passing arrays from one page to another

Anon

i am using a submit form to pass information about an array. i want to pass the array as well. this is what i have for the submit part

echo "<form action='$PHP_SELF?action=arraypass' method='post'>";
for ($i=0; $i<$left; $i++) {	
	print_r($number[$i]);
	print(": <input type=\"Checkbox\" name=\"name".''.$i.''."\" value=\"$number[$i]\">");
};
	printf ("<input type=\"hidden\" name=\"left\" value=\"$left\">");
	printf ("<br><input type=\"submit\" value=\"Submit\"></form>");

this is what i want to do with it, see what sections are checked and what now
for ($i=0; $i<$left; $i++) {
$name=${"name$i"};
if ($name)
$unselected[] = $number[$i];
};

right now, it does not see the array of $number

you should use a foreach loop when dealing with arrays.

A working standalone script I used for testing:

<?php
$left=5;

$number=array(14,754,132,26,12);

if($action=='arraypass')
{
for($i=0; $i<$left; $i++)
{
$name=${"name$i"};
if($name)
$unselected[]=$number[$i];
}
print_r($unselected);
}
?>
<head></head><body>
<form action='<?php echo $PHP_SELF?>?action=arraypass' method='post'>
<?php
for ($i=0; $i<$left; $i++) {
echo $number[$i].'<input type="Checkbox" name="name'.$i.'" value="'.$number[$i].'">';
}
?>
<input type="hidden" name="left" value="<?php echo $left?>">
<br><input type="submit" value="Submit"></form>
</body>
