一、增加数据
用bootstrap做
<link href="bootstrap.min.css" rel="stylesheet" type="text/css" /> <script src="bootstrap.min.js"></script> <script src="jquery-1.11.2.min.js"></script>
然后访问数据库
<body> <table class="table table-striped"> <caption>人员信息展示</caption> <thead> <tr> <th>代号</th> <th>姓名</th> <th>性别</th> <th>民族</th> <th>生日</th> </tr> </thead> <tbody> <?php $a = new mysqli("localhost","root","123456","crud"); if(mysqli_connect_error()){ echo "错误"; } $sql = "select info.code,info.name,sex,nation.name,birthday from info,nation where info.nation=nation.code"; $result = $a->query($sql); if($result){ $attr = $result->fetch_all(); foreach($attr as $v){ $sex = $v[2]?"男":"女";//三元运算 把性别的1/0(1为ture 0为false)改为男女 echo "<tr> <td>{$v[0]}</td> <td>{$v[1]}</td> <td>{$sex}</td> <td>{$v[3]}</td> <td>{$v[4]}</td> </tr>"; } }else{ echo "出错"; } ?> </tbody> </table> <div><a href="tianjia.php">添加数据</a></div> </body>
tianjia.php文件
<!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"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题文档</title> <link href="bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css" /> <script src="bootstrap/js/jquery-1.11.2.min.js"></script> <script src="bootstrap/js/bootstrap.min.js"></script> </head> <body> <h1>添加数据</h1> <form action="./add.php" method="post"> <div class="panel panel-default" style="max-width:500px"> <div class="panel-body"> <div class="input-group"> <span class="input-group-addon">代号:</span> <input type="text" class="form-control" placeholder="请输入代号" name="code"> </div> <br /> <div class="input-group"> <span class="input-group-addon">姓名:</span> <input type="text" class="form-control" placeholder="请输入姓名" name="name"> </div> <br /> <div class="input-group"> <span class="input-group-addon">性别:</span> 男<input type="radio" name="sex" value="1" /> 女<input type="radio" name="sex" value="0" /> </div> <br /> <div class="input-group"> <span class="input-group-addon">民族:</span> <select name="nation"> <?php $db = new MySQLi("localhost","root","123","mydb"); $sql = "select * from nation"; $result = $db->query($sql); if($result){ $arr = $result->fetch_all(); foreach($arr as $v){ echo "<option value=\'{$v[0]}\'>{$v[1]}</option>"; } } ?> </select> </div> <br /> <div class="input-group"> <span class="input-group-addon">生日:</span> <input type="text" class="form-control" placeholder="请输入生日" name="birthday"> </div> <br /> <input class="btn btn-default" type="submit" value="添加数据"> </div> </div> </form> </body>
add.php文件
<?php $code = $_POST["code"]; $name = $_POST["name"]; $sex = (int)$_POST["sex"]; $nation = $_POST["nation"]; $birthday = $_POST["birthday"]; $db = new MySQLi("localhost","root","123456","crud"); if(mysqli_connect_error()){ echo "错误"; } $sql = "insert into info values(\'{$code}\',\'{$name}\',{$sex},\'{$nation}\',\'{$birthday}\')"; $result = $db->query($sql); if($result){ echo "<script type=\'text/javascript\'>window.location.href=\'tianjia.php\';</script>"; }else{ echo"添加失败"; }
二、删除数据
<!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"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>无标题文档</title> <link href="bootstrap.min.css" rel="stylesheet" type="text/css" /> <script src="bootstrap.min.js"></script> <script src="jquery-1.11.2.min.js"></script> </head> <body> <table class="table table-striped"> <caption>人员信息展示</caption> <thead> <tr> <th>代号</th> <th>姓名</th> <th>性别</th> <th>民族</th> <th>生日</th> <th>操作</th> </tr> </thead> <tbody> <?php $a = new MySQLi("localhost","root","123456","crud"); if(mysqli_connect_error()){ echo "错误"; } $sql = "select info.code,info.name,sex,nation.name,birthday from info,nation where info.nation=nation.code"; $result = $a->query($sql); if($result){ $attr = $result->fetch_all(); foreach($attr as $v){ $sex = $v[2]?"男":"女";//三元运算 把性别的1/0(1为ture 0为false)改为男女 echo "<tr> <td>{$v[0]}</td> <td>{$v[1]}</td> <td>{$sex}</td> <td>{$v[3]}</td> <td>{$v[4]}</td> <td><a href=\'delete.php?code={$v[0]}\' onclick=\\"return confirm(\'确认删除么?\')\\"><button type=\'button\' class=\'btn btn-primary btn-sm\'>删除</button></a></td> </tr>"; } }else{ echo "出错"; } ?> </tbody> </table> </body> </html>
delete.PHP文件
<?php $code = $_GET["code"]; $db = new MySQLi("localhost","root","123","mydb"); $sql = "delete from info where code=\'{$code}\'"; $result = $db->query($sql); if($result){ header("location:main.php"); }else{ echo "删除失败!"; }
