摘要：php 人员权限管理(RBAC)实例(推荐)

[b]php-人员权限管理（RBAC）[/b] 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[b]：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[/b] [img]http://files.jb51.net/file_images/article/201705/201705240751008.png[/img] [b]我用到的五张表如下：[/b] [img]http://files.jb51.net/file_images/article/201705/201705240751009.png[/img] [img]http://files.jb51.net/file_images/article/201705/2017052407510010.png[/img] [img]http://files.jb51.net/file_images/article/201705/2017052407510011.png[/img] [img]http://files.jb51.net/file_images/article/201705/2017052407510012.png[/img] [img]http://files.jb51.net/file_images/article/201705/2017052407510013.png[/img] [b]一. 首先写的是管理员页面[/b] [b]1.用下拉列表显示用户名[/b]

<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>

[img]http://files.jb51.net/file_images/article/201705/2017052407510014.png[/img] [b]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[/b]

<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/>

[img]http://files.jb51.net/file_images/article/201705/2017052407510015.png[/img] [b]3.为了修改权限加一个确认保存按钮[/b]

<input type="button" value="保存" id="baocun" />

[img]http://files.jb51.net/file_images/article/201705/2017052407510016.png[/img] [b]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[/b] 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);
            }
          }
        }
       
    })
}

[b]5.各项值的处理页面 [/b]

<?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： [img]http://files.jb51.net/file_images/article/201705/2017052407510017.png[/img] [b]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[/b]

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！");
        }
    })
  })

[b]7.保存的处理页面[/b]

<?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： [img]http://files.jb51.net/file_images/article/201705/2017052407510018.png[/img] [img]http://files.jb51.net/file_images/article/201705/2017052407510019.png[/img] 下面代码用来copy用，[b]注意AJAX需要引用Jquery[/b] [b]1.guanli.php[/b]

else
{
  echo"输入的用户名或密码有误！";
