我正在尝试在我的WooCommerce网站上设置自定义排序，特别是我希望按所有项目的属性 - 大小排序。我找到了一个教程来帮助解决这个问题 - http://new.galalaly.me//2013/05/woocommerce-sort-by-custom-attributes/ - 而且我认为我已经很好地遵循了它，但似乎代码可能已经过时了？
我可以让网站识别我的自定义排序，但它实际上并不根据大小排序，它只是默认返回产品名称的字母顺序。但是，它只识别自从添加教程中的代码以来添加或更新的项目（将属性保存到元数据，以便我们可以按它排序）。因此，如果这些项目是较旧的项目，那么当我按大小排序时，它们甚至不会显示在结果中。很明显代码在某种程度上起作用，我似乎无法弄清楚为什么它实际上并没有按大小排序。
我已经检查过order_pa_size是否存在于数据库中并且输入的顺序正确，而且确实如此。我确定我只是错过了一些东西，但在尝试了一切之后我才能想到我很难过。任何帮助将不胜感激。这是我的代码 -

答案 0 :(得分：0)
因此，对于它的价值，这就是我最终做的......它不是一个优雅的解决方案，但它的工作原理。并不优雅，我的意思是它的丑陋，可怕，可怕和糟糕......但它有效，我需要它才能工作，所以我会接受它。
