zencart_magiczoom

mod_zencart_magiczoom使用

 

一、复制相应文件到相应目录。

二、安装sql文件。

三、按照正确命名上传商品图片，一般需要中图跟大图。

四、程序运行时会在images目录下创建magicthumbs目录，并根据商品图片，每个商品自动生成两张图片用于前台显示
，生成图片的尺寸可以在后台设置，前台也可以用CSS控制显示。

五、中图输出模板在文件magiczoom.module.core.class.php中大约130行处修改。

六、去掉顶部标题，修改文件magiczoom.module.core.class.php，去掉$title变量：

return "<a{$link} class="MagicZoom"{$title} id="MagicZoomImage{$id}" ，删除红色字体。

 

 

zencart 产品图片分析

 

数据库存放格式

数据表中只保留一个字段存储图片信息，保存从根目录下images目录为起点的路径名（不包含images），如a.jpg，a/b.jpg，以下称为原图。

中图和大图存放位置及命名格式

中图与大图分别位于images/medium和images/large，图片名为原图片名加中图后缀或大图后缀，如a_mid.jpg,a_lag.jpg

附加图片存放位置及命名格式

附加图片跟原图片相同目录，原图如果在images目录下，则附加图片命名格式为原图名加任意字符（后缀必须一样），原图如果在images下的子目录下，则附加图片命名格式为原图名加下划线加任意字符，同样，后缀名必须一样。
附加图中图大图位于images/medium和images/large下，目录结枸必须和原图一样，命名格式为附加图名加中图后缀或大图后缀。

取出原图中图、大图路径

$products_image_extension = substr($products_image, strrpos($products_image, '.'));
$products_image_base = str_replace($products_image_extension, '', $products_image);
$products_image_medium = $products_image_base . IMAGE_SUFFIX_MEDIUM . $products_image_extension;
$products_image_large = $products_image_base . IMAGE_SUFFIX_LARGE . $products_image_extension;

if (!file_exists(DIR_WS_IMAGES . 'medium/' . $products_image_medium)) {
  $products_image_medium = DIR_WS_IMAGES . $products_image;
} else {
  $products_image_medium = DIR_WS_IMAGES . 'medium/' . $products_image_medium;
}

Magic Zoom 使用说明

 

引入主要文件

<link type="text/css" rel="stylesheet" href="magiczoom.css"/>
<script type="text/javascript" src="magiczoom.js"></script>

结构

　　单图片结构（中图+大图）
　　<a href="big.jpg" class="MagicZoom"><img src="small.jpg"/></a>
　　（其中class="MagicZoom"为关键项）

　　多图片结构（小图+中图+大图）
　　主图：<a href="dbig.jpg" class="MagicZoom" id="rabbit"><img src="small.jpg"></a>
　　附加图：<a href="addimg_big.jpg" rel="zoom-id:rabbit" rev="addimg_mid.jpg"><img src="addimg_small.jpg"/></a>
　　　　　　<a href="addimg2_big.jpg" rel="zoom-id:rabbit" rev="addimg2_mid.jpg"><img src="addimg2_small.jpg"/></a>
　　　　　　（为主图添加id属性，附加图添加rev指向中图，通过rel="zoom-id:rabbit"确立联系）

参数设置

为rel属性设置参数列表，如
<a href="big.jpg" class="MagicZoom" rel="zoom-118px; zoom-height:118px"><img src="small.jpg"/></a>

特例：自定义显示框位置
<a href="big.jpg" class="MagicZoom" id="elephant" rel="zoom-position: custom><img src="small.jpg"/></a>
<div id="elephant-big"></div>

样式设置

在magiczoom.css添加自定义样式

设置显示框样式
.MagicZoomBigImageCont {
border: none;
}
设置抓图区样式
.MagicZoomPup {
border: 2px solid #658EC2;
background: #658EC2 url(dotted.png);
cursor: move;
}
