If you have an associative array:
Array
(
[uid] => Marvelous
[status] => 1
[set_later] => Array
(
[0] => 1
[1] => 0
)
[op] => Submit
[submit] => Submit
)
And you want to access the 2nd item, how would you do it? $arr[1]
doesn't seem to be working:
foreach ($form_state['values']['set_later'] as $fieldKey => $setLater) {
if (! $setLater) {
$valueForAll = $form_state['values'][$fieldKey];
$_SESSION[SET_NOW_KEY][array_search($valueForAll, $form_state['values'])] = $valueForAll; // this isn't getting the value properly
}
}
This code is supposed to produce:
$_SESSION[SET_NOW_KEY]['status'] = 1
But it just produces a blank entry.
Use array_slice
$second = array_slice($array, 1, 1, true); // array("status" => 1)
// or
list($value) = array_slice($array, 1, 1); // 1
// or
$blah = array_slice($array, 1, 1); // array(0 => 1)
$value = $blah[0];
