entering article images that doesnt exist
I accidentally entered a article image id that didn’t exist and my blog went blank! Is this the default behaviour? Isn’t there a way to test to see if the image actually exists and the bail nicely?

Re: entering article images that doesnt exist
Hmmm that’s new … in admin make sure in “admin > basic > production status” is set to live … then nothing like that should happen …
I tried with debugging/testing/live in 4.04 on my site … and site shows up in all cases but lot of broken messages in first two…

Re: entering article images that doesnt exist
FAQ: How should I ask for help on the forum?
What does “went blank” mean? Change your production mode to Testing/Debugging. Do you get any error messages?

I have my site set up to debugging and I just get an totally empty page (no output). also the error log doesn’t say anything.
I’m using PHP 5.2.1

Re: entering article images that doesnt exist
And this was just a ID number for an image that doesn’t exist?
I’ve no idea why that would happen, but it definitely should not.
The next thing is to examine exactly what page and forms that article is using. Put an id for an image that does exist, then post a tag trace.

I’m running PHP 5.2.1. Could that mean anything?
I cant post a tag trace since I’m not getting any page back. I’m simply getting a completly blank page. Nothing in view source.

Re: entering article images that doesnt exist
I think I found the problem:
In line: http://dev.textpattern.com/browser/development/4.0/textpattern/publish/taghandlers.php#L2060
$rs = safe_row(‘*’, ‘txp_image’, ‘id = ‘.intval($image));
this is NOT return empty on my system. It’s returning:
Array()
so:
$rs = safe_row(‘*’, ‘txp_image’, ‘id = ‘.intval($image));
if ($rs)
will validate to true!

No, an empty array evaluates to zero/false.

You didn’t read that properly (further emphasis added):
Put an id for an image that does exist, then post a tag trace.

Sorry you’re right. The problem is in the trigger_error.
http://dev.textpattern.com/browser/development/4.0/textpattern/publish/taghandlers.php#L2113
not sure why, but having that line makes my php return an empty page.

Re: entering article images that doesnt exist
What page(s) show as blank? Just the individual article page or others too?
