ANOTHER THING. MAYBE IT HELPS YOU TO UNDERSTAND.
When I select the file, in the HTML on the input value attribute, it is written :
“url=C%3A%5Cfakepath%5Cmy-file.jpg&size=61018&type=image%2Fjpeg&width=1250&height=816”
Why is it written “fake path” ?
I HAVE DISCOVERED SOMETHING NEW :
When I don’t select any image… The form is submitted (without the image) even if I am admin or contributor.
The problem appears only when I select a file (basic windows uploader).
It seems that the acf form believes that I didn’t select any image.
Is it a bug ?
Now, I tried with admin account, it’s doing me the same thing.
Unbelievable !
