功能前台化已成为WordPress主题制作的一大趋势,抛却缓慢臃肿的后台不说,前台便捷操作能给用户带来良好体验。登录与注册是网站的重要功能之一,这篇文章将讲述如何实现漂亮的WordPress前台登录注册功能,此外观移植自觉唯主题。

简要说明

此功能的实现是由AJAX提交表格数据代替PHP submit提交至WordPress自带的admin-ajax.php,再进行wordpress内部的php验证处理,基于功能简化要求,使用了jquery表单验证库,在输入界面就提醒用户的明显错误,如邮箱格式不正确等等。

必须文件

  • jQuery 核心库
  • jQuery Validation Plugin 表单验证
  • 以上文件必须引入,请下载jQuery Validation Plugin 表单验证修改版,下载地址见文章末尾

界面实现

首先使用php和css组织基本界面。

php代码如下:

点击登录或注册弹窗锚点

PHP

<div id="login-reg"> <span data-sign="0" id="user-login" class="user-login"><?php _e(' 登录','tinection'); ?></span> <span data-sign="1" id="user-reg" class="user-reg"><?php _e('注册','tinection'); ?></span> </div>

弹窗代码

PHP

<div id="sign" class="sign"><div class="part loginPart"> <form id="login" action="<?php echo get_option('home'); ?>/wp-login.php" method="post" novalidate="novalidate"><div id="register-active" class="switch"><i class="fa fa-toggle-on"></i>切换注册</div><h3>登录<p class="status"></p></h3><label class="icon" for="username"><i class="fa fa-user"></i></label> <input class="input-control" id="username" type="text" placeholder="请输入用户名" name="username" required="" aria-required="true"><label class="icon" for="password"><i class="fa fa-lock"></i></label> <input class="input-control" id="password" type="password" placeholder="请输入密码" name="password" required="" aria-required="true"><p class="safe"> <label class="remembermetext" for="rememberme"><input name="rememberme" type="checkbox" checked="checked" id="rememberme" class="rememberme" value="forever">记住我的登录</label> <a class="lost" href="<?php echo get_option('home'); ?>/wp-login.php?action=lostpassword"><?php _e('忘记密码 ?','tinection'); ?></a><input class="submit" type="submit" value="登录" name="submit"><a class="close"><i class="fa fa-times"></i></a> <input type="hidden" id="security" name="security" value="<?php echo wp_create_nonce( 'security_nonce' );?>"><input type="hidden" name="_wp_http_referer" value="<?php echo $_SERVER['REQUEST_URI']; ?>"></form></div><div class="part registerPart"> <form id="register" action="<?php bloginfo('url'); ?>/wp-login.php?action=register" method="post" novalidate="novalidate"><div id="login-active" class="switch"><i class="fa fa-toggle-off"></i>切换登录</div><h3>注册<p class="status"></p></h3><label class="icon" for="user_name"><i class="fa fa-user"></i></label> <input class="input-control" id="user_name" type="text" name="user_name" placeholder="输入英文用户名" required="" aria-required="true"><label class="icon" for="user_email"><i class="fa fa-envelope"></i></label> <input class="input-control" id="user_email" type="text" name="user_email" placeholder="输入常用邮箱" required="" aria-required="true"><label class="icon" for="user_pass"><i class="fa fa-lock"></i></label> <input class="input-control" id="user_pass" type="password" name="user_pass" placeholder="密码最小长度为6" required="" aria-required="true"><label class="icon" for="user_pass2"><i class="fa fa-retweet"></i></label> <input class="input-control" type="password" id="user_pass2" name="user_pass2" placeholder="再次输入密码" required="" aria-required="true"><input class="submit" type="submit" value="注册" name="submit"><a class="close"><i class="fa fa-times"></i></a> <input type="hidden" id="user_security" name="user_security" value="<?php echo wp_create_nonce( 'user_security_nonce' );?>"><input type="hidden" name="_wp_http_referer" value="<?php echo $_SERVER['REQUEST_URI']; ?>"> </form></div></div>

此php代码请放到要显示登录按钮的地方,比如导航条。

CSS样式代码如下:

css样式可直接放到style.css文件中,
功能实现

ajax提交

ajax提交表单数据代码已经包含在修改版jQuery Validation Plugin 表单验证js文件中,主要是将ajax的提交action指向admin-ajax.php这个wordpress自带ajax处理接口,请直接下载即可。

表单后台处理

先在functions.php文件中添加如下几个函数,代码如下:

PHP

/* 获取当前页面url/* ---------------- */function tin_get_current_page_url(){$ssl = (!empty($_SERVER['HTTPS']) &amp;&amp; $_SERVER['HTTPS'] == 'on') ? true:false;$sp = strtolower($_SERVER['SERVER_PROTOCOL']);$protocol = substr($sp, 0, strpos($sp, '/')) . (($ssl) ? 's' : '');$port = $_SERVER['SERVER_PORT'];$port = ((!$ssl &amp;&amp; $port=='80') || ($ssl &amp;&amp; $port=='443')) ? '' : ':'.$port;$host = isset($_SERVER['HTTP_X_FORWARDED_HOST']) ? $_SERVER['HTTP_X_FORWARDED_HOST'] : isset($_SERVER['HTTP_HOST']) ? $_SERVER['HTTP_HOST'] : $_SERVER['SERVER_NAME'];return $protocol . '://' . $host . $port . $_SERVER['REQUEST_URI'];}/* AJAX登录变量/* -------------- */function ajax_sign_object(){$object = array();$object[redirecturl] = tin_get_current_page_url();$object[ajaxurl] = admin_url( '/admin-ajax.php' );$object[loadingmessage] = '正在请求中,请稍等...';$object_json = json_encode($object);return $object_json;}/* AJAX登录验证/* ------------- */function tin_ajax_login(){$result = array();if(isset($_POST['security']) &amp;&amp; wp_verify_nonce( $_POST['security'], 'security_nonce' ) ){$creds = array();$creds['user_login'] = $_POST['username'];$creds['user_password'] = $_POST['password'];$creds['remember'] = ( isset( $_POST['remember'] ) ) ? $_POST['remember'] : false;$login = wp_signon($creds, false);if ( ! is_wp_error( $login ) ){$result['loggedin'] = 1;}else{$result['message'] = ( $login-&gt;errors ) ? strip_tags( $login-&gt;get_error_message() ) : '<strong>ERROR</strong>: ' . esc_html__( '请输入正确用户名和密码以登录', 'tinection' );}}else{$result['message'] = __('安全认证失败,请重试!','tinection');}header( 'content-type: application/json; charset=utf-8' );echo json_encode( $result );exit;}add_action( 'wp_ajax_ajaxlogin', 'tin_ajax_login' );add_action( 'wp_ajax_nopriv_ajaxlogin', 'tin_ajax_login' );/* AJAX注册验证/* ------------- */function tin_ajax_register(){$result = array();if(isset($_POST['security']) &amp;&amp; wp_verify_nonce( $_POST['security'], 'user_security_nonce' ) ){$user_login = sanitize_user($_POST['username']);$user_pass = $_POST['password'];$user_email = apply_filters( 'user_registration_email', $_POST['email'] );$errors = new WP_Error();if( ! validate_username( $user_login ) ){$errors-&gt;add( 'invalid_username', __( '请输入一个有效用户名','tinection' ) );}elseif(username_exists( $user_login )){$errors-&gt;add( 'username_exists', __( '此用户名已被注册','tinection' ) );}elseif(email_exists( $user_email )){$errors-&gt;add( 'email_exists', __( '此邮箱已被注册','tinection' ) );}do_action( 'register_post', $user_login, $user_email, $errors );$errors = apply_filters( 'registration_errors', $errors, $user_login, $user_email );if ( $errors-&gt;get_error_code() ){$result['success'] = 0;$result['message'] = $errors-&gt;get_error_message();} else {$user_id = wp_create_user( $user_login, $user_pass, $user_email );if ( ! $user_id ) {$errors-&gt;add( 'registerfail', sprintf( __( '无法注册,请联系管理员','tinection' ), get_option( 'admin_email' ) ) );$result['success'] = 0;$result['message'] = $errors-&gt;get_error_message();} else{update_user_option( $user_id, 'default_password_nag', true, true ); //Set up the Password change nag.wp_new_user_notification( $user_id, $user_pass );$result['success'] = 1;$result['message'] = esc_html__( '注册成功','tinection' );//自动登录wp_set_current_user($user_id);wp_set_auth_cookie($user_id);$result['loggedin'] = 1;}}}else{$result['message'] = __('安全认证失败,请重试!','tinection');}header( 'content-type: application/json; charset=utf-8' );echo json_encode( $result );exit;}add_action( 'wp_ajax_ajaxregister', 'tin_ajax_register' );add_action( 'wp_ajax_nopriv_ajaxregister', 'tin_ajax_register' );

PHPjs必须的变量引入

请在主题的header.php或footer.php中引入如下代码:

<script type="text/javascript">/* <![CDATA[ */var ajax_sign_object = <?php echo ajax_sign_object(); ?>;/* ]]> */</script>

此代码作用是声明部分js必须的变量,而这些变量是由前面的php函数动态产生的。
