If you’re going to use php, and this select is inside a form, you can do so.

<html>
<body>
  <form action="#" method="post">
    <select class="form-control qa-product-options__quantity" name="quantidade" id="quantity">
      <option value="1">1</option>
      <option value="2">2</option>
      <option value="3">3</option>
      <option value="4">4</option>
      <option value="5">5</option>
      <option value="6">6</option>
      <option value="7">7</option>
      <option value="8">8</option>
      <option value="9">9</option>
      <option value="10">10</option>
      <option value="11">11</option>
      <option value="12">12</option>
      <option value="13">13</option>
      <option value="14">14</option>
      <option value="15">15</option>

  • thanks for the help @Rafa worked

  • Tamo together. Success in the project.

  • By the way, can you tell me how to put this into a variable?

  • you mean the $_POST['quantity']; ?

  • yes exactly

  • If you intend to use this variable input from that same file you can do Ex: $quantiade = $_POST['quantity']; - if you are going to send to another page use Session, or send by URL

  • thank you very much :)

If you are using Jquery

$('#quantity').find(":selected")

The pure javascript analogue is

var e = document.getElementById("quantity");
var selected = e.options[e.selectedIndex].value;
