adding to existing form

tunks

hi again 🙂

i've got a html table produced by php script
how to append to the existing record (add) with the same php script?

<?php
$i=0;
for ($n=0; $n<5; $n++)
{
?>
<table>
<tr><td><?php echo $n; ?></td></tr>
</table>
<?php
$i++;
}
?>

value $i is already 5
if we call the script again, how to append the table?

thanks for any help in advance

Hi, maybe you could use sessions - if you register a session and give it a value, increment it and reload the page the new value is available.

sessionTest.php
<?
session_start();
session_register("SESSION");

if (! isset($SESSION)) {
$SESSION["count"] = 0;
echo "<li>Counter initialized, please reload this page to see it increment";
} else {
echo "<li>Waking up session";
$SESSION["count"]++;
}
echo "<li>The counter is now $SESSION[count] ";
?>

You could use something similar

that works for a sessionvaribale on the same page.

but does not work for form $_POST method.

any idea?

the basic is like a shopping basket.

keeps adding up when we click buy

It's not just current to that page, if you include

session_start();
session_register("whateveryoucalledyoursession");

at the start of whichever page you use you get access to, and can modify it.

ok.

but session variable cannot be used if qe use the form _POST method..

any idea of replacing the session with $_POST?
