一、扩展你的Smarty
1、准备功夫
PHP代码:--------------------------------------------------------------------------------
function Smarty_function_page ( $params, &$Smarty )
{
$href = '#';
$space = ' ';
$frist = NULL;
$last = NULL;
$page = 5;
extract($params);
if ( !$row || $row <= 1 ) return ' ';
$pages = $row;
$curr_page = $now ? $now : 1;
$offset = 2;
$from = $curr_page - $offset;
$to = $curr_page + $page - $offset - 1;
if ( $page > $pages )
{
$from = 1;
$to = $pages;
}
else
{
if ( $from < 1)
{
$to = $curr_page + 1 - $from;
$from = 1;
if ( ( $to - $from ) < $page && ( $to - $from ) < $pages )
{
$to = $page;
}
}
elseif ( $to > $pages )
{
$from = $curr_page - $pages + $to;
$to = $pages;
if ( ( $to - $from ) < $page && ( $to - $from) < $pages )
{
$from = $pages - $page + 1;
}
}
}
if ( $frist && ( $curr_page - 1 ) >= 1 ) $p['frist'] = '<a href="' . $href . '1">' . $frist . '</a>';
if ( $prev && ( $i = $curr_page - 1 ) >= 1 ) $p['prev'] = '<a href="' . $href . $i . '">' . $prev . '</a>';
for( $i = $from; $i <= $to; $i ++ )
{
if ( $i == $curr_page )
{
$p[$i] = '<a href="' . $href . $i . '" class="nowpage" target="_self">[' . $i . ']</a>';
}
else
{
$p[$i] = '<a href="' . $href . $i . '" target="_self">' . $i . '</a>';
}
}
if ( $next && ( $i = $curr_page + 1 ) <= $pages ) $p['next'] = '<a href="' . $href . $i . '" target="_self">' . $next . '</a>';
if ( $last && ( $curr_page + 1 ) <= $pages ) $p['last'] = '<a href="' . $href . $pages . '" target="_self">' . $last . '</a>';
return implode( $space, $p );
} // end func
