[SOLVED] Error after PHP 5.6 upgrade, OC 1.5.6.4

Hi!

My host, (Dreamhost) is planning a manditory upgrade to PHP 5.6 soon. Thus far we have been on 5.3. Today I manually set the server to PHP 5.6 for testing, and got the following error at the top of the site:

Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in /home/cmargo5/shop.pacherbs.com/system/database/mysql.php on line 6

Can anyone clue me in on what this is related to, and what I might do to remedy the error?

My system/database/mysql.php file line #6 reads:

if (!$this->link = mysql_connect($hostname, $username, $password)) {

My skills stop here, as I don't really know what I'm looking at.

Thanks in advance for any assistance!

change in BOTH config.php files:
define('DB_DRIVER', 'mysql');
to:
define('DB_DRIVER', 'mysqli');
and check again !

AND DELETE your second Posting, as long as nobody else replies to, it makes very little sense, to double post around here...

Thanks, that worked! I don't see how to delete a post though...

Just edit the title of your original post and put (Solved) at the beginning.

No one wants the post deleted as it might help others.

he/she created two different Posts, on the same matter, But as long as no-one else replies to, one can always later remove such an 'empty' post again. That's what I meant.

Ernie

Sorry Ernie, I didn't even notice you mentioned a 2nd post.

Well, either way, I don't see the delete post link.

I marked both threads as solved, and included the fix in the other thread as well.
