ECshop--导航栏模块细究

时间：2021-01-08 13:59:21

花了一下午的时间，总算解决了。



本来想在前台界面上分析看看ecshop导航栏设置，在浏览器里面是定位到了“nav-manu”下面，然后子目录是在m_left下可以看到是动态生成一系列的ul，li标签来设置导航栏的，然后打开源码，因为主界面是由index.dwt布局完成的

所以可以在其中发现

<strong><!-- #BeginLibraryItem "/library/page_header.lbi" --><!-- #EndLibraryItem --></strong>

这一行代码，因为dwt文件的缘故，注释可以忽略，然后进入

/library/page_header.lbi

文件下，找到nav-menu标签，原始代码真是够乱的，对于有强迫症的我来说，必须得重新排版下

<strong><div class="m_left">

		  <ul>

				<li>

					<a href="../index.php"

						{if $navigator_list.config.index eq 1} class="cur"{/if}>

							{$lang.home}{$lang.home}{$smarty.foreach.nav_middle_list.last}

					</a>

				</li>

				{foreach name=nav_middle_list from=$navigator_list.middle item=nav}

				{if $smarty.foreach.nav_middle_list.last}

						<li>

							<a href="{$nav.url}"

								{if $nav.opennew eq 1}

									target="_blank"

								{/if}

									{$nav.name}

							</a>

						</li>

				<!-- {else} -->

				<li>

					<a href="{$nav.url}" 

						<!-- {if $nav.opennew eq 1} -->target="_blank"<!-- {/if} -->>

								{$nav.name}

					</a>

				</li>

		<!-- {/if} -->

				<!-- {if $nav.active eq 1} --><!-- {/if} -->

					<!-- {/foreach} -->

		  </ul>

      </div></strong>

在m_left标签下，可以发现首页标签是单独列出来的，而后面的几个选项是通过foreach动态生成，从给的href可以看出。

之前一直没看懂$navigator_list这个参数是怎么传进来的，因为固定思维，一直以为带有‘$’的标签都是根目录下的php文件通过smarty传递过来，所以找遍了所有php文件和dwt文件，都没发现$navigator_list这个参数，后面又试着关键字搜索nav这个表名，以为能找到对应的sql语句，可是找遍仍然没发现，后面接着在page_header.lbi这个文件下调试这几个参数的值，输出这些值，找找看能不能发现什么，顺便把数据库里面nav表的name参数改动，看看变化，依然没什么进展，不过，倒是解决了之前很多的疑问，感觉里面的代码和界面被我调试的面目全非。最终问题是解决了，我无意中翻看其他文件夹，在includes/目录下，我意识到，像导航栏这种常年不变的组件，必须得剥离到共用的地方，很多地方都得调用，如果写在业务逻辑代码里面，会非常臃肿的，我翻了一下，本能的从init.php，lib_base,lib_main这三个文件里面看了看，最后在lib_main文件内找到$navigator_list参数。

呵呵，我想说一句，fuck，几十个文件翻着看，这基本的调用也不给个注释，这叫我们这些菜鸟怎么活啊ORZ
