I'm using a live AJAX search for my website.
I downloaded the script from ninetofive.me/data/tutorials/live-search/
.
When I search, I get Fatal error: Call to a member function fetch_array() on a non-object in E:\xampp\htdocs\test\ajaxsearch\search.php on line 54
.
I didn't make any changes in the demo script other than changing the MySQL credentials.
Here is my search.php:
<?php
// Credentials
$dbhost = "localhost";
$dbname = "testdb";
$dbuser = "root";
$dbpass = "";
// Connection
global $tutorial_db;
$tutorial_db = new mysqli();
$tutorial_db->connect($dbhost, $dbuser, $dbpass, $dbname);
$tutorial_db->set_charset("utf8");
// Check Connection
if ($tutorial_db->connect_errno) {
printf("Connect failed: %s
", $tutorial_db->connect_error);
exit();
}
