If it is a category page,you can get id of current category by:

<pre><code>$category = get_category( get_query_var( 'cat' ) );
$cat_id = $category-&gt;cat_ID;
</code></pre>

If you want to get category id of any particular category on any page, try using : 

<pre><code>$category_id = get_cat_ID('Category Name');
</code></pre>

I use the get_queried_object function to get the current category on a category.php template page.

<pre><code>$current_category = get_queried_object();
</code></pre>

Jordan Eldredge is right, get_the_category is not suitable here.

blocks|key|683578|text|我认为上面的一些方法可能会起作用，但使用get_the_category函数似乎很棘手，可能会产生意想不到的结果。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|683579|我认为在分类页面中访问猫ID的最直接、最简单的方法是：|683580|$wp_query->query_vars['cat']|code-block|syntax|javascript|683581|干杯|683582|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|N|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|O|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|P|8|@]|9|@]|A|$]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

I think some of the above may work but using the get_the_category function seems tricky and may give unexpected results.

I think the most direct and simple way to access the cat ID in a category page is:

<pre><code>$wp_query-&gt;query_vars['cat']
</code></pre>

if you need the category ID, you would get it via <a href="https://developer.wordpress.org/reference/functions/get_query_var/" rel="nofollow noreferrer">get_query_var</a>, that is capable of retrieving all publicly queryble variables.

<pre><code>$category_id = get_query_var('cat');
</code></pre>

here is an example to get the category name

<pre><code>$category_name = get_query_var('category_name');
</code></pre>

and of course the all mighty <a href="https://developer.wordpress.org/reference/functions/get_queried_object/" rel="nofollow noreferrer">get_queried_object</a>

<pre><code>$queried_object = get_queried_object();
</code></pre>

that is returning the complete taxonomy term object (when used on a taxonomy-archive page..)

I found this question whilst looking for exactly what you asked. Unfortunately you have accepted an incorrect answer. For the sake of other people who are trying to achieve what we were trying to achieve, I thought I'd post the correct answer.

<pre><code>$cur_cat = get_cat_ID( single_cat_title("",false) );
</code></pre>

As you said <code>single_term_title("", false);</code> was correctly returning the category title, I'm not sure why you would have had troubles with your code; but the above code works flawlessly for me.

 $categories = get_the_category();

 $custom_category_link = '';
 
 foreach ($categories as $category) {
 if($category-&gt;category_parent == $uncategorised_id || $category-&gt;cat_ID == $uncategorised_id) {
 continue;
 }
 
 $custom_category_link = get_category_link($category-&gt;cat_ID); ?&gt;
 
 &lt;a href =&quot;&lt;?php echo $custom_category_link ?&gt;&quot;&gt; 
 &lt;?php echo &quot;\n\nCategory ID: &quot; . $category-&gt;cat_ID . &quot;\nCategory Name&quot; . $category-&gt;name; ?&gt; &lt;/a&gt;
