First, I send the id to rec_update.php file like this:
location.href="http://localhost/pk/rec_update.php?id="+id;
On rec_update.php file, I access that value like this:
$id = $_GET['id'];
Now, I want to send this $id to rec_update1.php file. which can be called by clicking a button. On button I have applied a javascript function from where page will directs to rec_update1.php How do I get this value on another php file.
HTML / HTTP is stateless, in other words, what you did / saw on the previous page, is completely disconnected with the current page. Except if you use something like sessions, cookies or GET / POST variables. Sessions and cookies are quite easy to use, with session being by far more secure than cookies. More secure, but not completely secure
.
Session:
<?php
//On page 1
$_SESSION['varname'] = $var_value;
//On page 2
$var_value = $_SESSION['varname'];
?>
Remember to run the session_start() statement on both these pages before you try to access the $_SESSION array, and also before any output is sent to the browser.
In rec_update.php
<script>
location.href="http://localhost/pk/rec_update1.php?id=<?php echo $id; ?>";
</script>
And in rec_update1.php
$id = $_GET['id'];
