とりあえず、ここまで来た。
<?php
class DateFormHelper extends AppHelper {
function input($title = null, $model = null, $field = null, $value = null) {
$class = "dateForm";
$name = "data[".$model."][".$field."]";
$txt = "\r";
$txt .= "<div class=\"input text\">";
$txt .= "<label for=\"".$model.Inflector::camelize($field)."\">".$title."</label>";
$txt .= "<input class=\"".$class."\" name=\"".$name."[year]\" type=\"text\" maxlength=\"10\" value=\"1970\" />";
$txt .= "年";
$txt .= "<input class=\"".$class."\" name=\"".$name."[month]\" type=\"text\" maxlength=\"10\" value=\"1\" />";
$txt .= "月";
$txt .= "<input class=\"".$class."\" name=\"".$name."[day]\" type=\"text\" maxlength=\"10\" value=\"1\" />";
$txt .= "日";
$txt .= "</div>\r";

return $this->output($txt);
}
}
?>
だが、引数が多すぎる・・・
Helperの中で、引数をどこからか取得できない？
