$_POST values with a dynamic list

[eluser]tomcode[/eluser]
Well, one solution would be :

1. suffix all names / ids with numbered [], also the submit buttons

Code:

<input type="hidden" name="img[0]" value="xxxx" />
    <input type="submit" name="submit[0]" value="Submit" />

    <input type="hidden" name="img[1]" value="xxxy" />
    <input type="submit" name="submit[1]" value="Submit" />

        ...

2. then check the $_POST array which submit button has been used

Or just build multiple forms with an identifier in the submit URL

Code:

form_open('controller/method/form_ident);
