How to retain array content if I use $PHP_SELF

[THL]

Hi,

I want to reload a PHP page so that it could execute a function. However, after reloading, the array seems to display, could anyone suggest me a solution, here is my coding:

<?php
// the array
$amt = $_POST['info'];
...

function update() {
foreach ($amt as v1) {
.....
}
};
?>

// html body
<form name="form1" method="post" action="<?php echo $PHP_SELF ?>">
...

<td width="99"><input name="Confirm" type="submit" id="Confirm" >
<input type="hidden" name="action" value="action_name">
<?php echo '<input type="hidden" name="info" value="$amt">'; ?>

// end of the html

The error appears inside the function which shows that the "foreach" loop is invalid after the page is reloading.

Thank you very much.

You have to send the variable to function, otherwise it doesnt regognize it. Other way is that you use $_POST['info'] inside that function..

1. use update($amt);

   function update($amt) { 
   foreach ($amt as $v1) {
   ..

   Or use update();

   function update() { 
   foreach ($_POST['info'] as $v1) {
   ..
