在上篇文章給大家介紹了使用openSpeDiv方法實(shí)現(xiàn)Ecshop登錄彈窗框效果，大家點(diǎn)擊參考下
下面介紹如何實(shí)現(xiàn)AJAX彈窗登錄。
在ECSHOP中的user.PHP中有處理用戶登錄的請(qǐng)求。
/* 處理 ajax 的登錄請(qǐng)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));
}
/* 檢查驗(yàn)證碼 */
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(); //更新用戶信息
recalculate_price(); // 重新計(jì)算購物車中的商品價(jià)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($result));
}
把上面這段代碼修改一下，刪掉需要驗(yàn)證碼的部分
改成
/* 處理 ajax彈窗登錄請(qǐng)求 */
elseif ($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(); //更新用戶信息
recalculate_price(); // 重新計(jì)算購物車中的商品價(jià)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));
}
將
// 不需要登錄的操作或自己驗(yàn)證是否登錄（如ajax處理）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
// 不需要登錄的操作或自己驗(yàn)證是否登錄（如ajax處理）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，將newDiv.innerHTML的HTML代碼修改下，在登錄框標(biāo)簽里加個(gè)ajaxLoginSubmit()方法。
//生成層內(nèi)內(nèi)容
newDiv.innerHTML = 'form id="ajax_loginForm">用戶名：br>input type="text" name="username" id="ajax_username"/>密碼：br>input type="password" name="password" id="ajax_password"/>br>br>button type="button" onclick="ajaxLoginSubmit()">登錄/button> button type="button" onclick="closeLoginForm()">關(guān)閉/button>/form>';
再自己寫兩個(gè)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('登錄成功');
}else{
alert('登錄失敗');
}
return false;
}
