Make a Radio Button Selected by PHP Session

[johnwboyd]

On the product pages we have a code like this:

<select name="paymentmethod1" id="paymentmethod1">
<option value="MoneyPak">MoneyPak</option>
</select>


<select name="paymentmethod2" id="paymentmethod2">
<option value="MoneyPak">MoneyPak</option>
</select

etc.

Through Session it writes to the order checkout form header as text such as MoneyPak or Credit Card through the code:

<?php echo($_SESSION["paymentmethod".$counter]); ?>

Now what I am trying to do here is get the user selection of Credit Card or MoneyPak radio button from the product page to automatically trigger the corresponding radio button to be checked:

 <input name="1" type="radio" class="radio2" id="creditcard" style="padding-left:0px" 
onclick="showhide('creditcardxx', 'block'); showhide('m-p-kx', 'none'); 
showhide('splitx', 'none'); showhide('charge', 'block'); showhide('option3m', 'none'); 
showhide('option3', 'none'); showhide('option2', 'block')" value="creditcard"/>

I was thinking it could be something like this maybe but I can't get it to work:

<input name="1" <?php if (echo($_SESSION["paymentmethod".$counter])=='MoneyPak') {
echo checked="checked" ;} ?> type="radio" class="radio" id="MoneyPak" 
onclick="showhide('m-p-kx', 'block'); showhide('splitx', 'none'); 
showhide('creditcardxx', 'none'); showhide('paypalx', 'none'); showhide('charge', 
'none'); showhide('option3', 'none'); showhide('option3m', 'none'); showhide('option2', 
'none');" value="MoneyPak">

I also don't know if I should have else in both radio buttons or not.

Maybe
<input type="radio" name="whatever" value="whatever" <?php if(isset(session) && session == whatever_value){echo checked="checked";} ?> />
or something like that
