Fehler in Rocksolid-Template: non-numeric value encountered (PHP 7.1)

[Nina]

Ich hab das nachfolgende Template gebaut und erhalte im Backend nun unter Contao 4.4 immer die Meldung:

Warning: A non-numeric value encountered in /www/htdocs/XXX/templates/da-theme/rsce_service.html5 on line 10
0

Warning: A non-numeric value encountered in /www/htdocs/XXX/templates/da-theme/rsce_service.html5 on line 11

Warning: A non-numeric value encountered in /www/htdocs/XXX/templates/da-theme/rsce_service.html5 on line 21

Hat jemand einen Tipp, wo ich den Fehler reingeschmissen habe?

Und eine rudimentäre rsce_service.html5 zum Testen:

<!-- rsce_service.html5 -->
<section class="solution-area <?php echo $this->class ?> block"<?php echo $this->cssID ?>>
  <div class="container">
    <div class="row">

      <?php foreach ($this->services as $service): ?>
      <div class="col-md-4">
        <div class="single-solution-item">
          <div class="title-holder">
            <h3><?php echo $service->service-title ?></h3>
            <h4><?php echo $service->service-subtitle ?></h4>
            <p>

              <?php if ($image = $this->arrData['getImageObject']($service->image, array(120, 120))): ?>
				<img src="<?php echo $image->src ?>" alt="<?php echo $image->alt ?: $service->service-title ?>"<?php echo $image->imgSize ?>>
              <?php endif ?>


              <?php echo $service->service-shortdesc ?><br>

             <?php echo $service->service-link ?>
           </p>

          </div>
        </div>
      </div>
      <?php endforeach ?>

    </div>
  </div>
</section>

[Spooky]

Du solltest keine Bindestriche in deinen Feldnamen verwenden, da diese Feldnamen dann zu Variablennamen von Objekten werden - und Bindestriche sind in Variablennamen nicht erlaubt.

Außerdem kannst du statt

$image = $this->arrData['getImageObject']($service->image, array(120, 120)) 

$image = $this->getImageObject($service->image, array(120,120,'proportional')) 

verwenden.

Danke, doofer Fehler meinerseits
