In fact, my problem is solved. It was a too long fieldname because of the field and subfield. It’s working very nicely with field key. What I wanted to say it’s why associate a field name if I can’t use it. As I said, I used the input name in $_POST and $_FILES as field name. I created a loop foreach and I used the key ($key => $value) as the field name because it’s natural more than field key. I needed to go in table and look the field key in table associated with the field name. After, created a conditional to associate the right field key with field name. So, for me, it’s a wrong use.
It’s my opinion.
