问题
I want to set external URL in some of my anchor tags but facing problem when URL is without http/https protocol. When URL is without these protocols URL become like following:
<a target="_blank" href="www.usatoday.com/"></a>
when I click on it or hover over it, it shows and redirect me to: http://localhost/event/www.usatoday.com
I've tried following two ways in href but didn't worked:
{{url($eventSponsorsRow->sponsorUrl)}}
{{ $eventSponsorsRow->sponsorUrl }}
instead of URL in href. Laravel 5.3
回答1:
This is HTML and browser stuff, not Laravel/PHP itself.
You just need to provide protocol part of the url to make it external.
You can skip the http: but it needs at least double slash in front of the url like:
<a target="_blank" href="//www.usatoday.com/"></a>
Please not, that if you skip the http(s): part it will use currently used protocol.

You need to prepend http:// to the url
if you want to use {{url($eventSponsorsRow->sponsorUrl)}} make sure when you insert into a database it prepends http:// with it
<a target="_blank" href="{{ url($eventSponsorsRow->sponsorUrl) }}"></a>
if you don't want to do that you will need to create a variable with the url you are getting from the database and prepend the http://
$newvariable = "http://$eventSponsorsRow->sponsorUrl";
and call the $newvariable in the correct location
<a target="_blank" href="{{ $newvariable }}"></a>
