Having trouble with Live Preview
Development and Programming
Hey all! I seem to need some help. Possibly related to this bugfix PR I made: <https://github.com/ExpressionEngine/ExpressionEngine/pull/5120> I’m excited because the PR just got accepted today 🙂 but even if I patch my local site with the fix, I now have Live Preview showing a 404 page in the preview pane, and only for the channel in question. I’m not sure how to go about debugging this issue. Will add some details in a thread.
I have a News channel and an Events channel. These are both configured as Listing channels within Structure. Previews for the News are working just fine but not for Events. I got TypeError before the patch, but once I apply it, the preview pane is showing a 404.
For the Events channel: some of the client’s events have sub-pages within them. To get that working, I am using Freebie. I wonder if that’s what’s breaking the live preview?
For the News channel, the “Preview URL” field is blank and it works just fine. For Events though, I get 404s whether I leave it blank or configure it to events/{url_title}
Have you got any custom statuses in use?
If you have you’ll have to add them to the channel entries tag in your template. Here’s one I made earlier that lets preview see entries that are closed or “Draft” status using the status parameter and the is_live_preview_request variable:
status="open{if is_live_preview_request}|Draft|closed{/if}"I do have one custom status, but it isn’t assigned to this channel. I could still try that maybe!
Okay, I think I figured it out. Seems like a bug in Freebie.
My template relies on what’s in freebie_1 and freebie_2 but those variables never get set by freebie while in live preview.
For now I’ve found a workaround by using conditional logic. Thanks for the suggestions.
That status variable hint is incredibly helpful. Didn’t know there was a live preview variable I could check. You helped me solve another problem that I hadn’t even realized I was having, haha. Thank you @roballen.
