如何在自定义帖子类型的类别网格中添加自定义列？ [英] How to add custom column in category grid of custom post type?

问题描述

我试图使用 manage _ {$ taxonomy} _custom_column 将类别ID添加到自定义帖子类型的类别列表中，我发现该功能现已弃用。

以下页面上的过滤器现在为红色，没有可用的使用信息：

解决方案

试试这个

  //显示列标题
函数custom_column_header（$ columns）{
 $ columns ['header_name'] ='用于显示的标题名称'; 
个返回$列； 
} 
 
 add_filter（ manage_edit-（your-texanomy）_columns，'custom_column_header'，10）; 
 
 //要显示列值
函数custom_column_content（$ value，$ column_name，$ tax_id）{
返回$ tax_id; 
} 
 add_action（ manage_（your-texanomy）_custom_column，‘custom_column_content’，10，3）; 
  

I'm trying to add the category ID to the category list table for a custom post type using manage_{$taxonomy}_custom_column, and I found out that the function is now deprecated.

The filter is now red on the following page with no usage information available: https://codex.wordpress.org/Plugin_API/Action_Reference/manage_posts_custom_column

And the following page says the filter is now deprecated, with no followup information since version 3: http://adambrown.info/p/wp_hooks/hook/manage_{$taxonomy}_custom_column

I came across this solution on github, but it doesn't work: https://gist.github.com/maxfenton/593473788c2259209694

I've not found any solution that serves as a replacement for manage_{$taxonomy}_custom_column. Does anyone have any idea how to go about adding a category ID column in the category grid view?

Here is a screenshot showing where I want to add the ID:

解决方案

Try this

// To show the column header
function custom_column_header( $columns ){
  $columns['header_name'] = 'Header Name for Display'; 
  return $columns;
}

add_filter( "manage_edit-(your-texanomy)_columns", 'custom_column_header', 10);

// To show the column value
function custom_column_content( $value, $column_name, $tax_id ){
   return $tax_id ;
}
add_action( "manage_(your-texanomy)_custom_column", 'custom_column_content', 10, 3);
