Question

I’m coding a website to learn more about PHP and am making a JQuery Autosuggest. The scripts here.

Here’s my code for the autosuggest.php:

<?php
 $db = new mysqli('localhost', 'root' ,'***********', '**********');

if(!$db) {

    echo 'Could not connect to the database.';
} else {

    if(isset($_POST['queryString'])) {
        $queryString = $db->real_escape_string($_POST['queryString']);

        if(strlen($queryString) >0) {

            $query = $db->query("SELECT * FROM company WHERE name LIKE '$queryString%' LIMIT 10");
            if($query) {
            echo '<ul>';
                while ($result = $query ->fetch_object()) {
                    echo '<li onClick="fill(\''.addslashes($result->name).'\');">'.$result->name.'</li>';
                }
            echo '</ul>';

            } else {
                echo 'OOPS we had a problem :(';
            }
        } else {
            // do nothing
        }
    } else {
        echo 'There should be no direct access to this script!';
    }
}
?>

Now, instead of just searching for the name in the company table, I’d like to search for the cat field in a different table (called cat) and the subcat field in a different table than that ( in a table called subcat)

My table structure:

So I want to search from three tables. Is this possible and how can I do it with my code?

Thanks for all help!

Answer 1

You should do a UNION between each of the 3 tables and normalize the data into Name, ID and Type columns.
