Question

I have the following code:

$dbLink = mysql_connect('localhost', 'tester', 'test');
mysql_select_db('acianetm_pcSpec', $dbLink);
$q = $_GET['q'];
$q = mysql_real_escape_string($q);
$sql = "
    SELECT *,
        MATCH(part) AGAINST ('$q') AS score
    FROM parts
    WHERE MATCH(part) AGAINST('$q')
"; 
$rest = MySQL_query($sql); 
while($row = MySQL_fetch_array($rest)) { 
echo "<br /> <strong>".$row['id']. " - ". $row['part']. " - $". $row['price']."</strong>"; 
}

When I load up http://site.com/q?=Nvidia it does not display any output.

MySQL Structure:

CREATE TABLE `parts` (
`id` int(10) NOT NULL auto_increment,
`part` varchar(512) NOT NULL,
`price` varchar(15) NOT NULL,
`updated` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
PRIMARY KEY  (`id`),
UNIQUE KEY `part_2` (`part`),
FULLTEXT KEY `part` (`part`)
) ENGINE=MyISAM AUTO_INCREMENT=47 DEFAULT CHARSET=latin1

The data inside the table:
`id |#| part |#| price
46 |#| (VIC Clayton Clearance) GIGABYTE 9800GT 512MB Nvidia Geforce GF9800GT DVI P... |#| 95.00

I have tried this SQL query:
SELECT * FROM parts WHERE part LIKE '%$q%'

However without using str_replace eg. str_replace(' ', '&'. $q); it never worked for multiple words. Using the str_replace only made it work with 2 words, I need multiple.

Doing this in PHPMyAdmin returns no rows either, so what part of the query is wrong?

If someone could assist that would be great.

Thanks alot

Answer 1

Omit the where clause in your sql statement.

Also the '?' in your URL should come before any name value pairs.

Answer 2

$sql = "SELECT * FROM parts
WHERE MATCH(part) AGAINST ('$q')";

Works well :-)
