Summary |
Browser refresh causes duplicate inserts. |
|
Description |
When the user clicks refresh on the browser after an insert PME inserts a duplicated record in the table.
I havent found a way to avoid it (aside from using a unique index, which is not always posible).
In other php apps i have used something like:
if (!isset($_SESSION['pcount']))
$_SESSION['pcount'] = 0; //$pcount is a "form post counter"
function formrefresh() { return $_REQUEST['pcount'] !=
$_SESSION['pcount']++; }
and then when building each form I add:
<input type=hidden name=pcount value=<?=$_SESSION['pcount'] ; ?> >
So before taking action I can check that the user is not submitting a form like this:
if (!formrefresh() ) {
//insert the record
} else {
// show a new empty form or redirect to the list of records
}
Do you think it would be easy to add this kind of feature to PME ?
Thanks,
Mariano |

[this is not website/homepage related, more docuemntation issue.]
yes,
have a look at trigger insert before (to stop the insert proccess), and $opts['cgi']['persist'] option (to keep the hidden variable). |

Well, concerning to addition of this into core class, I do not thing it is a good idea. I do not want to mess/bloat core class with things like $_SESSION and so on.

Agreed.
This is (as michal said) a documentation issue. |
