Question

Hello everyone
For 3 hours I can’t figure out how to save the picture through update? Everything else is updated quietly, except for the picture.
I pass the id of the image received via CFile->SaveFile

I'm passing the id of the image received via CFile->SaveFile

You need to pass there not an id, but an array obtained via CFile::MakeFileArray, because all methods work with this array.
