Вывод доп. поля с limit, DLE 9.6

вопрос

В DLE 9.7 появился тег [xfvalue_X limit="X2"], но как вывести информацию в краткой новости из доп. поля с ограниченным количеством символов на DLE 9.6 ?

В show.short.php найти две закомментированные строки:

// Обработка дополнительных полей

и между ними заменить код:

        if( $xfound ) {
            $xfieldsdata = xfieldsdataload( $row['xfields'] );
            
            foreach ( $xfields as $value ) {
                $preg_safe_name = preg_quote( $value[0], "'" );

                if ( $value[6] AND !empty( $xfieldsdata[$value[0]] ) ) {
                    $temp_array = explode( ",", $xfieldsdata[$value[0]] );
                    $value3 = array();

                    foreach ($temp_array as $value2) {

                        $value2 = trim($value2);
                        $value2 = str_replace("&#039;", "'", $value2);

                        if( $config['allow_alt_url'] == "yes" ) $value3[] = "" . $value2 . "";
                        else $value3[] = "" . $value2 . "";
                    }

                    $xfieldsdata[$value[0]] = implode(", ", $value3);

                    unset($temp_array);
                    unset($value2);
                    unset($value3);

                }
        
                if( empty( $xfieldsdata[$value[0]] ) ) {
                    $tpl->copy_template = preg_replace( "'\\[xfgiven_{$preg_safe_name}\\](.*?)\\[/xfgiven_{$preg_safe_name}\\]'is", "", $tpl->copy_template );
                    $tpl->copy_template = str_replace( "[xfnotgiven_{$value[0]}]", "", $tpl->copy_template );
                    $tpl->copy_template = str_replace( "[/xfnotgiven_{$value[0]}]", "", $tpl->copy_template );
                } else {
                    $tpl->copy_template = preg_replace( "'\\[xfnotgiven_{$preg_safe_name}\\](.*?)\\[/xfnotgiven_{$preg_safe_name}\\]'is", "", $tpl->copy_template );
                    $tpl->copy_template = str_replace( "[xfgiven_{$value[0]}]", "", $tpl->copy_template );
                    $tpl->copy_template = str_replace( "[/xfgiven_{$value[0]}]", "", $tpl->copy_template );
                }

                    $xfieldsdata[$value[0]] = trim(str_replace( "", " ", str_replace( "", " ", str_replace( "\n", " ", str_replace( "\r", "", $xfieldsdata[$value[0]] ) ) ) ));
        
                    if( $count AND dle_strlen( $xfieldsdata[$value[0]], $config['charset'] ) > $count ) {
