文章列表页主要是给某个分类显示文章列表用的。
当前页可用的变量有`$category`,这个变量是一个模型对象,表示当前分类,取值时可以直接把它当成数组用。
[TOC]
## 输出`$category`内部的值
```
{$category.id} <!--输出分类 id-->
{$category.parent_id} <!--输出分类父级分类 id-->
{$category.name} <!--输出分类名称-->
{$category.description} <!--输出分类描述-->
{$category.seo_title} <!--输出分类seo标题-->
{$category.seo_keywords} <!--输出分类 seo 关键字-->
{$category.seo_description} <!--输出分类 seo 描述-->
```
以上的值也可以当成 php 变量直接输出,这里只演示一下怎么输出 id 属性
```
<php>
echo $category['id']; /*输出分类 id*/
</php>
```
## 显示分类缩略图
文章分类缩略图是保存分类的 more 字段中
```
<!--先判断缩略图是否设置了-->
<notempty name="category.more.thumbnail">
<img src="{:cmf_get_image_url($category.more.thumbnail)}"/>
</notempty>
```
cmf_get_image_url方法是用来把缩略图的相对路径转化为可访问 url 的。
## 当前分类的文章列表制作
~~~
<php>
$where=[
'post.create_time'=>['egt',0]
];
</php>
<portal:articles item="vo" where="$where" order="post.create_time DESC" page="10"
relation="categories"
categoryIds="$category.id"
returnVarName="articles_data">
<div class="list-boxes">
<h2><a href="{:cmf_url('portal/Article/index',array('id'=>$vo['id'],'cid'=>$category['id']))}">{$vo.post_title}</a>
</h2>
<p>{$vo.post_excerpt}</p>
<div>
<div class="pull-left">
<div class="list-actions">
<a href="javascript:;"><i class="fa fa-eye"></i><span>{$vo.post_hits}</span></a>
<a href="{:url('portal/Article/doLike',array('id'=>$vo['id']))}"
class="js-count-btn"><i class="fa fa-thumbs-up"></i><span class="count">{$vo.post_like}</span></a>
<a href="{:url('user/Favorite/add',array('id'=>$vo['id'],'cid'=>$category['id']))}"
class="js-favorite-btn"
data-id="{$vo.id}"
data-table="portal_post"
data-title="{:base64_encode($vo.post_title)}"
data-url="{:cmf_url_encode('portal/Article/index',array('id'=>$vo['id'],'cid'=>$category['id']))}"
>
<i class="fa fa-star-o"></i>
</a>
</div>
</div>
<a class="btn btn-warning btn-sm pull-right"
href="{:cmf_url('portal/Article/index',array('id'=>$vo['id'],'cid'=>$category['id']))}">查看更多</a>
</div>
</div>
</portal:articles>
<ul class="pagination">
<page/>
</ul>
~~~
## 制作当前分类SEO
```
<head>
<title>{$category.name} {$category.seo_title} {$site_info.site_name|default=''}</title>
<meta name="keywords" content="{$category.seo_keywords},{$site_info.site_seo_keywords|default=''}"/>
<meta name="description" content="{$category.seo_description},{$site_info.site_seo_description|default=''}">
<!--省略...-->
</head>
```
## 制作当前分类的面包屑
```
<ol class="breadcrumb">
<li><a href="__ROOT__/">首页</a></li>
<portal:breadcrumb cid="category.id" self="false">
<li><a href="{:url('portal/List/index',['id'=>$vo['id']])}">{$vo.name}</a></li>
</portal:breadcrumb>
<li class="active">{$category.name}</li>
</ol>
```
## 创建文章列表模板
在`public/themes/quick_start/portal`目录下创建`list.html`文件,内容如下:
```
<!DOCTYPE html>
<html>
<head>
<title>{$category.name} {$category.seo_title} {$site_info.site_name|default=''}</title>
<meta name="keywords" content="{$category.seo_keywords},{$site_info.site_seo_keywords|default=''}"/>
<meta name="description" content="{$category.seo_description},{$site_info.site_seo_description|default=''}">
<include file="public@head"/>
</head>
<body class="body-white">
<include file="public@nav"/>
<div class="container">
<h2>{$category.name}</h2>
<div class="row">
<div class="col-md-9">
<div class="">
<php>
$where=[
'post.create_time'=>['egt',0]
];
</php>
<portal:articles item="vo" where="$where" order="post.create_time DESC" page="10"
relation="categories"
categoryIds="$category.id"
returnVarName="articles_data">
<div class="list-boxes">
<h2><a href="{:cmf_url('portal/Article/index',array('id'=>$vo['id'],'cid'=>$category['id']))}">{$vo.post_title}</a>
</h2>
<p>{$vo.post_excerpt}</p>
<div>
<div class="pull-left">
<div class="list-actions">
<a href="javascript:;"><i class="fa fa-eye"></i><span>{$vo.post_hits}</span></a>
<a href="{:url('portal/Article/doLike',array('id'=>$vo['id']))}"
class="js-count-btn"><i class="fa fa-thumbs-up"></i><span class="count">{$vo.post_like}</span></a>
<a href="{:url('user/Favorite/add',array('id'=>$vo['id'],'cid'=>$category['id']))}"
class="js-favorite-btn"
data-id="{$vo.id}"
data-table="portal_post"
data-title="{:base64_encode($vo.post_title)}"
data-url="{:cmf_url_encode('portal/Article/index',array('id'=>$vo['id'],'cid'=>$category['id']))}"
>
<i class="fa fa-star-o"></i>
</a>
</div>
</div>
<a class="btn btn-warning btn-sm pull-right"
href="{:cmf_url('portal/Article/index',array('id'=>$vo['id'],'cid'=>$category['id']))}">查看更多</a>
</div>
</div>
</portal:articles>
</div>
<ul class="pagination">
<page/>
</ul>
</div>
<div class="col-md-3">
</div>
</div>
</div>
<include file="public@footer"/>
<include file="public@scripts"/>
</body>
</html>
```
## 添加模板配置文件
在`public/themes/quick_start/portal`目录下创建`list.json`文件,内容如下:
```
{
"name": "文章列表页",
"action": "portal/List/index",
"description": "文章列表模板文件",
"order": 10.0,
"more": {
"vars": {
},
"widgets": {
}
}
}
```
## 更新模板
至此门户文章列表模板制作完成。
