Switch to the directory where the theme is located, open functions.php, and add the following code:
function jackyexcerpt($max_char = 200, $more_text = ‘…’, $limit_type = ‘content’) {
if ($limit_type == ‘title’) { $text = get_the_title(); }
else { $text = get_the_content(); }
$text = apply_filters(‘the_content’, $text);
$text = strip_tags(str_replace(‘]]>’, ‘]]>’, $text));
$text = trim($text);
if (strlen($text) > $max_char) {
$text = substr($text, 0, $max_char+1);
$text = utf8_conver($text);
$text = str_replace(array(“\r”, “\n”), ‘ ‘, $text);
$text .= $more_text;
if ($limit_type == ‘content’){
$text = “<p>”.$text.”</p>”;
$text .= “<div class=’read-more-wrapper’><a href='”.get_permalink().”‘ title=’read more’ rel=’nofollow’><span>Read More</span></a></div>”;
}
echo $text;
} else {
if ($limit_type == ‘content’){$text = “<p>”.$text.”</p>”;}
echo $text;
}
}
function utf8_conver($str) {
$len = strlen($str);
for ($i=strlen($str)-1; $i>=0; $i-=1){
$hex .= ‘ ‘.ord($str[$i]);
$ch = ord($str[$i]);
if (($ch & 128)==0) return(substr($str,0,$i));
if (($ch & 192)==192) return(substr($str,0,$i));
}
return($str.$hex);
}
Just use the following code to call the place where you need to display the summary:
<?php jackyexcerpt(200);?>
