Question

When a user fills out this simple radio button form, they need to be shown the link at the bottom only if they a click yes for each and every question. I’m getting some syntax errors when I run this. Noob at PHP!

<form name="myform" action="" method="POST">
<div><br>
<p>Question 1?</p>
<input type="radio" name="group1" value="Yes"> Yes<br>
<input type="radio" name="group1" value="No"> No<br>
<hr>
<p>Question 2?</p>
<input type="radio" name="group2" value="Yes"> Yes<br>
<input type="radio" name="group2" value="No"> No<br>
<hr>
<p>Question 3?</p>
<input type="radio" name="group3" value="Yes"> Yes<br>
<input type="radio" name="group3" value="No"> No<br>
<hr>
<p>Question 4?</p>
<input type="radio" name="group4" value="Yes"> Yes<br>
<input type="radio" name="group4" value="No"> No<br>
<input type="submit"/>
</div>
</form>

<?php
if (isset($_POST['group1']) && isset($_POST['group2']) && isset($_POST['group3']) && isset($_POST['group4'])) {
    if ($_POST['group1']=='Yes' && $_POST['group2']=='Yes') && ($_POST['group3']=='Yes' && ($_POST['group4']=='Yes' print '<div><a href="http://www.mydomain.com/somefile.pdf">grab the file here</a></div>';
}
?>

HTML:

<form name="myform" action="" method="POST">
<div><br>
<p>Question 1?</p>
<input type="radio" name="group1" value="Yes"> Yes<br>
<input type="radio" name="group1" value="No"> No<br>

<input type="radio" name="group3" value="Yes"> Yes<br>
<input type="radio" name="group3" value="No"> No<br>
<hr>
<p>Question 4?</p>
<input type="radio" name="group4" value="Yes"> Yes<br>
<input type="radio" name="group4" value="No"> No<br>
<input type="submit"/>
</div>
</form>
<div id="link">
</div>

JS:

$('input:radio').change(function(){
    if(
        ($('input:radio[name=group1]:checked').val() == 'Yes') &&
        ($('input:radio[name=group2]:checked').val() == 'Yes') &&
        ($('input:radio[name=group3]:checked').val() == 'Yes') &&
        ($('input:radio[name=group4]:checked').val() == 'Yes')
    ){
        document.getElementById('link').innerHTML = '<div><a href="http://www.mydomain.com/somefile.pdf">grab the file here</a></div>';
    }
    else {
        document.getElementById('link').innerHTML = '';
    }

});
