复制代码 代码如下:

{
if(empty($mval)) $mval = date("m");
if(empty($dval)) $dval = date("d");
if(empty($yval)) $yval = date("Y");
$months = array(1 => "January", 2 => "February", 3 => "March", 4 => "April", 5 => "May", 6 => "June", 7 => "July", 8 => "August", 9 => "September", 10 => "October", 11 => "November", 12 => "December");
$out = "<select name='$mid' id='$mid'>";
foreach($months as $val => $text)
if($val == $mval) $out .= "<option value='$val' selected>$text</option>";
else $out .= "<option value='$val'>$text</option>";
$out .= "</select> ";
$out .= "<select name='$did' id='$did'>";
for($i = 1; $i <= 31; $i++)
if($i == $dval) $out .= "<option value='$i' selected>$i</option>";
else $out .= "<option value='$i'>$i</option>";
$out .= "</select> ";
$out .= "<select name='$yid' id='$yid'>";
for($i = date("Y"); $i <= date("Y") + 2; $i++)
if($i == $yval) $out.= "<option value='$i' selected>$i</option>";
else $out.= "<option value='$i'>$i</option>";
$out .= "</select>";
return $out;
}
