This article mainly introduces to you the implementation of ajax pop-up window login function in ecshop. The code is simple and easy to understand, very good, and has reference value. Friends who need it can refer to it.

I will introduce it to you in the previous article In order to use the openSpep method to achieve the Ecshop login pop-up window box effect, please click for reference

The following describes how to implement AJAX pop-up window login.

User.PHP in ECSHOP handles user login requests.

/* 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)); 
}

Modify the above code and delete the part that requires a verification code

and change it to

/* 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)); 
}

Change

// 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');

to

// 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 file,

In the openLginp() method, modify the HTML code of newp.innerHTML and add an ajaxLoginSubmit() method to the login box label.

//生成层内内容 
 newp.innerHTML = &#39;<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" onclick="ajaxLoginSubmit()">登录</button> <button type="button" onclick="closeLoginForm()">关闭</button></form>&#39;;

Just write two methods yourself

function ajaxLoginSubmit(){ 
 var username = document.getElementById(&#39;ajax_username&#39;).value; 
 var password = document.getElementById(&#39;ajax_password&#39;).value; 
 Ajax.call(&#39;user.php?act=ajax_login&#39;,&#39;username=&#39;+username+&#39;&password=&#39;+password,ajaxLoginResponse,&#39;POST&#39;,&#39;JSON&#39;); 
} 
function ajaxLoginResponse(result){ 
 if(result.error == 0){ 
  alert(&#39;登录成功&#39;); 
 }else{ 
  alert(&#39;登录失败&#39;); 
 } 
 return false; 
}

The above is what I compiled For everyone, I hope it will be helpful to everyone in the future.
