WordPress Shortcode - Get post data by ID

I've created a post type name "Gallery" and added some post meta boxes to it. For now, let's say there is a Title and a Content for each single gallery.

now, I want to make a use of that data with Shortcode. How Is this possible?

For example -
[gallery id=x]

I know how to take the value of ID (x), but how do I output a post with the ID of that value?

I register this shortcode like so (but of course it's not completed)

function shortcote_gallery( $atts , $content = null ) {
    extract( shortcode_atts(
        array(
            'title' => 'Default Gallery Title'
        ), $
    return "<h3>$title</h3><p>$content</p>";
}
add_shortcode( 'gallery', 'shortcote_gallery' );

I hope I was clear enough. If not, please let me know so I explain myself better. Thanks in advance.

In your example:

[gallery id=x] has as parameter the field id.

So in your shortcode-function, you need to extract that as well.

function shortcote_gallery( $atts , $content = null ) {
    extract( shortcode_atts(
        array(
            'title' => 'Default Gallery Title',
            'id' => '',
        ), $atts));
    return "<h3>$title</h3><p>$content</p>";
}

You now can do everything you want in the usual php way. $id now has the value you entered in your post. So if you want to output something with this ID, just fire a query to the database and fetch the results you need.

If you have something like this:

global $wpdb;
$results = $wpdb->get_results("SELECT * FROM `myTable` WHERE id ='".$id."'");

Here you go and format the output:

$content = "You have selected ".$results[0]->myField." with the id: $id";
return $content;
