Hi Dario,
a few weeks ago i fix it myself with the errors about the image and Google Structured Data with the microdata.
Maybe you are interested in the code? If so then i would mail it to you. I just get the first image in a post/page and take this one with the resolution 40×40 and it is shown under the average-rating. Take a look here:
https://www.all4hardware4u.de/platinenherstellung/platine-aetzen/aetzgeraet-selber-bauen/
If there isn’t any image in the page/post i have a fallback with an “no-image-available”-image and everything is fine with Google;)
The code is like this and its put in the yasr-functions.php:
$attachments = get_children( array('post_parent' => get_the_ID(), 'post_type' => 'attachment', 'post_mime_type' => 'image') );
foreach ( $attachments as $attachment_id => $attachment ) {
$bild=array(wp_get_attachment_image($attachment_id));
}
if(!empty($bild[0]))
{
$bild_neu=$bild[0];
$tag_h1 = 'height="';
$tag_h2 = '" ';
$bild_neu = preg_replace("#".$tag_h1.".*".$tag_h2."#Uis", "", $bild_neu);
$tag_w1 = 'width="';
$tag_w2 = '"';
$bild_neu = preg_replace("#".$tag_w1.".*".$tag_w2."#Uis", 'width="130"', $bild_neu);
$anfang = '<img itemprop="image" width="40" height="40" ';
$src = substr($bild_neu,(strpos($bild_neu, 'src="')+5), ((strpos($bild_neu, '" class'))-(strpos($bild_neu, 'src="')+5)));
$endung = substr($src, -4, 4);
$src = substr($src, 0, -4);
$pos = strripos($src, '-');
$laenge = strlen($src);
$src = substr($src, -$laenge, $pos); #!!!!!
$src = $src.'-40x40';
$src_ohne = str_replace('https://www.all4hardware4u.de','.',$src);
$quelle = $src_ohne.$endung;
$src='src="'.$src.$endung.'" ';
$class = 'class="attachment-thumbnail" ';
$alt = substr($bild_neu,(strpos($bild_neu, 'alt="')+5), ((strpos($bild_neu, '" />'))-(strpos($bild_neu, 'alt="')+5)));
$alt = 'alt="'.$alt.'"';
$ende = ' />';
$bild_neu2=$anfang.$src.$class.$alt.$ende;
if(!file_exists($quelle))
{
$bild_neu2=$bild_neu;
}
unset($bild[0]);
}
else
{
$bild_neu2='<img itemprop="image" width="40" height="40" class="attachment-thumbnail" alt="no image" src="https://www.all4hardware4u.de/wp-content/themes/aggregate/images/no_image-40x40.png" />';
}
Best regards,
Harry
