PHP表单数据写入MySQL数据库的代码_php实例

May 26, 2018 pm 02:03 PM

废话不多说了,直接给大家贴代码了,具体代码如下所示:

<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); 
} 
?>
Copy after login

上面的代码用不同格式,不知道哪种格式更好

<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); 
} 
?>
Copy after login
