How to add / remove columns in Woocommerce admin product list

Question

I want to customize the columns in Woocommerce admin area when viewing the product list.

Specifically, I want to remove some columns, and add several custom field columns.

I tried many solutions listed online, and I can remove columns and add new ones like this:

add_filter( 'manage_edit-product_columns', 'show_product_order',15 );
function show_product_order($columns){

   //remove column
   unset( $columns['tags'] );

   //add column
   $columns['offercode'] = __( 'Offer Code'); 

   return $columns;
}

But how do I populate the new column with the actual product data (in this case, a custom field called 'offercode')?

Answer 1

The filter manage_edit-{post_type}_columns is only used to actually add the column. To control what is displayed in the column for each post (product), you can use the manage_{post_type}_posts_custom_column action. This action is called for each custom column for every post, and it passes two arguments: $column and $postid.

Using this action is quite easy, you can find an example to display the custom field "offercode" below:

add_action( 'manage_product_posts_custom_column', 'wpso23858236_product_column_offercode', 10, 2 );  function wpso23858236_product_column_offercode( $column, $postid ) {     if ( $column == 'offercode' ) {         echo get_post_meta( $postid, 'offercode', true );     } } 

You could also use a plugin to control this behaviour, such as Admin Columns.

Answer 2

this table view is used by many plugins and wordpress itself. You have to check the column name. $columns['tags'] is the tag in Wordpress Post View, not in Woocommerce!

Here is a list of some $columns used by Woocommerce:

$columns['cb']   $columns['thumb'] $columns['name']  $columns['sku']  $columns['is_in_stock'] $columns['price'] $columns['product_cat']  $columns['product_tag'] $columns['featured'] $columns['product_type'] $columns['date'] 

and that is the correct filter to apply these removals.

add_filter( 'manage_edit-product_columns', 'change_columns_filter',10, 1 ); function change_columns_filter( $columns ) { unset($columns['product_tag']); unset($columns['sku']); unset($columns['featured']); unset($columns['product_type']); return $columns; }

In case someone wants to insert in a certain order, here is how to add the column to be right after Price:

add_filter( 'manage_edit-product_columns', 'wootix_show_product_order', 15 ) ;

function wootix_show_product_order( $columns )
{
    //add column
    $arr = array( 'wootix_credit' => __( 'Credits', 'wootix' ) ) ;

    array_splice( $columns, 6, 0, $arr ) ;

    return $columns ;
}
