I got this fatal eror message on my WP dashboard:
Plugin could not be activated because it triggered a fatal error.
Parse error: syntax error, unexpected '.', expecting ',' or ';' in /home/fabergla/public_html/markcorbettwilson.com/wp/wp-content/plugins/creativecommons-wordpress-plugin-2.1-beta/includes/class-creativecommons-button.php on line 9

@simonemontrucchio This is likely to be due to the fact that you are running an outdated PHP version (< 5.4). The problem lies in the compact syntax for defining an array:

foreach (['license_url', 'attribution_url', 'source_work_url', 'extra_permissions_url'] as $field) {

which instead could be

foreach ( array( 'license_url', 'attribution_url', 'source_work_url', 'extra_permissions_url' ) as $field) {

As explained here :)
However, I don't see any reason why we should be using a syntax that is not backwards-compatible, since there is another that is. I have just submitted PR #56 fixing the issue :)

from wp-plugin-creativecommons.

May I suggest to define the array outside of the loop?

This is:

1. more readable
2. better performance (although I doubt you'll notice) due to the array being defined each foreach call.

Instead of:
foreach ( array( 'license_url', 'attribution_url', 'source_work_url', 'extra_permissions_url' ) as $field) {

I'd suggest:

$license_metadata = array( 'license_url', 'attribution_url', 'source_work_url', 'extra_permissions_url' );
foreach( $license_metadata as $field) {

Totally! Just done that :)
