您可以尝试将其添加到函数中。php文件：

<?php
    function my_formatter($content) {
    $new_content = \'\';
    $pattern_full = \'{(\\[raw\\].*?\\[/raw\\])}is\';
    $pattern_contents = \'{\\[raw\\](.*?)\\[/raw\\]}is\';
    $pieces = preg_split($pattern_full, $content, -1, PREG_SPLIT_DELIM_CAPTURE);

    foreach ($pieces as $piece) {
        if (preg_match($pattern_contents, $piece, $matches)) {
            $new_content .= $matches[1];
        } else {
            $new_content .= wptexturize(wpautop($piece));
        }
    }

    return $new_content;
}

remove_filter(\'the_content\', \'wpautop\');
remove_filter(\'the_content\', \'wptexturize\');

add_filter(\'the_content\', \'my_formatter\', 99);
?>
