    Should be noted that if this is ran on the Blog homepage, it instead returns the first listed Post ID instead of the blog homepage ID.

    Post Anchor Identifier
    get_the_ID() can be used to provide a unique anchor in a script. For instance, a dynamically-generated drop down menu with actions for each post in an archive could have

    <?php
    	$id = get_the_ID();
    	$dropdown = "<select name='dropdown-".$id."' >";
    	$dropdown .= "<option id='option1-". $id ."'>Option 1</option>";
    	$dropdown .= "</select>";
    ?>

    This would allow us to use JavaScript to control the element as it has a unique ID, and when submitting it as a form through the POST or GET methods the dropdown box will be sent with a unique ID which allows the script to note which post it is working on. Alternatively a hidden variable could be sent which will allow the script to see which post the submission is referring to

    <?php
    	echo '<input type="hidden" name="activepost" id="activepost" value="'.get_the_ID().'" />';
    ?>

    If you are working with custom post types or you are just not sure if the file you are working in has any direct access to the post, you can try this handy statement to get the ID of a post; outside of the loop even.

    global $post;  
        $post_id = ( empty( $post->ID ) ) ? get_the_ID() : $post->ID;

    Then use $post_id string to assure you have the post ID. Example usage:

    if ( get_post_type( $post_id ) != 'wpbdp_listing' ) return;
