Code for writing PHP form data to MySQL database, php form mysql database_PHP tutorial

The code for writing PHP form data into MySQL database, PHP form mysql database

Without further ado, I will post the code directly for you. The specific code is as follows:

<h插入操作</h 
<&#63;php 
if(!isset($_POST['submit'])){ 
//如果没有表单提交，显示一个表单 
&#63;> 
<form action="" method="post"> 
国家：<input type="text" name="country" /> 
动物名称（英文）：<input type="text" name="animal" /> 
动物名称（中文）：<input type="text" name="cname" /> 
<input type="submit" name="submit" value="提交表单" /> 
</form> 
<&#63;php 
} 
else 
{ 
//如果提交了表单 
//数据库连接参数 
$host = "localhost"; 
$user = "root"; 
$pass = "zq"; 
$db = "phpdev"; 
// 何问起 hovertree.com
//取得表单中的值，检查表单中的值是否符合标准，并做适当转义，防止SQL注入 
$country = empty($_POST['country'])&#63; die("请输入国家名称"): 
mysql_escape_string($_POST['country']); 
$animal = empty($_POST['animal'])&#63; die("请输入英文名"): 
mysql_escape_string($_POST['animal']); 
$cname = empty($_POST['cname'])&#63; die("请输入中文名"): 
mysql_escape_string($_POST['cname']); 
//打开数据库连接 
$connection = mysql_connect($host, $user, $pass) or die("Unable to connect!"); 
//选择数据库 
mysql_select_db($db) or die("Unable to select database!"); 
//构造一个SQL查询 
$query = "INSERT INTO symbols(country, animal, cname) VALUE('$country', '$animal', '$cname')"; 
//执行该查询 
$result = mysql_query($query) or die("Error in query: $query. ".mysql_error()); 
//插入操作成功后，显示插入记录的记录号 
echo "记录已经插入， mysql_insert_id() = ".mysql_insert_id(); 
//关闭当前数据库连接 
mysql_close($connection); 
} 
&#63;> 

The above code uses different formats, I don’t know which format is better

<h插入操作</h 
<&#63;php 
if(!isset($_POST['submit'])){ 
//如果没有表单提交，显示一个表单 
&#63;> 
<form action="" method="post"> 
国家：<input type="text" name="country" /> 
动物名称（英文）：<input type="text" name="animal" /> 
动物名称（中文）：<input type="text" name="cname" /> 
<input type="submit" name="submit" value="提交表单" /> 
</form> 
<&#63;php 
} 
else 
{ 
//如果提交了表单 
//数据库连接参数 
$host = "localhost"; 
$user = "root"; 
$pass = "zq"; 
$db = "phpdev"; 
//取得表单中的值，检查表单中的值是否符合标准，并做适当转义，防止SQL注入 
$country = empty($_POST['country'])&#63; die("请输入国家名称"): 
mysql_escape_string($_POST['country']); 
$animal = empty($_POST['animal'])&#63; die("请输入英文名"): 
mysql_escape_string($_POST['animal']); 
$cname = empty($_POST['cname'])&#63; die("请输入中文名"): 
mysql_escape_string($_POST['cname']); 
//打开数据库连接 hovertree.com 何问起 
$connection = mysql_connect($host, $user, $pass) or die("Unable to connect!"); 
//选择数据库 
mysql_select_db($db) or die("Unable to select database!"); 
//构造一个SQL查询 
$query = "INSERT INTO symbols(country, animal, cname) VALUE('$country', '$animal', '$cname')"; 
//执行该查询 
$result = mysql_query($query) or die("Error in query: $query. ".mysql_error()); 
//插入操作成功后，显示插入记录的记录号 
echo "记录已经插入， mysql_insert_id() = ".mysql_insert_id(); 
//关闭当前数据库连接 
mysql_close($connection); 
}
