attaching query stirng to the file in iframe src

[varai]

Hello,

I'm trying to do like "Welcome username" as in phpbuilder for my website.

Welcome username should appear in every page once the user signs in.

I want to put this welcome username in the page_header.php (this appears on everypage with the logo).

There is a sign in link on page_header.php. Once the user clicks that, it goes to sign_in.php. After the user enters login and password and clicks the continue button, the index.php (the main home page) should display with "Welcome username".

How can I pass the username as a query string from sign_in.php into page_header.php through index.php? Can someone tell me the best method to go about this using php or javascript?

I have put page_header.php in iframe in index.php. LIke the following:
index.php

<div>
<iframe src ="/page_header.php" width="100%" height="129" scrolling="no" frameborder="0">
<p>Your browser does not support iframes.</p>
</div>

sign_in.php

function mySubmitFunction(which)
{if (window.location.search=="?sign_in_flag=true")
  { 	which.action="index.php";
	which.submit();
	}
else
.......	

page_header.php

<div>Welcome username</div>

thank you.

solution you may not like, but there is no good reason to use iframes anymore, and many good reasons not to (like your issue above)

hi dagon,

how can I pass a query string from sign_in.php containing the user name back to page_header.php?

I have no problem passing the query string to index.php with windows.location.href. If I do the same for page_header.php, only the page_header gets displayed.

I don't know on how to attach a query string containing javascript variable to <?php include("page_header.php"); ?>

I hope u get what I mean

thank you.

the following is my code in sign_in.php

if (window.location.search=="?sign_in_flag=true")
  {  email_str=which.email.value;
	username=email_str.substr(0,email_str.indexOf("@"));
	alert("username:"+username);
	   [COLOR="red"]window.location.href="index.php?username="+username[/COLOR];

I have no idea on how to pass username to page_header.php.

index.php

<script type="text/javascript">
if (window.location.search!="") 
    {href_str=window.location.search;
	[COLOR="Red"]username[/COLOR]=href_str.substr(href_str.indexOf('=')+1,href_str.length);
	    }	
</script>
<?php
include("page_header.php");
?>

thank you.

Deal with it on the server. For the user to login and remain logged in, you will need sessions

session_start();
if (!isset($_SESSION['usename'])) {
	header('Location: http://example.com/login.php');
	exit;
}
require 'page_header.php';  # which can: echo 'welcome ' . $SESSION['username'];

Hello johanafm,

thank you soooo much for ur solution. 🙂

It worked out great.

I am familiar with session variables, however in this case I was very confused.
