Multiple if statements with else for get_the_category [closed]

by

That’s not how you chain multiple conditions with an if statement. Try this

<ul>
    <?php foreach ($categories as $category) { ?>
        <?php if ($category->name !== 'Slides' && $category->name !== 'Uncategorized') { ?>
            <li><?php echo $category->name; ?></li>
        <?php } else { ?>
            <li>Unknown</li>
        <?php } ?>
    <?php } ?>
</ul>
