PHPCMS不显示无权限栏目对应的左侧菜单

PHPCMS可以给某些角色设定权限,比如某些栏目对于某些角色是无法访问的。但是左侧菜单还是会显示该栏目名称,这对编辑来说是不需要的。都访问不了,还显示栏目名称干啥呢。看了一下PHPCMS的代码,简单地实现了隐藏菜单的小功能。

从后台页面可以很简单地分析出,左侧菜单的生成是用Ajax:

$.ajax(
{	
	type:'get', 
	url:'?mod=phpcms&file=menu&action=get_menu_list&menuid='+id, 
	cache:cache_refresh,
	dataType:'json', 
	success:function(json)
	{
		……
	}
}

请求的地址是 http://www.bkjia.com/admin.php?mod=phpcms&file=menu&action=get_menu_list&menuid=4

在URL参数中,file是指请求的控制器文件,这里menu就是指 admin/menu.inc.php这个文件,action 则是方法。我们找到 menu.inc.php 下的 get_menu_list 方法:

case 'get_menu_list':
	$data = $m->get_child($menuid);
	$data = str_charset(CHARSET, 'utf-8', $data);
	$max = array_slice($data, -1);
	$data['max'] = $max[0]['menuid'];
	$data = json_encode($data);
	if(PHP_OS < 5.0) header('Content-type: text/html; charset=utf-8');
	echo $data;
	break;

将其改为:

case 'get_menu_list':
	$data = $m->get_child($menuid);
	
	foreach($data as $k=>$val)
	{
		if( !empty($data[$k]['keyid']) && substr( $data[$k]['keyid'], 0, 5 ) == 'catid' )
		{
			if( $data[$k]['keyid'] == 'catid_0' )
			{
				continue;
			}
			$catid = str_replace("catid_", "", $data[$k]['keyid']);
			
			// 管理权限
			$allow_manage = $priv_role->check('catid', $catid, 'manage');
			
			if(!$allow_manage)
			{
				unset($data[$k]);
			}
		}
	}
	
	$data = str_charset(CHARSET, 'utf-8', $data);
	$max = array_slice($data, -1);
	$data['max'] = $max[0]['menuid'];
	$data = json_encode($data);
	if(PHP_OS < 5.0) header('Content-type: text/html; charset=utf-8');
	echo $data;
	break;

代码存在投机性,但大概思路就是这样。
