Hey Community,

i have an post-type = “3d_drucker” and a custom-field = “sls”.

I would like to list the printers belonging to this type.
I have an ACF (printer_type).
If “sls” is now entered here, then these should be output separately.

<?php
$args = array(
'post_type' => '3d_drucker',
'posts_per_page' => '10',
'orderby' => 'title',
'order' => 'ASC',
);
$Vergleichstabelle = new WP_Query($args);
if($Vergleichstabelle->have_posts()) : while($Vergleichstabelle->have_posts()) : $Vergleichstabelle->the_post();
?>

<?php 

if( get_field('printer_type') == 'SLS' ) {
    // Do something.
}
	  
	  
	  // Wenn mindestens 1 Datensatz vorhanden ist

// Platzierung aus Feld laden
    $modell = get_field( 'modell' );

// 3D Drucker aus Feld laden
    $hersteller = get_field( 'hersteller' );
    
// 3D Drucker Link aus Feld laden
    $image = get_field( 'image' );    
    
// Listenpreis aus Feld laden
    $aktionspreis = get_field( 'aktionspreis' );  
      
// Amazon Image aus Feld laden
    $amazon_link = get_field( 'amazon_link' );  

// Amazon ALT Image aus Feld laden
    $amazon_alt_image = get_field( 'amazon_alt_image' ); 
    
   echo 

    	

<div class="row">
	<div class="col-lg-4">
		<div class="thumbnail thumbnail-9876 product-grid" style="height:507px">
			<div class="caption">
				<div class="img-grid-wrapper">

					<noscript><img src="$image" />
					</a>
				</div>
				<a href="https://dein-3d.com/3d_drucker/$modell">$hersteller - $modell</a>
				<div class="product-price">
				<p class="price">
					<small>ab</small>
				$aktionspreis	
				</p>
				<small class="price-hint">inkl. 16% gesetzlicher MwSt.</small>
				</div>
				<hr class="hidden-xs">
				<a href="https://dein-3d.com/3d_drucker/$modell" title="$hersteller - $modell">Details</a>
				<a href="$amazon_link" title="$hersteller - $modell" rel="nofollow" target="_blank">Kaufen*</a>
			</div>
		</div>
	</div>
</div>

    

    ?>

<?php endwhile; endif; wp_reset_postdata(); ?>

Sounds like you need to query the posts by custom field, as explained at https://developer.wordpress.org/reference/classes/wp_query/#custom-field-post-meta-parameters (and do a separate query for posts NOT containing the custom field value, or whatever).

Yes that’s right. But it doesn’t work …
with what needs to be heard here?

<?php
  $ad_args = array(
    'post_type'       => '3d_drucker',
    'orderby'         => 'rand',
    'meta_query'      => array(
      array(
        'key'     => '3ddruck-verfahren',
        'value'   => 'SLS',
      )
    )
  );

// query
$ad_query = new WP_Query($ad_args);
?>

Shouldn’t it rather be

  $ad_args = array(
    'post_type'       => '3d_drucker',
    'orderby'         => 'rand',
    'meta_query'      => array(
      array(
        'key'     => 'printer_type',
        'value'   => 'SLS',
      )
    )
  );

(i. e. different key)
Check the field name/slug that you want to query.
