本文介绍了如何修改joomla k2的内容显示顺序，以适应短租公寓网站的需求。通过调整componentscom_k2 emplatesdefaultitem.php和view.html.php文件，实现了将图库展示提前至标题下方，详细记录了修改过程，为后续的k2二次开发提供了参考。
今天对joomla k2的功能及布局做了一个小小的研究与更改，在这边记录一下，以备后用。
原来的k2内容展示页的显示顺序大概是这个样子的：1、标题；2、按钮之类；3、介绍；4、全文；5、额外字段；（不做一一列举）........最后才是图库展示。但似乎不符合我们接受的一般规律，我这次建的是一家短租公寓网站：3c-home.com.希望能直观的先显示图库，再显示额外字段，然后显示其他的，然后我找k2的源代码做个修改。
一、item.php文件的修改
既然是文章显示，应该就是修改\components\com_k2\templates\default\item.php这个文件喽，来看一下部分源代码：
<!-- Start K2 Item Layout -->
<span id="startOfPageId<?php echo JRequest::getInt('id'); ?>"></span>

Note regarding 'Related Items'!
If you add:
- the CSS rule 'overflow-x:scroll;' in the element div.itemRelated {…} in the k2.css
- the class 'k2Scroller' to the ul element below
- the classes 'k2ScrollerElement' and 'k2EqualHeights' to the li element inside the foreach loop below
- the style attribute 'style="width:<?php echo $item->imageWidth; ?>px;"' to the li element inside the foreach loop below
...then your Related Items will be transformed into a vertical-scrolling block, inside which, all items have the same height (equal column heights). This can be very useful if you want to show your related articles or products with title/author/category/image etc., which would take a significant amount of space in the classic list-style display.
