Ok, I can't get this right...
Have the following code:
<?
$choices = array(1 => 'dog', 2 => 'cat', 3 => 'mouse', 4 => 'frog');
if (is_array($_REQUEST['animals']))
{
// get the number of selectcases
echo "get the number of selectcases: " . count($animals) . "<br>";
// get the number of provided selects from select with name "2"
echo "get the number of provided selects from select with name
\"2\": " . count($animals[2]) . "<br>";
// test to print some data
echo $animals[2][0]. "<br>";
echo $animals[2][1]. "<br>";
echo $animals[2][2]. "<br>";
echo $animals[2][3]. "<br>";
}
?>
<form method="post" action="<?= $_SERVER['PHP_SELF'] ?>">
<select multiple name="animals[2]">
<option value='1'>dog</option>
<option value='2'>cat</option>
<option value='3'>mouse</option>
<option value='4'>frog</option>
</select>
<select multiple name="animals[4]">
<option value='1'>dog</option>
<option value='2'>cat</option>
<option value='3'>mouse</option>
<option value='4'>frog</option>
</select>
<input type="submit"></form>
Why does it not work?
// get the number of selectcases
echo "get the number of selectcases: " . count($animals) . "<br>";
This works great
// get the number of provided selects from select with name "2"
echo "get the number of provided selects from select with name
\"2\": " . count($animals[2]) . "<br>";
But this doesn't...
Thankful for any help,
/Victor
