Remove trailing slash from comment form

Question

I need code to remove the trailing slash when a user enters their link. For example I need them to put their url to grab their avatar, but in some cases they put their url ending with a slash (.com/). How can I remove that slash automatically? Because when they put their url like that, the avatar doesn't show.

I was looking to remove a trailing slash with php code, but any solution will be appreciated.

I tried to use this code but didn't work:

$string = rtrim($string, '/');

i tried to put a comment on my website, ending with (.com/) and the code didn't remove the slash, therefore the avatar didn't show. — Gio luna, Jun 21 '12 at 03:06
Can you paste a five-line program that reproduces the problem? — sarnold, Jun 21 '12 at 03:06
static function getProfileImage($screenname, $size = 128) { $url = self::API_URL . $screenname . '/avatar/' . $size; — Gio luna, Jun 21 '12 at 03:09
if they add another slash at the end of their website, the avatar won't show because the url it's gonna be like this .com//avatar — Gio luna, Jun 21 '12 at 03:10
For what URL's does your code not work? It works for me: http://codepad.viper-7.com/hvVvLM — Bailey Parker, Jun 21 '12 at 03:35
@SergioVargott Then the URL will be invalid. You should have the user fix it instead of assuming what they meant. — Bailey Parker, Jun 21 '12 at 03:37

Use substring(-1). If it equals "/", then remove it

if (substr($urlString, -1) == "/") $urlString = substr($urlString, 0, -1);

Just before you store the URL. – RandomDuck.NET Jun 21 '12 at 03:12

The function rtrim just removes whitespace form the end of the string. You should check if the last character in the string is a "/" and then remove it if it is.

One way to do this would be:

if (substr_compare($string, "/", -1) == 0) { 
    $string = substr($string, 0, -1);
}

i'm having the same issue, should i put it in the plug in? or in the text box? this is the plug in.. static function getProfileImage($screenname, $size = 128) { $url = self::API_URL . $screenname . '/avatar/' . $size; – Gio luna Jun 21 '12 at 03:23
and the text box is another page – Gio luna Jun 21 '12 at 03:25
Incorrect. `rtrim()` accepts a second option argument `$charList` that takes a string of chars that it should trim from the right of the string along with whitespace. – Bailey Parker Jun 21 '12 at 03:32
