Working with checkboxes?

[Anon]

I'm trying to pass the values from a group of checkboxes on a form to another page for PHP to process.

I have my form setup so the POST action is the other page.

When I submit the form, if I have checked multiple values in the checkbox only the last value entered is actually returned. Now granted all of my checkboxes have the same name (but not the same value of course), but I'm used to doing it that way with other tools.

Do I have to name each checkbox a different name and step through each checkbox? Surely there's an easier way.

Did you use MULTIPLE?
ex.

Colors:
<select name=State MULTIPLE>
<option value=red>red</option>
<option value=green>green</option>
<option value=blue>blue</option>
<option value=yellow>yellow</option>
</select>

Php is a little different than some other scripting languages. The checkbox name is a little odd, and you only get back the ones that were checked. Take a look at this example:

<?php
if (isset($box) ) {
while (list($i, $v) = each ($box) ) {
echo "Posted Array Index: $i Value: $v <br>";
}
}

?>
<form action="testphp.php" method="post">
Box 0: <input type="checkbox" name="box[]" value="0"><br>
Box 1: <input type="checkbox" name="box[]" value="1"><br>
Box 2: <input type="checkbox" name="box[]" value="2"><br>
<input type="submit">
</form>
