我刚刚测试了这段代码，它似乎正在工作。虽然正如其他人所说，您在边距底部的末尾缺少一个分号，您可能希望添加该分号以确保语义正确。

话虽如此，为了让代码在输入所见即所得时准确地输出您想要的内容，而不需要额外的p标记包装文本，您应该添加一个过滤器来替换<p> 这样的标签：

/* Shortcode Content Filter */
if ( ! function_exists( \'the_content_filter\' ) ) :
    function the_content_filter($content) {
        $block = join("|",array(\'container\'));
        $rep = preg_replace("/(<p>)?\\[($block)(\\s[^\\]]+)?\\](<\\/p>|<br \\/>)?/","[$2$3]",$content);
        $rep = preg_replace("/(<p>)?\\[\\/($block)](<\\/p>|<br \\/>)?/","[/$2]",$rep);
        return $rep;
    }
    add_filter("the_content", "the_content_filter");
endif;

[container]

Text

[/container]

<div class="container test" style="margin-top:20px; margin-bottom:20px"><section><div class="row"><p></p>
<p>Test</p>
<p>
</p></div></section></div>

我经常做输出缓冲，这对我很有用。让我们看看这个例子。未测试。

和esc_attr() 将处理各种用户输入错误的转义。

<?php
/**
 * Container shortcode
 *
 * Outputs a container wrapping the content.
 * 
 * @param  array $atts     Array of shortcode attributes.
 * @param  string $content Content within a shortcode.
 * @return string          The formatted content.
 */
function wpse_228875_shortcode( $atts, $content ) {

    $atts = shortcode_atts( array(
                \'type\'          => \'\',
                \'margintop\'     => \'\',
                \'marginbottom\'  => \'\',
            ), $atts, \'container\' );

    $type           = isset($atts[\'type\'])          ? $atts[\'type\']         : \'\';
    $margintop      = isset($atts[\'margintop\'])     ? $atts[\'margintop\']    : \'\';
    $marginbottom   = isset($atts[\'marginbottom\'])  ? $atts[\'marginbottom\'] : \'\';

    //start output buffering
    ob_start();
    ?>

    <div class="container <?php echo esc_attr($type); ?>" style="margin-top:<?php echo esc_attr($margintop); ?>; margin-bottom:<?php echo esc_attr($marginbottom); ?>;">
        <section>
            <div class="row">
                <?php
                /**
                 * Using do_shortcode() will allow you
                 * to use another shortcode within the
                 * container shortcode.
                 */
                echo do_shortcode( apply_filters( \'the_content\', $content ) );
                ?>
            </div> <!-- /.row -->
        </section>
    </div> <!-- /.container -->

    <?php
    //cleanup the buffering and return everything within
    return ob_get_clean();

}

add_shortcode( \'container\', \'wpse_228875_shortcode\', 10, 2 );
