Question

I want to write a php code that can search for multiple keywords separated by a column. Currently my code is working accurately for a particular single keyword.
Also; what changes should i make in the SQL table?

<?php
include('db.php');
if($_POST)
{
$q=$_POST['searchword'];
$sql_res = mysql_query("SELECT tag_id, tag_name FROM ttl_tags WHERE tag_name like '%$q%' ORDER BY tag_id LIMIT 5");
while($row=mysql_fetch_array($sql_res))
{
$tagid=$row['tag_id'];
$tagname=$row['tag_name'];
$re_tagname='<b>'.$q.'</b>';
$final_tagname = str_ireplace($q, $re_tagname, $tagname);

?>

Answer 1

If I am reading your question right, you want to search for multiple keywords in a single column? If so you can do:

 $sql_res = mysql_query("SELECT tag_id, tag_name FROM ttl_tags 
            WHERE tag_name like '%$q%' OR tag_name like 'ANOTHER_PARAMETER'  
            ORDER BY tag_id LIMIT 5"); 

You can put as many “OR”s that you want.
