<form method="get" action="index.php">
<select name="choice" size="1" onchange="this.form.submit()">
<option value="a">a</option>
<option value="b">b</option>
<option value="c">C</option>
</select></form>

The code above displays a dropdown menu of options, such as a, b, or c, the user can click on. After the user clicks on a, b, or c from the drop down menu, that option is submitted in the form, and the page reloads with a new $_GET variable “choice” defined as a, b, or c. I want the option that the user last selected to now be the default selected option listed. For example, after the user clicks on “b” from the dropdown menu, “b” shows up as selected on the drop down menu list. What’s the best way to accomplish this?

    Here you go:

    <?php

    if (isset($_REQUEST['choice'])) {

        $selected_choice = $_REQUEST['choice'];

    }
    else {

        $selected_choice = "none";

    }

?>

<html>
<head>
</head>
<body>

<form method="get" action="">
    <select name="choice" size="1" onchange="this.form.submit()">
        <option value="a" <?php if($selected_choice == "a"){ print "selected='selected'"; } ?> >a</option>
        <option value="b" <?php if($selected_choice == "b"){ print "selected='selected'"; } ?> >b</option>
        <option value="c" <?php if($selected_choice == "c"){ print "selected='selected'"; } ?> >C</option>
    </select>
</form>

</body>
</html>
