我有cms博客codeigniter。但是當我限制文章內容不起作用。我是codeigntier的新手,你能告訴我該怎麼做。如何限制codeigniter中的numwords文章?
這是控制器cms_helper.php
function get_excerpt($article, $numwords = 20){
$string = '';
$url = article_link($article);
$string .= '<h2>' . anchor($url, e($article->judul_berita)) . '</h2>';
$string .= '<p class="pubdate">' . e($article->tanggal) . '</p>';
$string .= '<p>' . e(limit_to_numwords(strip_tags($article->content), $numwords)) . '</p>';// content is not show
$string .= '<p>' . anchor($url, 'Read more', array('judul_berita' => e($article->judul_berita))) . '</p>';
return $string;
}
function limit_to_numwords($string, $numwords){
$excerpt = explode(' ', $string, $numwords + 1);
if (count($excerpt) >= $numwords) {
array_pop($excerpt);
}
$excerpt = implode(' ', $excerpt);
return $excerpt;
}
function e($string){
return htmlentities($string);
}
private function _homepage()
{
$this->load->model('mberita');
$this->db->limit(6);
$this->data['articles'] = $this->mberita->get_berita();
//var_dump($this->data['articles']);
}
請幫我做什麼。謝謝。
