Variable inside shortcode or shortcode inside shortcode

Question

I have a working shortcode, ie like this:

[shortcode_name search="" show="url, color, size"]

In this shortcode if I insert for example an email inside search (search="test@test.com") it displays all entries from that e-mail. If I don't write anything, it displays all entries from all e-mails.

I would like to insert a variable like search="'.$user_email.'" to display all entries of that logged user.

How can I use that variable?

I tried also with a shortcode that generates the e-mail, but how to use a shortcode inside another shortcode? I tried [shortcode_name search="[user_email_shortcode]" show="url, color, size"] but of course it doesn't work.

Answer 1

apparently I found the solution (thanks to amatorpl), if anyone needs it:

function show_history() {

$user = wp_get_current_user();
$user_email = $user->user_email;

$show_history = '[shortcode_name search="'.$user_email.'" show="url, color, size"]';
$history =  do_shortcode($show_history);

return $history;
}

add_shortcode('show_history', 'show_history'); 

Thanks for the try
