That INSERT doesn't look like it actually carries the data you want put in. With respect to other possible solutions: Have you got good reason not to give the different sites access to the master copy of the table? That would be a lot simpler. If you've got enough authority over the MySQL server, you could make a separate database and user for that alone. If you have a single user who has the right permissions on all the databases (read the master, write the slaves) you could do the copy within MySQL, which would keep the PHP simpler. If you have sufficient access to the machine, you could Cron the MySQL statements through the command-line client and do away with PHP completely, which makes the project much simpler and should reduce the overhead of running the update task considerably. If you are copying, dropping the table to lose the old data is only necessary if you change the schema of the master table, otherwise TRUNCATE is simpler (and probably quicker). Bear in mind if you decide to DROP that you will need to CREATE it again, so you either need to hard-code the table schema into your update script or make the script smart enough to construct a CREATE statement based on the schema of the master. The MySQL you want to pass (either through PHP or into the MySQL client) probably looks a little like this: TRUNCATE `db2`.`table_name` ; or if you're dropping: DROP TABLE IF EXISTS `db2`.`table_name` ; CREATE TABLE `db2`.`table_name` ( /[insert column and key declarations]/ ) TYPE = MYISAM ; then (assuming you can get access to both from the same user) INSERT INTO `db2`.`table_name` SELECT * FROM `db1`.`table_name` ; Hope some of that helps.

Simple backup solutions
by Eur Ing Chris Green 24 Feb '07

24 Feb '07

What do others here use to backup data on their machines (if anything!)? I'm looking for something a bit more friendly (and clever) than just tar or rsync but nowhere near as big and complex as backupbuddy or backupPC. So is there anything 'in between'? I'd like a GUI that allows me to choose directories that I want backed up and sets up a regular backup of those directories. Ideally it would allow me to have different 'levels' of backup so that, for example, very important stuff like the company accounts database would be copied offsite and frequently and less important stuff (like say /home) would just be copied to a different hard drive, possible less frequently. I don't want total machine backup, if the machine or a disk expires I'll reinstall, that's only time consuming. All I want to backup is actual data which would be near impossible to rebuild. If there's nothing ready made I'll just write a script using rsync, it wouldn't be too difficult. -- Chris Green

Sounds fabulous. Just what I was thinking when I mentioned it in a earlier post. I will add the books from my store at the weekend. The only trouble is that I have no transport so if someone in Norwich wanted to borrow one of my books, they would have to come and get it somehow.

PHP/MySQL help please
by Tony 24 Feb '07

24 Feb '07

I have set up four websites for local charities but they want the same events to appear on all websites. The sites have all been set up using Joomla and are on the same server but different domains. A common connection to MySQL is not a problem. What I am trying to do is collect data from the MySQL database of the main site and send it to the other sites using PHP (will use a cron job when I get the script working). There is only one table that needs to be transfered. The script I have come up with so far is: <?php $db_host = "localhost"; $table1 = "jos_extcal_events"; $table2 = "jos_extcal_events"; $db_name1 = "midsuffo2"; $db_user1 = "user1"; $db_pw1 = "password1"; $db_name2 = "tbrn1"; $db_user2 = "user2"; $db_pw2 = "password2"; $resource1 = mysql_connect($db_host, $db_user1, $db_pw1)or die ('I cannot connect to the database because: ' . mysql_error());; //select query to get all the data from resource 1 mysql_select_db ($db_name1)or die("Unable to select database $db_name1"); $sql = "SELECT * FROM $table1"; $query = mysql_query($sql, $resource1); for ($i=0;$i<($result = mysql_fetch_assoc($query));$i++) //insert data into $resource2 $resource2 = mysql_connect($db_host, $db_user2, $db_pw2)or die ('I cannot connect to the database because: ' . mysql_error());; mysql_select_db ($db_name2)or die("Unable to select database $db_name2"); { mysql_query("INSERT INTO $table2"); } mysql_close($resource1); mysql_close($resource2); ?> Although it runs without error, it doesn't do anything! I would prefer to drop the old table and create a new one otherwise deleted events would stay on the client sites. Can anyone help or suggest an easier way of doing it? Many thanks Tony

looking for webcam
by David Reynolds 23 Feb '07

23 Feb '07

Hi, I'm looking to test a particular model/range of webcam with a piece of software called Delicious Library [1] and wondered if anyone had one that I could borrow / buy for not much cash to see if it works. The type I'm looking for is a Logitech 4000 / Zoom. Basically from what I read it needs to be a Logitech with manual zoom. If anyone can help, it'd be much appreciated. Thanks, Dave [1] http://www.delicious-monster.com/ -- David Reynolds david(a)reynoldsfamily.org.uk

What I meant was that if you edit the HTML rather than use the GUI, the HTML is all bunched up and not spaced out so that it is easy to read for those of us out there that are rookies and will struggle anyway.

OK - from the Edit (GUI) type link, to add a row to the table, right click in any cell, hit Insert Row - works very similar to any other editor that does tables :) (Just checked that it worked as I expected, because I'm a "Edit (Text)" person, I like wiki markup and find it quicker and easier than using the GUI). > Please can we make this Wiki user friendly to people who cannot use > HTML.
