How can I redirect to my site from another?

I have developed a site named www.printingchemical.com, full of information portal on chemicals.

I have another two domains.
How can I make a code to redirect from that two domain to my www.printingchemical.com site?

Waiting for this code.

Thanks in advance.

 

That should work if I understand you right.

 

Put this in a .htaccess file in the root folder of your other two domains

RewriteEngine On
RewriteBase /
RewriteRule ^/?(.*)$ http://www.printingchemical.com/$1 [R=301,L]

Code (markup):

 

code:
<?
echo'<script>window.location="example.com?example";</script>';
?>

 

Javascript can be disabled, so its not reliable.

Theirs many ways:

1. .htaccess

2. php header location

3. html meta refresh tag

4. javascript - window.location

But i'd recommend 1 and 2 since they don't rely on client-side configuration, theirfore more reliable.

 

This code works under Java scripts with PHP Code
Example:

<?
$p=$_GET['p'];
$display ="SELECT * FROM tbl_data WHERE p='$p'";
$result=mysql_query($display);
$display= mysql_fetch_array($result);
echo'<script>window.location="index.php?menu";</script>';
?>

index.php?menu exgo to menu page)

 

header is very reliable in my experience.
can also be used for refresh which is useful in conditional functions.
