Help with the iframe code

Same domain or different?
Are cookies involved?

Different domains.

User register on my website https://www.mywebsite.com and when a user fire up that iframe it should open that iframe https://www.website.com and automatically register that user in that website or login that user if that user already exist.

Not sure if it will make it easier if we involved cookies.

Sorry I’m just a beginner at this.

Thanks for the quick response too

Easier, no, more secure

In regards to getting your current users information, you would want to get the current logged in user via wp_get_current_user()

not working out for me

out of my league I guess

Trying to put this in a wordpress page but i guess i can’t run php inside a page.

<iframe src=”https://www.gpmonlineshop.com/lobby/lobby.asp?c=customerid&phpu=&#8217; . $current_user->user_login . ‘&phpp=’ . $current_user->$user_pass_md5 . ‘&phpe=’ . $current_user->user_email . ‘” width=”1024″ height=”768″></iframe>

Oh well I guess we just have to settle with double registration

Can you wrap your code in the back ticks please, easier to read

Is that your entire block?
It looks like your in a PHP block mid echo()

If not, you not breaking in and out of PHP, for example

<?php
$current_user = wp_get_current_user();
echo('<iframe src="https://www.gpmonlineshop.com/lobby/lobby.asp?c=customerid&phpu=' . $current_user->user_login . '&phpp=' . $current_user->user_pass_md5 . '&phpe=' . $current_user->user_email . '" width="1024" height="768"></iframe>');
?>

I managed to solved this by using the get_userinfo

‘<?php
/*
Template Name: xxxxxxxx
*/
?>
<?php if ( is_user_logged_in() ) { ?>
<?php global $current_user; get_currentuserinfo(); ?>
<?php } else { ?>
<?php wp_redirect(‘https://xxxxxxxxx.com/&#8217;); ?>
<?php } ?>’
