Question

I want to ask on how to get the link of each category that have related post on it. I only got some code that will only display parent category. Any help would be much appreciated. Thanks!

<?php

$categories = get_categories();

foreach ($categories as $cat){
   if($cat->parent < 1){
      echo $cat->cat_name ;
   }
}

?>

Answer 1

Sounds like you may want get_category_link - something like:

$categories = get_categories();
foreach ($categories as $cat) {
    $category_link = get_category_link($cat->cat_ID);
    echo '<a href="' . esc_url($category_link) . '" title="' . esc_attr($cat->name) . '">' . esc_html($cat->name) . '</a>';
}

should print out the links to the categories for you.

Answer 2

According to Function Reference/get category link

<?php get_category_link( $category_id ); ?> 

Example:

<?php
// Get the ID of a given category
$category_id = get_cat_ID( 'Category Name' );

// Get the URL of this category
$category_link = get_category_link( $category_id );
?>

<!-- Print a link to this category -->
<a href="<?php echo esc_url( $category_link ); ?>" title="Category Name">Category Name</a>
