PHP Radio Button Checked Changed after submit

Question

I've beed using this website for quite some time now but I never needed to post anything until now.

I've been a programmer in ASP.NET (C# or VB.NET) but now I'm trying to extent my knowledge to PHP as well.

Well let's get to the point.

I've created a page where the users will be able to buy come packages according to their choice and using PayPal. I've decided to use radio buttons in order to show the user the possibilities he have since all the options are stored in the database.

So I use this to create the RadioButtons:

  <? while($row=mysql_fetch_assoc($result)) { ?>
    <div class="PackagesInfo" style="padding: 10px 10px 10px 200px; font-size:10pt;">
        <span class="PackagesInfo<?=$row['bids_number']?>"></span>
        <p><input type="radio"  name='package_id' value='<?= $row['id'] ?>'>&nbsp;&nbsp;<?= $row['bids_number'] ?><?php echo $MSG_40_024;?><?= print_money($row['price']) ?></input></p>
    </div>
<? } ?>

Then when the user chooses the option he desires and on the onsubmit of the form I do this:

<script>
function fill_price() {
    var package_choosen=0;
    for (var i=0; i<document.getElementById("paypal_frm").package_id.length; i++) {
        if (document.getElementById("paypal_frm").package_id[i].checked) {
            package_choosen=1;
            package_checked=document.getElementById("paypal_frm").package_id[i].value;
        }
    }
    if (package_choosen!=1) {
        alert("Please select a bid package!")
        return false;
    }
    document.getElementById("custom").value +="=="+package_checked;
    document.getElementById("amount").value=prices[package_checked];
}
</script>

But what is happening is that if the users chooses the option number 1 and presses the submit button and after the click he then selects another option, for some reason the second option will be used instead. This doesn't happens all the time, it's quite random actually. I have no clue what may be causing this to happen.

Thanks a lot for your time.

Could you post the actual HTML form as it is output to the client by PHP? — Sébastien, Nov 01 '13 at 21:31
Also since you are starting with PHP, please read: http://stackoverflow.com/questions/12859942/why-shouldnt-i-use-mysql-functions-in-php — Sébastien, Nov 01 '13 at 21:32
@Sébastien working PHP code, open up xammp write ` echo "Hello World" ?>` and you will likely see the code itself (or nothing at all) and not the output `"Hello World"`, replace the opening `` with ` — classicjonesynz, Nov 01 '13 at 21:36
@Killrawr If that is what happened to the OP I think he would have noticed. He probably has shorttags enabled whether he knows it or not. — Sébastien, Nov 01 '13 at 21:39
@Sébastien if the output is blank, or it's hidden in HTML encoding (as you see OP rendering PHP data into HTML attributes), It isn't as easy to notice as you would think. — classicjonesynz, Nov 01 '13 at 21:41
You mean user selects one of the options and then presses the submit and before page's refresh if user select another option it would be the one to send? — MahanGM, Nov 01 '13 at 21:43
