Question

Hi I have problem in my DB Query.

$q = $this->db->query("SELECT * FROM (`knihy`) 
                      WHERE `stav` = 1 
                      AND (Autor1 LIKE '$vyraz' 
                      OR Autor2 LIKE '$vyraz' 
                      OR Autor3 LIKE '$vyraz' 
                      OR Autor4 LIKE '$vyraz') 
                      ORDER BY `id` desc LIMIT $limit OFFSET $offset ");

The problem is that, when I am searching for example for “lorem” and I have in my table for example in row Autor1 content: “lorem ipsum” nothing will be found. But if I am searching for lorem ipsum there will be found those one field. Where is problem please?

You’re not using the right syntax for LIKE:

Autor1 LIKE '$vyraz'

Should be:

Autor1 LIKE '%$vyraz%'

Without the wildcards, you’re just doing an exact match.
