[WORDPRESS] Display thumbnail and link to full image attachment

[asiek]

So I created a Post Type named “textures” and I am trying to display a thumbnail of the texture on the “Textures Page” that will link to it’s full image attachment.
I have a custom meta box set up using the Image uploader.

I tried using this code//
<a href="<?[php] the_attachment_link(); ?>">
<?php $textures_image = get_post_meta($post->ID, 'textures_image', true);
echo wp_get_attachment_image($textures_image, 'thumbnail'); ?>
</a>

The thumbnails were displayed but when I click the image
I get this in the address bar instead with no full sized image//
“http://domain.com/textures/Missing%20Attachment“

So I tried to edit this code from
https://codex.wordpress.org/Function_Reference/the_post_thumbnail//

<?php
if ( has_post_thumbnail()) {
$large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'large');
echo '<a href="' . $large_image_url[0] . '" title="' . the_title_attribute('echo=0') . '" >';
the_post_thumbnail('thumbnail');
echo '</a>';
}
?>

(not knowing what in the world I am actually doing)
and came up with this//
<?php
if ( has_post_thumbnail()) {
$textures_image = get_post_meta($post->ID, 'textures_image', true);
echo '<a href="' . $textures_image[0] . '" title="' . the_title_attribute('echo=0') . '" >';
echo wp_get_attachment_image($textures_image, 'thumbnail');
echo '</a>';
}
?>

Please keep in mind that I have absolutely no clue what I’m doing here…

Any way my question is how can I clean and fix this code to get the thumbnail showing and get the link to work and direct viewers to the full image attachment?

Please Help.

So I found a solution.
At first I wasn’t able to get a featured image metabox working…
But I found a way and got it working in the end.
So I used this in my template//
<?php
if ( has_post_thumbnail()) {
$large_image_url = wp_get_attachment_image_src( get_post_thumbnail_id(), 'large');
echo '<a href="' . $large_image_url[0] . '" title="' . the_title_attribute('echo=0') . '" >';
the_post_thumbnail('thumbnail');
echo '</a>';
}
?>

&that did the trick :)
