本文主要是介绍[thinkPHP5项目实战_29]前台首页和文章搜索功能完善,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
1. 首页功能
首页展示出所有文章,因此需要单独处理,首先在后台将首页的栏目删除,并将首页栏目下的文章移到其他栏目或者删除;
在头部导航header.html单独对首页进行处理;
<div class="blog-masthead"><div class="container"><nav class="blog-nav"><a class="blog-nav-item" href="{:url('Index/index')}">首页</a>{volist name="navres" id="vo"}<a class="blog-nav-item" href="{if condition="$vo['type'] eq 0"}{:url('lists/index',array('cateid'=>$vo['ID']))}{else /}{:url('guest/index',array('cateid'=>$vo['ID']))}{/if}">{$vo.catename}</a>{/volist}</nav></div>
</div>
点击首页导航通过index.php控制器进行处理:
获取所有的文章并通过联表查询每篇文章对应的栏目名:
<?php
namespace app\index\controller;
class Index extends Basic
{public function index(){$artres= \think\Db::name('article')->alias('a')->join('cate c','c.ID = a.cateid','LEFT')->field('a.artid,a.title,a.pic,a.time,a.desc,a.click,a.keywords,c.catename')->order('a.artid desc')->paginate(2);$this->assign('artres',$artres);return $this->fetch();}
}
首页模板Index.html赋值,与文章列表模板赋值一样:
<body><!-- 引入头部 -->{include file="Public/header" /}<div class="container"><div class="row"><div class="col-sm-8 blog-main">{volist name="artres" id="vo"}<div class="post multi-post cate2 auth1"><h4 class="post-date">{$vo.time|date="Y年m月d日",###}</h4><h2 class="post-title"><a href="{:url('Article/index',array('artid'=>$vo['artid']))}">{$vo.title}</a></h2><div class="post-body"><p>描述:{$vo.desc}</p>{if condition="$vo['pic'] neq ''"} <p style="text-indent: 0em;"><a title="" target="_self" href="{:url('Article/index',array('artid'=>$vo['artid']))}"><img src="__PUBLIC__{$vo.pic}"/></a></p>{/if}</div><h5 class="post-tags">关键词: <span class="tags"><?php$arr=explode(',', $vo['keywords']);foreach ($arr as $k => $v) {echo "<a href='http://localhost/test/tp5/Public/index.php/index/Tags/index/tags/$v'>$v</a>";echo ' ';}?></span></h5><h6 class="post-footer">发布:渣渣 | 分类:{$vo.catename} | 评论:6 | 浏览:{$vo.click} | <a href="{:url('Article/index',array('artid'=>$vo['artid']))}">阅读全文 > </a></h6></div>{/volist}<div class="post pagebar">{$artres->render()}</div></div><div class="col-sm-3 col-sm-offset-1 blog-sidebar"><div class="sidebar-module sidebar-module-inset"><h4>文章搜索:</h4><form method="post" action="{:url('Search/index')}"><input type="text" name="keywords" id="edtSearch" size="12" /> <input type="submit" value="提交" id="btnPost" /></form></div></div></div></div>{include file="public/footer" /}
</body>
2.文章搜索
文章搜索是通过搜索文章标题实现;
将搜索框放在每个页面的侧边栏上,将搜素的关键词在数据中对每篇文章题目进行比对,返回响应的文章信息列表;
搜索框:
<div class="sidebar-module sidebar-module-inset"><h4>文章搜索:</h4><form method="post" action="{:url('Search/index')}"><input type="text" name="keywords" id="edtSearch" size="12" /> <input type="submit" value="提交" id="btnPost" /></form></div>
对应的Search控制器方法为:
<?php
namespace app\index\controller;
class Search extends Basic
{public function index(){$keywords=input('keywords');//获取搜索关键词if($keywords){$map['title'] = ['like','%'.$keywords.'%'];//关键词模糊搜索语句$seares=\think\Db::name('article')->where($map)->order('artid desc')->paginate(2);//查询和分页$this->assign('seares',$seares);//模板赋值$this->assign('keywords',$keywords);}else{$this->assign('keywords','没有关键词');//没有关键词的情况处理$this->assign('seares',null);}return $this->fetch('search');}
}
Search.html进行模板赋值:
需要对没有文章的情况进行判断
<body>{include file="Public/header" /}<div class="container"><div class="row"><div class="col-sm-8 blog-main"><div class="post single-post cate0 auth0"><h4 class="post-date"></h4><h2 class="post-title">关键词:{$keywords}</h2><div class="post-body"> {if condition="$seares neq ' '"}{volist name="seares" id="vo"}<div><br/><font size="+0.5"><a target="_blank" href="{:url('article/index',array('artid'=>$vo['artid']))}">题目:{$vo.title}</a></font><br/>描述:{$vo.desc}<br/><br/></div>{/volist}{else /}没有搜索结果!{/if}</div></div></div></div>{include file="Public/footer" /}
</body>
