Magento：如何分离多个属性的显示？

Question

I am using this code to display (on the frontend) all assigned attributes of a product in Magento:

<?php if ($_product->getData('metal')): ?>  
    <?php echo nl2br($_product->getResource()->getAttribute('metal')->getFrontend()->getValue($_product )) ?>  
<?php endif; ?>

I need to separate each item with a bullet point • and a break <br/>. How would I edit this code to reflect those changes? Thanks in advance.

Assuming that the above code is "working"... make this change:

<?php echo "&#149;".nl2br($_product->getResource()->getAttribute('metal')->getFrontend()->getValue($_product ))."<br/>" ?>

the . is a string concatenation operator.

Or are you asking how to do it if the above is the HTML of a listing of products? Then this should work...

<?php 
$somehtml=nl2br($_product->getResource()->getAttribute('metal')->getFrontend()->getValue($_product ));
$somehtml=explode("<br />",$somehtml);  // This ASSumes nl2br inserts <br /> between each line and this 
                                        // would lead to the behaviour you want.
                                        // see: http://php.net/manual/en/function.nl2br.php
$somehtml=implode("<br/>
&#149;",$somehtml);
$somehtml="&#149;".$somehtml."<br/>
";
echo $somehtml;
unset($somehtml);
?>

explode makes an array from a string by chopping up the string via the "<br />". implode then rejoins the the string by putting <br/> &#149; between each element. And finally, I add the bullet point to the front and br at the end. When imploding, you still must consider the "outside" of the string.
