想要回显所有商品名称产品。只有最后添加的项目才会被回显。不是全部。

问题描述：

I am coding a shopping cart. This is just part of the code. I want to be able to echo all item names in the cart. Only allows me to echo only the last added item name.

<?php
if(!empty($_SESSION["shopping_cart"]))
{$total = 0;foreach($_SESSION["shopping_cart"] as $keys => $values)
{
?>
<tr>
<td><?php echo $values["item_name"]; ?></td>
<td><?php echo $values["item_quantity"]; ?></td>
<td>$ <?php echo $values["item_price"]; ?></td>
<td>$ <?php echo number_format($values["item_quantity"] * $values["item_price"], 2);?></td>
<td><a href="index.php?action=delete&id=<?php echo $values["item_id"]; ?>"><span class="text-danger">Remove</span></a></td>
</tr>
<?php
$total = $total + ($values["item_quantity"] * $values["item_price"]);}
?>
<?php 
echo($values["item_name"]);
?>

我正在编写购物车。这只是代码的一部分。我希望能够回显购物车中的所有商品名称。只允许我回显最后添加的项目名称。 p>

 ＆lt;？php 
if（！empty（$ _ SESSION [“shopping_cart”]））
 {$ total = 0; foreach（$ _ SESSION [“shopping_cart”] 如$ keys =＆gt; $ values）
 {
？＆gt; 
＆lt; tr＆gt; 
＆lt; td＆gt;＆lt;？php echo $ values [“item_name”];  ？＆gt;＆lt; / td＆gt; 
＆lt; td＆gt;＆lt;？php echo $ values [“item_quantity”];  ？＆gt;＆lt; / td＆gt; 
＆lt; td＆gt; $＆lt;？php echo $ values [“item_price”];  ？＆gt;＆lt; / td＆gt; 
＆lt; td＆gt; $＆lt;？php echo number_format（$ values [“item_quantity”] * $ values [“item_price”]，2）;？＆gt;＆lt; / td＆gt; 
＆lt;  ; td＆gt;＆lt; a href =“index.php？action = delete＆amp; id =＆lt;？php echo $ values [”item_id“];？＆gt;”＆gt;＆lt; span class =“text-danger”＆gt; 删除＆lt; / span＆gt;＆lt; / a＆gt;＆lt; / td＆gt; 
＆lt; / tr＆gt; 
＆lt;？php 
 $ total = $ total +（$ values [“item_quantity”] * $ values [“item_price”]  ）;} 
？＆gt; 
＆lt;？php 
echo（$ values [“item_name”]）;

EDIT :

If you want to echo outside your foreach, you can push your data in an array, and echo after.

echo don't like array. Use a var_dump or stringify your data.

<?php
if(!empty($_SESSION["shopping_cart"])) {
     $total = 0;
     $return = [];
     foreach($_SESSION["shopping_cart"] as $keys => $values) {
 ?>
        <tr>
            <td><?php echo $values["item_name"]; ?></td>
            <td><?php echo $values["item_quantity"]; ?></td>
            <td>$ <?php echo $values["item_price"]; ?></td>
            <td>$ <?php echo number_format($values["item_quantity"] * $values["item_price"], 2);?></td>
            <td><a href="index.php?action=delete&id=<?php echo $values["item_id"]; ?>"><span class="text-danger">Remove</span></a></td>
        </tr>
<?php
        $total = $total + ($values["item_quantity"] * $values["item_price"]); 
        $return[] = $values["item_name"];
    }

    var_dump($return);
?>

Previous Answer :

You have to put your echo in your foreach.

With your echo outside the foreach, $values takes only the last value.

Like this :

<?php
if(!empty($_SESSION["shopping_cart"])) {
     $total = 0;
     foreach($_SESSION["shopping_cart"] as $keys => $values) {
 ?>
        <tr>
            <td><?php echo $values["item_name"]; ?></td>
            <td><?php echo $values["item_quantity"]; ?></td>
            <td>$ <?php echo $values["item_price"]; ?></td>
            <td>$ <?php echo number_format($values["item_quantity"] * $values["item_price"], 2);?></td>
            <td><a href="index.php?action=delete&id=<?php echo $values["item_id"]; ?>"><span class="text-danger">Remove</span></a></td>
        </tr>
<?php
        $total = $total + ($values["item_quantity"] * $values["item_price"]); 
        echo($values["item_name"]);
    }
?>
