ecshop 添加自定义动态库项目详解
对于如何添加静态库项目,这个有很多人写过,我用的是ecshop 2.7.2版,这里不多说了,我这里要讲的是如何 添加自定义动态库项目.
实现在后台 模板设置页里能看到最下边红色框内多出的 动态项目库
需要修改的地方有:(csdn的源码贴出挺麻烦的, 不知道怎么用不同颜色标出,只好在添加修改的地方用 后加的字样来标出了)
1、编制好你需要添加的动态库项目文件，我在这里添加的是 cat_promotion.lbi ,放置的位置是所在模版(我这里用的模版名称是 “redbaby ” ) 的 library目录中,对应完整目录是： hemes edbabylibrary ;
我这里的该库文件内容代码如下：（注意下调用的列表对象变量这里是 $cat_promotion）
<div class="index_hotOuter">
<div class="index_hotTitle">精选热销</div>
<div class="index_hotBody">
<!--{foreach from=$cat_promotion item=goods name="promotion_foreach"}-->
<div class="index_hotBodyBox" >
<div class="hotPic"><a href="{$goods.url}"><img src="{$goods.thumb}" border="0" alt="{$goods.name|escape:html}" /></a></div>
<div class="hotName"><a href="{$goods.url}" title="{$goods.name|escape:html}">{$goods.short_name|escape:html}</a></div>
<div class="hotInfo"><span class="price02" style="color:#CC0000">{$goods.promote_price}</span></div>
</div>
<!--{/foreach}-->
</div>
<div class="index_hotMore"><a href="brand.php" target=_blank></a></div>
</div>
2 、添加语言项
找到 languageszh_cnadmin emplate.php
打开后，找到这个位置
在最后添加
$_LANG["template_libs"]["cat_promotion"] = "分类促销商品";
这样完成了语言项添加。
3、修改 adminincludeslib_template.php
/* 动态库项目 */
$dyna_libs = array(
"cat_goods",
"brand_goods",
"suppliers_goods",
"cat_articles",
"ad_position",
//我这里加上下边的预定义的动态库项目文件名
"cat_promotion" );
4、上边都做完了，然后做什么呢，关键的地方到了，我们找到前台显示页面的主php文件中，这里找到的 index.php
里面有：
/* 页面中的动态内容 */
assign_dynamic("index");
这里就是在前台页面中加载动态项目库的函数了，这个函数在哪里呢？
在这个地方： includeslib_main.php
找到这个函数，做修改，加入你自己的东东：
/**
* 获得指定页面的动态内容
*
* @access public
* @param string $tmp 模板名称
* @return void
*/
function assign_dynamic($tmp)
{
$sql = "SELECT id, number, type FROM " . $GLOBALS["ecs"]->table("template") .
" WHERE filename = "$tmp" AND type > 0 AND remarks ="" AND theme="" . $GLOBALS["_CFG"]["template"] . """;
$res = $GLOBALS["db"]->getAll($sql);
foreach ($res AS $row)
{
switch ($row["type"])
{
case 1:
/* 分类下的商品 */
$GLOBALS["smarty"]->assign("goods_cat_" . $row["id"], assign_cat_goods($row["id"], $row["number"]));
break;
case 2:
/* 品牌的商品 */
$brand_goods = assign_brand_goods($row["id"], $row["number"]);
$GLOBALS["smarty"]->assign("brand_goods_" . $row["id"], $brand_goods["goods"]);
$GLOBALS["smarty"]->assign("goods_brand_" . $row["id"], $brand_goods["brand"]);
break;
case 3:
/* 文章列表 */
$cat_articles = assign_articles($row["id"], $row["number"]);
$GLOBALS["smarty"]->assign("articles_cat_" . $row["id"], $cat_articles["cat"]);
$GLOBALS["smarty"]->assign("articles_" . $row["id"], $cat_articles["arr"]);
break;
case 5:
/* 分类下的促销商品 后加---*/
$GLOBALS["smarty"]->assign("promotion_cat_" . $row["id"], assign_cat_promotion($row["id"], $row["number"]));
break;
}
}
}
上边的这个 函数 assign_cat_promotion($row["id"], $row["number"])); 你要自己定义，用来获取后台模板设置的时候指定一些参数，我这边定义在 includelib_goods.php里，函数头如下：
/**
* 获得指定分类下的促销商品
*
* @access public
* @param integer $cat_id 分类ID
* @param integer $num 数量
* @param string $from 来自web/wap的调用
* @param string $order_rule 指定商品排序规则
* @return array
*/
function assign_cat_promotion($cat_id, $num = 0, $from = "web", $order_rule = "")
{
另外，在includelib_main.php中还要找到这个函数，做如下添加：
/**
* 替换动态模块
*
* @access public
* @param string $matches 匹配内容
*
* @return string 结果
*/
function dyna_libs_replace($matches)
{
$key = "/" . $matches[1];
if ($row = array_shift($GLOBALS["libs"][$key]))
{
$str = "";
switch($row["type"])
{
case 1:
// 分类的商品
$str = "{assign var="cat_goods" value=$cat_goods_" .$row["id"]. "}{assign var="goods_cat" value=$goods_cat_" .$row["id"]. "}";
break;
case 2:
// 品牌的商品
$str = "{assign var="brand_goods" value=$brand_goods_" .$row["id"]. "}{assign var="goods_brand" value=$goods_brand_" .$row["id"]. "}";
break;
case 3:
// 文章列表
$str = "{assign var="articles" value=$articles_" .$row["id"]. "}{assign var="articles_cat" value=$articles_cat_" .$row["id"]. "}";
break;
case 4:
//广告位
$str = "{assign var="ads_id" value=" . $row["id"] . "}{assign var="ads_num" value=" . $row["number"] . "}";
break;
case 5:
// 分类的促销商品 -------后加的
$str = "{assign var="cat_promotion" value=$cat_promotion_" .$row["id"]. "}{assign var="promotion_cat" value=$promotion_cat_" .$row["id"]. "}";
break;
}
return $str . $matches[0];
}
else
{
return $matches[0];
}
}这样结束lib_main.php的修改。
5、上边数据准备好，那要在后台的模板设置里能看到动态项目库，如这样格式：(注意下边红色框内是动态库项目调用的地方，我添加的就是 红色椭圆框内的)需要修改2个文件，一个是 admin emplate.php具体需要修改的地方见最后一行示例：
（1）
/* 动态内容 */
$cate_goods = array();
$brand_goods = array();
$cat_articles = array();
$ad_positions = array();
$cate_promotion = array(); //后加（2）
foreach ($temp_libs AS $val)
{
/* 对动态内容赋值 */
if ($val["lib"] == "cat_goods")
{
/* 分类下的商品 */
if (isset($db_dyna_libs[$val["region"]][$val["library"]]) && ($row = array_shift($db_dyna_libs[$val["region"]][$val["library"]])))
{
$cate_goods[] = array("region" => $val["region"], "sort_order" => $val["sort_order"], "number" => $row["number"], "cats"=>cat_list(0, $row["id"]));
}
else
{
$cate_goods[] = array("region" => $val["region"], "sort_order" => $val["sort_order"], "number"=>0, "cats"=>cat_list(0));
}
}
/* 分类促销产品 后加的*/
elseif ($val["lib"] == "cat_promotion")
{
/* 分类下的商品 */
if (isset($db_dyna_libs[$val["region"]][$val["library"]]) && ($row = array_shift($db_dyna_libs[$val["region"]][$val["library"]])))
{
$cate_promotion[] = array("region" => $val["region"], "sort_order" => $val["sort_order"], "number" => $row["number"], "cats"=>cat_list(0, $row["id"]));
}
else
{
$cate_promotion[] = array("region" => $val["region"], "sort_order" => $val["sort_order"], "number"=>0, "cats"=>cat_list(0));
}
}
（3）
assign_query_info();
$smarty->assign("ur_here", $_LANG["03_template_setup"]);
$smarty->assign("curr_template_file", $curr_template);
$smarty->assign("temp_options", $temp_options);
$smarty->assign("temp_regions", $temp_regions);
$smarty->assign("cate_goods", $cate_goods);
$smarty->assign("brand_goods", $brand_goods);
$smarty->assign("cat_articles", $cat_articles);
$smarty->assign("ad_positions", $ad_positions);
$smarty->assign("cate_promotion", $cate_promotion);//后加
$smarty->assign("arr_cates", cat_list(0, 0, true));
$smarty->assign("arr_brands", get_brand_list());
$smarty->assign("arr_article_cats", article_cat_list(0, 0, true));
$smarty->assign("arr_ad_positions", get_position_list());
$smarty->assign("arr_promotion", cat_list(0, 0, true));//后加
$smarty->display("template_setup.htm");（4）
/*------------------------------------------------------ */
//-- 提交模板内容设置
/*------------------------------------------------------ */
if ($_REQUEST["act"] == "setting")
{
admin_priv("template_setup");
$curr_template = $_CFG["template"];
$db->query("DELETE FROM " .$ecs->table("template"). " WHERE remarks = "" AND filename = "$_POST[template_file]" AND theme = "$curr_template"");
/* 先处理固定内容 */
foreach ($_POST["regions"] AS $key => $val)
{
$number = isset($_POST["number"][$key]) ? intval($_POST["number"][$key]) : 0;
if (!in_array($key, $GLOBALS["dyna_libs"]) AND (isset($_POST["display"][$key]) AND $_POST["display"][$key] == 1 OR $number > 0))
{
$sql = "INSERT INTO " .$ecs->table("template").
"(theme, filename, region, library, sort_order, number)".
" VALUES ".
"("$curr_template", "$_POST[template_file]", "$val", "".$_POST["map"][$key]."", "" . @$_POST["sort_order"][$key] . "", "$number")";
$db->query($sql);
}
}
/* 分类的商品 */
if (isset($_POST["regions"]["cat_goods"]))
{
foreach ($_POST["regions"]["cat_goods"] AS $key => $val)
{
if ($_POST["categories"]["cat_goods"][$key] != "" && intval($_POST["categories"]["cat_goods"][$key]) > 0)
{
$sql = "INSERT INTO " .$ecs->table("template"). " (".
"theme, filename, region, library, sort_order, type, id, number".
") VALUES (".
""$curr_template", ".
""$_POST[template_file]", "" .$val. "", "/library/cat_goods.lbi", ".
""" .$_POST["sort_order"]["cat_goods"][$key]. "", 1, "" .$_POST["categories"]["cat_goods"][$key].
"", "" .$_POST["number"]["cat_goods"][$key]. """.
")";
$db->query($sql);
}
}
}
/* 分类促销的商品 后加的*/
if (isset($_POST["regions"]["cat_promotion"]))
{
foreach ($_POST["regions"]["cat_promotion"] AS $key => $val)
{
if ($_POST["promotion"]["cat_promotion"][$key] != "" && intval($_POST["promotion"]["cat_promotion"][$key]) > 0)
{
$sql = "INSERT INTO " .$ecs->table("template"). " (".
"theme, filename, region, library, sort_order, type, id, number".
") VALUES (".
""$curr_template", ".
""$_POST[template_file]", "" .$val. "", "/library/cat_promotion.lbi", ".
""" .$_POST["sort_order"]["cat_promotion"][$key]. "", 5, "" .$_POST["promotion"]["cat_promotion"][$key].
"", "" .$_POST["number"]["cat_promotion"][$key]. """.
")";
$db->query($sql);
}
}
}
（5）
/* 对提交内容进行处理 */
$post_regions = array();
foreach ($_POST["regions"] AS $key => $val)
{
switch ($key)
{
case "cat_goods":
foreach ($val AS $k => $v)
{
if (intval($_POST["categories"]["cat_goods"][$k]) > 0)
{
$post_regions[] = array("region" => $v,
"type" => 1,
"number" => $_POST["number"]["cat_goods"][$k],
"library" => "/library/" .$key. ".lbi",
"sort_order" => $_POST["sort_order"]["cat_goods"][$k],
"id" => $_POST["categories"]["cat_goods"][$k]);
}
}
break;
case "cat_promotion": //后加
foreach ($val AS $k => $v)
{
if (intval($_POST["promotion"]["cat_promotion"][$k]) > 0)
{
$post_regions[] = array("region" => $v,
"type" => 5,
"number" => $_POST["number"]["cat_promotion"][$k],
"library" => "/library/" .$key. ".lbi",
"sort_order" => $_POST["sort_order"]["cat_promotion"][$k],
"id" => $_POST["categories"]["cat_promotion"][$k]);
}
}
break;
到此，修改完template.php文件
6、修改 admin emplates emplate_setup.htm 这个是模板设置页面的模板文件。
(1)
<!-- cateogry goods list -->
<tr>
<td colspan="6" style="background-color: #F4FBFB; font-weight: bold" align="left"><a href="javascript:;" onclick="addCatGoods(this)">[+]</a> {$lang.template_libs.cat_goods} </td>
</tr>
{foreach from=$cate_goods item=library key=lib_name}
<tr>
<td class="first-cell" align="right"><a href="javascript:;" onclick="removeRow(this)">[-]</a></td>
<td><select name="regions[cat_goods][]"><option value="">{$lang.select_plz}</option>{html_options values=$temp_regions output=$temp_regions selected=$library.region}</select></td>
<td><input type="text" name="sort_order[cat_goods][]" value="{$library.sort_order}" size="4" /></td>
<td><select name="categories[cat_goods][]"><option value="">{$lang.select_plz}</option>{$library.cats}</select></td>
<td><input type="text" name="number[cat_goods][]" value="{$library.number}" size="4" /></td>
<td></td>
</tr>
{/foreach}
<!-- cateogry promotion goods list 后加的 -->
<tr>
<td colspan="6" style="background-color: #F4FBFB; font-weight: bold" align="left"><a href="javascript:;" onclick="addCatPromotion(this)">[+]</a> {$lang.template_libs.cat_promotion} </td>
</tr>
{foreach from=$cate_promotion item=library key=lib_name}
<tr>
<td class="first-cell" align="right"><a href="javascript:;" onclick="removeRow(this)">[-]</a></td>
<td><select name="regions[cat_promotion][]"><option value="">{$lang.select_plz}</option>{html_options values=$temp_regions output=$temp_regions selected=$library.region}</select></td>
<td><input type="text" name="sort_order[cat_promotion][]" value="{$library.sort_order}" size="4" /></td>
<td><select name="promotion[cat_promotion][]"><option value="">{$lang.select_plz}</option>{$library.cats}</select></td>
<td><input type="text" name="number[cat_promotion][]" value="{$library.number}" size="4" /></td>
<td></td>
</tr>
{/foreach}
(2)在 admin emplates emplate_setup.htm 的下边的js脚本里，要添加如下红色的(后加的)代码
<script language="JavaScript">
<!--
var currTemplateFile = "{$curr_template_file}";
var selCategories = "{$arr_cates}";
var selRegions = new Array();
var selBrands = new Array();
var selArticleCats = new Array();
var selAdPositions = new Array();
var selPromotion = "{$arr_promotion}"; //后加的
{foreach from=$temp_regions item=region key=id}
selRegions[{$id}] = "{$region|escape:quotes}";
{/foreach}
{foreach from=$arr_brands item=brand key=id}
selBrands[{$id}] = "{$brand|escape:quotes}";
{/foreach}
{foreach from=$arr_article_cats item=cat key=id}
selArticleCats[{$id}] = "{$cat}";
{/foreach}
{foreach from=$arr_ad_positions item=ad_position key=id}
selAdPositions[{$id}] = "{$ad_position|escape}";
{/foreach}
{literal}
......
/**
* 增加一个分类的商品
*/
function addCatGoods(obj)
{
var rowId = rowindex(obj.parentNode.parentNode);
var table = obj.parentNode.parentNode.parentNode.parentNode;
var row = table.insertRow(rowId + 1);
var cell = row.insertCell(-1);
cell.innerHTML = "<a href="javascript:;" onclick="removeRow(this)">[-]</a>";
cell.className = "first-cell";
cell.align = "right";
cell = row.insertCell(-1);
cell.innerHTML = buildRegionSelect("regions[cat_goods][]");
cell = row.insertCell(-1);
cell.innerHTML = "<input type="text" name="sort_order[cat_goods][]" value="0" size="4" />";
cell = row.insertCell(-1);
cell.innerHTML = "<select name="categories[cat_goods][]"><option value="">" + selectPlease + "</option>" + selCategories + "</select>";
cell = row.insertCell(-1);
cell.innerHTML = "<input type="text" name="number[cat_goods][]" value="5" size="4" />";
cell = row.insertCell(-1);
}
/**
* 增加一个分类的促销商品,------后加
*/
function addCatPromotion(obj)
{
var rowId = rowindex(obj.parentNode.parentNode);
var table = obj.parentNode.parentNode.parentNode.parentNode;
var row = table.insertRow(rowId + 1);
var cell = row.insertCell(-1);
cell.innerHTML = "<a href="javascript:;" onclick="removeRow(this)">[-]</a>";
cell.className = "first-cell";
cell.align = "right";
cell = row.insertCell(-1);
cell.innerHTML = buildRegionSelect("regions[cat_promotion][]");
cell = row.insertCell(-1);
cell.innerHTML = "<input type="text" name="sort_order[cat_promotion][]" value="0" size="4" />";
cell = row.insertCell(-1);
cell.innerHTML = "<select name="promotion[cat_promotion][]"><option value="">" + selectPlease + "</option>" + selPromotion + "</select>";
cell = row.insertCell(-1);
cell.innerHTML = "<input type="text" name="number[cat_promotion][]" value="5" size="4" />";
cell = row.insertCell(-1);
}
......{/literal}
//-->
</script>到此结束，就可以实现在后台操作模板实现动态项目库的调用了。
