Here is my situation:
I want to let some users have some capability temporary when they choose some option.
So,I use this code:

function author_cap_filter( $allcaps, $cap, $args ) {
	global $current_user;
	
	if( the_field('is_tw')=="true" )  //"is_tw" is the custome field I set in ACF.
	{	
		global $post;
		$id = $post->ID;
		$status = get_post_status($id);
		
		$allcaps['publish_posts'] = 0; //This is the limitation of diable the ability of publishing post temporary.
	}

	return $allcaps;

}
add_filter( 'user_has_cap', 'author_cap_filter', 10, 3 );

However,it’s useless.Can somebody tell me how to fix this?

I found the solution,just use the get_field().
<?php $field = get_field($field_name, $post_id, $format_value); ?>
