PHP后台用户管理
php后台用户管理
如果有不理解的小伙伴可以私信我
1.用户登录界面
2.登录完成后的数据库管理界面
3.增加数据库值得HTML
首先我们需要对数据库进行配置
下面是我的两个数据库连接配置
1.
define("HOST1","localhost");
define("USER1","root");
define("PASS1","12345678");
define("DBNAME1","test");
?>2.
define("HOST","localhost");
define("USER","root");
define("PASS","12345678");
define("DBNAME","test001");
?>在这里插入PHP的register用户管理界面的代码片

</html>然后是对这个界面的数据库进行增删改查
首先是增加数据的HTML<!DOCTYPE html>
<html>
<head lang="en"> <meta charset="UTF-8"> <title>添加人员</title>
</head>
<style type="text/css">form{margin: 20px;}
</style>
<body>
<form action="action-addnews1.php" method="post"> <!-- <label>Openid：</label><input type="text" name="openid"> --><label>预约部门：</label><input type="text" name="YuYueBuMen"> <label>预约部门人：</label><input type="text" name="YuYueBuMenPeople"> <label>来的时间：</label><input type="date" name="ComeTime"> <label>离开时间：</label><input type="date" name="LiftTime"> <label>来访人姓名：</label><input type="text" name="ComePeople"> <label>来访原因：</label><input type="text" name="Work"> <label>事件：</label><input type="text" name="Thing"> <label>来访方式：</label><input type="text" name="Way"> <label>电话号码：</label><input type="text" name="Telephone"> <label>申请时间：</label><input type="date" name="LockDate"> <input type="submit" value="提交">
</form>
</body>
</html>然后对应着该HTML进行他的PHP操作
这里有一个点就是我们要通过算法对每增加一条新数据就使得该数据
成为第一条数据（我这里用的算法是自己写的不一定是最简便的）
<!DOCTYPE html>
<html>
<body>
use function PHPSTORM_META\type;require "dbconfig.php";
$link = mysqli_connect(HOST,USER,PASS,DBNAME) or die("提示：数据库连接失败！");
mysqli_set_charset($link,'utf-8');
$sql1='select * from user order by openid ';
$result=mysqli_query($link,$sql1);
$num=mysqli_num_rows($result);
if(!empty($num)){$openid=$num+1;}else{$openid=1;}
$YuYueBuMen=$_POST['YuYueBuMen'];
$YuYueBuMenPeople = $_POST['YuYueBuMenPeople'];
$ComeTime =$_POST['ComeTime'];
$LiftTime =$_POST['LiftTime'];
$ComePeople =$_POST['ComePeople'];
$Work =$_POST['Work'];
$Thing =$_POST['Thing'];
$Way=$_POST['Way'];
$Telephone=$_POST['Telephone'];
$alive= "待审核";
$LockDate=$_POST['LockDate'];$sql = "INSERT INTO user(openid,YuYueBuMen,YuYueBuMenPeople,ComeTime,LiftTime,ComePeople,Work,Thing,Way,Telephone,LockDate,alive)
VALUES('$openid','$YuYueBuMen','$YuYueBuMenPeople','$ComeTime','$LiftTime','$ComePeople','$Work','$Thing','$Way','$Telephone','$LockDate','$alive')";
if (mysqli_multi_query($link, $sql)) {echo "新记录插入成功";$sql2='SELECT * from user';// $openid2=$_GET['openid'];$result1=mysqli_query($link,$sql2);$num1=mysqli_num_rows($result1);$j=$num1+1;$m=$num1+1;$l=$num1-1;echo"$m";for($i=0;$i<$m;$i++){ $sql3="UPDATE user set openid=$j where openid = '$num1'";mysqli_query($link,$sql3)or die ("错误".mysqli_error($link));$j--;$num1--;echo " $j";echo"$num1";if($j==1){echo"$j";$sql4="UPDATE user set openid=$j where openid='$m'";mysqli_query($link,$sql4)or die ("错误".mysqli_error($link));break;// header("Location:phptest.php"); }// header("Location:phptest.php"); }
} else {echo "Error: " . $sql . "
" . mysqli_error($link);
}
// ,'$YuYueBuMen','$YuYueBuMenPeople','$ComeTime','$LiftTime','$ComePeople','$Work','$Thing','$Way','$Telephone','$LockDate','$alive'
//,YuYueBuMen,YuYueBuMenPeople,ComeTime,LiftTime,ComePeople,Work,Thing,Way,Telephone,LockDate,alive
?></body>
</html>接下来我们就对数据进行删除该数据操作
要点就是要先识别要删除数据所在一行的主键（我这里是openid）
并且我们要完成每删除一行数据下一行数据的id会向前减1
接下来就是代码
session_start();require "dbconfig.php";$link =mysqli_connect(HOST,USER,PASS,DBNAME)or die("提示：数据库连接失败！");mysqli_set_charset($link,'UTF-8');// $openid=mysqli_insert_id($openid);// echo"$getID";$getopenid = $_GET['openid'];// echo"$openid";$sql1='select * from user';$result=mysqli_query($link,$sql1);$num=mysqli_num_rows($result);$num1=$num-$getopenid;echo"$num1";$sql="DELETE FROM user WHERE openid='$getopenid'"or die('删除数据出错：'.mysqli_error($link)); if (mysqli_multi_query($link, $sql)) {echo "新记录插入成功";for($i=0;$i<$num1;$i++){// echo"$getopenid";$getopenid++;// echo"$getopenid";$openid1=$getopenid-1;// echo"$openid1";$sql2="UPDATE user SET openid = $openid1where openid='$getopenid'";mysqli_query($link,$sql2)or die ('出错'.mysqli_error($link));}header("Location:phptest.php"); } else {echo "Error: " . $sql . "
" . mysqli_error($link);}?>然后是我们对审核的数据（待审核）进行审核
我们通过在数据里定义一个alive值默认为待审核
通过JavaScript对PHP对alive值进行改变
下面是同意和不同意的代码1.审核通过代码require "dbconfig.php";$link =mysqli_connect(HOST,USER,PASS,DBNAME)or die("提示：数据库连接失败！");mysqli_set_charset($link,'utf-8');// $openid=mysqli_insert_id($openid);// echo"$getID";$openid = $_GET['openid'];echo"$openid";$sql="UPDATE user set alive='通过' where openid='$openid'";//or die('删除数据出错：'.mysqli_error($link)); // $sql = 'update user set alive = "通过" from user WHERE openid={$openid}';// mysqli_query($link,$sql);if (mysqli_multi_query($link, $sql)) {echo "新记录插入成功";header("Location:phptest.php"); } else {echo "Error: " . $sql . "
" . mysqli_error($link);}?>2.不同意代码require "dbconfig.php";$link =mysqli_connect(HOST,USER,PASS,DBNAME)or die("提示：数据库连接失败！");mysqli_set_charset($link,'utf-8');// $openid=mysqli_insert_id($openid);// echo"$getID";$openid = $_GET['openid'];echo"$openid";$sql="UPDATE user set alive='不通过' where openid='$openid'";//or die('删除数据出错：'.mysqli_error($link)); // $sql = 'update user set alive = "通过" from user WHERE openid={$openid}';// mysqli_query($link,$sql);if (mysqli_multi_query($link, $sql)) {echo "新记录插入成功";header("Location:phptest.php"); } else {echo "Error: " . $sql . "
" . mysqli_error($link);}?>本文来自互联网用户投稿，文章观点仅代表作者本人，不代表本站立场，不承担相关法律责任。如若转载，请注明出处。 如若内容造成侵权/违法违规/事实不符，请点击【内容举报】进行投诉反馈！
