php generate links to all wordpress categories

Im having a little problem. I want to display all categories connected to a wordpress post.

I found several codes and plugins, but all of them have problems. Some dont display correct anchor text, others dont link to correct url. So i took the working parts from different places and put them together to the code below, and its working. The problem is that it does not generate links to ALL connected categories, it only show link to 1 single category (first one that was connected to the post)

what is wrong with the code ? Why will it not show links to all connected categories. I have been working on it for 2 days now, and i give up.

<?php
$the_cat = get_the_category();
$category_name = $the_cat[0]->cat_name;
$category_link = get_category_link( $the_cat[0]->cat_ID );
?>
<?php 
global $post;
$category = reset(get_the_category($post->ID));
$category_id = $category->cat_ID;
?>
<a class="button" href="<?php echo get_category_link( $category_id ); ?>"title=”<?php echo $category_name ?>”  ><?php echo $category_name ?></a>

Actually just <?php the_category(', ') ?> should be enough (within the WP while loop). The , determines what should go in-between, if there is more than one category.

If you want to show the category that is related with the posts on post details page and archive page add this code in your child theme functions.php and call the function where you want to display it.

function postsCategories()
{
    $categories_list = get_the_category_list( esc_html__( ', ', 'your-text-domain' ) );
    $allowed_tags_before_after=array('span' => array('class'=>array()),'i'=>array('class'=>array()),'a'=>array('class'=>array(),'href'=>array(),'rel'=>array()));

        if ( $categories_list )
        {
                printf(wp_kses(sprintf(__('<span class="blogmeta cat-links"> <i class="fa fa-folder-open"></i> %1$s </span>','your-text-domain'), $categories_list ),$allowed_tags_before_after)); 
        }
}

Call in the template : <?php printf(__('%s','your-text-domain'),postsCategories()); ?>

Please try this code 

<?php
$category_args_query = array(
'orderby' => 'name',
'parent' => 0,
'hierarchical'  => 1,
'number'=> 10
);
$categories = get_categories( $category_args_query );?>
<ul>
    <?php 
    foreach ( $categories as $category ) 
    { ?>
        <li><a href="<?php echo get_category_link($category->term_id ); ?> "><?php echo $category->name;  ?> </a></li> 
        <?php 
    }
    ?>
</ul>
