php登录页面:
<h1>登录界面</h1> <form action="dengluchuli.php" method="post"> 用户名:<input type="text" name="uid"/> 密码:<input type="text" name="pwd"/> <input type="submit" value="登录" /> </form>
其中 dengluchuli.php在规定路径下。
登录跳转页面:
<?php $yonghuming = $_POST["uid"]; $mima = $_POST["pwd"]; $db = new mysqli("localhost","root","","12345"); $sql = "select password from login where username=\'{$yonghuming}\'"; $result = $db->query($sql); $atter = $result->fetch_row(); if($atter[0]==$mima && !empty($mima)) { header("location:xinxi.php"); } else { echo "用户名或密码错误"; } ?>
此页面用于登录界面登录成功后通过用户名找到相应的数据。
登录主界面:
<?php $de = new mysqli("localhost","root","","12345"); $e="select * from info"; $result = $de->query($e); $atter = $result->fetch_all(); echo "<table border=1>"; echo "<tr> <td>代号</td> <td>姓名</td> <td>性别</td> <td>民族</td> <td>出生日期</td> <td>操作</td> </tr> "; for($i=0;$i<count($atter);$i++) { echo "<tr>"; for($j=0;$j<count($atter[$i]);$j++) { if($j==4) { echo "<td>".$atter[$i][$j]."</td> <td><a href=\'shanchu.php?code={$atter[$i][1]}\' onclick=\\"return confirm(\'确定删除?\')\\"> 删除</a></td>"; } else { echo "<td>".$atter[$i][$j]."</td>"; } } echo "</tr>"; } echo " </table>"; echo "<a href=\'tianjia.php\'>添加数据</a>" ?>
添加数据(tianji.php):
<h1>添加数据</h1> <form action="zeng.php" method="post"> 代号:<input type="text" name="daihao" /> <br /> 姓名:<input type="text" name="xinming" /><br /> 性别:<input type="text" name="xinbie" /><br /> 民族:<input type="text" name="minzu" /><br /> 生日:<input type="text" name="shengri" /><br /> <input type="submit" value="提交"/> </form>
zeng.php :
<?php $code = $_POST["daihao"]; $name = $_POST["xinming"]; $sex = $_POST["xinbie"]; $nation = $_POST["minzu"]; $birthday = $_POST["shengri"]; $db = new mysqli("localhost","root","","12345"); $sql = "insert into info values(\'{$code}\',\'{$name}\',\'{$sex}\',\'{$nation}\',\'{$birthday}\')"; $r = $db->query($sql); if($r) { header("location:xinxi.php"); } else { echo "添加失败"; } ?>
添加成功:
shanchu.php
<?php $name = $_GET["code"]; $db = new mysqli("localhost","root","","12345"); $sql = "delete from info where name=\'{$name}\'"; $result = $db->query($sql); if($result) { header("location:xinxi.php"); } else { echo "删除失败"; } ?>
修改数据:
在xinxi.php文件中插入代码:
<a href=\'xiugai.php?code={$atter[$i][1]}\'>修改</a>
相同路径下新建xiugai.php
<?php $name = $_GET["code"]; $db = new mysqli("localhost","root","","12345"); $sql = "select * from info where name=\'{$name}\'"; $r = $db->query($sql); $atter = $r->fetch_row(); ?> <h1>修改</h1> <form action="xiugaichuli.php" method="post"> <input type="hidden" name="daihao" value="<?php echo $atter[0]; ?>" /> <br /> 姓名: <input type="text" name="xinming" value="<?php echo $atter[1]; ?>"/> <br /> 性别: <input type="text" name="xinbie" value="<?php echo $atter[2]; ?>"/> <br /> 民族: <input type="text" name="minzu" value="<?php echo $atter[3]; ?>"/> <br /> 生日: <input type="text" name="shengri" value="<?php echo $atter[4]; ?>"/> <br /> <input type="submit" value="修改" /> </form>
相同路径下新建xiugaichuli.php
<?php $code = $_POST["daihao"]; $name = $_POST["xinming"]; $sex = $_POST["xinbie"]; $nation = $_POST["minzu"]; $birthday = $_POST["shengri"]; $db = new mysqli("localhost","root","","12345"); $sql = "update info set name=\'{$name}\',sex={$sex},nation=\'{$nation}\',birthday=\'{$birthday}\' where code=\'{$code}\'"; $r = $db->query($sql); if($r) { header("location:xinxi.php"); } else { echo "修改失败"; } ?>
点击修改其中一条数据:
修改成功。
