I have a simple question but yet i don't know. I would like to display message first before redirect to other page, but my code just directly redirect the page without display the message, or the display time is too short am not sure.. my code as below.. pls advise. thank much.
echo "Please Log In First";
header("location: login6.php");

RegisterStartupScript(this, this. GetType(), "alert", "<script> alert('User details saved sucessfully');window. open('frmDisplayUsers. aspx');</script>", true);
In PHP, when you want to redirect a user from one page to another page, you need to use the header() function. The header function allows you to send a raw HTTP location header, which performs the actual redirection as we discussed in the previous section.
It is quite simple to do a page redirect using JavaScript at client side. To redirect your site visitors to a new page, you just need to add a line in your head section as follows.
You can't do it that way. PHP header must sent out before any content, so the correct order is:
header("location: login6.php");
echo "Please Log In First";
But these codes will redirect instantly and wouldn't let you see the content. So I would do the redirection by JavaScript:
echo "Please Log In First";
echo "<script>setTimeout(\"location.href = 'http://www.example.com';\",1500);</script>";
You can use header refresh. It will wait for specified time before redirecting. You can display your message then.
header( "refresh:5; url=login.php" ); //wait for 5 seconds before redirecting
