if ( isset( $vars['orderby'] ) && 'mailer_order' == $vars['orderby'] ) {
$vars = array_merge( $vars, array(
'meta_key' => 'mailer_order',
'orderby' => 'meta_value_num'
) );
}

return $vars;
}
add_filter( 'request', 'mailer_order_column_orderby' );

function mailer_order_column_register( $columns ) {
$columns['mailer_order'] = __( 'Mailer Order', 'my-plugin' );

return $columns;
}
add_filter( 'manage_edit-post_columns', 'mailer_order_column_register' );

function mailer_order_column_display( $column_name, $post_id ) {
if ( 'mailer_order' != $column_name )
return;

$price = get_post_meta($post_id, 'mailer_order', true);
if ( !$price )
$price = '<em>' . __( '', 'my-plugin' ) . '</em>';

echo $price;
}
add_action( 'manage_posts_custom_column', 'mailer_order_column_display', 10, 2 );

Hello Arnav,

This function seems to work perfectly thank you!

I can't post anymore funds at this time but I will drop you a line in a few day and do a direct paypal transfer. But you are totally right, I did under priced this. Now wpquestions is back online, you will see alot more of me.

I would have never figured this out, Thank you!
