Question

I am looking to create an SEO friendly URL after a filter has been submitted in an html form.

After playing around for a while I have found a way, however I was wondering what otehr people think of it as I’m new to development.

I have added some rewrite rules in the .htaccess file to make the urls more friendly. Examples below:

Original URL:
site-nane/list.php?brand=brand1&min-price=0&max-price=2000

URL after rewrite:
site-name/section/brand1/0-200

Currently I have the form that submits the information to a separate php page which collects the variables and creates a new url from it which then redirects with a 301. Example of php below:

$min = $_GET[‘min-price’];
$max = $_GET[‘max-price’];
$brand = $_GET[‘brand’] ;

header ('HTTP/1.1 301 Moved Permanently');
header('Location: http://site-name/section/' . $brand . '/'. $min.'-'.$max );
exit();

As you can see it collects the info and takes you back to the page and declares the previous page has permanently moved.

Questions:

1. Although this maybe quite primitive, will this still be ok to use without causing too much trouble?

2. Will google hate me for creating so many 301’s

3. Just noticed the code header(“Location: /foo.php”,TRUE,301); would it be best to use this or no difference?

Answer 1

1. Yes, I see no issues with your solution. Even if malicious user input was given it would just redirect to a non-existing page.

2. I don’t think so. You already use the right code 301 instead of the default 302 which might cause some trouble / did create some havoc with regard to Google, stolen PR and SEO

3. Using header(“Location:…”, true, 301); is advisable. This way php could automatically make decisions based on the environment. E.g. if using an HTTP/1.0 connection php could send the 301 code with HTTP/1.0 instead of your fixed HTTP/1.1 in your solution. But still, either way is fine.

But one question: why don’t you link directly to your nice URL? mod_rewrite which you are using would then already take care of assigning the parameters given with the URL to variables that you could access via $_GET as usual.
