PHP Redirect Function

By  on  

After form submission or a page redirect is triggered, it's commonplace to redirect the user to a different page or to the same page, formatted in a different way. Usually, you'd complete this by coding:

header('Location:  destination.php');
exit();

This is a completely acceptable way to code your pages, but I prefer to use a redirect function instead. Why? It's much more readable, and quite honestly, I'm tired of writing the header('Location: ...'); code.

function redirect($url, $permanent = false) {
	if($permanent) {
		header('HTTP/1.1 301 Moved Permanently');
	}
	header('Location: '.$url);
	exit();
}

This function is incredibly easy to use and saves a lot of code.

  1. Do you use a plugin to highlight and format your php code?

  2. Shawn’s correct — you can go to the URL above to download the javascript and CSS files. I’m not using a WordPress plugin though — it’s easy to install on your own.

  3. Cool, I like the features it has over my current solution that I am using.

    Thanks.

  4. Ahm… As you’re already talking about the syntaxhighlighter… Why is the little “copy code”-snippet copying code AFTER it says “the code is in your clipboard now”!? Wouldn’t it make sense to copy it before the JS alert?
    Well, anyway – nice website Dave! I like it – and all the little code snippets are really nice. So simple, but helping a lot. Sometimes it’s harder to create them “the easy way”, so this really comes in handy. Thanks!

  5. Nice and thanx

    You can use highlight_string() in PHP to hightligt your code, or highlight_file()…

    Warning: Cannot modify header information – headers already sent by (output started at C:\wamp\www\bv\bookinsert.php:1) in C:\wamp\www\bv\bookinsert.php on line 139

  11. If you have problems with header function :

    header("Location:www.google.com");

    you can use this line if you are fans of JavaScript ( client side ):

    echo "location.href='http://www.google.com'";

    OR , use this line if are not ( server side ):

    echo '';

    Sorry for my English :-)

    You can run into trouble if you redirect using relative URLs. It should also be noted that
    RFC1945 requires a complete absolute URI for redirection, see: http://tools.ietf.org/html/rfc1945

  13. i have problem when i redirect the header location:-
    Warning: Cannot modify header information – headers already sent by (output started at /home/adnanakh/public_html/dcncaclub.org/admin/website_insert_back1.php:3) in /home/adnanakh/public_html/dcncaclub.org/admin/website_insert_back1.php on line 18
