Topic: [HACK] Search results with highlighting and excerpts
Name: highlighted search results
Author: FI-DD
CuteNews Compatibility: 1.3.6 - * (no incompatibility reported yet)
Description: It's an improved way to show the search results.
The search term will be highlighted and shown in an excerpt of the news.
It is template driven and you will have additional quick tags, for example result's title, result's author, result's category.
Demo: http://democute.de.funpic.de/cute/example2.php
Type "cutenews" in the textbox and press "Enter" to see the results.
Instructions:
(All lines refer to an unchanged cutenews 1.3.6 version of each file.)
Part 1: search.php
1. Find (this line 8):
require_once("$cutepath/inc/functions.inc.php");
and add below:

foreach($cat_lines as $single_line){
$cat_arr = explode("|", $single_line);
$cat[$cat_arr[0]] = $cat_arr[1];
$cat_icon[$cat_arr[0]]=$cat_arr[2];
}
2. Find this (line 233):
////////// Showing Result
echo"
[b][url=]$item_arr[2][/url][/b] (". date("d F, Y", $item_arr[0]) .")";
////////// End Showing Result
and replace with this:
////////// Showing Result
include"$cutepath/data/search.tpl";
echo"$search_found";
$search_results = str_replace("{result-title}",$item_arr[2],$search_results);
$search_results = str_replace("{result-author}",$item_arr[1],$search_results);
$search_results = str_replace("{result-cat-id}",$item_arr[6],$search_results);
$search_results = str_replace("{result-category}",$cat[$item_arr[6]],$search_results);
$search_results = str_replace("{result-comments}",countComments($item_arr[0],$archive), $search_results);
if(!empty($item_arr[4])){$item_arr[4] = replace_news("show",$item_arr[4]);
$search_results = str_replace("{result-text}",str_replace("\n",'
',formattext($story,$item_arr[4])),$search_results);
}
else{$item_arr[3] = replace_news("show",$item_arr[3]);
$search_results = str_replace("{result-text}",str_replace("\n",'
',formattext($story,$item_arr[3])),$search_results);
}
$search_results = str_replace("[result-link]", "[url=]",$search_results); //You may add &$user_query here.
$search_results = str_replace("[/result-link]","[/url]", $search_results);
echo"$search_results";
////////// End Showing Result

Add this at the end of the file before the last ?>
////////////////////////////////////////////////////////
// Function: formattext
function formattext($whatfind, $html)
{
$text = strip_tags($html);
$pos = @strpos(strtoupper($text),strtoupper($whatfind));
$otstup = 200; //set the number of letters to display for each result
$result = '';
if ($pos !== false)
{

{
