How to solve the unwanted "continue reading" link problem

Hi Micah,

First of all, fantastic work on this plugin. I just wanted to share my solution to the “Continue Reading” link issue in-plugin.

One of the other solutions offered was to “hide” the link in CSS, however this may mean an SEO hit due to masked links, so I wanted to provide a plugin-controlled way to remove the link altogether.

This is really to help people that don’t feel comfortable messing with code and function files etc (and because no matter how I tried to disable it myself in functions, no combination of overrides or action weights helped the issue (using a child theme derived from twentyeleven).

PLEASE NOTE: This solution will break if the plugin is updated… maybe this can be added to the next version?

My solution was to add a line into promotion-slider/includes/functions.php:

function promoslider_display_excerpt($values){
	global $post; extract($values);
	$excerpt = preg_replace('/(<a .+?)+(<\/a>)/i', '', $excerpt);
...
...

Notice the addition of the preg_replace line to match the anchor tag, and remove it.

In a user friendly version of this, it would need to be wrapped into an admin option similar to $display_excerpt, where the user could elect to remove the “Continue Reading” link. Something like this in the function:

if($continue_reading == "hide") {
	$excerpt = preg_replace('/(<a .+?)+(<\/a>)/i', '', $excerpt);

Hope this helps!
