链接到您的应用程序laravel之外的资源

No one seems to hit this problem, as there no questions on it online.

When i do something like

<a href="{{ $client->client_url }}" class="btn  btn-default">Go back to {{ $client->client_name }} homepage></a>

Laravel istead of taking the user to say

http://www.client_website.com

it does something like

http://myApp/http://www.client_website.com

Any ideas are much appreciated.

You must be saving client_url as full URL. I.e: http://www.client_url.com

So this way it will not append to your url. but rather open client url.

And one suggestion: Add _target="blank" to your <a> tag, this open new tab instead of loading on the same tab and override your own site.

You may try this:

<a
    href="http://www.{{ $client->client_url }}"
    class="btn btn-default"
    target="_blank" <!-- If you want to open the external page in a new tab/window -->
>
    Go back to {{ $client->client_name }} homepage
</a>

Also you can save the full URL (including http://www.) in database when saving it and just use href="{{ $client->client_url }}" as suggested in other answer.
