We have a WP plugin here
[url removed, login to view]
Now we need to add a new section to plugin's configuration page.
Detailed description of the task is here: [url removed, login to view]
In the nutshell, you need to add a search form to the page and then work with results through AJAX.
The search form sends data to WP, then WP forwards that data to a different domain, get an RSS feed and return it back to the page, all through AJAX. The admin will choose items of interest from search results and their IDs should go into certain fields on the config page. Sounds complicated, but it isn't.
Please, install the plugin and go to the configuration page.
Do you see Feed text box?
You need to paste something in there. To do so you need to go to another website and do a search there. Too hard. We need to bring the search to the same page and make this text box populate automatically.
See the point?
This is an open source project.
