Question

你好堆栈溢出的用户，我有一点问题，

我想在我的网站的上端获取头像，如果用户已登录我想要显示

头像和名称以及个人资料链接，

如果用户未登录我想显示登录和注册按钮

我只知道一点点php，我将不得不使用if else语句但是如何调用wordpress登录用户函数，

感谢

（如果您向我提供了一些有用的示例代码）

我试过这样的事情

 <ul class="nav-userbox nav pull-right">
<?php
if ( is_user_logged_in() ) {
  echo 'Welcome, registered user!';

 <li id="menuLogin" class="dropdown">
        <a class="user-buttons" title="Register" href="./register?to=">

            Register

        </a>
        <a id="navLogin" class="dropdown-toggle user-buttons" data-toggle="dropdown" href="#">

            Login

        </a>
        <div class="dropdown-menu login-form">
            <form id="loginform" method="post" action="./login?to=">
                <input id="user_login" type="text" placeholder="Email or Username" name="log"></input>
                <input id="user_pass" type="password" placeholder="Password" name="pwd"></input>
                <label class="checkbox inline">
                    <input id="rememberme" type="checkbox" value="forever" name="rememberme"></input>

                     Remember                       

                </label>
    <input id="wp-submit" type="submit" value="Log In" name="wp-submit"></input>
    <input type="hidden" value="http://www.entrytestclass.com/main21/wp-admin/" name="redirect_to"></input>
    <input type="hidden" value="" name="instance"></input>
    <input type="hidden" value="login" name="action"></input>

            </form>

            <div class="custom">
                <div id="fb-root" class=" fb_reset" style="display:inline;">
                    <div style="position: absolute; top: -10000px; height: 0px; width: 0px;"></div>

        </div>
    </li>

    }

例如;

 <?php
    if ( is_user_logged_in() ) {
        if (function_exists('get_avatar')) { 
          echo get_avatar( get_the_author_meta('user_email'), 68 );
          the_author_meta('display_name');
        } 
   } else {
       echo '<a href="'.wp_login_url( get_permalink() ).'" title="Login">Login</a>
   }
  ?>

您的代码必须是这样的，

<ul class="nav-userbox nav pull-right">
<?php
if ( is_user_logged_in() ) {
  echo 'Welcome, registered user!';

}

else { ?>

<li id="menuLogin" class="dropdown">
        <a class="user-buttons" title="Register" href="./register?to=">

            Register

        </a>
        <a id="navLogin" class="dropdown-toggle user-buttons" data-toggle="dropdown" href="#">

            Login

        </a>
        <div class="dropdown-menu login-form">
            <form id="loginform" method="post" action="./login?to=">
                <input id="user_login" type="text" placeholder="Email or Username" name="log"></input>
                <input id="user_pass" type="password" placeholder="Password" name="pwd"></input>
                <label class="checkbox inline">
                    <input id="rememberme" type="checkbox" value="forever" name="rememberme"></input>

                     Remember                       

                </label>
                <input id="wp-submit" type="submit" value="Log In" name="wp-submit"></input>
                <input type="hidden" value="http://www.entrytestclass.com/main21/wp-admin/" name="redirect_to"></input>
                <input type="hidden" value="" name="instance"></input>
                <input type="hidden" value="login" name="action"></input>

            </form>

            <div class="custom">
                <div id="fb-root" class=" fb_reset" style="display:inline;">
                    <div style="position: absolute; top: -10000px; height: 0px; width: 0px;"></div>
                    <div style="position: absolute; top: -10000px; height: 0px; width: 0px;"></div>
                </div>
                <script>


                            window.fbAsyncInit = function() {
                           …

                </script>
                <div class="fb-login-button fb_iframe_widget" scope="email,user_about_me,user_location,user_website" size="medium" style="display:inline; vertical-align:middle;" login_text=" " fb-xfbml-state="rendered" fb-iframe-plugin-query="app_id=332446126861609&locale=en_US&login_text=%0A%20%20%20%…about_me%2Cuser_location%2Cuser_website&sdk=joey&size=medium">
                    <span style="vertical-align: bottom; width: 0px; height: 0px;">
                        <iframe class="" height="1000px" frameborder="0" width="1000px" scrolling="no" name="f27f166a4e97fde" allowtransparency="true" title="fb:login_button Facebook Social Plugin" style="border: medium none; visibility: visible; width: 0px; height: 0px;" src="http://www.facebook.com/plugins/login_button.php?app_id=3324…about_me%2Cuser_location%2Cuser_website&sdk=joey&size=medium"></iframe>
                    </span>
                </div>
            </div>
        </div>
    </li>

<?php } ?>

</ul>
