Thanks again for your help. I am pretty new with all this.
I have now tried around several attempts, but I still get an error:
Parse error: syntax error, unexpected ‘false’ (T_STRING), expecting ‘)’ in (…)/wp-content/plugins/oxygen/component-framework/components/classes/code-block.class.php(115) : eval()’d code on line 2
<?php if( get_field('dokumente_datei') ):
$file_id = intval(get_field('dokumente_datei', false false));
$image = get_attachment_image_src($file_id, 'thumbnail');
?>
<img src="<?php echo esc_attr($image); ?>" />
<?php endif; ?>
Your help is highly appreciated!
