PHP and MysqL Web Development的详细信息

代码实现：

PHP

4.11 book_fns.PHP文件中的函数get_book_details()

4.12 output_fns.PHP文件中的函数display_book_details()

<div class="jb51code">
<pre class="brush:PHP;">
function display_book_details($book) //输出图书详细说明
{
if(is_array($book))
{
echo "<table><tr>";
// 如果图片存在
if(@file_exists("images/". $book['isbn'] .".jpg"))
{
$size = getimagesize("images/". $book['isbn'] .".jpg");
if(($size[0] > 0) && ($size[1] > 0))
{
echo "<td><img src=\"images/". $book['isbn'] .".jpg\" style=\"border: 1px solid black\"/></td>";
}
}
echo "<td>

";
echo "

• Author:

  ";
  echo $book['author'];
  echo "

• ISBN:

  ";
  echo $book['isbn'];
  echo "

• Our Price:

  ";
  echo number_format($book['price'],2);
  echo "

• Description:

  ";
  echo $book['description'];
  echo "

</td></tr></table>";
}
else
{
echo "

The details of this book cannot be displayed at this time.

";
}
echo "

---

";
}

5、实现购物车

不使用参数的脚本只显示购物车的内容

带有参数new的脚本将添加一个物品到购物车

代码实现： 5.1 show_cart.PHP

PHP文件中的函数display_cart()

<div class="jb51code">
<pre class="brush:PHP;">
function display_cart($cart,$change = true,$images = 1) //显示购物车
{
echo "<table border=\"0\" width=\"100%\" cellspacing=\"0\">
<form action=\"show_cart.PHP\" method=\"post\">
<tr>
<th colspan=\"". (1 + $images) ."\" bgcolor=\" #cccccc\">Item
<th bgcolor=\"#cccccc\">Price
<th bgcolor=\"#cccccc\">Quantity
<th bgcolor=\"#cccccc\">Total
</tr>";
//输出购物车中每一项
foreach($cart as $isbn => $qty)
{
$book = get_book_details($isbn);
echo "<tr>";
if($images == true)
{
echo "<td align=\"left\">";
if(file_exists("images/". $isbn .".jpg"))
{
$size = getimagesize("images/". $isbn .".jpg");
if(($size[0] > 0) && ($size[1] > 1)) //图片长宽
{
echo "<img src=\"images/". $isbn .".jpg\"
style=\"border: 1px solid black\"
width=\"". ($size[0] / 3) ."\"
height=\"". ($size[1] / 3) ."\"/>";
}
}
else
echo " ";
echo "</td>";
}
echo "<td align=\"left\">
<a href=\"show_book.PHP?isbn=". $isbn ."\">". $book['title'] ." by". $book['author'] ."</td>
<td align=\"center\">\$". number_format($book['price'],2) ."</td><td align=\"center\">";

//如果允许更改数量
if ($change == true)
{
echo "<input type=\"text\" name=\"".$isbn."\" value=\"".$qty."\" size=\"3\">";
}
else
{
echo $qty;
}
echo "</td><td align=\"center\">\$".number_format($book['price']*$qty,2)."</td></tr>\n";
}

//总数
echo "<tr>
<th colspan=\"". (2 + $images) ."\" bgcolor = \"#cccccc\">
<th align = \"center\" bgcolor=\"#cccccc\">". $_SESSION['items'] ."
<th align = \"center\" bgcolor=\"#cccccc\">\$". number_format($_SESSION['total_price'],2) ."</tr>";

//保存按钮
if($change == true)
{
echo "<tr>
<td colspan = \"". (2 + $images) ."\"> </td>
<td align = \"center \">
<input type=\"hidden\" name=\"save\"value=\"true\" />
<input type = \"image\" src = \"images/save-changes.gif\" border = \" 0 \" alt = \" Save Changes \" />
</td>
<td> </td>
</tr>";
}
echo "</table>";
}

//显示没有图片，不允许更改数量的购物车
display_cart($_SESSION['cart'],0);

display_shipping(calculate_shipping_cost());

if(process_card($_POST))
