Getting All $_POST From Multiple Select Value

Question

I have this HTML code :

<select name="cars">
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="opel">Opel</option>
  <option value="audi">Audi</option>
</select>

and to make user able to select more than one items, I'm using this jQuery plugin : http://harvesthq.github.com/chosen/

but, once it submitted... the PHP script only able to retrieve one of $_POST['cars'] value. the last one. how to make PHP to be able to retrieve ALL of it?

That's how selects work. unless you add the `multiple` attribute, only a single option is EVER submitted. — Marc B, Oct 28 '12 at 16:37
Supposing that jQuery *is* sending all the values, you still need to specify that `cars` is an array, by naming it `cars[]`. — LSerni, Oct 28 '12 at 16:40

I've found the answer...

<select name="cars[]" multiple="multiple">
  <option value="volvo">Volvo</option>
  <option value="saab">Saab</option>
  <option value="opel">Opel</option>
  <option value="audi">Audi</option>
</select>

and in the PHP part :

$cars = $_POST['cars'];
print_r ($cars);

Just to clarify. In HTML, you need to make sure the name attribute is an array, which you do by adding `[]` at the end of the name. As this example shows. – Joshua Pack Apr 09 '15 at 20:48

Just to clarify even more. This is a PHP trick that has nothing to do with the HTML/DOM spec. – dotnetCarpenter Jan 10 '17 at 20:10

you must do the following:

//$_POST or $_GET is the method of your form request

foreach ($_POST['cars'] as $selected_option) {
    echo $selected_option;
}

that's it.
