Do you know how to ask the user name and use? I’m setting up a website that is also a virtual store. I want the store to be nice to whoever comes in, Asking for a name, being nice, saying, "Okay, that item went to your cart, Amanda." But I’d like to know, how do I ask the person’s name, and save it on a cookie? And How can I use the name in the entire site with the cookie? I’ve looked, but just ask the name, and don’t use it. Just welcome. I would like to use the code throughout the site, paying off the user, talking to him. For this, I believe a cookie is needed.

Thank you.

    Hugo, I think what you need is to use Sesssions ($_SESSIONS in php), not cookies. Take a look here: http://blog.thiagobelem.net/learning-a-usar-sessoes-no-php/

  • Interesting comment. But it’s not what I’m looking for. Thank you :)

To save a name to the cookie:

setcookie("nome", "Nome da Pessoa", time()+3600, "/");

To use the cookie:

echo $_COOKIE["nome"];

You can set the time to as much as you want. In the example is about to expire in an hour (3600 seconds).

I don’t see what problem you’re having.

window.String.prototype.novaString=function(de,ate){
    try{
        return this.split(de)[1].split(ate)[0];
    }catch(e){}
    return;
}
if(!document.cookie.novaString("nome=",";")){
    document.cookie="nome="+prompt("Digite seu nome:","");
}
document.getElementById("carrinho").onclick=function(e){
    alert("Pronto, Esse item foi para seu carrinho, "+document.cookie.novaString("nome=",";")+".");
}
<input value="Adicionar ao carrinho" type="button" id="carrinho">

An alternative with Javascript is to use window.sessionStorage or window.localStorage, the explanation for deciding when to use one or the other has already been answered here.

DEMO at Jsfiddle

if(window.sessionStorage){

    if(!sessionStorage.getItem("nome")){
        // Não há um valor definido ainda, então é exibido o prompt para ser inserido o nome.
        // Se o usuário não preenchê-lo, será utilizado o valor "usuário" para referir-se a ele.
        var nome = prompt("Qual o seu nome?") || "usuário";
        sessionStorage.setItem("nome", nome);
    }

    // Há um valor definido, então a mensagem é exibida.
    alert("Olá " + sessionStorage.getItem("nome") + "!");
}

PS: For what you are intending to do, the solution and the link pointed in the comments by rafaels88 is the best choice.
