Issue Summary

Link for reseting user password doesn't have schema, it starts with //

Example:

If this was sent in error, you can ignore this message.

To reset your password, visit this address: //localhost:8000/admin/login/reset/?username=USER&token=84325b15d6dbaf881a594c41654405e7786d8c8726c40abe5484fdecd5564097e40d0e51ea0f4794ac82deff1a1624da9545

It makes it unusable as a proper link.

1. Go to login page
2. Click on recover my password
3. Put your user name and click Continue

This was broken in c9a3c0a. I'll see what I can come up with for a proper solution.

If we want to send an email, we call Postleaf::url(true).

public static function url($withProtocol = false) {
        $protocol = empty($_SERVER['HTTPS']) ? 'http' : 'https';
        // Get the hostname
        $hostname = $_SERVER['HTTP_HOST'];
        // Determine if Postleaf is running from a subfolder
        $subfolder = self::subfolder();
        // Get args and prepend subfolder
        $args = func_get_args();
        array_unshift($args, $subfolder);
        // Remove empties
        $args = array_filter($args, 'mb_strlen');
        // Glue them together
        $path = implode('/', $args);
        // Convert backslashes to forward slashes
        $path = str_replace('\\', '/', $path);
        // Remove duplicate slashes
        $path = preg_replace('/\/+/', '/', $path);
        // Remove preceding slash
        $path = ltrim($path, '/');
        // Generate the URL
        return ($withProtocol) ? "$protocol://$hostname/$path" : "//$hostname/$path";
    }

That will reintroduce the same issue we saw with #57. It also doesn't account for the other URL functions that are wrappers for Postleaf::url().

[Cory LaViska]

Protocols have been added back to the URL generator, along with a new method to detect SSL.

The old SSL check seemed to work for 99% of environments, and adding the isSsl() method will make it easier to adjust for edge cases.
