ecshop给分类上传图片
[版本]ecshop2.7.2
[关键词]ecshop 分类图片 功能开发
ecshop的商品分类没有对就的分类图片，如果你需要为分类添加图片，然后在前端显示，可以按以下的步骤实现这个功能：
第一步：为数据库中的ecs_category表增加一个字段，用来存储上传上来的分类图片名,这步可以直接在后台执行sql语句：
alter table ecs_category add thumb varchar(255) not null default '';
注意，如果你的ecshop表前缀不是ecs_请把ecs_换成你自已的表前缀
第二步：在admin/templates/categroy_info.html增加上传要类图片的表单：
代码如下
{if $cat_info.thumb}
{/if}
第三步：修改category.php的insert和update
在顶部增加:
代码如下define('IN_ECS', true);
require(dirname(__FILE__) . '/includes/init.php');
/***新增加的开始***/
include_once(ROOT_PATH . 'includes/cls_image.php');
$image = new cls_image($_CFG['bgcolor']);
/***新增加的结束***/
$exc = new exchange($ecs->table("category"), $db, 'cat_id', 'cat_name');
在insert段代码

//-- 商品分类添加时的处理
/*------------------------------------------------------ */
if ($_REQUEST['act'] == 'insert')
{
/* 权限检查 */
admin_priv('cat_manage');
/* 初始化变量 */

$cat['sort_order'] = !empty($_POST['sort_order']) ? intval($_POST['sort_order']) : 0;
$cat['keywords'] = !empty($_POST['keywords']) ? trim($_POST['keywords']) : '';

/*处理图片*/
$img_name = basename($image->upload_image($_FILES['thumb'],'catthumb'));

/* 入库的操作 */

在update段代码
/*------------------------------------------------------ */

/* 判断分类名是否重复 */
if ($cat['cat_name'] != $old_cat_name)
{
if (cat_exists($cat['cat_name'],$cat['parent_id'], $cat_id))
{
$link[] = array('text' => $_LANG['go_back'], 'href' => 'javascript:history.back(-1)');
sys_msg($_LANG['catname_exist'], 0, $link);
}
}
/* 判断上级目录是否合法 */
$children = array_keys(cat_list($cat_id, 0, false)); // 获得当前分类的所有下级分类
if (in_array($cat['parent_id'], $children))
{
/* 选定的父类是当前分类或当前分类的下级分类 */
$link[] = array('text' => $_LANG['go_back'], 'href' => 'javascript:history.back(-1)');
sys_msg($_LANG["is_leaf_error"], 0, $link);
}
if($cat['grade'] > 10 || $cat['grade'] < 0)
{
/* 价格区间数超过范围 */
$link[] = array('text' => $_LANG['go_back'], 'href' => 'javascript:history.back(-1)');
sys_msg($_LANG['grade_error'], 0, $link);
}
$dat = $db->getRow("SELECT cat_name, show_in_nav FROM ". $ecs->table('category') . " WHERE cat_id = '$cat_id'");
/* 处理图片 */
$img_name = basename($image->upload_image($_FILES['thumb'],'catthumb'));
if($img_name) $cat['thumb'] = $img_name;
if ($db->autoExecute($ecs->table('category'), $cat, 'UPDATE', "cat_id='$cat_id'"))
{
if($cat['cat_name'] != $dat['cat_name'])
{
//如果分类名称发生了改变
$sql = "UPDATE " . $ecs->table('nav') . " SET name = '" . $cat['cat_name'] . "' WHERE ctype = 'c' AND cid = '" . $cat_id . "' AND type = 'middle'";
$db->query($sql);
}
if($cat['show_in_nav'] != $dat['show_in_nav'])
{
//是否显示于导航栏发生了变化
if($cat['show_in_nav'] == 1)
{
//显示
$nid = $db->getOne("SELECT id FROM ". $ecs->table('nav') . " WHERE ctype = 'c' AND cid = '" . $cat_id . "' AND type = 'middle'");
if(empty($nid))
{
//不存在
$vieworder = $db->getOne("SELECT max(vieworder) FROM ". $ecs->table('nav') . " WHERE type = 'middle'");
$vieworder += 2;
$uri = build_uri('category', array('cid'=> $cat_id), $cat['cat_name']);

}
else
{
$sql = "UPDATE " . $ecs->table('nav') . " SET ifshow = 1 WHERE ctype = 'c' AND cid = '" . $cat_id . "' AND type = 'middle'";
}
$db->query($sql);
}
else
{
//去除
$db->query("UPDATE " . $ecs->table('nav') . " SET ifshow = 0 WHERE ctype = 'c' AND cid = '" . $cat_id . "' AND type = 'middle'");
}
}
//更新首页推荐
insert_cat_recommend($cat['cat_recommend'], $cat_id);
/* 更新分类信息成功 */
clear_cache_files(); // 清除缓存
admin_log($_POST['cat_name'], 'edit', 'category'); // 记录管理员操作
/* 提示信息 */
$link[] = array('text' => $_LANG['back_list'], 'href' => 'category.php?act=list');
sys_msg($_LANG['catedit_succed'], 0, $link);
}
}
然后再增加一个删除分类图片的方法
/*------------------------------------------------------ */
//-- 删除品牌图片
/*------------------------------------------------------ */
elseif ($_REQUEST['act'] == 'drop_thumb')
{
/* 权限判断 */
admin_priv('cat_manage');
$cat_id = isset($_GET['id']) ? intval($_GET['id']) : 0;
/* 取得logo名称 */
$sql = "SELECT thumb FROM " .$ecs->table('category'). " WHERE cat_id = '$cat_id'";
$thumb_name = $db->getOne($sql);
if (!empty($thumb_name))
{
@unlink(ROOT_PATH . DATA_DIR . '/catthumb/' .$thumb_name);
$sql = "UPDATE " .$ecs->table('category'). " SET thumb = '' WHERE cat_id = '$cat_id'";
$db->query($sql);
}
$link= array(array('text' => '编辑商品分类', 'href' => 'category.php?act=edit&cat_id=' . $cat_id), array('text' =>'商品分类列表', 'href' => 'category.php?act=list'));
sys_msg('删除商品分类小图成功', 0, $link);
}
