Formating Tags escaping from the schedule page

1) Don’t forget to take a back up of the file prior to any changes.

2) Please install and activate Vertoh child theme. Otherwise you will lose the changed files when you upgrade the theme. Please have a look on this tutorial below:

https://showthemes.zendesk.com/docs/vertoh/documentation-and-theme-guide/#3.4

3) Open functions.php from the vertoh-child theme, and add the following script at the end of the page.

function wpse_allowedtags() {
// Add custom tags to this string
return ‘<script>,<style>,<br>,<strong><em>,<i>,<ul>,<ol>,<li>,<a>,<p>,<img>,<video>,<audio>,<pre>,&nbsp;’;
}

if ( ! function_exists( ‘wpse_custom_wp_trim_excerpt’ ) ) :

function wpse_custom_wp_trim_excerpt($wpse_excerpt) {
$raw_excerpt = $wpse_excerpt;
if ( ” == $wpse_excerpt ) {

$wpse_excerpt = get_the_content(”);
$wpse_excerpt = strip_shortcodes( $wpse_excerpt );
$wpse_excerpt = apply_filters(‘the_content’, $wpse_excerpt);
$wpse_excerpt = str_replace(‘]]>’, ‘]]&gt;’, $wpse_excerpt);
$wpse_excerpt = strip_tags($wpse_excerpt, wpse_allowedtags()); /*IF you need to allow just certain tags. Delete if all tags are allowed */

//Set the excerpt word count and only break after sentence is complete.
$excerpt_word_count = 75;
$excerpt_length = apply_filters(‘excerpt_length’, $excerpt_word_count);
$tokens = array();
$excerptOutput = ”;
$count = 0;

// Divide the string into tokens; HTML tags, or words, followed by any whitespace
preg_match_all(‘/(<[^>]+>|[^<>s]+)s*/u’, $wpse_excerpt, $tokens);

foreach ($tokens[0] as $token) {

if ($count >= $excerpt_length && preg_match(‘/[,;?.!]s*$/uS’, $token)) {
// Limit reached, continue until , ; ? . or ! occur at the end
$excerptOutput .= trim($token);
break;
}

// Add words to complete sentence
$count++;

// Append what’s left of the token
$excerptOutput .= $token;
}

$wpse_excerpt = trim(force_balance_tags($excerptOutput));

$excerpt_end = ‘ <a href=”‘. esc_url( get_permalink() ) . ‘”>’ . ‘&nbsp;&raquo;&nbsp;’ . sprintf(__( ‘Read more about: %s &nbsp;&raquo;’, ‘wpse’ ), get_the_title()) . ‘</a>’;
$excerpt_more = apply_filters(‘excerpt_more’, ‘ ‘ . $excerpt_end);

//$pos = strrpos($wpse_excerpt, ‘</’);
//if ($pos !== false)
// Inside last HTML tag
//$wpse_excerpt = substr_replace($wpse_excerpt, $excerpt_end, $pos, 0); /* Add read more next to last word */
//else
// After the content
$wpse_excerpt .= $excerpt_more; /*Add read more in new paragraph */

return $wpse_excerpt;

}
return apply_filters(‘wpse_custom_wp_trim_excerpt’, $wpse_excerpt, $raw_excerpt);
}

endif;

remove_filter(‘get_the_excerpt’, ‘wp_trim_excerpt’);
add_filter(‘get_the_excerpt’, ‘wpse_custom_wp_trim_excerpt’);

4) Update the file.
