I added multi words(seperate by space) search feature in my installation.
knowledgebase.php

Code: Select all

function hesk_kb_search($query) {
	global $hesk_settings, $hesklang;

    define('HESK_NO_ROBOTS',1);

	/* Print header */
    $hesk_settings['tmp_title'] = $hesklang['sr'] . ': ' . substr(hesk_htmlspecialchars(stripslashes($query)),0,20);
	require_once(HESK_PATH . 'inc/header.inc.php');
	hesk_kb_header($hesk_settings['kb_link']);

	$arr=preg_split('/[\s,]+/',$query); // zhang:seperate with space or comma
	for ($i=0;$i<count($arr);$i++) $arr[$i]='CONCAT(subject,content) LIKE "%'.$arr[$i].'%"'; //zhang:create conditions
	$cond=join(' AND ', $arr);
	$sql = 'SELECT t1.* FROM `'.hesk_dbEscape($hesk_settings['db_pfix']).'kb_articles` AS t1 LEFT JOIN `'.hesk_dbEscape($hesk_settings['db_pfix']).'kb_categories` AS t2 ON t1.`catid` = t2.`id` WHERE t1.`type`=\'0\' AND t2.`type`=\'0\' AND ('.$cond.') ORDER BY subject DESC LIMIT 99';

if type more than 3 english words then press Enter, it work well, but if type more than 3 Chinese words,it show a blank page with the url like this:

http://mylaptop/hesk/knowledgebase.php? ... 9C%9F+dadf

any idea?

Do you get any errors if you enable Debug mode in HESK settings?

And check your server logs, it could be something on the server blocking the request (mod_security?).
