Check box and array problem

[harman]

Hi!
i have a dynamic form

while ($row = mysql_fetch_object($resultall)) {
$ct++
...
$htmlr .= "<input type=hidden name=\"color_id[]\" value=\"$row->prod_color_id\">";

$htmlr .= '<td>$row->prod_color <input name="avail[]" type="checkbox" value="1" /></td>';
}

The form looks like this:

<save button>
Color Name1 <check box>
Color Name2 <check box>
...
...
<save button>

This is my update code

if($POST['update']){
for ($i=0; $i < $POST[ct]; $i++){
if($available[$i] == 1){
$sql = "INSERT INTO cds_prodavail_colors (prod_id, prod_color_id) VALUES($prod_id, $color_id[$i])";
}}}

the problem is the array avail will only be set if the check box if clicked, and so so my color_id array and avail array are not in sync. is there a way to rig the check box so that the avail array is set to 1 if its checked else if its not checked it stores some digit(except 1) in the avail array

I have to update the whole form with one submit button, if anybody has any input please let me know....thanks

setup the array beforehand so you know what the possible choices will be:

$checkboxes = array(
	'one',
	'two',
	'three',
	'four',
	'five'
);

echo '<form action="' . $_SERVER['PHP_SELF'] . '" method="POST">';

foreach ($checkboxes as $value)
{
	echo '<input type="checkbox" name="form_checkboxes[' . $value . ']" value="Y"> ' . $value . '<br>';
}

echo'
<input type="submit" name="submit" value="submit">
</form>
';

if (isset($_POST['submit']))
{
	foreach ($checkboxes as $value)
	{
		echo 'checkbox ' . $value . ' ';
		if (isset($_POST['form_checkboxes'][$value])) {echo 'is checked';}
		else {echo 'is NOT checked';}
		echo '<br>';
	}
}
