Hi!

I like to create a custom loop to show custom post filterd by a custom field (checkbox). This works fine if a add the value for the custom field inside the code. This example works fine:

<?php 
// args
$args = array(
	'post_type' => 'produktark',
        'posts_per_page' => -1,
        'meta_query' => array(
               array(
               'key'       => 'produkttyp',
                'compare'   => 'LIKE',
                'value'     => 'graveskuffer' 
            )
	)
);
					 
// get results
$the_query = new WP_Query( $args );
					 
// The Loop
?>
											 

But i like to choose the value via a custom post field inside the page. So i can select on a page, witch custom posts filted by value i like to show. This custom field is also a checkbox on the page-admin. And now i try this:

<?php 
// args
					
$args = array(

'post_type' => 'produktark',
'posts_per_page' => -1,
'meta_query' => array(
           array(
               'key'       => 'produkttyp',
               'compare'   => 'LIKE',
                'value'     => the_field('vis_produktark_fra') 
                )
)
);
					 
// get results
$the_query = new WP_Query( $args );
					 
// The Loop
?>
											 

And it doesnt´t work. How can i use a custom field (checkbox) on page to create a custom loop filterd by a custom field value?

Thanks for help!

Hello, I have the same probleme.
Someone knows how to solve this, can’t find anything.

I apologize in advance if I’m not understanding your question correctly.

So you have a custom post type (produktark) with a checkbox field in it. Then on another page, you have a ACF to select which checkbox value from the CPT you want to query by?

Assuming that vis_produktark_fra is the field key for the field on the page you want to display the custom posts on, then you should be able to use get_field() rather than the_field(). the_field echos the value, which you don’t want to do.

So assuming I’m understanding you correctly, your code could look like:

<?php 

$vis_produktark_fra = get_field('vis_produktark_fra');
// args
					
$args = array(

'post_type' => 'produktark',
'posts_per_page' => -1,
'meta_query' => array(
           array(
               'key'       => 'produkttyp',
               'compare'   => 'LIKE',
                'value'     =>  $vis_produktark_fra
                )
)
);
					 
// get results
$the_query = new WP_Query( $args );
					 
// The Loop
?>

OR

<?php 

// args
					
$args = array(

'post_type' => 'produktark',
'posts_per_page' => -1,
'meta_query' => array(
           array(
               'key'       => 'produkttyp',
               'compare'   => 'LIKE',
                'value'     =>  get_field('vis_produktark_fra')
                )
)
);
					 
// get results
$the_query = new WP_Query( $args );
					 
// The Loop
?>

this is basically the same thing in my first code snipped
