Inside the category.php file I have a custom navbar which is...

<ul class = "nav nav-tabs nav-justified">
                <li><a href="http://example.com/blog/" title="View all posts">All Categories</a></li>
                <?php wp_list_categories('orderby=name&title_li='); ?>
            </ul>

I would like the li for the current category to have class = "active". How can I code this?

Thank you

The current category link has already a special class: current-cat. Why don’t you just use that? –  toscho Feb 8 at 23:42
    
as I am using bootstrap framework which uses active not current. –  ijames55 Feb 8 at 23:43
    
open bootstrap, look at class 'active' and copy it naming if 'current'. Really, it works. –  G. M. Feb 9 at 1:19

You can filter the output on wp_list_categories:

add_filter( 'wp_list_categories', function( $html ) {
    return str_replace( ' current-cat', ' active', $html );
});

If you are stuck with an outdated PHP version … find a better web hosting. In the mean time, you can try this:

add_filter( 'wp_list_categories', 'replace_current_cat_css_class' );

function replace_current_cat_css_class( $html ) {
    return str_replace( ' current-cat', ' active', $html );
}

Sorry for being a noob but where do I put this code?? –  ijames55 Feb 9 at 0:05
    
In your theme’s functions.php. –  toscho Feb 9 at 0:06
    
I'm getting Parse error: syntax error, unexpected T_FUNCTION in /home/a8346489/public_html/wp-content/themes/bootstrap/functions.php on line 9 –  ijames55 Feb 9 at 0:19
    
@ijames55 Your PHP version is very old and insecure. Please do yourself a favor and run an upgrade immediately. My script will work then. –  toscho Feb 9 at 0:26
    
Wow, didn't realise how old it was, I guess free web hosting is free for a reason... Is there any way to get round this? –  ijames55 Feb 9 at 0:28
