Hi, i am trying to build a web site but i have problems with the search thing. I didn't do it but i can't get it to work
everytime I try to search something nothing'sshowing up :(
I tried a lot,help plz :noh:

here is my html

Code:
<form id="search" action="search.php" method="GET" accept-charset="utf-8" >
   <div class="clearfix">
     <input type="text" name="s" onBlur="if(this.value=='') this.value=''" onFocus="if(this.value =='' ) this.value=''" >
     <a href="#" onClick="document.getElementById('search').submit()" class="btn btn-1">Search</a> 
   </div>
 </form>

Here is a part of my search.php

Code:
<script type="text/javascript" src="search/search.js"></script>
 
 <div class="span12">
   <h3>Search result:</h3>
   <div id="search-results"></div>
 </div>

Here is my search.js

Code:
$(function(){
 var s=location.search.replace(/^\?.*s=([^&]+)/,'$1')
 ,form=$('#search-form')
 ,input=$('input[type=text]',form)
 ,results=$('#search-results').height(0)
 ,src='search/results.php'
 ,ifr=$('<iframe width="100%" height="100%" frameborder="0" marginheight="0" marginwidth="0" allowTransparency="true"></iframe>')
 
 if(results.length)
 ifr
 .attr({
 src:src+'?s='+s
 })
 .appendTo(results)
 ,input
 .val(decodeURI(s))
 
 window._resize=function(h){
 results
 .height(h)
 }
 })

And finaly my result.php

Code:
<?php
 
 if(!isset($_GET['s'])) {
 die('You must define a search term!');
 }
 
 $highlight = true;//highlight results or not
 $search_in = array('html', 'htm');//allowable filetypes to search in
 $search_dir = '../';//starting directory
 $recursive = true;//should it search recursively or not
 define('SIDE_CHARS', 80);
 $file_count = 0;
 $search_term = mb_strtolower($_GET['s'], 'UTF-8');
 //$search_term = $_GET['s'];
 $search_term_length = strlen($search_term);
 $final_result = array();
 
 $files = list_files($search_dir);
 
 foreach($files as $file){
 $contents = file_get_contents($file);
 preg_match("/\<title\>(.*)\<\/title\>/", $contents, $page_title); //getting page title
 if (preg_match("#\<body.*\>(.*)\<\/body\>#si", $contents, $body_content)){ //getting content only between <body></body> tags
 $clean_content = strip_tags($body_content[0]); //remove html tags
 $clean_content = preg_replace( '/\s+/', ' ', $clean_content ); //remove duplicate whitespaces, carriage returns, tabs, etc
 
 //$found = strpos_recursive($clean_content, $search_term);
 $found = strpos_recursive(mb_strtolower($clean_content, 'UTF-8'), $search_term);
 $final_result[$file_count]['page_title'][] = $page_title[1];
 $final_result[$file_count]['file_name'][] = $file;
 }
 if($found && !empty($found)) {
 for ($z = 0; $z < count($found[0]); $z++){
 $pos = $found[0][$z][1];
 $side_chars = SIDE_CHARS;
 if ($pos < SIDE_CHARS){
 $side_chars = $pos;
 $pos_end = SIDE_CHARS + $search_term_length;
 }else{
 $pos_end = SIDE_CHARS*2 + $search_term_length;
 }
 
 $pos_start = $pos - $side_chars;
 $str = substr($clean_content, $pos_start, $pos_end);
 $result = preg_replace('#'.$search_term.'#ui', '<span class="search">\0</span>', $str);
 //$result = preg_replace('#'.$search_term.'#ui', '<span class="search">'.$search_term.'</span>', $str);
 $final_result[$file_count]['search_result'][] = $result;
 }
 } else {
 $final_result[$file_count]['search_result'][] = '';
 }
 $file_count++;
 }
