Modifications to Post Slider

Hi there,

Loving the flexibility of your theme and the fantastic support you offer.

I’m trying to “trick out” the Post Slider on my website and am hitting some obstacles. Please see below and let me know what is possible.

Notes
I am currently using the following function to randomize the post order. This code is working great. I wanted to let you know, in case this code interferes with anything else.

add_filter('avia_post_slide_query', 'enfold_customization_query_custom');
function enfold_customization_query_custom( $query ) {
	$query['orderby'] = 'rand';
	return $query;
}

Customization 1: Fixing excerpt length

Fixing the excerpt length will allow the blog posts to display uniformly. The code below was on a previous support topic. I’ve attempted modifying the “return value” to no effect. Can you assist in me making the excerpt length a certain amount?

// POST SLIDER EXCERPT LENGTH
add_filter('avf_postgrid_excerpt_length','avia_change_excerpt_length',10,1);
function avia_change_excerpt_length()
{
return 30;

}

Customization 2: Changing “Read More” text

I’ve modified the Read More link in includes/loop-index.php, but the text on the “Read More” link remains the same. Here’s the code I’ve modified in loop-index.php:

	$current_post['content'] = apply_filters( 'avf_the_content', '', 'loop_index' );
	if( '' == $current_post['content'] )
	{
		$current_post['content'] 	= $blog_content == "content" ? get_the_content(__('Read »','avia_framework').'<span class="more-link-arrow"></span>') : get_the_excerpt();

Please advise on how to modify the “Read More” text correctly.

Customization 3: Change symbol on slider controls

How would I replace the symbol on the slider controls from the simple “>” or “<” to a character or image of my choosing?

You guys rock! Thanks in advance for all of your help.
