php - 语法错误 T_PAAMAYIM_NEKUDOTAYIM!

Question

购买.php:

<form action="cart.php" method="post">
<?php foreach($product['varieties'] as $variety): ?>
    <input style="width:10px; margin-left:9px; " name="price[]" type="checkbox" value="<?php echo $variety['price'] . '_' . $variety['size']; ?>"  />';
<?php end foreach; ?>
</form>

购物车.php:

list($aDoor, size)  = split('_', $_POST['price']); // line 207

if(empty($aDoor)) 
{
  echo("You didn't select any buildings.");
} 
else 
{
  echo "Sum of vlues = ".array_sum($aDoor);
}

在 cart.php 中存在以下语法错误:

syntax error, unexpected ')', expecting T_PAAMAYIM_NEKUDOTAYIM in store/cart.php on line 207

我期望在 cart.php 中独立地接收两个索引值大小和价格，这样我就可以在任何我想要的地方使用它和 CSS。我希望通过函数 list() 和 split() ，变量variety和带有价格值的$aDoor能够将这两个变量分开，以便在cart.php中的任何地方使用

帮助。

缺少$:

list($aDoor, $size) = split('_', $_POST['price']);//第207行

我认为你正在尝试做类似的事情:

<?php
$aDoor = array();
$size = array();

foreach ($_POST['price'] as $p)
{
  list($a, $b) = explode('_', $p);
  $aDoor[] = $a;
  $size[] = $b;
}

if(empty($aDoor)) 
{
  echo("You didn't select any buildings.");
} 
else 
{
  echo "Sum of vlues = ".array_sum($aDoor);
}

?>
