Question

I have this form which i submit using ajax and jquery ,
well, i have this multiple checkbox from which i get some values.

Now i am doing an error here since the values of the checkbox are not being posted in the database..
Here is the html/php part :

  while($row = mysql_fetch_assoc( $result )) {
    echo '<input type="checkbox" value="'.$row['regione'].'" id="regioni_gestite_ag" name="regioni_gestite_ag[]">' . $row['regione'] . '<br>';
    }

This is how i get it with javascript:

var js_regioni_gestite_ag = $('input:checkbox[name=regioni_gestite_ag]:checked').val();

If i echo the value, i get undefined…
Why is it so?

Answer 1

Try this:

var js_regioni_gestite_ag = [];//[name="regioni_gestite_ag[]"]
if($('input[name="regioni_gestite_ag[]"][type=checkbox]:checked').length){
    // check if any checkboxes are checked
    $('input[name="regioni_gestite_ag[]"][type=checkbox]:checked').each(function(o){
        // get their values
        js_regioni_gestite_ag.push($(this).val());
    });
}

// clears all selected checkboxes
function clearSelection() {
    $('input[name="regioni_gestite_ag[]"][type=checkbox]:checked').each(function(o){
        $(this).removeAttr('checked');
    });
}

Hope this helps.
