开源欣赏wordpress之用户新增user-new.php

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。

 

复制代码
$user_details = null;
    if ( false !== strpos($_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();
        }
    }
复制代码

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。

 

复制代码
// 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' );
    }
复制代码

进行用户已存在验证。

 

复制代码
$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' );
复制代码

通过验证,各种欢迎。

 

复制代码
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.');
    }
}
复制代码

消息提示,分类提示,很有意思。貌似这个也是封装好的内容。

复制代码
<?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; ?>
复制代码

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。

 

复制代码
<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>

    </tr>
<?php if ( !is_multisite() ) { ?>
    <tr class="form-field">

    </tr>

        <td><input name="last_name" type="text" id="last_name" value="<?php echo esc_attr($new_user_lastname); ?>" /></td>
    </tr>
    <tr class="form-field">

        <td><input name="url" type="text" id="url" class="code" value="<?php echo esc_attr($new_user_uri); ?>" /></td>
    </tr>
<?php
/**

if ( apply_filters( 'show_password_fields', true ) ) : ?>
    <tr class="form-field form-required">
        <th scope="row"><label for="pass1"><?php _e('Password'); ?> <span class="description"><?php /* translators: password input field */_e('(required)'); ?></span></label></th>

        </td>
    </tr>
    <tr class="form-field form-required">

        <td>
        <input name="pass2" type="password" id="pass2" autocomplete="off" />
        <br />
        <div id="pass-strength-result"><?php _e('Strength indicator'); ?></div>
        <p class="description indicator-hint"><?php _e('Hint: The password should be at least seven characters long. To make it stronger, use upper and lower case letters, numbers and symbols like ! " ? $ % ^ &amp; ).'); ?></p>
        </td>
    </tr>
    <tr>
        <th scope="row"><label for="send_password"><?php _e('Send Password?') ?></label></th>
        <td><label for="send_password"><input type="checkbox" name="send_password" id="send_password" <?php checked( $new_user_send_password ); ?> /> <?php _e('Send this password to the new user by email.'); ?></label></td>
    </tr>
<?php endif; ?>
<?php } // !is_multisite ?>
    <tr class="form-field">
        <th scope="row"><label for="role"><?php _e('Role'); ?></label></th>
        <td><select name="role" id="role">
            <?php
            if ( !$new_user_role )
                $new_user_role = !empty($current_role) ? $current_role : get_option('default_role');
            wp_dropdown_roles($new_user_role);
            ?>
            </select>
        </td>
    </tr>
    <?php if ( is_multisite() && is_super_admin() ) { ?>
    <tr>
        <th scope="row"><label for="noconfirmation"><?php _e('Skip Confirmation Email') ?></label></th>
        <td><label for="noconfirmation"><input type="checkbox" name="noconfirmation" id="noconfirmation" value="1" <?php checked( $new_user_ignore_pass ); ?> /> <?php _e( 'Add the user without sending them a confirmation email.' ); ?></label></td>
    </tr>
    <?php } ?>
</table>
复制代码

验证页面的表单设计。

 

复制代码
<?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' );
复制代码

一些尾文件的引入。

 

很有意思。php还可以这么玩。
