I want to have a column (e.g Send Email) in my custom posts (books) list. In each row there should be a button (Send) and when I click on it I want to send an email.
I have seen is a hook manage_posts_custom_column to add custom column but this hook only adds post meta as columns like featured image etc.
How to do this, please help me.

books Post TableHere we can use the filters
manage_{$post->post_type}_posts_custom_column manage_{$post->post_type}_posts_columns or for the books post type:
manage_books_posts_custom_column manage_books_posts_columns Here's an example how we could display a button, for each row in the send_email column:
/** * Books Post Table: Display a utton in each row in the 'send_email' column */ add_action( 'manage_books_posts_custom_column', function ( $column_name, $post_id ) { if ( $column_name == 'send_email') printf( '<input type="button" value="%s" />', esc_attr( __( 'Send Email' ) ) ); }, 10, 2 ); To add the send_email column we can use:
/** * Books Post Table: Add the 'send_email' column */ add_filter('manage_books_posts_columns', function ( $columns ) { if( is_array( $columns ) && ! isset( $columns['send_email'] ) ) $columns['send_email'] = __( 'Send Email' ); return $columns; } ); We could also limit the column width with:
/** * Limit the 'send_email' column width */ add_action( 'admin_print_styles-edit.php', function() { echo '<style> .column-send_email { width: 100px; }</style>'; } ); Here's an example output:
You will then have to implement how the button will work.
ps: I removed the second part from my answer, since that part of your question, would be better served as a new separate question.
