有人可以请把这个英文给我PHP PHP CakePHP
我很抱歉成为这样一个愚蠢的屁股。 我正在学习一个教程,将管理路由添加到我试图创建的cakephp应用程序中作为学习练习。
该教程没有得到很好的解释(我认为我实际上只是一个初学者太多),我不明白以下内容,请问任何人都可以用英文告诉我这里发生了什么。
public function isAuthorized() {
$role = $this->Auth->user('role');
$neededRole = null;
$prefix = !empty($this->params['prefix']) ? $this->params['prefix'] : null;
if (!empty($prefix) && in_array($prefix, Configure::read('Routing.prefixes'))) {
$neededRole = $prefix;
}
return (empty($neededRole) || strcasecmp($role, 'admin') == 0 || strcasecmp($role, $neededRole) == 0);
}
你有什么问题?
你可以一一调试
// This method provides information of role about the currently authenticated user.
$role = $this->Auth->user('role');
// you first check with var_dump($this->params['prefix']) and see the result
/*
* this line use ternary operator, its say $this->params['prefix'] is not empty
* then set $prefix = $this->params['prefix'] otherwise set $prefix=null
*/
$prefix = !empty($this->params['prefix']) ? $this->params['prefix'] : null;
/*
*Now check the array
*echo "<pre>";
* print_r(Configure::read('Routing.prefixes'));
* echo "</pre>";
* now below line said if `$prefix` is not empty then search that `$prefix`
* value in this array `Configure::read('Routing.prefixes')` and if it
* exist in the array then set `$neededRole = $prefix;
*/
if (!empty($prefix) && in_array($prefix, Configure::read('Routing.prefixes'))) {
$neededRole = $prefix;
}
/* below line say say that if $role == admin then return $role or return $neededRole */
return (empty($neededRole) || strcasecmp($role, 'admin') == 0 || strcasecmp($role, $neededRole)
参考
in_array
三元运算符
乐于帮助 :)
public function isAuthorized() {
//获取当前用户的角色(admin,user,editor,visitor等)。
$ role = $ this-> Auth-> user('role');
//分配一个空值
$ neededRole = null;
//获取前缀的参数并分配给$前缀,如果未找到,则分配null
$ prefix =!empty($ this-> params ['prefix'])? $ this-> params ['prefix']:null;
//如果$ prefix不为空&如果$ prefix有路由,则将$ prefix分配给$ neededRole
if(!empty($ prefix)&& in_array($ prefix,Configure :: read('Routing.prefixes'))){$ neededRole = $ prefix;
} return(empty($ neededRole)|| strcasecmp($ role,'admin')== 0 || strcasecmp($ role,$ neededRole)== 0); }
//剩下的我不太确定..
