Question

您必须检查2个国家/地区才能设置运费。（这些值以前是通过下拉列表分配的）。这是我的PHP条件，它似乎不起作用。如果我犯了错误，有人可以帮我解释一下语法吗？

<?php
for( $y = 0; $y < count( $contentsArray ); $y++ )
{

  $itemArray = explode( ":", $contentsArray[ $y ] );

  $price = number_format( $itemArray[ 2 ] * $itemArray[ 1 ], 2 );
  $subtotal += $price;

  echo "<tr>";
  echo "<td class='item_col'>" . $itemArray[ 0 ] . "</td>";
  echo "<td class='description_col'>" . $itemArray[ 3 ] . "</td>";
  echo "<td class='quantity_col'>" . $itemArray[ 1 ] . "</td>";
  echo "<td class='price_col'>$ " . $price . "</td>";
  echo "</tr>";
}

// calculate the shipping  



if( $subtotal > 500 )
  $shipping = 0.00;

// ----这是我试图添加条件和错误的地方------

else if ( $country == "Canada" )
  $shipping = 10.00;
else if ( $country == "USA" )
  $shipping = 10.00;

// ----在我试图添加条件的地方------

否则 $ shipping = 15.00;

$shipping = number_format( $shipping, 2 );  




// calculate the tax and total for the cart
$gst = number_format( ( $subtotal + $shipping ) * 0.06, 2 );
$total = $subtotal + $shipping + $gst;

// update the totals in the db
$cartData->totals = $shipping . "|" . $gst . "|" . $total;
$updateSuccess = updateCartTotals( $merchant, $cartData );
?>

为了让我们进一步为您提供帮助，请在您的代码中添加以下两个新增内容（我在下面添加它们的确切位置）。运行它，然后在StackOverflow问题上粘贴“DEBUG”消息。

<?php
for( $y = 0; $y < count( $contentsArray ); $y++ )
{

  $itemArray = explode( ":", $contentsArray[ $y ] );

  $price = number_format( $itemArray[ 2 ] * $itemArray[ 1 ], 2 );
  $subtotal += $price;

  echo "<tr>";
  echo "<td class='item_col'>" . $itemArray[ 0 ] . "</td>";
  echo "<td class='description_col'>" . $itemArray[ 3 ] . "</td>";
  echo "<td class='quantity_col'>" . $itemArray[ 1 ] . "</td>";
  echo "<td class='price_col'>$ " . $price . "</td>";
  echo "</tr>";
}

// calculate the shipping  

// ADDITION #1
echo "DEBUG: subtotal is $subtotal;<br>DEBUG: country is $country";
if( $subtotal > 500 )
  $shipping = 0.00;
// ---- This is where I'm trying to add my condition and bugs ------

else if ( $country == "Canada" )
  $shipping = 10.00;
else if ( $country == "USA" )
  $shipping = 10.00;
// ---- Above where I'm trying to add my condition ------

// ADDITION #2
else $shipping = 15.00;
echo "DEBUG: shipping is $shipping";
