基本上这只是一个猜谜游戏，这样我就可以了解蛋糕的来龙去路了。我试图跟踪每次页面重新加载时用户猜测的次数(使用变量名$user_loop)。当我尝试增加它时，它保持静态或只增加1并停止。我在视图中放置了增量代码片段，以便只接收相同的结果。任何帮助都太好了。
<?php
class GuessController extends AppController {
public $uses = array();
function beforeFilter() {
if (!$this->Session->check('Random.Num')) {
$this->Session->write('Random.Num', rand(1, 9));
}
}
function create() {
if ($this->request->is('post', 'put')) {
$rn = $this->Session->read('Random.Num');
$user_guess = $this->request->data['Guess']['guess'];
$this->set('user_guess', $user_guess);
$user_loop++ // <- Also getting undefined variable here
echo $user_loop; //for testing
if ($rn == $user_guess) {
echo 'Cashe Cleared';
$this->Session->delete('Random');
}
}
}
}
?>
试试这个:
<?php
class GuessController extends AppController {
public $uses = array();
function beforeFilter() {
if (!$this->Session->check('Random.Num')) {
$this->Session->write('Random.Num', rand(1, 9));
}
if(!$this->Session->check('user_loop')) {
$this->Session->write('user_loop',0);
}
}
function create() {
if ($this->request->is('post', 'put')) {
$rn = $this->Session->read('Random.Num');
$user_guess = $this->request->data['Guess']['guess'];
$this->set('user_guess', $user_guess);
$user_loop = $this->Session->read('user_loop')+1;
echo $user_loop; //for testing
$this->Session->write('user_loop',$user_loop);
if ($rn == $user_guess) {
echo 'Cash Cleared';
$this->Session->delete('Random');
}
}
}
}
?>
