I have a problem that my href does not recognize the link coming from the database.

For example if I put www.facebook.com in the database, when I call it inside the href he brings me href="localhost/projeto/www.facebook.com", but if I take the facebook link https://www.facebook.com/ and put in the database when I call on href he returns to me like this href="https://www.facebook.com/" In other words, it returns the correct link. someone knows what I have to do to href recognize www.facebook.com as a link?

    I think your problem is the lack of protocol http://, https:// in front of the link probably your link this way <a href='facebook.com'> should be <a href='https://facebook.com'>

  • then but then and that’s not me who will manage it I have no way of knowing if the person who will administer will use the protocol, why it would be simple to just put the https:// before the content she types.

    It is up to the programmer to process the data sent via input and to define if what the user typed is correct! the problem is probably what @Icaromartins mentioned, I would try to treat this input to not let you save the url without http!

  • I think it would be good for you to treat this on the server side by checking whether the user will type http or not when saving.

  • Knowing that it will be a link, in reading the data (before putting the a href) Voce can remove the http:// or https:// and put only the // as in the example <a href="//facebook.com"> if I’m not mistaken this should work for a href also, it will automatically select the protocol based on the current page

  • understood did not know that only the // worked I always thought I should specify.

Ideal and you treat before you insert in your database, however if you know that it will always be an external link you can remove the http:// and https:// when you have, and use the // as shown in the example below. It will behave automatically based on the current page, ie if you are on the protocol http:// he’s gonna use http:// if Voce is under protocol https:// he will use https://.

<a href='//facebook.com' target='_blank'>Facebook</a>

Possible problem: If Voce is up the protocol https:// it may be that the destination page does not have this implemented.

Another solution and you always remove http:// and https:// and put by default the http://.

  • if it is not only with external link this is not right either?

  • Only if the link has the dominio example //meusite.com/pagina2.html
