展示在注册后的用户注册信息的列表userlist.php
注意：这里和你数据库中的设置的字段名有关
打开数据库
之前连接mysql的时候已经找到DB_DBNAME
userlist.php
<?php
require_once('tpl/header.php');
?>
<form action="">
请输入用户名：
<input type="text" name="key">
<input type="submit" value="搜索">
</form>
<?php
//调用连接数据库函数,返回值是连接号
$con = connect();
$sql = "select * from users ORDER BY uid DESC ";//sql语句
$rs = mysqli_query($con,$sql);
$num = mysqli_num_rows($rs);
?>
<table class="table table-hover">
<caption>共有 <?php
echo $num;
?>

<tr>
<th>用户编号</th>
<th>用户名</th>
<th>性别</th>
<th>生日</th>
<th width='80'>头像</th>
<th>电子邮件</th>

<?php

while ($row = mysqli_fetch_array($rs)){//
?>

需要注意就是图片的路径问题，我弄错了好多次
$frame——图片名是产生的随机数
注册——头像放置的位置，在images中
现在试一下
注册成功之后跳到doUserReg显示信息
在userlist中查看是否数据库中有注册的信息
扫描二维码关注公众号，回复：
4014091 查看本文章
可以看到和我们输入的信息是一致的
完善修改和删除
完成这两个功能
- 搜索
if (isset($_GET["key"])){
$k=$_GET["key"];
$sql = "select * from users WHERE uname LIKE '%$k%'ORDER BY uid DESC ";//sql语句
}
- 删除
$sql="delete from users WHERE uid = $uid";
- 有上传头像（图片）就要找到存放图片的文件夹，文件名，来删除该图片
- 修改的列表中有性别gender，生日birthdate，邮箱email可以修改
流程
从index.php文件中进入首页，注册按钮展示要填写的信息doUserReg.php。然后再打开管理员分页面查看用户的列表userList.php，在这个页面进行修改和删除用户信息。
此外还增加了功能的php文件：
- userDelete.php删除用户
- userEdit.php编辑用户
- userUpdate.php修改用户

表单页面完善之后，点击注册，会跳到doUserReg.php展示
再打开userlist.php文件查看是否有刚才注册的用户展示在列表中
现在看一下怎么删除用户
首先连接数据库
dbConn.php
<?php
define('DB_HOST', 'localhost');
define('DB_USER', 'root');
define('DB_PWD', '');
define('DB_CHARSET', 'UTF8');
define('DB_DBNAME', 'neuvideo');
function connect (){
//连接mysql
// $con = mysqli_connect("localhost:3306","wsw","123","neuvideo") or die("连不上服务器");
$link=mysqli_connect(DB_HOST,DB_USER,DB_PWD,DB_DBNAME) or die ('数据库连接失败<br/>ERROR '.mysqli_errno().':'.mysqli_error());
//设置字符集
mysqli_set_charset($link,DB_CHARSET);
//打开指定的数据库
// mysql_select_db(DB_DBNAME) or die('指定的数据库打开失败'.mysql_error());
return $link;
}
?>
myFunc.php
自定义函数，在每次操作之后会弹出这个空白页加上链接，延迟3s，也可以点击a链接直接回到url的地址
<!-- myFunc.php -->
<?php
//自定义函数，输入提示信息，并在3秒后自动跳转到指定页面
function redirect($url, $msg)
{
echo $msg.'<a href="'.$url.'">如果没有跳转，请点这里跳转</a>';
header("refresh:3;url=$url");
}
?>
inc_admin.php
<?php
define('UserPhotoPath','../images/'); //用户头像存放的路径
define('PosterPicturePath','../posters/');//存放视频海报图片的路径
require_once('../system/myFunc.php');
require_once('../system/dbConn.php');
?>
现在看删除的功能
userDelete.php
- $sql=“select pic from users WHERE uid = $uid”;
- $sql=“delete from users WHERE uid = $uid”;删除键key就会删除该列表项
<?php
require('inc_admin.php');
//链接mysql
$con=connect();
$uid=$_GET["uid"];
$sql="select pic from users WHERE uid = $uid";
$rs = mysqli_query($con,$sql);
$row=mysqli_fetch_array($rs);
//var_dump($row);//打印图片的编号
//exit;
$pic =$row["pic"];
if (file_exists("../images/$pic"))
unlink("../images/$pic");
$sql="delete from users WHERE uid = $uid";
$rs = mysqli_query($con,$sql);
//可以显示删除成功
//返回到userlist
//header("location:userlist.php");
// //自定义函数，输入提示信息，并在3秒后自动跳转到指定页面
if ($rs)
redirect("userlist.php","删除成功！");
else
redirect("userlist.php","删除失败！");
//删除头像——文件夹文件名
?>
点击删除按钮
列表中之前的那个用户就被删除了
现在看编辑用户信息
- enctype=“multipart/form-data”：不对字符编码。在使用包含文件上传控件的表单时，必须使用该值。
<input type="hidden" name="uid" value="<?php echo $uid;?>">
<input type="text" class="form-control" id="username" readonly="readonly" name="uname"
value="<?php echo $row["uname"];?>">
<input type="radio" name="gender" value="0"
<?php if ($row["gender"]==0) echo "checked";?>>男
<input type="radio" name="gender" value="1" <?php if ($row["gender"]==1) echo "checked";?>>女
<input type="date" name="birthdate" class="form-control" value="
<?php echo $row["birthdate"];?>">
<input type="file" name="pic">原头像：<img src="../images/<?php echo $row["pic"]; ?>"width="80px" height="80px" class="img-circle">
<input type="email" name="email" class="form-control" value="
<?php echo $row["email"]; ?>">
<?php
require_once ("tpl/header.php");
$con=connect();
$uid=$_GET["uid"];
$sql="select * from users WHERE uid = $uid";
$rs = mysqli_query($con,$sql);
$row=mysqli_fetch_array($rs);
?>
<!--链接或表单来传参-->
<h3>请修改用户信息</h3>

现在看修改
- $con=connect();//连接数据库
- 获取信息
$uid=$_POST["uid"];
$gender=$_POST["gender"];
$email=$_POST["email"];
$birth=$_POST["birthdate"];
- 判断参数是否传入
这里多讲一点——$FILE函数
使用：
<form enctype="multipart/form-data" action="upload.php" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="1000">
<input name="myFile" type="file">
<input type="submit" value="上传文件">
</form>
然后upload.php中可以直接用
$_FILES
$_POST
$_GET
等函数获取表单内容。当客户端提交后，我们获得了一个$_FILES 数组
$_FILES['myFile']['name'] //客户端文件的原名称。
$_FILES['myFile']['type'] //文件的 MIME 类型，需要浏览器提供该信息的支持，例如"image/gif"。
$_FILES['myFile']['size'] //已上传文件的大小，单位为字节。
$_FILES['myFile']['tmp_name'] //文件被上传后在服务端储存的临时文件名，一般是系统默认。可以在php.ini的upload_tmp_dir 指定，但 用 putenv() 函数设置是不起作用的。
$_FILES['myFile']['error'] //和该文件上传相关的错误代码。['error'] 是在 PHP 4.2.0 版本中增加的。下面是它的说明：(它们在PHP3.0以后成了常量)
UPLOAD_ERR_OK //值：0; 没有错误发生，文件上传成功。
UPLOAD_ERR_INI_SIZE //值：1; 上传的文件超过了 php.ini 中 upload_max_filesize 选项限制的值。
UPLOAD_ERR_FORM_SIZE //值：2; 上传文件的大小超过了 HTML 表单中 MAX_FILE_SIZE 选项指定的值。
UPLOAD_ERR_PARTIAL //值：3; 文件只有部分被上传。
UPLOAD_ERR_NO_FILE
值：4; 没有文件被上传。
值：5; 上传文件大小为0.
文件被上传结束后，默认地被存储在了临时目录中，这时您必须将它从临时目录中删除或移动到其它地方，如果没有，则会被删除。也就是不管是否上传成功，脚本执行完后临时目录里的文件肯定会被删除。所以在删除之前要用PHP的 copy() 函数将它复制到其它位置，此时，才算完成了上传文件过程。
//修改的sql语句
$sql="update users set email = '$email',gender='$gender',birthdate='$birth',pic='$fname' WHERE uid=$uid";
- 执行——修改命令
$sql="update users set email = '$email',gender='$gender',birthdate='$birth',pic='$fname' WHERE uid=$uid";
完整修改的代码userUpdate.php
<?php
require('inc_admin.php');
$con=connect();//连接数据库
//获取信息
$uid=$_POST["uid"];
$gender=$_POST["gender"];
$email=$_POST["email"];
$birth=$_POST["birthdate"];
//判断参数是否传入
if ($_FILES["pic"]["error"]==4){//没有上传
$sql="update users set email = '$email',gender='$gender',birthdate='$birth' WHERE uid=$uid";
}else{
//文件名
$arr=explode(".",$_FILES["pic"]["name"]);//把原文件名切割
$ex=$arr[count($arr)-1];//获得扩展名
$fname=date("YmdHis").rand(100,999).".".$ex;
move_uploaded_file($_FILES["pic"]["tmp_name"], "..images/$fname");///////将上传的文件放到upload里
$sql="update users set email = '$email',gender='$gender',birthdate='$birth',pic='$fname' WHERE uid=$uid";
}
//执行
$rs=mysqli_query($con,$sql);
redirect("userlist.php","修改成功！");
?>
除了用户名其他都可以修改
原来：
现在修改成功
