如何在ecshop注册的时候，新增生日字段，具体步骤如下：
第一步：修改includes/lib_passport.php
找到：function register($username, $password, $email, $other = array())
替换：function register($username, $password, $email, $other = array(), $birthday)
第二步：修改根目录的 user.php
找到：include_once(ROOT_PATH . ‘includes/lib_passport.php’);
下面增加：$birthday = trim($_POST[‘birthdayYear’]) .’-‘. trim($_POST[‘birthdayMonth’]) .’-‘. trim($_POST[‘birthdayDay’]);
找到：/* 写入密码提示问题和答案 */ if (!empty($passwd_answer) && !empty($sel_question))
上面增加：$sql = ‘UPDATE ‘ . $ecs->table(‘users’) . " SET `birthday`=’$birthday’ WHERE `user_id`=’" . $_SESSION[‘user_id’] . "’"; $db->query($sql);
找到：if (register($username, $password, $email, $other) !== false)
替换：if (register($username, $password, $email, $other,$birthday) !== false)
第三步：修改ecshop模板中注册文件 themes/yourstemplatename/user_passport.dwt，如果是默认模板，则是themes/default /user_passport.dwt
找到这段代码： <tr> <td align="right">{$lang.label_confirm_password}</td> <td> <input name="confirm_password" type="password"id="conform_password" class="inputBg" style="width:179px;"/> <span style="color:#FF0000" id="conform_password_notice"> *</span> </td> </tr>
在其之后，插入代码 <tr> <td width="28%" align="right" bgcolor="#FFFFFF">{$lang.birthday}： </td> <td width="72%" align="left" bgcolor="#FFFFFF"> {html_select_date field_order=YMD prefix=birthday start_year=-60 end_year=+1 display_days=true month_format=%m day_value_format=%02d time=this.birthday} </td> </tr>
，到尽头，也许快乐，或有时孤独，如果心在远方，
