I am very impressed with SafeCracker and have it working for an awards entry site.
I have set this up so that it always uses an url_title, and works as you expect. The url_title is taken from segment_4. If the entry doesn’t exist it makes it, and from then on it simply edits. Exactly as i want. BUT, i have started to notice some repeat entries (same url_title with one added digit).
I have replicated this by after submitting the entry for the fist time (ie making the new entry) if you click browser back rather than the buttons on the website that cause the pages to reload, then click save again it will create a new entry rather than edit the one with that url_title. I assume because it is simply going back in the cache, it keeps some hidden inputs in the form instructing to make a new entry? Obviously reloading the page fixes this, though I need to make this water tight.
Are there any checks i can do on submission to see if the entry exists?
Thanks
Mark
