Advanced Excerpt

Current sites using this plugin: (every site, part of GlmTheme)

Example of PHP call to plugin function

<?php echo (function_exists('the_advanced_excerpt')) ? the_advanced_excerpt('length=250&length_type=characters&no_custom=1&ellipsis=%26hellip;&exclude_tags=a,img,p,div,h1,h2,h3,h4,h5,h6'): the_excerpt(); ?>

To have advanced excerpt only add an "Add More" button when the excerpt text exceeds the maximum allowed excerpt size as set in the Admin side (or through the function above).

function ca_only_add_more_when_required( $default, $text, $options ) {
    $text = strip_tags( $text );
    if ( 'words' === $options['length_type'] ) {
        $excerpt_length = str_word_count( $text );
    } else {
        $excerpt_length = strlen( $text );
    }
    if ( $excerpt_length > $options['length'] ) return $default;
    return true;
}
add_filter( 'advanced_excerpt_disable_add_more', 'ca_only_add_more_when_required', 10, 3 );
