在WordPress中给推荐文章添加缩略图
栏目：WordPress时间：2013-10-27 20:03:05
对于如何在WordPress中显示推荐文章，网上有非常多方法，但似乎不是那么令人满意。在本教程中，我们将与大家分享一种可以让用户选择某些特定文章并通过使用WordPress2.9新增的缩略图功能来显示这些文章的方法。此方法可以避免使用“置顶文章”，在其他一些自定义的方法中由于其他功能不可避免要使用到“置顶文章”。
注意: 使用本教程需要熟悉一些WordPress、PHP、HTML和CSS知识。
我们修改了由W3C Gallery公司San制作的Featured Posts Lists插件。虽然San给这款插件创建了一个高级版本可以显示图片，但它需要一个自定义字段。这样一来，你只能在2.9中使用这个缩略图功能。
最终效果
