Related posts, wordpress query - php

Question

The theme that I have been using for my wp site has related posts shortcode which works, but it doesn't hide the currently viewed post. I had some idea to add a variable before the query to a post so the query sees that post which is currently viewed has that variable set to true and skip it. Here is the code:
<?php
global $post;
$categories = get_the_category();
$ceker=false;
foreach ($categories as $category[0]) {
if ($ceker == false){
$ceker=true;
?>
content etc...
I use this in my own themes and it works. How can I do something similar to these shortcode that this theme uses:
#BLOG LIST...
if(!function_exists('dt_blog_posts')) {
function dt_blog_posts( $atts, $content = null ) {
extract(shortcode_atts(array(
'show_feature_image' => 'true',
'excerpt_length' => 35,
'show_meta' => 'true',
'limit' => -1,
'categories' => '',
'posts_column' => 'one-column', // one-column, one-half-column, one-third-column
), $atts));
global $post;
$meta_set = get_post_meta($post->ID, '_tpl_default_settings', true);
$page_layout = !empty($meta_set['layout']) ? $meta_set['layout'] : 'content-full-width';
$post_layout = $posts_column;
$article_class = "";
$feature_image = "";

Answer 1

Answer was simple. Just added
'post__not_in' => array( get_the_ID() ))
in array.
Thx all...
