Question

I have a drop down menu that I want to change to a multiple select box. The code below is working if you only select 1 option (the way I had it before), but of you select 2 it will only show 1 of the two, how can I make it show both options selected, here is the code:

<?php $makes = array("volvo","Saab","Opel","Audi","BMW") ?>


<form method="post" name="store" action="<?php $_SERVER['PHP_SELF'] ?>" >
<select multiple="multiple" name="cars">
<?php foreach ($makes as $make){echo "<option value=\"$make\">". $make ."</option>";           $vehicles = $_POST['cars'];} ?>
    <input name="submit" type="submit">
    </select>
</form>
<?php 


if($_POST['submit']){
  echo $vehicles;
}
?>
</body>
</html>

Answer 1

It isn’t completely clear from your question but I think you mean the following bit of code only echoes one value:

if($_POST['submit']){
  echo $vehicles;
}

To turn your selected cars into an array you need to add [] onto the end of the name:

<select multiple="multiple" name="cars[]">

Then to echo each of the selections you can use a foreach loop:

foreach ($_POST['cars'] as $car)
    echo $car.'<br />';
