这是一个短代码示例。

[a][b]something[/b][/a]

它应该像这样与do\\u shortcode（$content）一起使用；

function a_shortcode($atts = [], $content = null) {

    do_shortcode($content);

    return $result;

}

add_shortcode(\'a\', \'a_shortcode\');

function b_shortcode($atts = [], $content = null) {

    return $whatever;

}

add_shortcode(\'b\', \'b_shortcode\');

有没有理由不使用没有do\\u shortcode的内容？

  [a][b]something[/b][/a]

function a_shortcode($atts = [], $content = null) {

    //use content here, parse [b]something[/b] as string and do whatever

    return $result;

}

function a_shortcode($atts = [], $content = null) {

    //use content here, parse [b]something[/b] as string and do whatever
    $result = \'<div>\'. $content .\'</div>\';
    return $result;

}
