Filter to manipulate the_title AND the_content at the same time

You would need to use the ‘the_content’ filter for content. No way around that. Your filter callback only gets the actual content, not what post it belongs to. If this is intended to work in the main WP loop, you can get the current post from the global $post variable. From that you can get the title or whatever other post data you need.

Thank you, bcworkz!

Unfortunately I’m very new to coding with php and wordpress and I have no idea how I can manipulate the title and post and return it to the_content.

Can you/someone else give me a little hint?

Thanks!

Here’s some pseudo code.

function hidefsk16 ($content) {
        global $post
        $title = $post->title;
	$fsk = substr($title,0,7);
	if ($fsk == "[FSK16]") {
                $title = "Not visible between 6am and 10pm";
		return $title;
	}
	return $content;
}
add_filter('the_content','hidefsk16');

Pseudo code huh? ?? That’s actually quite close!

On a quick read, I think you just need to alter how you address the title.
$title = $post->post_title;

If you still have problems after this change, let me know and I’ll take a closer look. I’m pretty sure you’ll be good with this one change though.

Thanks again, bcworkz!

When I use the following code, the title of the post stays, but the text of the post becomes: “Not visible between 6am and 10pm”

May you have a closer look at it please ??
What I want to do is to alter the title to something like “Youth protection” and the text of the post to something like “The original post is not visible between…. “.

Thank you!

function hidefsk16 ($content) {
        global $post;
        $title = $post->post_title;
	$fsk = substr($title,0,7);
	if ($fsk == "[FSK16]") {
                $title = "Not visible between 6am and 10pm";
		return $title;
	}
	return $content;
}

add_filter('the_content','hidefsk16');

OK, I think I see what’s wrong now. Your code is doing what it’s supposed to do. You still need your original code to manage the title. Title and content are separate distinct entities requiring separate distinct code to alter each.

That said, I now see a way to handle both from ‘the_title’ filter. It’s a bit hacky and I haven’t verified that it’ll work. Personally I’d stick with the two hook solution. You should get the two hook solution working the way you want before exploring the one hook variant, the code is still applicable.

Instead of returning the modified content in ‘the_content’, set $post->post_content to the modified value in ‘the_title’. Being a global, the value should persist until the content is output later inside the loop.

Will try that later.
Thanks a lot!

Okay, I used the 2 filter/hook solution.
Not the best way, but it works ??

Thank you so much!

//when should the warning show up?
$FSKstart = 6;
$FSKend = 22;

//define message for hidden posts
$FSKwarning = "<strong>Diese Beitrag ist aus Gr&uuml;nden des Jugendschutzes nur zwischen 22:00Uhr und 06:00Uhr vollst&auml;ndig zu sehen. <br>Komm bitte sp&auml;ter wieder.</strong>";

//function to remove the [FSK] Tag from title
function hidefsk16_title ($title) {
	$fsk = substr($title,0,5);
	if ($fsk == "[FSK]") {
		$title = substr($title,6);
		return $title;
	}
	return $title;
}

//function to replace article with warning message
function hidefsk16_content ($content) {
	global $post, $FSKstart, $FSKend, $FSKwarning;;

	$hour = date("H",$timestamp);
	$title = $post->post_title;
	$fsk = substr($title,0,5);
	if ($fsk == "[FSK]" && ($hour >=$FSKstart && $hour<=($FSKend-1) )) {
		//$post->post_title = substr($title,7);
		return $FSKwarning;
	}
	return $content;
}

//register the filter hooks
add_filter('the_title','hidefsk16_title');
add_filter('the_content','hidefsk16_content');
