require_once( dirname( __FILE__ ) . '/admin.php' );
引入根文件。
if ( is_multisite() ) { if ( ! current_user_can( 'create_users' ) && ! current_user_can( 'promote_users' ) ) wp_die( __( 'Cheatin’ uh?' ) ); } elseif ( ! current_user_can( 'create_users' ) ) { wp_die( __( 'Cheatin’ uh?' ) ); }
用户权限验证，封装在方法当中了。
用户信息输入完后，跳转到列表。是这么个流程。
用户列表有批量操作的多选按钮。同时有新增用户，等管理。
同时可以根据多个条件进行搜索。搜索过程中子页面是跳转的。结果信息直接在头部提示。
我们继续看代码。
$user_details = null; if ( false !== strpos($_REQUEST[ 'email' ], '@') ) { $user_details = get_user_by('email', $_REQUEST[ 'email' ]); } else { if ( is_super_admin() ) { $user_details = get_user_by('login', $_REQUEST[ 'email' ]); } else { wp_redirect( add_query_arg( array('update' => 'enter_email'), 'user-new.php' ) ); die(); } }
一些逻辑验证，方法封装，很多可以具有通用性。比如wp_redirect()就特别具有通用性，一个项目中离不开页面跳转。
这种简洁的页面设计就特别有意思。背景变红，边框变红。
这次的错误提示是提交后，后台反馈的。
很有意思。前后端同时验证。
<div class="error below-h2"> <p><strong>错误</strong>：请填写用户名。</p><p><strong>错误</strong>：此用户名包含无效字符，请输入有效的用户名。</p><p><strong>错误</strong>：电子邮件地址不正确。</p> </div>
这就是html的内容，是在div层中展示出来的。
// Adding an existing user to this blog $new_user_email = $user_details->user_email; $redirect = 'user-new.php'; $username = $user_details->user_login; $user_id = $user_details->ID; if ( ( $username != null && !is_super_admin( $user_id ) ) && ( array_key_exists($blog_id, get_blogs_of_user($user_id)) ) ) { $redirect = add_query_arg( array('update' => 'addexisting'), 'user-new.php' ); }
进行用户已存在验证。
$newuser_key = substr( md5( $user_id ), 0, 5 ); add_option( 'new_user_' . $newuser_key, array( 'user_id' => $user_id, 'email' => $user_details->user_email, 'role' => $_REQUEST[ 'role' ] ) ); $roles = get_editable_roles(); $role = $roles[ $_REQUEST['role'] ]; /* translators: 1: Site name, 2: site URL, 3: role, 4: activation URL */ $message = __( 'Hi, You\'ve been invited to join \'%1$s\' at %2$s with the role of %3$s. Please click the following link to confirm the invite: %4$s' ); wp_mail( $new_user_email, sprintf( __( '[%s] Joining confirmation' ), get_option( 'blogname' ) ), sprintf( $message, get_option( 'blogname' ), home_url(), wp_specialchars_decode( translate_user_role( $role['name'] ) ), home_url( "/newbloguser/$newuser_key/" ) ) ); $redirect = add_query_arg( array('update' => 'add'), 'user-new.php' );
通过验证，各种欢迎。
if ( isset($_GET['update']) ) { $messages = array(); if ( is_multisite() ) { switch ( $_GET['update'] ) { case "newuserconfirmation": $messages[] = __('Invitation email sent to new user. A confirmation link must be clicked before their account is created.'); break; case "add": $messages[] = __('Invitation email sent to user. A confirmation link must be clicked for them to be added to your site.'); break; case "addnoconfirmation": $messages[] = __('User has been added to your site.'); break; case "addexisting": $messages[] = __('That user is already a member of this site.'); break; case "does_not_exist": $messages[] = __('The requested user does not exist.'); break; case "enter_email": $messages[] = __('Please enter a valid email address.'); break; } } else { if ( 'add' == $_GET['update'] ) $messages[] = __('User added.'); } }
消息提示，分类提示，很有意思。貌似这个也是封装好的内容。
<?php if ( isset($errors) && is_wp_error( $errors ) ) : ?> <div class="error"> <ul> <?php foreach ( $errors->get_error_messages() as $err ) echo "<li>$err</li>\n"; ?> </ul> </div> <?php endif; if ( ! empty( $messages ) ) { foreach ( $messages as $msg ) echo '<div id="message" class="updated"><p>' . $msg . '</p></div>'; } ?> <?php if ( isset($add_user_errors) && is_wp_error( $add_user_errors ) ) : ?> <div class="error"> <?php foreach ( $add_user_errors->get_error_messages() as $message ) echo "<p>$message</p>"; ?> </div> <?php endif; ?>
错误信息展示，如果有的话，将div展示出来。这就是前端的逻辑，可以卸载tpl中。
<table class="form-table"> <tr class="form-field form-required"> <th scope="row"><label for="user_login"><?php _e('Username'); ?> <span class="description"><?php _e('(required)'); ?></span></label></th> <td><input name="user_login" type="text" id="user_login" value="<?php echo esc_attr($new_user_login); ?>" aria-required="true" /></td> </tr> <tr class="form-field form-required"> <th scope="row"><label for="email"><?php _e('E-mail'); ?> <span class="description"><?php _e('(required)'); ?></span></label></th> <td><input name="email" type="text" id="email" value="<?php echo esc_attr($new_user_email); ?>" /></td> </tr> <?php if ( !is_multisite() ) { ?> <tr class="form-field"> <th scope="row"><label for="first_name"><?php _e('First Name') ?> </label></th> <td><input name="first_name" type="text" id="first_name" value="<?php echo esc_attr($new_user_firstname); ?>" /></td> </tr> <tr class="form-field"> <th scope="row"><label for="last_name"><?php _e('Last Name') ?> </label></th> <td><input name="last_name" type="text" id="last_name" value="<?php echo esc_attr($new_user_lastname); ?>" /></td> </tr> <tr class="form-field"> <th scope="row"><label for="url"><?php _e('Website') ?></label></th> <td><input name="url" type="text" id="url" class="code" value="<?php echo esc_attr($new_user_uri); ?>" /></td> </tr> <?php /** * Filter the display of the password fields. * * @since 1.5.1 * * @param bool True or false, based on if you want to show the password fields.

验证页面的表单设计。
<?php /** This action is documented in wp-admin/user-new.php */ do_action( 'user_new_form', 'add-new-user' ); ?> <?php submit_button( __( 'Add New User '), 'primary', 'createuser', true, array( 'id' => 'createusersub' ) ); ?> </form> <?php } // current_user_can('create_users') ?> </div> <?php include( ABSPATH . 'wp-admin/admin-footer.php' );
一些尾文件的引入。
很有意思。php还可以这么玩。
