尝试此函数，确保在数组中添加您的短代码

// (OPT) STOP SHORTCODES THAT DON\'T USE INLINE CONTENT FROM BEING WRAPPED IN A P TAG (until WP fixes this)

// ** NOTE -> BE SURE TO change the array to the shortcodes you are using!

add_filter(\'the_content\', \'the_content_filter\');
function the_content_filter($content) {
    // array of custom shortcodes requiring the fix
    $block = join("|",array( \'shortcode_name\' ));
    // opening tag
    $rep = preg_replace("/(<p>)?\\[($block)(\\s[^\\]]+)?\\](<\\/p>|<br \\/>)?/","[$2$3]",$content);
    // closing tag
    $rep = preg_replace("/(<p>)?\\[\\/($block)](<\\/p>|<br \\/>)?/","[/$2]",$rep);
    return $rep;
}

根据@nickfmc的评论，这里是最新WordPress的修订版本，它在过滤器上使用了正确的优先级，并且还修复了regex的一些问题。

注意：最好将每个块格式的短代码保留在自己的行上（WYSIWYG编辑器中的单独段落）。

<?php

add_filter(\'the_content\', function ($content) {
    $blocks = \'columns|column\';

    $replace = [
        "/(?:<p>)?\\[($blocks)(\\s[^\\]]+)?\\](?:<\\/p>|<br\\s*\\/?>)?/" => \'[$1$2]\',
        "/(?:<p>)?\\[\\/($blocks)\\](?:<\\/p>|<br\\s*\\/?>)?/" => \'[/$1]\',
    ];

    return preg_replace(array_keys($replace), array_values($replace), $content);
}, \'10.1\');
