class AdminAction extends Action {
private $uid_t;
public function addassets(){
$uid = I('id');
$this->uid = $uid;
$this->setuid_t($uid);
$this->display();
}
public function setuid_t($uid){
$this->uid_t = $uid;
}
public function getuid_t(){
return $this->$uid_t;
}
public function actaddassets(){
$data['uid'] = $this->getuid_t();
$data['assets_name'] = I('assets_name');
if ($id=M('device')->add($data)) {
$this->redirect('index');
}else{
echo M('device')->getLastsql();exit;
$this->redirect('addassets');
}
}
在addassets()中从前端获得了一个变量id,保存在本地的uid,然后display出addassets.html页面。但是这个页面中不用uid这个变量,而下一个页面(addassets.html中有一个button跳转到actaddassets.html)actaddassets.html中需要用到uid这个变量。通过上面的方法在actaddassets()中获得不了uid这个变量。
初次学习,还往大神指点,谢谢!

class AdminAction extends Action {
static $uid_t="";
public function addassets(){
$uid = I('id');
$this->uid = $uid;
self::$uid_t = $uid;
$this->display();
//echo self::$uid_t;
}
public function actaddassets(){
echo self::$uid_t;
/*

}
做了一些尝试,定义一个static的$uid_t,然后在addassets()中不输出页面,直接echo self::$uid_t是有值的,但是紧接着在actaddassets()中再次echo self::$uid_t就没值了。。求教这是为什么。。?谢谢!
