如何获取所选选项的名称并将其发送到其他PHP脚本？

Question

This is my jQuery code

<script>
$(document).ready(function() {
   $('#countries').change(function(){
      $('#countriesForm').submit();
   });
});
</script>

and my php code looks like this

<form action="<?php echo $this->createUrl($this->id."/".$this->action->id); ?>" id="countriesForm" method='POST'>
<?php echo CHtml::dropDownList('countries', $select = array(),
 CHtml::listData($countries, 'code', 'name'));
?>
<form>
<div class='description'></div>

Can someone pls help me how to get echo/print name or code of the selected country into the div .description. And how to send the selected code to other php script.

Answer 1

It can be like

<div class='description'><?php
if( isset($_POST['countries']) ) {
    echo CHtml::encode($_POST['countries']);
}
?></div>
