    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().'" />';
?>
