这将为您解决问题

$checked_count = count($_POST['check_list']);
$productlist = ''; //initialize an empty string for product list
if ($checked_count > 1) //check if multiple check-boxes are checked
{ 
    $productlist = implode(', ', $_POST['check_list']); //implode all checkbox values in list string
    if(in_array('Others', $_POST['check_list'])) { //check if others is checked
        $productlist .= ', '.$_POST['otherproduct']; //con-cat text in text box lined with others in list string 
        $productlist = str_replace('Others,', '', $productlist); //remove others from the list string (skip if you want others to be in your result'
    }
} elseif ($checked_count == 1) {
    $productlist = ($_POST['check_list'][0] == 'Others') ? $_POST['otherproduct'] : $_POST['check_list'][0]; //if only one checkbox is checked then check its value and use the value
}
echo "<br/>".$productlist;

此外，您可以将客户端和服务器端验证确保从表单中获得正确的输入值。

此外，您可以使用java脚本使您的表单更具互动性。
