Hi Rouslan,

Hi Thilanka,
> off the top of my head I can think of an issue that can be solved with
> some ajaxification. On tbl_structure page, if you use the "Add * index"
> actions that are available in the "More" dropdown corresponding to a
> column in the top table. You will be dropped to sql.php, which will show
> the table structure page, but it will not include "tbl_structure.js", so
> all the ajax actions on this page will be broken. Of course, if the "Add
> * index" links would be ajaxified, this would no longer be a problem,
> because we would not leave the tbl_structure page.
> Please do not take the following badly, but rather as constructive
> criticism and as a way to learn from your mistakes. I find that some of
> the ajaxification work that you did this summer was less then optimal.
> As an example, let's look at some issues with the work that you did on
> the index editor.
> First of all, you create a custom slider to hide the indexes table. This
> was unnecessary, because we already have a PHP function that takes care
> of this, which also respects the $cfg['InitialSlidersState']
> configuration setting.
> Another issue was that in every ajax reply the top menu was included and
> then removed from the reply via jQuery. This, of course, causes transfer
> of waste data and it's better not to send it in PHP altogether.
> Then there was an issue when a user requested to add a column to the
> index editor: the browser fired an HTTP request of the form to the
> server, just to get the same form back with an extra empty field. Of
> course, this action can be done on the client side by just cloning a row
> from the table.
> So, I fixed all of the above and I also cleaned up the layout of the
> editor in order to use less horizontal space and appear more
> user-firendly. I invite you to look at these changes so that you can
> learn from them. It's commit 863819cbdd759 and the following 10 commits
> after that.
> By the way, if you need a mentor or just some guidance, please feel free
> to contact me at any time. I would be glad to help you with any issues
> you may have and/or review your code.
> Bye,
> Rouslan
Sorry for the delayed reply I'm sending. I went through your above
mentioned commits and observed how was it implemented. Now I realize that
some of the previous work I did have optimization problems. I'll go through
the list of functionality I have implemented and come up with a optimized
solution for them. Thanks for the guidance you gave.
