點擊「刪除按鈕」時，我無法從購物車中刪除商品？

Question

我有購物車頁面，但問題是我無法從購物車中刪除物品，當點擊remove button？

1）我想通過基於產品pid的產品從購物車中刪除商品？
2）當我回顯$pid=intval($pid);它顯示PID？在購物車頁面上？

產品頁面

session_start(); 
$id=$_REQUEST['id']; 
$_SESSION['pid1']= $_POST['ids']; //Product ID// 

<form method="post"> 
<input type="hidden" name="ids" value="<?php echo $id?>" /> 
</form> 

<input type="submit" class="button1" name="addtocart" value="Add To Cart" 
/> 

</form> 

購物車頁面

session_start(); 
$pid=$_SESSION['pid1']; 

if($_REQUEST['command']=='delete' && $pid>0){ 
    $pid=intval($pid); 
    $max=count($_SESSION['product1']); 
    for($i=0;$i<$max;$i++){ 
    if($pid==$_SESSION['product1'][$i]['pid']){ 
     unset($_SESSION['product1'][$i]); 
     break; 
    } 
    } 
    $_SESSION['product1']=array_values($_SESSION['product1']); 
} 


<form name="form1" method="post"> 
<input type="hidden" name="pid" /> 
<input type="hidden" name="command" /> 

<a href="javascript:del(<?php echo $pid?>)"> 
<input type="button" class="button2" value="Remove" /> 
</a> 

購物車頁面的JavaScript

<script language="javascript"> 
function del(pid){ 
if(confirm('Do you really mean to delete this item')){ 
document.form1.pid.value=pid; 
document.form1.command.value='delete'; 
document.form1.submit(); 
} 
} 

function clear_cart(){ 
if(confirm('This will empty your shopping cart, continue?')){ 
document.form1.command.value='clear'; 
document.form1.submit(); 
} 
}

請修改您的形式： -

<form name="form1" method="post">  
    <input type="hidden" name="pid" value="<?php echo $pid?>" /> 
    <input type="hidden" name="command" value="delete" /> 
    <input type="button" class="button2" value="Remove" onclick="javascript:del(<?php echo $pid?>)" /> 
    </form>
