I have the last url segment of the following url
http://something.com/somefunc/10
that is the number 10;
My real problem is that I have a form that I need to post an action of the url
<form action="../something/somefunc/<?php echo $id>">
//some code
</form>
after receiving the posted stuff, I would like to still be able to get the id of the product under consideration. I think now that form's action url is the only way I know that can help retain such an id. Any help is appreciated, thank you.
[ UPDATE ]
Uhmmm, all the answers below are correct, don't know which one to choose as the best reply.
Something along these lines may work...
$url = 'http://'. $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
$parts = parse_url($url);
$path = $parts['path'];
$keys = explode('/', $path);
echo $keys[4]; // `corresponding to the 4th url word`
Hope this helps!
Sorry if I'm misunderstanding, but can't you get the ID of your posted form via the $_POST array? http://www.w3schools.com/php/php_post.asp
Alternately, if the ID is in a URL parameter, you can access it via the $_GET variable: http://www.w3schools.com/php/php_get.asp
您可以使用ID输入隐藏的输入
<input type="hidden" name="id" value="<?php echo $id; ?>">
1.You could pass the product id using POST as a hidden input in your form:
<input name="productid" id="productid" type="hidden" value="<?=$id ?>">
and in the page you post to:
<? if (isset($_POST['productid'])) $id = $_POST['productid'] ?>
2.Alternatively use GET & pass it on the querystring
action="../something/somefunc/[processingpage]?productid=<?=$id ?>"
and in [processingpage]:
<? if (isset($_GET['productid'])) $id = $_GET['productid'] ?>
