在我的項目不保存選定的微調值我使用一個微調項目有3個edittexts fields..here我正在通過URL發送這些值，而這又是PHP文件將這些值存儲到PHP文件數據庫...如果我在程序中使用只有三場的EditText，它被存儲到database..Now我的問題是什麼，所選擇的微調值不保存到database.previously只有三個的EditText值保存。 。經過微調使用沒有什麼保存到數據庫.. 這裏我想給三個編輯文本的價值觀和選擇微調項目作爲paramater到PHP文件.. 請幫我選擇的微調項目保存到數據庫中。 。使用PHP和Android
這裏是我的文件..

刀片式db.php中
<?php
define('HOST','mysql.hostinger.in');
define('USER','u449667615_user');
define('PASS','1234');
define('DB','u449667615_db');
$con = mysqli_connect(HOST,USER,PASS,DB) or die('Unable to Connect');
$salutation = $_POST['salutation'];
$fname = $_POST['fname'];
$lname = $_POST['lname'];
$mobile = $_POST['mobile'];
$sql = "insert into person (salutation,fname,lname,mobile) values ('$salutation','$fname','$lname','$mobile')";
if(mysqli_query($con,$sql)){
echo 'success';
}
else{
echo 'failure';
}
mysqli_close($con);
?>
請檢查DATABSE字段名名稱和TABEL架構。 –
表名是正確的...但微調值並沒有保存.. –
請檢查所有值在php文件中使用回聲。 –
