This code shall solve your issue

    <?php

{

    if (isset($_POST['country'])){
        $con = $_POST['country'];

</form>
</body>

You need to select the value inside the list, so that it will display you the result. No selection will have the empty POST['country'] value. — Chris Lim, Feb 27 '14 at 06:03

If the name is an array, it will get all values from a multi-select. – Mike Feb 27 '14 at 03:01
yes he missed the 'name=submit' so the if condition is returning false – ɹɐqʞɐ zoɹǝɟ Feb 27 '14 at 03:03
Ah, gotcha. I thought you were talking about the multiple select. – Mike Feb 27 '14 at 03:03
did it but its throwing error as foolowing: – Vivek Feb 27 '14 at 03:04
its showing: Notice: Undefined index: country in C:\wamp\www\Project_1\Save.php on line 4 – Vivek Feb 27 '14 at 03:06
`print_r($_POST);` is your friend. It doesn't look like you should receive that notice from the code you have. – Mike Feb 27 '14 at 03:07
exactlly i feel the same but it is showing and its driving me nuts. – Vivek Feb 27 '14 at 03:10
do you still have the problem? – ɹɐqʞɐ zoɹǝɟ Feb 27 '14 at 04:07
see the phpfiddle link in my answer,you can get some idea,all the best – ɹɐqʞɐ zoɹǝɟ Feb 27 '14 at 04:13

You don't have a POST index of submit hence your isset() is failing. You are also missing a closing brace for your if statement in your code example. I've modified your example to use the $_POST['country'] for the isset(). This bit worked for me as far as returning selected values goes:

<html>
<head>
</head>
<body>
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
    <select name="country[]" multiple="multiple">
        <option value="Belgium">Belgium</option>
        <option value="France">France</option>
        <option value="Germany">Germany</option>
        <option value="Holland">Holland</option>
        <option value="Greece">Greece</option>
    </select>
    <input type="Submit" value="Submit" />
</form>
</body>
</html>

<?php

    if(isset($_POST['country']))
    {
        $con = $_POST['country'];
        foreach($con as $selected)
        {
            echo 'selected'.$selected;
        }
    }
?>

its not showing any error anymore but still i am unable to echo the listbox elements. – Vivek Feb 27 '14 at 03:25
Are you passing the form submission back into the same page where this test code is running? When I run the code, plus a call to `print_r($_POST['country']` I get the output of `selectedFranceselectedGermanyArray ( [0] => France [1] => Germany )` in my browser window. – Crackertastic Feb 27 '14 at 03:27
yes, html and php code are in the same page. – Vivek Feb 27 '14 at 03:35
Hmmm...odd. Like I said, I get code output from what I have above, so what you see there is doing the job of getting at the countries I select in the list. – Crackertastic Feb 27 '14 at 03:38
