PHP使用GET []从URL获取值[关闭]

Question

I am trying to develop products filters for an online store I am working on. An example of what I mean is http://www.riverisland.com/men/just-arrived. I have managed to get a JavaScript to populate the URL when the sizes are clicked on but failed to get them remove value from URL when unchecked.

My main question here is this. Assuming I have my URL as:

http://127.0.0.1/shop/dresses/?s=1&s=2&s=3

How do I get my PHP to extract the values from the URL? How do I format a SQL query to search the values gotten from the URL using any sample query?

Answer 1

An easier solution is this.

Format your URL like http://127.0.0.1/shop/dresses/?s=1,2,3 as suggested by @Andrey.Popov. Then do the below.

if(isset($_GET['s']) && !empty($_GET['s']))
{
    $e = sanitizeFunction($_GET['s']);
    $d=explode(',',$e);
}

$d now has all your $_GET['s'] values.

That's the easier way I have figured out and it works!
