Purging notifications and PMs from the database: How

I need to clean out all the old user PMs and notification messages. They currently make up about 60% of my database and I need to reduce it to a more manageable size.

I have experimented with deleting the contents of two tables on a test site: priv_msgs and xoopsnotifications. It seems to work.

I am wondering if anyone else has tried this? Will this cause any unexpected problems?

Thanks

at least about pm i do it without any problem for 2 years.
i use a very simple script:
<?php
define("user", "dbuser");
define("pass", "dbpass");
define("host", "localhost");
define("db", "dbname");


$cxn = mysql_connect(host ,user, pass);
mysql_select_db(db);

$delete_time = time() - ( 30 * 24 * 60 * 60 );  // 30 days/month * 24 hrs/day
// * 60 minutes/hour * 60 seconds/min.

$sql = "DELETE from `xoops_priv_msgs` WHERE `read_msg` = '0' AND `msg_time` < '$delete_time'";
//This script would delete everything older than 30 days that has been not read.

$result = mysql_query($sql, $cxn);
?>

and run it every day with a cron.

MP manager can purge pm too but i dont use it because i need to do it automatically every day.

and about notification its in the Herve todo list for the future version of his new module xoopscare.

Just took another look at my database - it turns out that PM's make up 83% of the total database size.

Purging them will reduce my database size from 88.4MB to just 14.5 and make backup considerably easier.

just be careful using this script inside wwwroot because of db informations.
i upload it outside wwwroot and run it with a cron

Just to follow up on this: It works. 92,000 PMs deleted! Database is now a much more manageable size.

Thanks for this irmtfan,

Just tested this on my site, worked perfectly after I changed to my custom prefix.

Now will try to clean up a site with over 5 million PMs. Thansk again.

I am interested as well. I'd also like to know if we can use it in the XOOPS Care module by adding the script to the "Execute Php code" area.

For the following, I assume we add our own information?
define("user", "dbuser");
define("pass", "dbpass");
define("host", "localhost");
define("db", "dbname");

Would it be "dbuser", "dbpass", "localhost", "dbname" that needs modifying? Other than that, anything else?

Thanks...

If you have cpanel on your hosting account, look for a section called 'cron jobs', you can probably run it from there. I am pretty sure you could run it with xoopscare, but haven't tried yet.

Otherwise, you can achieve the same thing manually by deleting the contents of the relevant tables, as noted above. But please don't mess around with your database until you have made a backup!
