[Resolved] getting checkbox value

Jyotsna

Can anyone tell me why the index of $sele_depart[$i] is undefined after I pushed the "editar" button?

 include("header.php");

//$departamento=array();

I think you mean

$_POST['sele_depart'][$i]

but any checkbox that's not ticked won't be listed in the array. For example, if the checkbox "sele_depart[3]" is not checked, there won't be a $_POST['sele_depart'][3], and you'll get an undefined index when $i=3.

If you want an array of the id_dep values that are checked, you can have

$sele_depart = array()
foreach($_POST['sele_depart'] as $checked)
{ $sele_depart[] = $checked;
}

That's assuming you don't actually care about the exact value of $i, only in the values of the checkboxes.
