see this new page. That allows me to inflict pain on testbed developers while we work out any kinks. These new pages implement an XML interface to experiment creation. Some new files: beginexp_html.php3: A wrapper for the actual beginexp form. This page includes the form, and then invokes the XMLRPC backend page. beginexp_form.html: The original form code, split out from beginexp and turned into a module that can be included into another file. It is slightly reorganized to make it easier to include as a module. The idea is that the plab_ez form will be recast in this model, reducing some redundant complexity. beginexp_xml.php3: The XML backend. The idea is that the html page packages up the form arguments as an XMLRPC message, and invokes this page with the XML goo encoded in the URL. It also passes along the uid/cookie so that the authentication happens properly (https of course). The page decodes the URL into PHP datatypes, and does much of the same argument checking that beginexp used to do. Errors are stored up in the same manner, but instead of spitting back html, it now spits back a "structure", encoded in XML so that the _html page can put up a new form. Basically, all output is sent back via an XML encoded structure and displayed in a form that the invoking script deems appropriate. This gives us a pure XMLRPC interface, which we wrap with a form interface so that it looks just like it did before. The next step is to provide an alternate front end, but that will require some certificate stuff that I have not worked out yet. Oh, one more item. The syntax check stuff has been altered a bit. Instead of invoking the beginexp page, which meant a zillion special tests, I now invoke nscheck.php3 directly from the button. Took a few extra lines of Javascript to do this, so watch out for problems there too.
