Affichage des dimensions

Bonjour,
J'ai modifié le fichier show.php afin d'obtenir un affichage des dimensions de l'objet.
Tout fonctionne parfaitement mais j'aimerais que ces dimensions s'affichent uniquement aux objets auquel j'indique une valeur autre que 0
Merci d'avance pour votre aide !

la partie modifiée:
<span id="hikashop_product_volume_main" class="hikashop_product_volume_main">
<?php echo JText::_('PRODUCT_WIDTH').': '.($this->element->product_width).' '.$this->element->product_dimension_unit; ?><br />
<?php echo JText::_('PRODUCT_LENGTH').': '.($this->element->product_length).' '.$this->element->product_dimension_unit; ?><br />
<?php echo JText::_('PRODUCT_HEIGHT').': '.($this->element->product_height).' '.$this->element->product_dimension_unit; ?></sup>
</span>

Merci pour la rapidité !
je passes effectivement par le menu vues pour modifier le fichier show.php mais le code suivant ne donne pas le résultat escompté.

<span id="hikashop_product_volume_main" class="hikashop_product_volume_main">
<?php if(!empty($this->element->product_width)) echo JText::_('PRODUCT_WIDTH').': '.($this->element->product_width).' '.$this->element->product_dimension_unit; ?>
<?php if(!empty($this->element->product_length)) echo JText::_('PRODUCT_LENGTH').': '.($this->element->product_length).' '.$this->element->product_dimension_unit; ?>
<?php if(!empty($this->element->product_height)) echo JText::_('PRODUCT_HEIGHT').': '.($this->element->product_height).' '.$this->element->product_dimension_unit; ?>
</span>

Est-ce que ce code est juste ?

Super ! merci infiniment et bravo pour le support
