php, get data from HTML select options, store them in variables and perform something

Question

first, i've got a select option in a HTML document

<form action="Journey.php" method="post">
<select name = "Startpoint">
<optgroup label = "Start point">
<option value = "GrimesDyke">GrimesDyke</option>
<option value = "SeacroftRingRoad">SeacroftRingRoad</option>
<option value = "WykeBeck">WykeBeck</option>
<option value = "FfordeGrene">FfordeGrene</option>
<option value = "St.JamesHospital">St.JamesHospital</option>
.........

i determine the action is to pass the data using post method to Journey.php file in order to perform some algorithm, but when i click on the submit button in the browser it shown me my entire php code.... so i decided to run a few tests like this:

Journey.php
<?php
if(isset($_POST['submit'])){
$selected = $_POST['Startpoint'];  // Storing Selected Value In Variable
echo "You have selected :" .$selected;  // Displaying Selected Value
}
?>

this time, it displayed nothing, what i'm trying to do is, to store the Startpoint's value passed to the php file in a $selected variable and echo it on the screen, but it's still not working

i checked many examples online but honestly i can't see what i did wrong, please point out my mistake and show me how exactly i can make it right, thank you very much.

First, please post the HTML of the submit button. It should have < input type.... name = "submit" /> Second, you could try print_r($_POST) in Journey.php and see the list of all POST data, also whether you're getting 'Startpoint' there. — Indrasis Datta

I wrote on php long time ago, but as I remember there is no 'submit' key in the $_POST table. Try to check for 'Startpoint' key instead.

This works for me:

<?php
if(isset($_POST['submit'])){
$selected = $_POST['startpoint'];  // Storing Selected Value In Variable
echo "You have selected: " . $selected;  // Displaying Selected Value
};
?>

<form action="" method="post">
<select name = "startpoint">
<optgroup label = "Start point">
<option value = "GrimesDyke">GrimesDyke</option>
<option value = "SeacroftRingRoad">SeacroftRingRoad</option>
<option value = "WykeBeck">WykeBeck</option>
<option value = "FfordeGrene">FfordeGrene</option>
<option value = "St.JamesHospital">St.JamesHospital</option>
<input type="submit" name="submit" value="Submit">
</form>
