[英]How do I unset session products in shopping cart using remove button?
如何使用“刪除”按鈕取消購物車中的會話產品? 我有以下代碼; “清除購物車”正在運行,並取消了購物中所有商品的會話。 但是問題在於,“刪除”是否不會通過pid取消設置單個產品?
Php :
session_start();
$pid=$_SESSION['pid'];
function remove_product($pid){
$pid=intval($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']);
}
if($_REQUEST['command']=='delete' && $_REQUEST['pid']>0){
remove_product($_REQUEST['product1'][$pid]);
}
if($_REQUEST['command']=='clear' && isset($_REQUEST['remove'])){
unset($_SESSION['image12']);
unset($_SESSION['product1']);
unset($_SESSION['price12']);
unset($_SESSION['itemcode3']);
unset($_SESSION['sizes12']);
}
Js :
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();
}
}
HTML:
<form name="form1" method="post">
<input type="hidden" name="pid" />
<input type="hidden" name="command" />
<input type="button" class="button2" value="Clear Cart" onclick="clear_cart()" />
<a href="javascript:del(<?php echo $pid?>)">
<input type="button" class="button2" value="Remove" />
</a>
</form>
if($_REQUEST['command']=='delete' && $_REQUEST['pid']>0){
remove_product($_REQUEST['product1'][$pid]);
}
您的表單中沒有$ _REQUEST ['product1'],也許
if($_REQUEST['command']=='delete' && $_REQUEST['pid']>0){
remove_product($_REQUEST['pid']);
}
$ _REQUEST ['remove']也
if($_REQUEST['command']=='clear' && isset($_REQUEST['remove'])){
unset($_SESSION['image12']);
unset($_SESSION['product1']);
unset($_SESSION['price12']);
unset($_SESSION['itemcode3']);
unset($_SESSION['sizes12']);
}
我看不到要發送的任何$ _REQUEST ['remove']。
您的清除命令也不發送$ pid,不是必須的嗎?
實際上,clear()發送查詢字符串pid=&command=clear
