朋友你好我在這段代碼有問題, 當我刷新網頁,然後數據自動插入到數據的基礎上,我那麼做數據未連連插入數據庫時,頁面加載。 這是我的代碼 -如何停止的數據重新輸入到數據庫時,頁面刷新
<?php
require './database/databaseConnection.php';
if(isset($_POST['save_button']))
{
if(($_POST['fname']&&($_POST['lname'])))
{
$first_name=$_POST['fname'];
$last_name=$_POST['lname'];
$qry="INSERT INTO user_master(first_name,last_name) values('$first_name','$last_name')";
$result= mysql_query($qry)or die(mysql_error());
if($result){
echo 'SuccessFully saved data';
}
else{
echo 'Data Not Inserted!';
}
}
}
?>
