linux学习之——数据操作：添加与查询

时间：2021-11-04 06:55:16

说明：

在linux系统中，利用搭建的服务器，编写两个页面，一个添加信息，一个展现信息；

主要涉及到：php+mysql的操作；

数据添加页面：

<html>

<head>

<meta http-equiv='content-type' content='text/html'; charset='utf-8'>

<title> Test Engineer info table add</title>

</head>

<body>

<div align='center'>

<form action='adduser.php' method='post'>

<h3> Test Engineer_info Table</h3>

<table width='500' bgcolor='#ccffcc' style='border-color' border='1'>

<tr align=center><td>name</td><td><input type="text" name="tname"/></td></tr>

<tr align=center><td>age</td><td><input type="text" name="tage"/></td></tr>

<tr align=center><td>hobby</td><td><input type="text" name="thobby"/></td></tr>

<tr align=center> <td>job</td><td><input type="text" name="tjob"/></td></tr>

<tr align=center><td colspan='2'><input type="submit" value="add info"></td></tr>

</table>

</form>

</div>

</body>

</html>

数据操作：

<?php

 $mysql_server_name= 'localhost';

 $mysql_username='mysqlname';

 $mysql_password='mysqlpassword';

 $mysql_database='mysql-database';

 $tname=$_POST[tname];

 $tage=$_POST[tage];

 $thobby=$_POST[thobby];

 $tjob=$_POST[tjob];

 $link = mysql_connect($mysql_server_name,$mysql_username,$mysql_password);

 mysql_query("set names'utf8'");

  if (!$link)

     die('could not connect:' .mysql_error());

  else {

        /*echo "LAMP is success!MySql is right!Mysql_database is right";*/

        mysql_select_db( $mysql_database,$link);

        if(!empty($tname)){

    $sql_insert="insert into clt_testerinfo values('$tname','$tage','$thobby','$tjob')";

    mysql_query($sql_insert);

    }

        $sql_select="select * from  clt_testerinfo";

        $result=mysql_query($sql_select,$link);

     echo "Test Enginner info Table";

     echo '</br>';

     echo "<table width='800' bgcolor='#ccffcc' style='border-color' border='1'>";

     echo "<tr><td>name</td>";

     echo "<td>age</td>";

     echo "<td>hobby</td>";

     echo "<td>job</td></tr>";

     while($row = mysql_fetch_array($result))

    {

     echo "<tr><td>";

     echo $row[tname];

     echo "</td><td>";

     echo $row[tage];

     echo "</td><td>";

     echo $row[thobby];

     echo "</td><td>";

     echo $row[tjob];

     echo "</td></tr>";

    }

     echo "</table>";

    }

  mysql_close($link);

?>
