根据我们的讨论，我相信在PHP和MySQL上用代码动态覆盖内容的强度会降低，我会这样做：
<?php
/**

**/
add_filter( \'the_content\', function( $content ) {
global $post;
$custom text = \'blah [blah]\';
/**
* Ignore other post types.
*/
if ( \'custompost\' !== $post->post_type ) {
return $content;
}
/**
* Return the value I want to override with.
*/
return do_shortcode( $custom_text );
} );
