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.

    Implement the Google AJAX Search API

    Let's be honest...WordPress' search functionality isn't great. Let's be more honest...no search functionality is better than Google's. Luckily for us, Google provides an awesome method by which we can use their search for our own site: the Google AJAX Search API.

  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
