form redirect based on two specific radio buttons selected

[dknoll]

I need help with the php coding for my form. Right now I have a redirect that takes place upon submission of the form and clients are all directed to a payment page (directory_payment.html). The form code that I believe achieves that for me right now is:
<form action="/insert.php" method="post">
<input type="hidden" name="good_url"
value="http://www.mdna.com/directory_payment.html" />

However, in my directory entry form I have several additional options as radio and checkbox buttons.

For example:
LOGO AND ADVERTISEMENT PLACEMENT ORDERS (optional)
Logo Placement:
<td>
Yes <input type="radio" name="logo" value="Yes Logo" />
No <input type="radio" name="logo" value="No Logo" />
</td>
</tr>
<tr>
<td>If you requested Logo Placement, indicate submission option:
</td>
<td>
<input type="checkbox" name="logoemail" value="Will email the Logo" />Email the print material to [e-mail]
<br />
<input type="checkbox" name="logosend" value="Will send the Logo" />
</td>
</tr>
<tr>
Advertising Placement
<td>
Yes - 1/2 Page Ad <input type="radio" name="ad" value="Yes, Half Ad" />
<br />
Yes - 1/1 Page Ad <input type="radio" name="ad" value="Yes, Full Ad" />
<br />
No <input type="radio" name="ad" value="No Ad" />
</td>
</tr>
<tr>
If you requested Ad Placement, indicate submission option:
<td>
<input type="checkbox" name="ademail" value="Will Email Ad" />Email the print material to [e-mail]
<br />
<input type="checkbox" name="adsend" value="Will Send Ad" />
</td>
</tr>

<tr>
    <td style="width: 433px"><input type="submit" value="Submit" /></td>
    <td style="text-align:right;">&nbsp;</td>

I want to create the coding, where if the client chooses BOTH "No" radio options (ie NO Logo AND NO Ad), they should be sent to a "thankyou.html" instead of a payment page which is not relevant to them. However, if they choose Yes to Logo and/or Ad, then they should be sent to the payment page.

Any ideas?

This is not really a question of coing, but more oF logic. I think by just pointing you to if / else you should be able to work it out yourself. Grab a piece of paper and work out the logic. The coding is not complex; Working out the logic is.

Thanks leatherback. I understand that logical operators should do the trick. I am just a newbie here and am not exactly sure how to formulate it for my form options. Also, I am not sure how it works with the current redirect I have set at the beginning of my form code. So I am still stumped a bit....:queasy:

You access the contents of post data through the $POST array, having the form elements' attribute name values as array keys, i.e. $POST['ad'] and $_POST['logo']

if ($_POST['ad'] == 'Yes' && $_POST['logo'] == 'Yes'])
{
    # both ad and logo set to yes
}
elseif ($_POST['ad'] == 'Yes' && $_POST['logo'] != 'Yes'])
{
    # only ad set to yes
}
# etc
