Question

使用WordPress PHP模板 - 我在做一个if语句来检查用户是否已登录，如果他是，那么我想要显示一个电子邮件表单，如果他不是，我想让用户登录。

<?php if ( is_user_logged_in() ) {
    <div role="tabpanel" class="tab-panel active" id="nomessage">
        <div class="row">
            <div class="col-lg-12">
                <h4>You have to be <a href="/login/" target="_blank">logged in</a> to send a message</h4>
            </div>
        </div>
    </div>
} else {
    <div class="tab-content">
    <?php if($classieraToAuthor == 1){?>
    <div role="tabpanel" class="tab-pane active" id="message">
    <!--ShownMessage-->
    <?php if(isset($_POST['submit']) && $_POST['submit'] == 'send_message'){?>
        <div class="row">
            <div class="col-lg-12">
                <?php if($hasError == true){ ?>
                <div class="alert alert-warning">
                    <?php echo $errorMessage; ?>
                </div>
                <?php } ?>
                <?php if($emailSent == true){ ?>
                <div class="alert alert-success">
                    <?php echo $classieraContactThankyou; ?>
                </div>
                <?php } ?>
            </div>
        </div>
        <?php } ?>

                <div class="col-sm-9">
                    <textarea id="msg" name="comments" class="form-control" placeholder="<?php esc_html_e('Type Message', 'classiera') ?>" required></textarea>
                </div>

            <?php

            <div class="form-group">
                <div class="col-sm-9">

                    <?php esc_html_e("Please input the result of ", "classiera"); ?>
                    <?php echo $classieraFirstNumber; ?> + <?php echo $classieraLastNumber;?> =

                    <input type="hidden" name="humanAnswer" id="humanAnswer" value="<?php echo $classieraNumberAnswer; ?>" />
                    <input type="hidden" name="classiera_post_title" id="classiera_post_title" value="<?php the_title(); ?>" />
                    <input type="hidden" name="classiera_post_url" id="classiera_post_url" value="<?php the_permalink(); ?>"  />
                </div>
            </div><!--answer-->
            <input type="hidden" name="submit" value="send_message" />
            <button class="btn btn-primary btn-block btn-sm sharp btn-style-one" name="send_message" value="send_message" type="submit"><?php esc_html_e( 'Send Message', 'classiera' ); ?></button>
        </form>
    </div>
};
?>

首先，我添加了一个if语句来检查用户是否已登录，如果他是第一个显示的元素，则告诉用户必须登录才能发送消息。然后，如果他已登录，则显示消息表单。无法让它工作，会感激所有帮助很多！提前谢谢！

你不能像这样混合PHP和HTML。在编写HTML之前，您已经缺少关闭PHP标记?>。

编辑正如@mmm所指出的，您的测试与您想要的相反。您必须使用字符!否定您的测试。

试试这个：

<?php if ( ! is_user_logged_in() ) : ?>
    <div role="tabpanel" class="tab-panel active" id="nomessage">
        <div class="row">
            <div class="col-lg-12">
                <h4>You have to be <a href="/login/" target="_blank">logged in</a> to send a message</h4>
            </div>
        </div>
    </div>
<?php else: ?>
    <!-- other HTML -->
<?php endif; ?>

或者：

<?php if ( is_user_logged_in() ) { ?>
    <div role="tabpanel" class="tab-panel active" id="nomessage">
        <div class="row">
            <div class="col-lg-12">
                <h4>You have to be <a href="/login/" target="_blank">logged in</a> to send a message</h4>
            </div>
        </div>
    </div>
<?php } else { ?>
    <!-- other HTML -->
<?php } ?>

如果在wordpress中的PHP模板中声明
