Question

Sorry, really bad at explaining myself sometimes. Why don’t I start from the beginning.

I have this code:

Posted Under <span class="cat-name">
<?php 
   $category = get_the_category();
   echo $category[0]->cat_name; ?>

I’d like to make sure there’s actually something in $category[0]->cat_name before posting it. So I decided to do an if\isset statement:

<?php 
if (isset($category[0]->cat_name)) echo // This is where I'd put the above code. ?>

I’m just not totally sure how to do it, obviously. I know I’d have to escape the quotes, but even then it doesn’t work. Here’s what I’ve tried:

<?php if (isset($category[0]->cat_name))
     echo "Posted Under <span class=\"cat-name\">
     <?php 
        $category = get_the_category();
        echo $category[0]->cat_name; ?></span>" 
     ?>

But no luck. Any ideas? Is there a better way to achieve this? Thanks in advance.

You can mix HTML and PHP code by spanning the if() across <?php ... ?> blocks. I’ll use a colon instead of braces for readability.

<?php
    $category = get_the_category();
    // let's be extra safe
    if (isset($category[0]->cat_name)):
?>
    Posted Under <span class="cat-name">
        <?php echo htmlspecialchars($category[0]->cat_name) ?>
    </span>
<?php endif ?>
