使用php echo显示图像时，Firefox和Explorer的行为有所不同

Question

The image box on this page " http://www.ebookfetcher.com/bookdeals/index.php?pid=23 " appears in Firefox and Explorer, but not Chrome and Safari. How do I make it invisible for all of them when $bookpage_coverimage is empty?

<a href="http://www.ebookfetcher.com" class="linkstyle"><img src="<?php echo $bookpage_coverimage ?>" width="260"></a>

Answer 1

With a simple if statement in PHP.

<?php if($bookpage_coverimage !=""){ ?><a href="http://www.ebookfetcher.com" class="linkstyle"><img src="<?php echo $bookpage_coverimage ?>" width="260"></a><?php } ?>

Should do the trick, it will not output any html if its empty.
