Category Color

FAQ

How can I add these colors to my template?

cat_ID;

if(function_exists(‘rl_color’)){
$rl_category_color = rl_color($the_category_id);
}
?>

Now you used the color in your template in an inline stylesheet. The variable <?php echo $category_color; ?> can be used for anything.

How to add colors in single post template?

In your WordPress theme, find the file where you want the color to appear. For instance single.php your single post will be shown. Find these lines:

<?php if (have_posts()) :  ?>
<?php while (have_posts()) : the_post(); ?>

WORDPRESS_EXTRA_CODE_DONT_REMOVE_IT

<?php endwhile; ?>
<?php endif; ?>

Don’t edit or remove the above lines, but add these lines in between instead:

<?php
    $category = get_the_category();
    $the_category_id = $category[0]->cat_ID;

    if(function_exists('rl_color')){
        $rl_category_color = rl_color($the_category_id);
    }
?>
<h1 style="color: #<?php echo $rl_category_color; ?>;"><?php the_title(); ?></h1>
<p style="background: #<?php echo $rl_category_color; ?>;">Awesome Category Color!</p>

How add color in multiple categories?

Add the following code in your .php file, where you want to show the categories name.

<?php
    $categories = get_the_category();
    $separator = ' / ';
    $output = '';
    if($categories){
        foreach($categories as $category) {
                $rl_category_color = rl_color($category->cat_ID);
            $output .= '<a href="'.get_category_link( $category->term_id ).'" style="color:'.$rl_category_color.';">'.$category->cat_name.'</a>'.$separator;
        }
    echo trim($output, $separator);
    }
?>

Why can’t pick a color right away when creating a Category, but only when editing a Category?

Both for consistency and efficiency. First of all WordPress want to keep creating Categories sweet and simple with as little effort as possible. Adding Colors can be considered as customizing Categories, thus it would be more logical to show it in the Edit section only.

Second, when writing a Post you can also quick-add a new category. For consistency’s sake we’d have to add the Colorpicker there too, which would be too much of a hassle user-wise at least.
