In theory, you could modify the store.php script so that when sending the current TW contents to store.php, you also send the document.lastModified value. Then, store.php could compare that value against the date of the hosted version of the file to ensure that the date on the server is not more recent than the date sent from the currently loaded document. If it is more recent, it could reject the save and return an error. Then, to resolve the problem, you would export the changed tiddlers from the TW in the browser (saving the export file locally), and then reload from the server, and then import the changes to merge them. Then save to the server again. I say "in theory" because I don't have access to the version of store.php that you are using, and I also don't have a server on which to test the changes. Some possible issues: * the document.lastModified value is only valid if you loaded the document via http or https protocol. If you are working from a local file copy, that value will be the current date/time, regardless of when the file was actually saved. * WebKit returns the time string in UTC; Gecko and Internet Explorer return a time in the local timezone. Thus, you might have to install the "Browser Sniff" plugin (from the TW Official Plugin Library) in order to detect which browser is in use, and then do some conversion to match the time in use on the server (which might also be either UTC or local time) see https://developer.mozilla.org/en-US/docs/Web/API/Document/lastModified -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
