#1062 - Duplicate entry '0' for key 'PRIMARY'

[eluser]kaloyan[/eluser]
It seems that when I make any change in any of the menus Operators, Insert, Sql...and after that go to some of the other menus, and then come back to the previous one, there is nothing remaining of what I've set (written) in the blank places...why does the information lose?

You see A_I column there with check box beneath it?
That is autoincrement key. Check it and click Save bitton immediatelly after.
That should solve your first meant problem.

I found the auto increment option, but when click on Go, this error appears:

You are not on right action page.
There is no Go button, but Save one.
Check again your image before this one.

I found the A_I, Thank You!
no errors now
it's so simple (facepalm)
God bless You

[eluser]Tpojka[/eluser]
Glad you succeeded.
Just read errors and copy/paste it in google search box.
Believe or not, you are not first one with such a kind mistake.

Of course, practice is very important because practice is teaching us what should be avoided on time.

[eluser]kaloyan[/eluser]
yes, practice all the time, makes the thing u learn a part of yourself, ye i'll google the errors first before posting here

I just made an account on this site so I could thank you and Ryan for solving this issue. It was for an Opencart database on a site that makes over $500,000 annually and having this function not work was killing it.

THANK YOU BOTH SO MUCH

phmyadmin when creating fields with a primary key will show a checkbox named ai for auto_increment
