A modifier in case someone needs it.

This is a modifier based in the truncate modifier, it can be used to "adjust" the size of strings to some length, truncating If necessary or padding if necessary. Usage: |adjust:length:padding:append_if_truncate:break_words Example {$foo|20:"-":"."} Will adjust $foo to 30 characters adding "-" to pad the string if needed. If the string Is truncated "." is added at the end. The default pad filler is "&nbsp;" <?php /* * Smarty plugin * ------------------------------------------------------------- * Type: modifier * Name: adjust * Purpose: Adjust a string to a certain length if necessary, * optionally splitting in the middle of a word, and * appending the $etc string or padding the string * using $pad as filler. * ------------------------------------------------------------- */ function smarty_modifier_adjust($string, $length = 80, $pad = '&nbsp;', $etc = '...', $break_words = false) { if ($length == 0) return ''; if (strlen($string) > $length) { $length -= strlen($etc); $fragment = substr($string, 0, $length+1); if ($break_words) $fragment = substr($fragment, 0, -1); else $fragment = preg_replace('/\s+(\S+)?$/', '', $fragment); return $fragment.$etc; } elseif(strlen($string)<$length) { return $string.str_repeat($pad,$length-strlen($string)); } else { return $string; } } ?>
