我已經做了一個PHP頁面,將形成一個窗體併發布信息給自己。然後我用它創建一個對象,我通過一個方法來運行,我想返回/回顯一個字符串,這是我的代碼。試圖回聲的方法PHP的值
<?php
include_once 'checkLogin.php';
$action='';//this will store what the user wants to do
if(isset($_GET['savings'])){$action='save';}
if(isset($_GET['depreciation'])){$action='deprec';}
$time=$_POST['time'];//get the values from the form below
$interest=$_POST['interest'];
$InitialSum=$_POST['InitialSum'];
//depreciation and savings can be done on the same page
class Information{
function __construct($time,$interest,$InitialSum){
$this->time=$time;
$this->interest=$interest;
$this->InitialSum=$InitialSum;
}
function CalcSave(){
$totalAmt=$InitialSum*($interest*100);//the total amount, this will count as one year
for ($x=0;$x<$time;$x++){//therefore this should only do 1 less than the total
$totalAmt=($interest*100)*$totalAmmt;//after another year
}
return'After '.$time.' years your savings will be worth '.$totalAmt.'.';
}
function CalcDeprec(){
$totalAmt=$InitialSum*$interest;
for ($x=0;$x<$time;$x++){//therefore this should only do 1 less than the total
$totalAmt=$interest*$totalAmmt;//after another year
}
return 'After'.$time.'years your asset will be worth '.$totalAmt.'.';
}
}
?>
<!DOCTYPE HTML>
<html>
<body>
<form name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" >
Initial Amount: <input type="number" name="InitialSum"><br>
Interest: <input type="number" name="interest"><br>
How long: <input type='number' name='time'><br>
<input type="submit">
</form>
<p>
<?php
$user=new Information($time,$interest,$InitialSum);//this creates the user object
if ($action=='save'){
$user->CalcSave();//this will run the method since user is the object
echo $result;
}
if ($action=='deprec'){
$user->CalcDeprec();
echo $result;
}
?>
</p>
</body>
</html>
,如果去到不同的網頁,但最好我想這回顯到頁面上,我不介意。我沒有從它得到任何錯誤,我不是非常有經驗的OOP在PHP中。 編輯我試過$result = $user->CalcSave(); echo $result;
和
echo $user->CalcSave();
,但它在頁面的末尾重新加載相同的頁面而不
?action=depreciation
,並沒有什麼迴應。
