Code for writing PHP form data to MySQL database

This article mainly introduces the relevant information about writing PHP form data into the MySQL database. It is very good and has reference value. Friends who need it can refer to it.

No more nonsense, I will directly post the code for everyone. , the specific code is as follows:

<h插入操作</h 
<?php 
if(!isset($_POST[&#39;submit&#39;])){ 
//如果没有表单提交，显示一个表单 
?> 
<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> 
<?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[&#39;country&#39;])? die("请输入国家名称"): 
mysql_escape_string($_POST[&#39;country&#39;]); 
$animal = empty($_POST[&#39;animal&#39;])? die("请输入英文名"): 
mysql_escape_string($_POST[&#39;animal&#39;]); 
$cname = empty($_POST[&#39;cname&#39;])? die("请输入中文名"): 
mysql_escape_string($_POST[&#39;cname&#39;]); 
//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 
$query = "INSERT INTO symbols(country, animal, cname) VALUE(&#39;$country&#39;, &#39;$animal&#39;, &#39;$cname&#39;)"; 
//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); 
} 
?>

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

<h插入操作</h 
<?php 
if(!isset($_POST[&#39;submit&#39;])){ 
//如果没有表单提交，显示一个表单 
?> 
<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> 
<?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[&#39;country&#39;])? die("请输入国家名称"): 
mysql_escape_string($_POST[&#39;country&#39;]); 
$animal = empty($_POST[&#39;animal&#39;])? die("请输入英文名"): 
mysql_escape_string($_POST[&#39;animal&#39;]); 
$cname = empty($_POST[&#39;cname&#39;])? die("请输入中文名"): 
mysql_escape_string($_POST[&#39;cname&#39;]); 
//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 
$query = "INSERT INTO symbols(country, animal, cname) VALUE(&#39;$country&#39;, &#39;$animal&#39;, &#39;$cname&#39;)"; 
//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); 
} 
?>
