Question

I have a html form with grouped radio button. This form contains questions with yes or no options
<form action="results.php" method="post" enctype="multipart/form-data"><br>
<p>Have you ever turned a client down?</p>
<div id="q_1">
<input type="radio" name="q[]" id="q_1_yes" value="yes">
<label for="q_1_yes">Yes</label>
<input type="radio" name="q[]" id="q_1_no" value="no">
<label for="q_1_no">No</label>
</div><br>
<p>Are you comfortable with failure?</p>
<div id="q_1">
<input type="radio" name="q[]" id="q_2_yes" value="yes">
<label for="q_2_yes">Yes</label>
<input type="radio" name="q[]" id="q_2_no" value="no">
<label for="q_2_no">No</label>
</div><br>
<p>Can your concept be easily described and understood?</p>
<div id="q_1">
<input type="radio" name="q[]" id="q_3_yes" value="yes">
<label for="q_3_yes">Yes</label>
<input type="radio" name="q[]" id="q_3_no" value="no">
<label for="q_3_no">No</label>
</div><br>
<input type="submit" name="sub_eit" id="sub_eit" value="Submit">
</div>
</form>
I know i can count the number of radio buttons with name q
$count_cbox = count($_POST['q'])
But is it possible that when the user makes a choice i count the radio button value that ="yes" or "no".

Answer 1

Please change your radio button names slightly. Otherwise the grouping doesn't work:
<form method="post" enctype="multipart/form-data"><br>
<p>Have you ever turned a client down?</p>
<div id="q_1">
<input type="radio" name="q[0]" id="q_1_yes" value="yes">
<label for="q_1_yes">Yes</label>
<input type="radio" name="q[0]" id="q_1_no" value="no">
<label for="q_1_no">No</label>
</div><br>
<p>Are you comfortable with failure?</p>
<div id="q_1">
<input type="radio" name="q[1]" id="q_2_yes" value="yes">
<label for="q_2_yes">Yes</label>
<input type="radio" name="q[1]" id="q_2_no" value="no">
<label for="q_2_no">No</label>
</div><br>
<p>Can your concept be easily described and understood?</p>
<div id="q_1">
<input type="radio" name="q[2]" id="q_3_yes" value="yes">
<label for="q_3_yes">Yes</label>
<input type="radio" name="q[2]" id="q_3_no" value="no">
<label for="q_3_no">No</label>
</div><br>
<input type="submit" name="sub_eit" id="sub_eit" value="Submit">
</div>
</form>
The PHP code:
for($i = 0; $i < count($_POST['q']); ++$i) {
if($_POST['q'][$i] == 'yes') {
++$yes;
}
}
Now $yes contains the number of radio buttons with the value yes. In this case 0-3. Please pay attention to the fact that if no radio button is selected, it will return NULL, not 0.
