Error message when trying to upload a photo to CLOG

Hi Jools,

Tonight I tried to add a photo to the CLOG page for

C016

.

When I did, the photo was rejected with this message:

Something went wrong, the selected new position is different from number of actual images. (seq_no=2, image_count=2) - please report.

Sorry,
Eric

Okay, that's weird. In spite of the error message, the picture upload appears to have been successful. That is very confusing.

Cheers, Eric

Seems like it was old bad data. Each image has a sequence number (seq no) which determines the order in which the images are shown. The best, single first larger image is shown is seq 1 and so on. The error is when the sequence number has gaps/shows an incorrect total. Historically there was an issue when this happened a from time to time which I never really got to the bottom of but appeared to resolve by some change I made. My suspicion is when the back button or browser history functions are used in conjunction with the admin pages.

Anyway, the image was added and looks OK to me. I also re-ordered the images on the page which is a good check everything is OK.

So, not a bug in the code, rather an error in the data which is fixed. That said, you're right to be cautious, this can cause merry hell with species where there are lots of images. Hopefully, we have seen the last of those (although, IIRC, Synodontis brichardi is one I need to fix at some point).

Cheers,



Jools
