Creating a Shortcode to Obtain a Post’s ID
Version audio de cet article
With this tutorial, we will create a shortcode that will allow us to fetch the ID of the current post. This shortcode is often referred to as current post id . For example, this can be used to fetch a param and get the value in order to stash it in a form.
We will need to add this shortcode into our functions.php file and will return the current post id.
//[thepostid]
function thepostidfunc( $atts ){
global $post;
return $post->ID;
}
add_shortcode( 'thepostid', 'thepostidfunc' );Puis vous pouvez l’appeler de cette façon :
<?php echo do_shortcode( '[thepostid]' ); ?>
