Hi,

im stuck at getting the thumbnail of a image field into my template.

<?php
	$attachment_id = the_field('bild_startseite_boxen');
	$size = "baumann-thumb-big"; // (thumbnail, medium, large, full or custom size)
	$image = wp_get_attachment_image ($attachment_id, $size);
 	?>
	<?php 
    $rows = get_field('boxen_startseite');
    if($rows) {
 
        foreach($rows as $row) {
            // retrieve size 'large' for background image 
         	$output  = "<a href=". $row['derlink'] ."\n";
            $output .= "<li style='list-style-type:none'>\n";
            $output .= "  <div class='threecol boxes-start'>\n";
          
            $output .= "  <h3>". $row['uebeschrift'] ."</h3>\n";
            $output .= "  <img class='nojump' src=". $image[0] ."></img>";
            $output .= "  <p>" . $row['text_startseite_boxen'] . "</p>";
            $output .= "  <p style='color:#F36C3C;margin-top:0;'>mehr...</p>\n";
            $output .= "  </div>\n";
            $output .= "  </li>\n\n";
            $output .= "  </a>\r\n\n";
 
            echo $output;
        } 
    }
    ?>

I know it’s an old question and you’ve probably figured this out by now, at least I hope so, but for anyone else that has a similar question.

The main problem with the above code is the first line

$attachment_id = the_field('bild_startseite_boxen');

the_field() echos the value, when you want to put the value into a variable you must use get_field()

$attachment_id = get_field('bild_startseite_boxen');
