   Ah...more learning time! Does anyone have a coding method to add php variable to the end of the "more-link" style in the WordPress core by adding it to the functions.php file? Basically letting a person choose from theme settings their choice of a Read More button which would add their choice to the end of the more-link. Example, you choose blue in theme settings, this will add to the existing class="more-link-blue" in the page.

   I'd rather do this direct with the "actual" more-link from the functions.php than to add a another style to the more link there.

   Is this possible? Thanks in Advanced!

   Add as many classes as you need into the array... :)
   

   $var_declared_outside_function = 'something';
   
   add_filter( 'the_content_more_link', 'add_morelink_classes' );
   function add_morelink_classes( $more_link_html ) {
   	// Example - else this var has no scope inside the function
   	global $var_declared_outside_function;
   
   	$new_classes = array( 'newclass1', 'newclass2' );
   	$more_link_html = str_replace( 'class="more-link', 'class="' . implode( ' ', $new_classes ) . ' more-link', $more_link_html );
   
   	return $more_link_html;
   }

   If you're pulling classes from your own variable that's declared outside the function remember to globalise the var..
   

   global $your_var_with_data;

   Hope that helps.. ;)

   Thanks Mark, I will give this a try (as I'm still a beginner in php and wordpress methods). For the global var... where would I be placing that line?
