Complex do_shortcode statements

Hi there,

I am trying to construct a do_shortcode statement in a PHP code widget, using a custom field. The idea is to get a shortcode evaluated inside a widget.

The shortcode I’m trying to create is (this is an example)

[flickrgallery setid=”72157626892022672″]

I want to use a custom value (called per_post_widget_content) on a per-post basis that lets me enter 72157626892022672 in a field.

I figure I have to have statements that echo ‘[flickrgallery setid=”‘, then get_post_meta for the custom field value (this part works), then echo ‘”]’

The do_shortcode statement I have so far is

<?php global $post do_shortcode(echo ‘[flickrgallery setid=”‘; echo get_post_meta($post->ID, ‘per_post_widget_content’, true); echo ‘”]’;); ?>

This does not work.

I’ve tried variations on this, but I can’t get the syntax right – can someone give me a pointer on what I’m doing wrong?
