php-人员权限管理(RBAC)
权限管理可以想做vip的功能,普通用户和vip用户的功能是不一样的,大致会用到五张表:用户表、角色表、功能表,还有他们之间互相关联的表:用户与角色表、角色与功能表
我用到的五张表如下:
一.首先写的是管理员页面
1.用下拉列表显示用户名
1

4
5

7
8
9
10
11

<div> <select id= "user" > <?php require "../DBDA.class.php" ; $db = new DBDA(); $sql = "select * from users" ; $arr = $db ->query( $sql ,1); foreach ( $arr as $v ) { echo "<option value=\'{$v[0]}\'>{$v[2]}</option>" ; } ?> </select> </div> |
2.因为上面已经造了新对象,所以在显示角色名时直接从SQL语句开始写
1
2
3
4
5
6
7
8
9
10
11
|
<div>请选择角色: <?php $sql = "select * from juese" ; $arr = $db ->query( $sql ,1); foreach ( $arr as $v ) { echo "<input type=\'checkbox\' class=\'ck\' value=\'{$v[0]}\'/>{$v[1]}" ; } ?> </div> <br/> |
3.为了修改权限加一个确认保存按钮
1
|
<input type= "button" value= "保存" id= "baocun" /> |
4.这样,再考虑怎么让数据库中用户本有的角色显示出来,那就是要用到下拉列表和复选框的值了
可以把它写入方法里,然后调用这个方法

function Xuan() { var uid = $( "#user" ).val(); $.ajax({ url: "chuli.php" , data:{uid:uid}, type: "POST" , dataType: "TEXT" , success: function (data){ var js = data.trim().split( "|" ); var ck = $( ".ck" ); ck.prop( "checked" ,false); for ( var i=0;i<ck.length;i++) { var v = ck.eq(i).val(); if (js.indexOf(v)>=0) { ck.eq(i).prop( "checked" ,true); } } } }) } |
5.各项值的处理页面

<?php require "../DBDA.class.php" ; $db = new DBDA(); $uid = $_POST [ "uid" ]; $sql = "select jueseid from userinjuese where userid=\'{$uid}\'" ; echo $db ->strquery( $sql ); |
效果如下:
6.最后就是保存修改后的值了,可以直接用全部删除在重新写入的方法来进行值的选择;对保存按钮添加单击事件

Xuan(); $( "#user" ).change( function (){ Xuan(); }) $( "#baocun" ).click( function (){ var uid = $( "#user" ).val(); var str = "" ; var ck = $( ".ck" ); for ( var i=0;i<ck.length;i++) { if (ck.eq(i).prop( "checked" )) { str = str + ck.eq(i).val()+ "," ; } } str = str. substr (0,str.length-1); $.ajax({ url: "add.php" , data:{uid:uid,js:str}, type: "POST" , dataType: "TEXT" , success: function (data){ alert( "保存成功!" ); } }) }) |
7.保存的处理页面

<?php require "../DBDA.class.php" ; $db = new DBDA(); $uid = $_POST [ "uid" ]; $js = $_POST [ "js" ]; //清空原有角色 $sql = "delete from userinjuese where userid=\'{$uid}\'" ; $db ->query( $sql ); //添加选中的角色 $ajs = explode ( "," , $js ); foreach ( $ajs as $v ) { $sql = "insert into userinjuese values(\'\',\'{$uid}\',\'{$v}\')" ; $db ->query( $sql ); } |
效果如下:
下面代码用来copy用,注意AJAX需要引用Jquery
