Thanks Gary. Seems despite all efforts, a good tutorial can’t stop a developer being a twit. I omitted to update the version in config.xml to 0.2.0. Now works perfectly!

make sure your mysql4-upgrade-0.1.0-0.2.0.php file begins with < ?php
i didnt bother to write it in there but you need it for php instructions remember?
Also, if it still doesnt work
go into your core_resources table and change your version back to 0.1.0 and then go to to your admin page again, that’ll trigger the update script. I’ve just tested the scripts, it works just fine.
Good luck!

Great Article!

Using Magento 1.3.2, come hell or high water I’ve been unable to execute the upgrade script. core_resource still says 0.1.0 – any suggestions?

Absolutely fantastic article series. Thank you so much for publishing it. I feel like I have a much better handle on Magento now. One thing I wanted to mention was that for me, on 1.2.1.2, in config.xml, I had to use: Twits 100 adminhtml/twit instead of Twits 100 admin/twit Thanks again, and keep up the fantastic work! -Colin

This is a great article. The detailed information helped me solve my problem where I couldn’t get my blocks to display when there were located in the /app/code/local directory but they would display fine from the /app/code/core.

After a day of trying I really appreciate the detail included within this post and the fact it isn’t just a repeat of all the other basic “override a core block” blog entries.

Many Thanks.

I thought no one was ever going to write about writing extensions for Magento!

Thanks. Some really useful info here.

Using magento 1.3.1, the created table’s name was “twit_id” (instead of “twit”, problems with next part).
To avoid this problem, just skip the table creation (step 5 to 7).
If it’s to late, you can copy the mysql-upgrade script to “mysql4-upgrade-0.2.0-0.3.0.php” and change version in “config.xml” at the end of next part (reproduce step 5 to 7, table name will be bound to “twit”)
