最近在开发 wordpress 主题过程中，用代码制作了前端用户中心，同时前端用户中心中还需要用户密码重置，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：
- function pippin_change_password_form() {
- global $post;
- 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']) && $_GET['password-reset'] == 'true') { ?>
- <div class="pippin_message success">
- <span><?php _e('Password changed successfully', 'rcp'); ?></span>
- </div>
- <?php } ?>
- <form id="pippin_password_form" method="POST" action="<?php echo $current_url; ?>">
- <fieldset>
- <p>
- <label for="pippin_user_pass"><?php _e('New Password', 'rcp'); ?></label>
- <input name="pippin_user_pass" id="pippin_user_pass" class="required" type="password"/>
- </p>
- <p>
- <label for="pippin_user_pass_confirm"><?php _e('Password Confirm', 'rcp'); ?></label>
- <input name="pippin_user_pass_confirm" id="pippin_user_pass_confirm" class="required" type="password"/>
- </p>
- <p>
- <input type="hidden" name="pippin_action" value="reset-password"/>
- <input type="hidden" name="pippin_redirect" value="<?php echo $redirect; ?>"/>
- <input type="hidden" name="pippin_password_nonce" value="<?php echo wp_create_nonce('rcp-password-nonce'); ?>"/>
- <input id="pippin_password_submit" type="submit" value="<?php _e('Change Password', 'pippin'); ?>"/>
- </p>
- </fieldset>
- </form>
- <?php
- return ob_get_clean();
- }
- // password reset form
- function pippin_reset_password_form() {
- if(is_user_logged_in()) {
- return pippin_change_password_form();
- }
- }
- add_shortcode('password_form', 'pippin_reset_password_form');
- function pippin_reset_password() {
- // reset a users password
- if(isset($_POST['pippin_action']) && $_POST['pippin_action'] == 'reset-password') {
- 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', $_POST['pippin_redirect']));
- exit;
- }
- }
- }
- }
- add_action('init', 'pippin_reset_password');
- if(!function_exists('pippin_show_error_messages')) {
- // displays error messages from form submissions
- function pippin_show_error_messages() {
- if($codes = pippin_errors()->get_error_codes()) {
- echo '<div class="pippin_message error">';
- // Loop error codes and display errors
- foreach($codes as $code){
- $message = pippin_errors()->get_error_message($code);
- echo '<span class="pippin_error"><strong>' . __('Error', 'rcp') . '</strong>: ' . $message . '</span><br/>';
- }
- echo '</div>';
- }
- }
- }
- if(!function_exists('pippin_errors')) {
- // used for tracking error messages
- function pippin_errors(){
- static $wp_error; // Will hold global variable safely
- return isset($wp_error) ? $wp_error : ($wp_error = new WP_Error(null, null, null));
- }
- }
第二步：
在你需要的地方插入：
- [password_form]
