php example-php personnel authority management (RBAC) example (recommended)

The following editor will bring you an example of PHP personnelPermission management(RBAC) (recommended). The editor thinks it is quite good, so I will share it with you now and give it as a reference for everyone. Let’s follow the editor and take a look.

php-Personnel Rights Management (RBAC)

Permission management can be used as a VIP function, ordinary The functions of users and VIP users are different. There are roughly five tables used: user table, role table, function table, and tables related to each other: user and role table, role And the function table

The five tables I use are as follows:

## 1. The first thing to write is the administrator page

1. Use the drop-down

list to display username

<p>
  <select id="user">
  <?php
  require"../DBDA.class.php";
  $db = new DBDA();
  $sql = "select * from users";
  $arr = $db->query($sql,1);
  foreach($arr as $v)
  {
    echo"<option value=&#39;{$v[0]}&#39;>{$v[2]}</option>";
  }
  ?>
  </select>
</p>

2. Because a new object has been created above, when displaying the role name, write directly from the SQL statement

<p>请选择角色：
  <?php
  $sql = "select * from juese";
  $arr = $db->query($sql,1);
  foreach($arr as $v)
  {
    echo "<input type=&#39;checkbox&#39; class=&#39;ck&#39; value=&#39;{$v[0]}&#39;/>{$v[1]}";
  }
  ?>
</p>
<br/>

3. Add a confirm save button to modify permissions

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

#4. In this way, consider how to display the user's original role in the database, that is to use

drop-down list and When the value of the check box is determined, you can write it into the method and then call this method

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. Processing of each value Page

<?php
require"../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$sql = "select jueseid from userinjuese where userid=&#39;{$uid}&#39;";
echo $db->strquery($sql);

The effect is as follows:

6. The last step is to save the modified value, OK Directly use the delete all and rewrite method to select values; add a click event to the save button

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. Save processing page

<?php
require "../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$js = $_POST["js"];
 
//清空原有角色
$sql = "delete from userinjuese where userid=&#39;{$uid}&#39;";
$db->query($sql);
 
//添加选中的角色
$ajs = explode(",",$js);
 
foreach($ajs as $v)
{
  $sql = "insert into userinjuese values(&#39;&#39;,&#39;{$uid}&#39;,&#39;{$v}&#39;)";
  $db->query($sql);
}

The effect is as follows:

##The following code is for copying,

Note that AJAX needs to reference Jquery

##1.guanli.php

 

用户角色对应
<p>
  <select id="user">
  <?php
  require"../DBDA.class.php";
  $db = new DBDA();
  $sql = "select * from users";
  $arr = $db->query($sql,1);
  foreach($arr as $v)
  {
    echo"<option value=&#39;{$v[0]}&#39;>{$v[2]}</option>";
  }
  ?>
  </select>
</p>


<p>请选择角色：
  <?php
  $sql = "select * from juese";
  $arr = $db->query($sql,1);
  foreach($arr as $v)
  {
    echo "<input type=&#39;checkbox&#39; class=&#39;ck&#39; value=&#39;{$v[0]}&#39;/>{$v[1]}";
  }
  ?>
</p>
<br/>
<input type="button" value="保存" id="baocun" />
 

2. chuli.php

<?php
require"../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$sql = "select jueseid from userinjuese where userid=&#39;{$uid}&#39;";
echo $db->strquery($sql);

3. Saved processing page add.php

<?php
require "../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$js = $_POST["js"];
 
//清空原有角色
$sql = "delete from userinjuese where userid=&#39;{$uid}&#39;";
$db->query($sql);
 
//添加选中的角色
$ajs = explode(",",$js);
 
foreach($ajs as $v)
{
  $sql = "insert into userinjuese values(&#39;&#39;,&#39;{$uid}&#39;,&#39;{$v}&#39;)";
  $db->query($sql);
}

2. After completing the administrator page, the following is the login page

1. Log in to the basic page login.php

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>无标题文档</title>
</head>
 
<body>
<h1 id="登录界面">登录界面</h1>
<form action="dlchuli.php" method="post">

<p>密码：  <input type="password" name="pwd" /></p>
<input type="submit" value="登录" />
</form>
</body>
</html>

2. Login processing page dlchuli.php

<?php
session_start();
 
 
require "../DBDA.class.php";
$db = new DBDA();
$uid = $_POST["uid"];
$pwd = $_POST["pwd"];
$sql = "select pwd from users where uid=&#39;{$uid}&#39;";
$mm = $db->strquery($sql);
if($mm==$pwd && !empty($pwd))
{
  $_SESSION["uid"] = $uid;
  header("location:main.php");
}
else
{
  echo"输入的用户名或密码有误！";
}

3. Main page main.php

    line-height:35px;}
</style>
</head>
 
<body>
<h1 id="主页面">主页面</h1>
<?php
session_start();
$uid ="";
if(empty($_SESSION["uid"]))<code class="php comments">//判断session是否为空</code>
{
  header("location:login.php");<code class="php comments">//空的话就返回登录页面</code>
  exit;
}
 
$uid = $_SESSION["uid"];
 
require"../DBDA.class.php";
$db = new DBDA();
$sql = "select * from rules where code in(select distinct ruleid from juesewithrules where jueseid in(select jueseid from userinjuese where userid=&#39;{$uid}&#39;))";
 
$arr = $db->query($sql,1);
foreach($arr as $v)
{
  echo "<p code=&#39;{$v[0]}&#39; class=&#39;list&#39;>{$v[1]}</p>";
}
 
?>
</body>
</html>
