[Plugin: Export to Excel] Export Custon Fields

I just added custom fields to mine like this:

In includes/loop.php, I changed the part from lines 38-48 (starting $str.=’ …) to this:

$str.= '
          <tr>
            <td>' . mb_convert_encoding(get_the_title(), 'HTML-ENTITIES', 'UTF-8') . '</td>
            <td>' . mb_convert_encoding($post->post_content, 'HTML-ENTITIES', 'UTF-8') . '</td>
            <td>' . get_permalink() .'</td>
            <td>' . get_the_date('Y-m-d', '', '', FALSE) .'</td>
            <td>' . get_the_author() .'</td>
            <td>' . $all_cats . '</td>
            <td>' . $all_tags . '</td>';

// post meta add
$custom_field_keys = get_post_custom_keys(get_the_ID());
foreach ( $custom_field_keys as $key => $value ) {
	$valuet = trim($value);
	if ( '_' == $valuet{0} )
    continue;
    $str .= '<td>'.mb_convert_encoding(get_post_meta($post->ID,$value,true),'HTML-ENTITIES', 'UTF-8').'</td>';
}	

        $str .='
          	</tr>';

Seems to work. Thanks for the plugin!
