WordPress主题实现前台用户重置密码功能

PetitQ WordPress教程 2019-1-03 2.04K 0 0

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));

```
	}
```
```
}
```
