Add ID and Parent Comment ID Columns to the Comments Table in /wp-admin
My task was to add two columns to the wp-admin/edit-comments.php
page – with comment ID itself and its parent comment ID. Something like this:
add_filter( 'manage_edit-comments_columns', 'rudr_add_comments_columns' );
function rudr_add_comments_columns( $my_cols ){
// $my_cols is the array of all column IDs and labels
// if you know arrays, you can add, remove or change column order with no problems
// like this:
/*
$my_cols = array(
'cb' => '', // do not forget about the CheckBox
'author' => 'Author',
'comment' => 'Comment',
'm_comment_id' => 'ID', // added
'm_parent_id' => 'Parent ID', // added
'response' => 'In reply to',
'date' => 'Date'
);
*/
// but the above way is not so good - there could be problems when plugins would like to hook the comment columns
// so, better like this:
$misha_columns = array(
'm_comment_id' => 'ID',
'm_parent_id' => 'Parent ID'
);
$my_cols = array_slice( $my_cols, 0, 3, true ) + $misha_columns + array_slice( $my_cols, 3, NULL, true );
// if you want to remove a column, you can just use:
// unset( $my_cols['response'] );
// return the result
return $my_cols;
}
add_action( 'manage_comments_custom_column', 'rudr_add_comment_columns_content', 10, 2 );
function rudr_add_comment_columns_content( $column, $comment_ID ) {
global $comment;
switch ( $column ) :
case 'm_comment_id' : {
echo $comment_ID; // or echo $comment->comment_ID;
break;
}
case 'm_parent_id' : {
// try to print_r( $comment ); to see more comment information
echo $comment->comment_parent; // this will be printed inside the column
break;
}
endswitch;
}
Let me suppose that your newly created comment columns are too wide, so this small piece of code should help:
add_action( 'admin_head', 'rudr_columns_too_wide' );
function rudr_columns_too_wide(){
echo '';
}
P.S. Yes, everything should be added to functions.php
.
