PHP search script for multiple words

[Mo sdn]

Hey,

I have the following issue:

I can't search multiple words.

I have a search engine who search just the full string:

PHP Code:

***

<?php

function ft_search_info() {
return array(
'name' => 'Search: Search files and folders.',
);
}
function ft_search_sidebar() {
$sidebar[] = array(
"id" => "search_1",
"content" => '<div class="section">
<h2>'.t('Search files &amp; folders').'</h2>
<form action="" method="post" id="searchform">
<div>
<input type="text" name="q" id="q" size="16" value="'.$_REQUEST['q'].'" />
<input type="button" id="dosearch" value="'.t('Search').'" />
</div>
<div id="searchoptions">
<input type="checkbox" name="type" id="type" checked="checked" /> <label for="type">'.t('Search only this folder and below').'</label>
</div>
<div id="searchresults"></div>
</form>
</div>'
);
return $sidebar;
}
function ft_search_ajax($act) {
if ($act = '%search%') {
$new = array();
$ret = "";
$q = $_POST['q'];
$type = $_POST['type'];
if (!empty($q)) {
if ($type == "true") {
$list = _ft_search_find_files(ft_get_dir(), $q);
} else {
$list = _ft_search_find_files(ft_get_root(), $q);
}
if (is_array($list)){
if (count($list) > 0) {
foreach ($list as $c) {
if (empty($c['dir'])) {
$c['dirlink'] = "/";
} else {
$c['dirlink'] = $c['dir'];
}
if ($c['type'] == "file") {
$link = "<a href='".ft_get_root()."{$c['dir']}/{$c['name']}' title='" .t('Show !file', array('!file' => $c['name'])). "'>{$c['shortname']}</a>";
if (HIDEFILEPATHS == TRUE) {
$link = ft_make_link($c['shortname'], 'method=getfile&amp;dir='.rawurlencode($c['dir']).'&amp;file='.$c['name'], t('Show !file', array('!file' => $c['name'])));
}
$ret .= "<dt>{$link}</dt><dd>".ft_make_link($c['dirlink'], "dir=".rawurlencode($c['dir'])."&amp;highlight=".rawurlencode($c['name'])."&amp;q=".rawurlencode($q), t("Highlight file in directory"))."</dd>";
} else {
$ret .= "<dt class='dir'>".ft_make_link($c['shortname'], "dir=".rawurlencode("{$c['dir']}/{$c['name']}")."&amp;q={$q}", t("Show files in !folder", array('!folder' => $c['name'])))."</dt><dd>".ft_make_link($c['dirlink'], "dir=".rawurlencode($c['dir'])."&amp;highlight=".rawurlencode($c['name'])."&amp;q=".rawurlencode($q), t("Highlight file in directory"))."</dd>";
}
}
return $ret;
} else {
return "<dt class='error'>".t('No files found').".</dt>";
}
} else {
return "<dt class='error'>".t('Error.')."</dt>";
}
} else {
return "<dt class='error'>".t('Enter a search string.')."</dt>";
}
}
}
function ft_search_add_js_call() {
$return = '';
$return .= "$('#searchform').ft_search({\r\n";
if (!empty($_REQUEST['dir'])) {
$return .= "\tdirectory: '{$_REQUEST['dir']}',\r\n";
} else {
$return .= "\tdirectory: '',\r\n";
}
$return .= "\tformpost: '".ft_get_self()."',\r\n";
$return .= "\theader: '".t('Results')."',\r\n";
$return .= "\tloading: '".t('Fetching results&hellip;')."'\r\n";
$return .= '});';
return $return;
}
function _ft_search_find_files($dir, $q){
$output = array();
if (ft_check_dir($dir) && $dirlink = @opendir($dir)) {
while(($file = readdir($dirlink)) !== false){
if($file != "." && $file != ".." && ((ft_check_file($file) && ft_check_filetype($file)) || (is_dir($dir."/".$file) && ft_check_dir($file)))){
$path = $dir.'/'.$file;

if(stristr($file, $q)) {
$new['name'] = $file;
$new['shortname'] = ft_get_nice_filename($file, 20);
$new['dir'] = substr($dir, strlen(ft_get_root()));
if (is_dir($path)) {
if (ft_check_dir($path)) {
$new['type'] = "dir";
$output[] = $new;
}
} else {
$new['type'] = "file";
$output[] = $new;
}
}

if(is_dir($path)) {
$dirres = _ft_search_find_files($path, $q);
if (is_array($dirres) && count($dirres) > 0) {
$output = array_merge($dirres, $output);
unset($dirres);
}
}
}
}
sort($output);
closedir($dirlink);
return $output;
} else {
return FALSE;
}
}

Can someone help me?

I haven't gone through all the code but here is my suggestion.

Try using explode() function of PHP and you will get each word into the array node.

Example
$resultmain = "";
$search = "Hello This Is Test";
$parts =explode(" ", $search);
foreach($parts as $key => $value)
{
$result = //Search for $value from here and get the results.
$resultmain = $resultmain + $result;
}


Then you can loop through each node of that array and just do the simple straight forward search and append the results to the main resultset.

Thanks.

Is your current script pretty much just reading a directory and parsing the filenames?

What type of files are you trying to search in? This matters a lot as different things will need different approaches, it's not really a 1 fit all solution.

I found your post on phpfreaks, http://forums.phpfreaks.com/topic/288278-search-text-in-a-word-document-with-php/ which seems to point to it being word documents.

You'd need to use something like this,

http://stackoverflow.com/questions/...ct-text-from-word-file-doc-docx-xlsx-pptx-php

to convert the file to text files then you would be able to just read the files using php as normal.

Which could be done like this
