Get current category ID of the active page

Tried above for solutions to find cat ID of a post, but nothing worked, used the following instead:


$obj = get_queried_object();
$c_id = wp_get_post_categories($obj->ID);

if you need the category ID, you would get it via [get_query_var][1], that is capable of retrieving all publicly queryble variables.

$category_id = get_query_var('cat');
here is an example to get the category name

$category_name = get_query_var('category_name');

and of course the all mighty [get_queried_object][2]

$queried_object = get_queried_object();
that is returning the complete taxonomy term object (when used on a taxonomy-archive page..)

Here's an efficient method to get category meta data, along with HTML if you want to print it out on the front-end:

```php
<?php

function custom_get_categories() {
$categories = get_the_category();
$uncategorised_id = get_cat_ID('Uncategorized');
$custom_category_link = '';

foreach ($categories as $category) {
if($category->category_parent == $uncategorised_id || $category->cat_ID == $uncategorised_id) {
continue;
}

$custom_category_link = get_category_link($category->cat_ID); ?>

<a href ="<?php echo $custom_category_link ?>">
<?php echo "\n\nCategory ID: " . $category->cat_ID . "\nCategory Name" . $category->name; ?> </a>

<?php
}``
}

?>
```

I tested all these answers and this is the only one which works on all archive page types including posts page.

$category_id = get_the_category( get_the_ID());
$cat_id = get_category($category_id[0]->term_id);
