I have a select multiple list that has a few items in it. It is a list of IP addresses for an ACL. People can add/remove IPs, and then save the list. However, unless you select an item on the list, $_POST[selectName] does not contain any values. How can I accomplish this? I know I can do this with javascript but I would rather stick to PHP.
Edit/corrected: You need JS. There is no way to send all (selected and not selected) options via POST. You have to programatically select all options before submission.
File with form (file1.php):
<script type=text/javascript>
function selectAll()
{
selectBox = document.getElementById(someId);
for (var i = 0; i < selectBox.options.length; i++)
{
selectBox.options[i].selected = true;
}
}
</script>
<form method=post action=file2.php>
<select id=someId name=selectName[] multiple>
<option value=123.123.123.123>123.123.123.123</option>
<option value=234.234.234.234>234.234.234.234</option>
</select>
<input type=submit name=submit value=Submit onclick=selectAll();>
</form>
File that receives POST (file2.php):
<?php
foreach ($_POST['selectName'] as $item)
{
print $item<br/>;
}
?>
