PHP - Search Bar Results

Hello,

I'm developing a website that asks the user to submit a keyword for a search. The results should display matches for this keyword, but also show matches for related keywords (in order of relevenace!).

I'm planning on building up a library of which search terms users use in the same sessions (e.g. if someone searches for "it jobs" and "php jobs", I'll know the terms are correlated), and I'll also measure the click-through rates of the items on the results list.

I've been spending all weekend trying to map out the design for this but it's proving incredibly complicated and I think the solution is likely to be on the internet somewhere already?!

Please could someone point me in the right direction if you've come accross this problem before?

Thanks a million,

Stu

I am trying to write a script that will allow me visitors to my site to search my database for items. I followed a tutorial that I had found and tweaked it to fit my needs. I am not getting any results it keeps telling that there was no search results found. Even though I have the items that I have been testing on in my database.

I have two files the main search.php file and the search_func.php file

Here is the search.php file
Code: [Select]
<form method='post' action='search.php'>
<fieldset>
<input type='text' name='search' id='search' value='type name here'/>
<input type='submit' name='search_submit' id='search_submit' value='search'/>
</fieldset>
</form>

<?php

include('includes/search_func.php');

if(isset($_POST['search'])) {
$keywords = mysql_real_escape_string(htmlentities(trim($_POST['search'])));

$errors = array ();

if (empty($keywords )){
$errors[] = 'Please enter a search term';
} else if (strlen($keywords ) < 3 ) {
$errors[] = 'Search term must be more then three characters long';
} else if (search_results($keywords  == false)) {
$errors[] = 'Your search for ' .$keywords . ' showed no results';
}

if (empty($errors)) {
$results = search_results($keywords );
$results_num = count($results);
$suffix = ($results_num != 1) ? 's' : '';
echo 'Your search for <strong>'. $keywords  .'</strong> returned <strong>' .$results_num.'</strong> result'.$suffix.'';

foreach($results as $result) {
echo $result['first'];
}

} else {
foreach($errors as $error){
echo $error;
}
}

}

?>
Here is the search_func.php file
Code: [Select]
<?php
include('includes/config.php');
connect();

function search_results($keywords ) {
$returned = array();
$where = "";

$keywords  = preg_split('/[\s+]/', $keywords );
$total = count($keywords );

foreach($keywords  as $key=>$keyword) {
$where .= "`l_name` LIKE '%$keyword%'";

if($key != ($total - 1)){
$where .= "OR";
}
}

$results  = "SELECT `l_name`,`f_name`,`image`,`item_return` FROM `ttmautos` WHERE $where";
$results_num = ($results = mysql_query($results)) ? mysql_num_rows($results): 0 ;

if ($results_num === 0) {
return false;
} else {
while($results_row = mysql_fetch_assoc($results)) {
$returned_results[] = array(
'last' => $results_row['l_name'],
'first' => $results_row['f_name'],
'image' => $results_row['image'],
'item' => $results_row['item_return']
);
}

return $returned_results;
}
}
?>

If anyone could give me an idea of what I am doing wrong I would appreciate it.

What I expect:
- The function to loop output all of the rows which match the search results.

The problems:
- Only 1 row is matched.
- Notice: Undefined index: id in G:\xampp\htdocs\xampp\dsa\search_func.php on line 57
- The image is not showing

Line 57:
Code: [Select]
$id = $_REQUEST['id'];

Hi,
I have a problem if users search something which doesn't match the data in the table I'm selecting from.

At the moment I'm trying this code:
Code: [Select]
<?php 
require_once('inc/global.inc.php');

# search.inc.php

/* 
 * This is the search content module.
 * This page is included by index.php.
 * This page expects to receive $_GET['terms'].
 */

// Redirect if this page was accessed directly:
if (!defined('BASE_URL')) {

// Need the BASE_URL, defined in the config file:
require_once ('../includes/config.inc.php');

// Redirect to the index page:
$url = BASE_URL . 'index.php?p=search';

// Pass along search terms?
if (isset($_GET['terms'])) {
$url .= '&terms=' . urlencode($_GET['terms']);
}

header ("Location: $url");
exit;

} // End of defined() IF.

// Print a caption:
echo '<h2>Search Results</h2>';

// Display the search results if the form
// has been submitted.
if (isset($_GET['terms']) && ($_GET['terms'] != 'Search...') ) {

$terms = $_GET['terms'];
$dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME) or die *('Error connecting to MySQL server');
// Query the database.
$query = "SELECT * FROM product WHERE title LIKE '%$terms%'";

// Fetch the results.
//$row = mysqli_fetch_array($result);

// Print the results:

$result=mysqli_query($dbc,$query);

if ($result == 0){
  echo "<h3>Sorry,</h3>";
  echo "<p>your search: &quot;" .$terms. "&quot; returned zero results</p>";
}

while($row=mysqli_fetch_assoc($result)) {

$output[] = '<ul>';
$output[] = '<li>'.$row['title'] .': &pound;'.$row['price'].'<br /><img src="'.$row['img'].'" alt="'.$row['title'].'" /></li>';
$output[] = '</ul>';
}
echo join('',$output);
}

else { // Tell them to use the search form.
echo '<p class="error">Please use the search form at the top of the window to search this site.</p>';
}



?>

But I'm getting this error:
Object of class mysqli_result could not be converted to int

So that little if statement here doesn't work:
Code: [Select]
if ($result == 0){
  echo "<h3>Sorry,</h3>";
  echo "<p>your search: &quot;" .$terms. "&quot; returned zero results</p>";
}

Is there another way I can display no search matched results?

Thank you for reading,
Andrew.

I have a page that I am using to search a database. Basically what I want to do is allow the end user to sort by column headings after the search results are returned. The sort code that I am using works fine on a "lesser complicated" page that does not involve $_GET variables. I am not sure however if I adapted it properly. Also, I am having problems adding the new $_GET variables to the URL string when the user chooses to sort the returned search results. Thank you in advance for any suggestions. My code is below:

Code: [Select]
