ECSHOP中实现ajax弹窗登录

ecshop如何实现ajax 登录 下面请看教程，如果需要收费网站修改得可以联系右侧客户

ECSHOP中的user.php中有处理用户登录的请求。
 

/* 处理 ajax 的登录请求 */
elseif ($action == 'signin')
{
    include_once('includes/cls_json.php');
    $json = new JSON;
 
    $username = !empty($_POST['username']) ? json_str_iconv(trim($_POST['username'])) : '';
    $password = !empty($_POST['password']) ? trim($_POST['password']) : '';
    $captcha = !empty($_POST['captcha']) ? json_str_iconv(trim($_POST['captcha'])) : '';
    $result   = array('error' => 0, 'content' => '');
 
    $captcha = intval($_CFG['captcha']);
    if (($captcha & CAPTCHA_LOGIN) && (!($captcha & CAPTCHA_LOGIN_FAIL) || (($captcha & CAPTCHA_LOGIN_FAIL) && $_SESSION['login_fail'] > 2)) && gd_version() > 0)
    {
        if (empty($captcha))
        {
            $result['error']   = 1;
            $result['content'] = $_LANG['invalid_captcha'];
            die($json->encode($result));
        }
 
        /* 检查验证码 */
        include_once('includes/cls_captcha.php');
 
        $validator = new captcha();
        $validator->session_word = 'captcha_login';
        if (!$validator->check_word($_POST['captcha']))
        {
 
            $result['error']   = 1;
            $result['content'] = $_LANG['invalid_captcha'];
            die($json->encode($result));
        }
    }
 
    if ($user->login($username, $password))
    {
        update_user_info();  //更新用户信息
        recalculate_price(); // 重新计算购物车中的商品价格
        $smarty->assign('user_info', get_user_info());
        $ucdata = empty($user->ucdata)? "" : $user->ucdata;
        $result['ucdata'] = $ucdata;
        $result['content'] = $smarty->fetch('library/member_info.lbi');
    }
    else
    {
        $_SESSION['login_fail']++;
        if ($_SESSION['login_fail'] > 2)
        {
            $smarty->assign('enabled_captcha', 1);
            $result['html'] = $smarty->fetch('library/member_info.lbi');
        }
        $result['error']   = 1;
        $result['content'] = $_LANG['login_failure'];
    }
    die($json->encode($result));
}

/* 处理 ajax弹窗登录请求 */
elseif ($action == 'ajax_login')
{
    include_once('includes/cls_json.php');
    $json = new JSON;
 
    $username = !empty($_POST['username']) ? json_str_iconv(trim($_POST['username'])) : '';
    $password = !empty($_POST['password']) ? trim($_POST['password']) : '';
    $result   = array('error' => 0, 'content' => '');
 
    $captcha = intval($_CFG['captcha']);
    if ($user->login($username, $password))
    {
        update_user_info();  //更新用户信息
        recalculate_price(); // 重新计算购物车中的商品价格
        $smarty->assign('user_info', get_user_info());
        $ucdata = empty($user->ucdata)? "" : $user->ucdata;
        $result['ucdata'] = $ucdata;
        $result['content'] = $smarty->fetch('library/member_info.lbi');
    }
    else
    {
        $result['error']   = 1;
        $result['content'] = $_LANG['login_failure'];
    }
    die($json->encode($result));
}

把下面代码

// 不需要登录的操作或自己验证是否登录（如ajax处理）的act
$not_login_arr =
array('login','act_login','register','act_register','act_edit_password','get_password','send_pwd_email','password', 'signin', 'add_tag', 'collect', 'return_to_cart', 'logout', 'email_list', 'validate_email', 'send_hash_mail', 'order_query', 'is_registered', 'check_email','clear_history','qpassword_name', 'get_passwd_question', 'check_answer');

改成

// 不需要登录的操作或自己验证是否登录（如ajax处理）的act
$not_login_arr =
array('ajax_login','login','act_login','register','act_register','act_edit_password','get_password','send_pwd_email','password', 'signin', 'add_tag', 'collect', 'return_to_cart', 'logout', 'email_list', 'validate_email', 'send_hash_mail', 'order_query', 'is_registered', 'check_email','clear_history','qpassword_name', 'get_passwd_question', 'check_answer');

common.js文件下， 在openLginDiv()方法里，将newDiv.innerHTML的HTML代码修改下，在登录框标签里加个ajaxLoginSubmit()方法。

//生成层内内容
  newDiv.innerHTML = '<form id="ajax_loginForm">用户名：<br><input type="text" name="username" id="ajax_username"/>密码：<br><input type="password" name="password" id="ajax_password"/><br><br><button type="button" οnclick="ajaxLoginSubmit()">登录</button> <button type="button" οnclick="closeLoginForm()">关闭</button></form>';

再自己写两个方法即可

function ajaxLoginSubmit(){
    var username = document.getElementById('ajax_username').value;
	var password = document.getElementById('ajax_password').value;
	Ajax.call('user.php?act=ajax_login','username='+username+'&password='+password,ajaxLoginResponse,'POST','JSON');
}
 
function ajaxLoginResponse(result){
    if(result.error == 0){
	    alert('登录成功');
	}else{
	    alert('登录失败');
	}
	return false;
}

到这里就完成了ecshop ajax 登录了
