兩種提交按鈕的類型'圖像'

Question

我有一個PHP形式的兩個提交按鈕類型'圖像'。 我如何知道哪個按鈕被點擊？

代碼：

<?php 

echo (" 

    <form action='WijzigSession.php' method='POST'> 
    <td><input class= 'nummers' type='number' name='aantal' value=".$_SESSION['producten'][$i]['aantal']." min='1' max='20'> 
    <input name='refresh' class='buttons' type='image' src='img/refresh.png'</a> 
    <input name='delete' class='buttons' type='image' src='img/delete.png'</a> 
    <input type='hidden' name='id' value='$i'> 
    </form></td> 
    <td>&euro; ".$_SESSION['producten'][$i]['prijs']."</td> 

    "); 

?>

試試看：

if(isset($_POST['refresh_x'])) { //you can potentially even check for '$_POST['refresh_y']' 
    // refresh is clicked 
} 

if(isset($_POST['delete_x'])) { 
    // delete is clicked 
}
