关于OpenCart的一个小建议

OpenCart是一套老牌的开源自由B2C电商系统，最近watch了其托管在在github上的项目，发现还是很活跃的，每天都有人反馈bug。

初步的看一下，它是支持在后台管理多个店铺的，而且可以同一个商品在不同店铺有不同的价格；店铺之间可以绑定不同的域名。这是一个比较有特色的地方。

但查看它的代码，就发现多年来改动很小，在代码的分工上，没有进化的感觉。

大量本该由视图来进行构造的数据如语言、链接、当前路径等，都放到控制器中，

像前台登录页面：

<code><span>$data</span><span>[</span><span>'breadcrumbs'</span><span>]</span> = <span>array</span><span>();</span><span>$data</span><span>[</span><span>'breadcrumbs'</span><span>][]</span> = <span>array</span><span>(</span><span>'text'</span> =&gt; <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'text_home'</span><span>),</span><span>'href'</span> =&gt; <span>$this</span>-&gt;url-&gt;<span>link</span><span>(</span><span>'common/home'</span><span>)</span><span>);</span><span>$data</span><span>[</span><span>'breadcrumbs'</span><span>][]</span> = <span>array</span><span>(</span><span>'text'</span> =&gt; <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'text_account'</span><span>),</span><span>'href'</span> =&gt; <span>$this</span>-&gt;url-&gt;<span>link</span><span>(</span><span>'account/account'</span><span>,</span><span>''</span><span>,</span><span>'SSL'</span><span>)</span><span>);</span><span>$data</span><span>[</span><span>'breadcrumbs'</span><span>][]</span> = <span>array</span><span>(</span><span>'text'</span> =&gt; <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'text_login'</span><span>),</span><span>'href'</span> =&gt; <span>$this</span>-&gt;url-&gt;<span>link</span><span>(</span><span>'account/login'</span><span>,</span><span>''</span><span>,</span><span>'SSL'</span><span>)</span><span>);</span><span>$data</span><span>[</span><span>'heading_title'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'heading_title'</span><span>);</span><span>$data</span><span>[</span><span>'text_new_customer'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'text_new_customer'</span><span>);</span><span>$data</span><span>[</span><span>'text_register'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'text_register'</span><span>);</span><span>$data</span><span>[</span><span>'text_register_account'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'text_register_account'</span><span>);</span><span>$data</span><span>[</span><span>'text_returning_customer'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'text_returning_customer'</span><span>);</span><span>$data</span><span>[</span><span>'text_i_am_returning_customer'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'text_i_am_returning_customer'</span><span>);</span><span>$data</span><span>[</span><span>'text_forgotten'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'text_forgotten'</span><span>);</span><span>$data</span><span>[</span><span>'entry_email'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'entry_email'</span><span>);</span><span>$data</span><span>[</span><span>'entry_password'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'entry_password'</span><span>);</span><span>$data</span><span>[</span><span>'button_continue'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'button_continue'</span><span>);</span><span>$data</span><span>[</span><span>'button_login'</span><span>]</span> = <span>$this</span>-&gt;language-&gt;get<span>(</span><span>'button_login'</span><span>);</span><span>if</span><span>(</span><span>isset</span><span>(</span><span>$this</span>-&gt;error<span>[</span><span>'warning'</span><span>]))</span> {

            <span>$data</span><span>[</span><span>'error_warning'</span><span>]</span> = <span>''</span><span>;</span>
        }

        <span>$data</span><span>[</span><span>'action'</span><span>]</span> = <span>$this</span>-&gt;url-&gt;<span>link</span><span>(</span><span>'account/login'</span><span>,</span><span>''</span><span>,</span><span>'SSL'</span><span>);</span><span>$data</span><span>[</span><span>'register'</span><span>]</span> = <span>$this</span>-&gt;url-&gt;<span>link</span><span>(</span><span>'account/register'</span><span>,</span><span>''</span><span>,</span><span>'SSL'</span><span>);</span><span>$data</span><span>[</span><span>'forgotten'</span><span>]</span> = <span>$this</span>-&gt;url-&gt;<span>link</span><span>(</span><span>'account/forgotten'</span><span>,</span><span>''</span><span>,</span><span>'SSL'</span><span>);</span></code>

相当累赘，其实在现有框架特性下，完全可以放到视图文件中去的。

在视图文件的头部：

<code><span><?php </span><span>$lang</span> = <span>$this</span>-&gt;registry-&gt;get<span>(</span><span>'language'</span><span>);</span><span>//加载语言包管理对象</span><span>$url</span> = <span>$this</span>-&gt;registry-&gt;get<span>(</span><span>'url'</span><span>);</span><span>//加载url对象</span><span>$this</span>-&gt;language<span>(</span><span>'common/footer'</span><span>);</span><span>//载入语言包</span><span>?&gt;</span>
<footer>
  <div>class=<span>"container"</span>&gt;
    <div>class=<span>"row"</span>&gt;
      ?php <span>if</span><span>(</span><span>$informations</span><span>)</span> { <span>?&gt;</span>
      <div>class=<span>"col-sm-3"</span>&gt;
        <h5>?php <span>echo</span><span>$lang</span>-&gt;get<span>(</span><span>'text_information'</span><span>);</span><span>?&gt;</span>
</h5>
        <ul>class=<span>"list-unstyled"</span>&gt;
          ?php <span>foreach</span><span>(</span><span>$informations</span><span>as</span><span>$information</span><span>)</span> { <span>?&gt;</span>
          <li><a href="&lt;span">"<?php echo </span><span>$information</span><span>['href']; ?&gt;"</span>&gt;?php <span>echo</span><span>$information</span><span>[</span><span>'title'</span><span>];</span><span>?&gt;</span></a></li>
          ?php } <span>?&gt;</span>
        </ul>
      </div>
      ?php } <span>?&gt;</span><p>这样控制器中就不用再管这种无聊的事情，而集中精力负责业务逻辑和核心数据的调用了。</p>
