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：

1. function pippin_change_password_form() {

2. 	global $post;	

4.    	if (is_singular()) :

5.    		$current_url = get_permalink($post->ID);

6.    	else :

7.    		$pageURL = 'http';

8.    		if ($_SERVER["HTTPS"] == "on") $pageURL .= "s";

9.    		$pageURL .= "://";

10.    		if ($_SERVER["SERVER_PORT"] != "80") $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];

11.    		else $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];

12.    		$current_url = $pageURL;

13.    	endif;		

14. 	$redirect = $current_url;

16. 	ob_start();

18. 		// show any error messages after form submission

19. 		pippin_show_error_messages(); ?>

21. 		<?php if(isset($_GET['password-reset']) && $_GET['password-reset'] == 'true') { ?>

22. 			<div class="pippin_message success">

23. 				<span><?php _e('Password changed successfully', 'rcp'); ?></span>

24. 			</div>

25. 		<?php } ?>

26. 		<form id="pippin_password_form" method="POST" action="<?php echo $current_url; ?>">

27. 			<fieldset>

28. 				<p>

29. 					<label for="pippin_user_pass"><?php _e('New Password', 'rcp'); ?></label>

30. 					<input name="pippin_user_pass" id="pippin_user_pass" class="required" type="password"/>

31. 				</p>

32. 				<p>

33. 					<label for="pippin_user_pass_confirm"><?php _e('Password Confirm', 'rcp'); ?></label>

34. 					<input name="pippin_user_pass_confirm" id="pippin_user_pass_confirm" class="required" type="password"/>

35. 				</p>

36. 				<p>

37. 					<input type="hidden" name="pippin_action" value="reset-password"/>

38. 					<input type="hidden" name="pippin_redirect" value="<?php echo $redirect; ?>"/>

39. 					<input type="hidden" name="pippin_password_nonce" value="<?php echo wp_create_nonce('rcp-password-nonce'); ?>"/>

40. 					<input id="pippin_password_submit" type="submit" value="<?php _e('Change Password', 'pippin'); ?>"/>

41. 				</p>

42. 			</fieldset>

43. 		</form>

44. 	<?php

45. 	return ob_get_clean();	

46. }

48. // password reset form

49. function pippin_reset_password_form() {

50. 	if(is_user_logged_in()) {

51. 		return pippin_change_password_form();

52. 	}

53. }

54. add_shortcode('password_form', 'pippin_reset_password_form');

57. function pippin_reset_password() {

58. 	// reset a users password

59. 	if(isset($_POST['pippin_action']) && $_POST['pippin_action'] == 'reset-password') {

61. 		global $user_ID;

63. 		if(!is_user_logged_in())

64. 			return;

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

68. 			if($_POST['pippin_user_pass'] == '' || $_POST['pippin_user_pass_confirm'] == '') {

69. 				// password(s) field empty

70. 				pippin_errors()->add('password_empty', __('Please enter a password, and confirm it', 'pippin'));

71. 			}

72. 			if($_POST['pippin_user_pass'] != $_POST['pippin_user_pass_confirm']) {

73. 				// passwords do not match

74. 				pippin_errors()->add('password_mismatch', __('Passwords do not match', 'pippin'));

75. 			}

77. 			// retrieve all error messages, if any

78. 			$errors = pippin_errors()->get_error_messages();

80. 			if(empty($errors)) {

81. 				// change the password here

82. 				$user_data = array(

83. 					'ID' => $user_ID,

84. 					'user_pass' => $_POST['pippin_user_pass']

85. 				);

86. 				wp_update_user($user_data);

87. 				// send password change email here (if WP doesn't)

88. 				wp_redirect(add_query_arg('password-reset', 'true', $_POST['pippin_redirect']));

89. 				exit;

90. 			}

91. 		}

92. 	}	

93. }

94. add_action('init', 'pippin_reset_password');

96. if(!function_exists('pippin_show_error_messages')) {

97. 	// displays error messages from form submissions

98. 	function pippin_show_error_messages() {

99. 		if($codes = pippin_errors()->get_error_codes()) {

100. 			echo '<div class="pippin_message error">';

101. 			    // Loop error codes and display errors

102. 			   foreach($codes as $code){

103. 			        $message = pippin_errors()->get_error_message($code);

104. 			        echo '<span class="pippin_error"><strong>' . __('Error', 'rcp') . '</strong>: ' . $message . '</span><br/>';

105. 			    }

106. 			echo '</div>';

107. 		}	

108. 	}

109. }

111. if(!function_exists('pippin_errors')) { 

112. 	// used for tracking error messages

113. 	function pippin_errors(){

114. 	    static $wp_error; // Will hold global variable safely

115. 	    return isset($wp_error) ? $wp_error : ($wp_error = new WP_Error(null, null, null));

116. 	}

117. }

第二步：

在你需要的地方插入：

1. [password_form]
