Hi.

i have 3 sidebars (siebar-1, sidebar-2, sidebar-3)

on page.php i have the following code: (here the sidebar should load)

...
	<div class="col-lg-3 col-lg-offset-1">
		<?php 
		$sidebar = get_field('sidebar');
		dynamic_sidebar($sidebar);
		?>
	</div>
...

for pages i have the following acf: (return value)

Checkbox field with this options:

sidebar-1 : Sidebar Strom
sidebar-2 : Sidebar Gas
sidebar-3 : Sidebar Wärme

And i got the following error (frontend):
Warning: preg_match() expects parameter 2 to be string, array given in /wp-includes/formatting.php on line 1515

Warning: strip_tags() expects parameter 1 to be string, array given in /wp-includes/formatting.php on line 1967

Can not find my fault.

Looking at this I would guess that you’re returning “Both (Array)”. You need to either set the field to only return the value or use

$sidebar = get_field('sidebar');
dynamic_sidebar($sidebar['value']);

the checkbox field returned “value” but it doesnt work either…

Maybe because the snippet on page.php is outside the loop?

<div class="row">
	<div class="col-lg-8 content-area">
		<main id="main" class="site-main">

			<?php
			while ( have_posts() ) : the_post();

				get_template_part( 'template-parts/content', 'page' );

			endwhile; // End of the loop.
			?>

		</main><!-- #main -->
	</div>
	<div class="col-lg-3 col-lg-offset-1">
		<?php 
		$sidebar = get_field('sidebar');
		dynamic_sidebar($sidebar);
		?>
		test
	</div>
</div>

More than likely, yes, you will need to get the post id and supply that in the ACF function. If this is on a single post template then it’s not too hard

// get the current post id
$queried_object = get_queried_object();
$post_id = $queried_object->ID;

then when you get the field

$sidebar = get_field('sidebar', $post_id);

The Answer:

I have put the Code inside the page loop and i have to change the code a little bit because the field type is checkbox…

<?php

	$sidebars = get_field('sidebar');

	if( $sidebars ): 
		?>
		
			<?php foreach( $sidebars as $sidebar ): ?>
				
					<?php dynamic_sidebar($sidebar); ?>
				
			<?php endforeach; ?>
	<?php endif; ?>
