Examples

Store the ID

The ID can be stored as a variable using %%% <?php $postid = get_the_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 the ID is not called within PHP, then we can use the_ID rather than echo get_the_ID();
