法。内容如下
public static function options($hasShop = true) { $model = new self(); if($hasShop) $model->hasShop(); $models = $model->findAll(); $array = array(''=>'全部'); foreach($models as $model) { $array[$model->src_id] = $model->src_name; } return $array; }
2.然后在模版页面中增加JS代码,实现当第一个下拉菜单变化时给第二个下拉菜单进行内容赋值。
<script type='text/javascript'> $().ready(function(e) { $('#task-order-src-id').change(function(e) { refreshShops(); }); refreshShops(); function refreshShops() { $.get('<?php echo $this->createUrl('getShops')?>', { 'srcId': $('#task-order-src-id').val() }, function(html_content) { $('#task-shop-id') .html(html_content) .find('option[value=<?php echo $model->src_shop_id?>]') .attr('selected', 'selected'); }); } }); </script>
在这段JS代码中,实现调取一个程序获取第二个下拉菜单的值(调用Controller中的actionGetShops方法),任何追加到第二个下拉菜单中。
Controller中的actionGetShops方法如下:
public function actionGetShops() { $srcId = $_GET['srcId']; $array = ThirdpartInterfaceConfig::options($srcId); $htmlContent = "<option value=''>全部</options>"; foreach($array as $k=>$v) { $htmlContent .= "<option value='{$k}'>{$v}</option>"; } echo $htmlContent; }

The best way to send emails is to use the PHPMailer library. 1) Using the mail() function is simple but unreliable, which may cause emails to enter spam or cannot be delivered. 2) PHPMailer provides better control and reliability, and supports HTML mail, attachments and SMTP authentication. 3) Make sure SMTP settings are configured correctly and encryption (such as STARTTLS or SSL/TLS) is used to enhance security. 4) For large amounts of emails, consider using a mail queue system to optimize performance.

Sending mail using PHP and SMTP can be achieved through the PHPMailer library. 1) Install and configure PHPMailer, 2) Set SMTP server details, 3) Define the email content, 4) Send emails and handle errors. Use this method to ensure the reliability and security of emails.

The reason for using Dependency Injection (DI) is that it promotes loose coupling, testability, and maintainability of the code. 1) Use constructor to inject dependencies, 2) Avoid using service locators, 3) Use dependency injection containers to manage dependencies, 4) Improve testability through injecting dependencies, 5) Avoid over-injection dependencies, 6) Consider the impact of DI on performance.
