在为客户直至用户中心的时候，需要实现已经登录用户重置密码的功能，我们可以通过短代码在主题的任何位置插入重置密码的表单：

第一步：在functions当中插入如下代码：

if (is_singular()) :
    $current_url = get_permalink($post->ID);
else :
    $pageURL = 'http';
    if ($_SERVER["HTTPS"] == "on") $pageURL .= "s";
    $pageURL .= "://";
    if ($_SERVER["SERVER_PORT"] != "80") $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
    else $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
    $current_url = $pageURL;
endif;      
$redirect = $current_url;

ob_start();

    // show any error messages after form submission
    pippin_show_error_messages(); ?>

    <?php if(isset($_GET['password-reset']) &amp;&amp; $_GET['password-reset'] == 'true') { ?>
        <div class="pippin_message success"&gt;
            <span><?php _e('Password changed successfully','rcp'); ?></span>
        </div>
    <?php } ?>
    <form id="pippin_password_form" method="POST" action="<?php echo $current_url; ?>"&gt;
        <fieldset>
            <p>
                <label for="pippin_user_pass"&gt;<?php _e('New Password','rcp'); ?></label>
                <input name="pippin_user_pass" id="pippin_user_pass" class="<a href="https://www.jb51.cc/tag/required/" target="_blank" class="keywords">required</a>" type="password"/&gt;
            </p>
            <p>
                <label for="pippin_user_pass_confirm"&gt;<?php _e('Password Confirm','rcp'); ?></label>
                <input name="pippin_user_pass_confirm" id="pippin_user_pass_confirm" class="<a href="https://www.jb51.cc/tag/required/" target="_blank" class="keywords">required</a>" type="password"/&gt;
            </p>
            <p>
                <input type="hidden" name="pippin_action" value="reset-password"/&gt;
                <input type="hidden" name="pippin_redirect" value="<?php echo $redirect; ?>"/&gt;
                <input type="hidden" name="pippin_password_nonce" value="<?php echo wp_create_nonce('rcp-password-nonce'); ?>"/&gt;
                <input id="pippin_password_submit" type="submit" value="<?php _e('Change Password','pippin'); ?>"/&gt;
            </p>
        </fieldset>
    </form>
<?php
return ob_get_clean();  

    global $user_ID;

    if(!is_user_logged_in())
        return;

    if(wp_verify_nonce($_POST['pippin_password_nonce'],'rcp-password-nonce')) {

        if($_POST['pippin_user_pass'] == '' || $_POST['pippin_user_pass_confirm'] == '') {
            // password(s) field empty
            pippin_errors()->add('password_empty',__('Please enter a password,and confirm it','pippin'));
        }
        if($_POST['pippin_user_pass'] != $_POST['pippin_user_pass_confirm']) {
            // passwords do not match
            pippin_errors()->add('password_mismatch',__('Passwords do not match','pippin'));
        }

        // retrieve all error messages,if any
        $errors = pippin_errors()->get_error_messages();

        if(empty($errors)) {
            // change the password here
            $user_data = array(
                'ID' => $user_ID,'user_pass' => $_POST['pippin_user_pass']
            );
            wp_update_user($user_data);
            // send password change email here (if WP doesn't)
            wp_redirect(add_query_arg('password-reset','true',$_POST['pippin_redirect']));
            exit;
        }
    }
