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： \themes\redbaby\library ;

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）

[html] view plain copy
<div class="index_hotOuter">
<div class="index_hotTitle">精选热销</div>
<div class="index_hotBody">
<!--{foreach from=$cat_promotion<span style="color:#ff0000;"> </span>item=goods name="promotion_foreach"}-->
<div class="index_hotBodyBox" >
<div class="hotPic"><a href="{$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 \languages\zh_cn\admin\template.PHP

打开后，找到这个位置



在最后添加

[html] view plain copy
$_LANG['template_libs']['cat_promotion'] = '分类促销商品';

这样完成了语言项添加。

3、修改 \admin\includes\lib_template.php

[php] view plain copy
/* 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
[php] view plain copy
'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：

[php] view plain copy
/* 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： \includes\lib_main.php

找到这个函数，做修改，加入你自己的东东：

[php] view plain copy
/**
* 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 \include\lib_goods.php里，函数头如下：

[php] view plain copy
/**
* 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\include\lib_main.php中还要找到这个函数，做如下添加：

[php] view plain copy
/**
* 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\template.php具体需要修改的地方见最后一行示例：

（1）

[php] view plain copy
/* 动态内容 */
$cate_goods   = array();
$brand_goods  = array();
$cat_articles = array();
$ad_positions = array();
$cate_promotion = array(); //后加

（2）

[php] view plain copy
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）

[php] view plain copy
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）

[php] view plain copy
/*------------------------------------------------------ */
//-- 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）

[php] view plain copy
/* 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\templates\template_setup.htm 这个是模板设置页面的模板文件。

(1)

[html] view plain copy
<!-- 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\templates\template_setup.htm 的下边的js脚本里，要添加如下红色的(后加的)代码

[javascript] view plain copy
<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}
[javascript] view plain copy
......
[javascript] view plain copy
/**
* 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);
}

......
[javascript] view plain copy
{/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。
