Wordpress 将添加元数据框数据保存到多个post类型
我有以下代码在我的Wordpress站点中创建和保存自定义元框。此解决方案适用于我的“工作”帖子类型,但不会保存在标准的“帖子”上。元框在两种post_类型上都显示良好,但仅在“工作”上保存。因此,我认为问题在于save函数,但我无法解释为什么它只适用于一种post_类型 我已经将下面的代码缩减到我认为是最基本的代码 谢谢Wordpress 将添加元数据框数据保存到多个post类型,wordpress,Wordpress,我有以下代码在我的Wordpress站点中创建和保存自定义元框。此解决方案适用于我的“工作”帖子类型,但不会保存在标准的“帖子”上。元框在两种post_类型上都显示良好,但仅在“工作”上保存。因此,我认为问题在于save函数,但我无法解释为什么它只适用于一种post_类型 我已经将下面的代码缩减到我认为是最基本的代码 谢谢 // Allow registering of custom meta boxes add_action( 'add_meta_boxes', 'add_custom_met

经过几天的试验,我对我所经历的问题有了一个半解决方案。在最初的代码中,我试图注册三个元框,但将其中两个放在多个post类型$post_type中,另一个放在一个post类型中。我还没有确定原因,但这就是导致元数据不能保存在某个post类型中的原因 虽然这不是一个完整的答案和详细的细分,但它至少找到了问题的根源,而且我最初认为问题存在于save函数中是正确的,我只是不知道如何解决这个问题。这个解决方案对我来说很好,所以我不会再在这个问题上投入更多的时间 希望这对其他人有用,至少作为一个起点
