Zencart根据分类加背景图片

Zencart根据分类加背景图片
在我前一个处理的项目中,有个客户要求有变动的头部背景图,在zencart里要怎么去实现这一操作呢? 在我处理的问题中有两种方法,如下:


  1. 给body里加一个DIV中CLASS的值,这个CLASS值跟后加添加的分类ID值是一样的,然后用CSS样式去控制头部的背景图。如下图:(not_ID)




  1. 在后台的分类编辑里开发出一个上传图片的地方(作为背景图),之后我们根据分类来调用。如下图:



(1)       进入数据库,在categories表中加入categories_image_header字符型字段。
(2)       在806行的样子加入以下代码:
$contents[] = array('text' => '<br />' . TEXT_CATEGORIES_IMAGE_MANUAL . '(分类头部图片)' . zen_draw_input_field('categories_image_header'));
$contents[] = array('text' => '<br />' . zen_info_image($cInfo->categories_image_header, $cInfo->categories_name));
$contents[] = array('text' => '<br />' . $cInfo->categories_image_header);
(3)进入admin/categories.php
在230行左右加上以下代码:
if ($_POST['categories_image_header'] != '') {
// add image manually
$categories_image_header = $_POST['img_dir'] . $_POST['categories_image_header'];
$db->Execute("update " . TABLE_CATEGORIES . "
set categories_image_header = '" . $categories_image_header . "'
where categories_id = '" . (int)$categories_id . "'");
}
这是判断是不是有更新的内容,如果没有,不做理会;如果有,则更新。
(4)在admin/includes/modules/category_product_listing.php中的数据查询中加入c.categories_image_header
如下:
if (isset($_GET['search'])) {
$search = zen_db_prepare_input($_GET['search']);
$categories = $db->Execute("select c.categories_id, cd.categories_name, cd.categories_description, c.categories_image,
c.parent_id, c.sort_order, c.date_added, c.last_modified,
c.categories_status, c.categories_image2,c.categories_image3,c.categories_image_header
from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd
where c.categories_id = cd.categories_id
and cd.language_id = '" . (int)$_SESSION['languages_id'] . "'
and cd.categories_name like '%" . zen_db_input($search) . "%'" .
$order_by);
} else {
$categories = $db->Execute("select c.categories_id, cd.categories_name, cd.categories_description, c.categories_image,
c.parent_id, c.sort_order, c.date_added, c.last_modified,
c.categories_status, c.categories_image2,c.categories_image3,c.categories_image_header
from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd
where c.parent_id = '" . (int)$current_category_id . "'
and c.categories_id = cd.categories_id
and cd.language_id = '" . (int)$_SESSION['languages_id'] . "'" .
$order_by);
}
即可。 如果您还有什么好的方法,请共享给我,谢谢。
