Different ID in every shortcode

Question

I am trying to make an Instagram-box on the author profile of my page. I need every profile to be different, and to do that I need to change the ID in my Instagram Widget-shortcode on every page. The shortcode for the widget is:

[instagram-feed id="" imageres="full" showheader="true" showbutton="true" buttoncolor="#fff" buttontextcolor="#000" showfollow="false"]

To change the id on every page I have used the_author_meta('instagram');. The idea was to do this:

echo do shortcode( '[instagram-feed id="<?php the_author_meta('user_email') ?>" imageres="full"  showheader="true" showbutton="true" buttoncolor="#fff" buttontextcolor="#000" showfollow="false"]');

But it wont generate because it's PHP inside a shortcode. I have also tried this:

    echo ( '[instagram-feed id="' ); 
    the_author_meta('instagram');
    echo ( '" imageres="full" showheader="true" showbutton="true" buttoncolor="#fff" buttontextcolor="#000" showfollow="false"]' ); 

which generated the code correctly with a different ID on every profile:

[instagram-feed id="1427468000 (and something different on other profile)" imageres="full" showheader="true" showbutton="true" buttoncolor="#fff" buttontextcolor="#000" showfollow="false"]

But now it will now only display as text, not be the result of the code. Anyone know how I can make this work?

Answer 1

What if you concatenate the string, like

$author_ig = '[instagram-feed id="' . get_the_author_meta('instagram') . '"  imageres="full" showheader="true" showbutton="true" buttoncolor="#fff" buttontextcolor="#000" showfollow="false"]';    
echo do_shortcode($author_ig); 

I used get_the_author_meta instead of the_author_meta, because the former returns the meta as a string while the latter echo's the meta.
