My question is what can I do if someone searches for php script for search?
I would want to use OR in my SQL statment. The problem is how do I write the
query so that it will detect the number of words sent then put enough ORs
and LIKE '%$search[1]% in?
Thanks.
Here is the script.
<?
include "includes/required.php";
$query = "
SELECT count(article_keyword.weight) as score, article_keyword.aid,
article_data.name, article_data.time, article_data.description
FROM article_keyword,article_data
WHERE article_keyword.aid = article_keyword.aid AND article_keyword.keyword
LIKE '%$search%'
GROUP BY article_keyword.aid
ORDER BY score DESC
";
$result = mysql_query($query) or die("Query failed: $query<br>" .
mysql_error());
$num_results = mysql_num_rows($result);
if($num_results == 0){
echo "Your search returned no results. Try other keyword(s).";
exit;
} elseif($num_results > 0){
for ($i=0; $i < $num_results; $i++)
{
$row = mysql_fetch_array($result);
echo '<tr><td>';
do_hr();
echo '<a href="full_article.php?aid='.$row['aid'].'">';
do_h($row['name'].' - '.date('jS-M-Y',$row['time']), 3, 'n');
echo '</a>';
echo '</td></tr><tr><td>'.$row['description']."\n";
echo '</td></tr>';
}
}
?>
