echo something inside a shortcode

Question

I'm a frontender, so i'm not so used to work with php. But I need to solve something. I'm adding a shortcode within the single-product template, and inside this shortcode, I need to echo the slug from the product.

I've tried multiple things, but I cant get it to work.

<?php 
    global $post;
    $post_slug = $post->post_name;
    echo $post_slug;
    echo do_shortcode('[sc name=" I NEED TO ECHO THE POST SLUG HERE "]');
?>

Maybe some of you, could help me out :)

Best regards, Michael

There are a few to do this:

Using double quotes

Don't forget to escape the double quotes inside the string.

global $post;
echo do_shortcode("[sc name=\"$post->post_name\"]");

Using sigle quotes

global $post;
echo do_shortcode("[sc name='$post->post_name']");

Using sprintf

global $post;
echo do_shortcode(
  sprintf('[sc name="%s"]', $post->post_name)
);

Using wp_sprintf

global $post;
echo do_shortcode(
  wp_sprintf('[sc name="%s"]', $post->post_name)
);

Using heredoc

do_shortcode(
    <<< EOF
[add_to_cart_url id="$post->post_name"]
EOF
);
