如何在数组中存储每个表单的POST值？

Question

Basically the code is supposed to be simple yet it is not working! First page:

<?php
$i = 1;
$var;
while($i != 10)
{
    $var="
    <form id='upload' action='test2.php' method='POST'>
        <input type='hidden' name='test' value='{$i}'>
        <input class='buttom' name='album' id='submit' value='Go to album' type='submit'>
    </div>  ";
    $i = $i+1;
    echo $var;
}
?>

Second page:

<?php
echo $_POST['test'];
?>

when I run the code I always get the last value only (9) ... I need to have different value for each button .. can you help me?

You don't need multiple forms or hidden inputs to achieve this. You can just use buttons, and set their values to $i.

echo "<form id='upload' action='test2.php' method='POST'>";
for ($i = 0; $i < 10; $i++) {
    echo "<button type='submit' name='test' value='$i'>Go to album</button>";
}
echo '</form>';

In test2.php, $_POST['test'] will have the $i value of the button you clicked.
