That's not mentioned in the tutorial so, naturally, we didn't know to expect it.
Can you clarify how many records the http://www.webassist.com/tutorials/Create-a-multiple-record-update-form tutorial is designed to work with so that we may, at least, test that it is actually working at all?
We are the host but we have no idea how to change the php.ini file. So that I understand what you're suggesting we try...
1) We need to edit the php.ini file to allow the post array to contain more than 1000 elements
2) We need to edit the php.ini file to increase the post_max_size - to what size would you recommend?
We would like to have all of the products (342) listed on one page and be updatable via one form - surely that's the point of "Update Multiple Records"? I'd appreciate your assistance in helping us achieve that aim.
