I have the following code
<table>
<tr><td>
<span id="hikashop_product_height_main" class="hikashop_product_height_main">
<?php echo '<strong>Height: </strong></td><td> '.($this->element->product_height).' '.$this->element->product_dimension_unit; ?>
</span></td></tr>
<tr><td>
<span id="hikashop_product_width_main" class="hikashop_product_width_main">
<?php echo '<strong>Width: </strong></td><td> '.($this->element->product_width).' '.$this->element->product_dimension_unit; ?>
</span></td></tr>
<tr><td>
<span id="hikashop_product_length_main" class="hikashop_product_length_main">
<?php echo '<strong>Depth: </strong></td><td> '.($this->element->product_length).' '.$this->element->product_dimension_unit; ?>
</span></td></tr>
<tr><td> </td></tr>
<tr><td>
<span id="hikashop_product_length_main" class="hikashop_product_length_main">
<?php echo '<strong>Weight: </strong></td><td> '.($this->element->product_weight).' '.$this->element->product_weight_unit; ?>
</span></td></tr>
</table>
displaying the dimension on the product_show view like this
What changes would I need to make to stop displaying these properties when their value is zero?
