Adding checked radio buttons - Tilted Forum Project Discussion Community

Lewis · 01-13-2005, 11:44 AM

I hope there is someone out there who can give me a solution to what must be a very simple question, but that has flummoxed me, for some reason.

I'm doing a site with a quiz on it. There are yes and no answers to all question that are indicated by checking radio buttons. I simply want to add all the 'yes' answers that are given, and display the number on a results page.

Can't figure it out. Can anyone suggest the code I could use?

Many thanks.

Well there's a couple solutions available, but they'd use some different languages than just straight HTML.......for instance you could use JavaScript to collect the values of the radio buttons and put them in a cookie that would be passed to the next page, or the simplest would probaby be to use a language like PHP and utilize the html Post or Get methods from a form. the code for this would look something like ::

****************************************************
*************INITIAL PAGE WITH RADIO BUTTONS************
****************************************************
<html>
<head>
<title>First Page</title>
</head>

<body>
<form name="form1" action="display.php" method="post">
<input type="radio" name="one" value="Yes"> <input type="radio" name="one" value="No">
<input type="submit" value="submit>
</form>

</body>
</html>

**************************************************
****************DISPLAY PAGE (PHP)*******************
**************************************************
<html>
<head>
<title>show</title>
<?php
$var1 = $_REQUEST['one'];
?>
</head>

<body>
<br><br><center><?= $var1 ?></center>
</body>
</html>

*******************************************************
**********************END EXAMPLE***********************
*******************************************************

The thing to remember about this one is that the page that is displaying the values has to be a PHP page. You can do this exact same thing in CGI or any wide variety of other languages. The initial page can be straight htm as long as you're using the form tags.

If you want you can use the Get methods (replace POST with GET in the form tag), which puts the values up in the URL, but you're limited in size of how much you can throw up there, and text area's don't work then.

If this doesn't work, just yell at me or something

Forgot this part, sorry. This would actually go in the php code on the display page.........so inside the php code add the following:

$counter = 0;
if($var1 == "Yes"){
$counter = $counter + 1;
}

so the display page would look like ::

******************************************
******************************************
******************************************

<html>
<head>
<title>show</title>
<?php
$var1 = $_REQUEST['one'];
$counter = 0;
if($var1 == "Yes"){
$counter = $counter + 1;
}
?>
</head>

<body>
<br><br><center><?= $var1 ?></center><br><br><center><?= $counter ?></center>
</body>
</html>

Peace::

how about this:

Code:

<?php
$count = 0;
foreach($_POST as $v){
  if($v == 'yes'){
      $count++;
  }
}
<html>
<body>
<?php echo $count; ?> yes answers
</body>
</html>

Blimey! Thanks to both. I'll have a look at it over the weekend.

Sorry if my replies are a bit slow, but I'm probably on a different timescale to you.

You could easily do a JavaScript solution that (when you 'submit') will count the 'yes' options on the page (reading the answers from the DOM) and display it on the screen. No PHP required.

Essentially you want to put all your answers inside a DIV and use some javascript to read in the children of that div and record the values. You can then use innerHTML to write the results back to the page.

If that sounds like a load of gobbledegook let me know and I'll try to help you...

Thanks quannum, that's what I was hoping to do, and I still haven't fixed it yet. What you have to understand is that I am brand new to all this. I tried a couple of the other solutions shown on this thread, and feel bad because I am sure they are great, but it all just go screwed up somehow.

The first one looked good, but only seemed to allow me to check one radio button at a time for the whole questionnaire - as soon as I checked another one for another question, the one on the previous question unchecked. I couldn't figure out the second one, but I don't want to sound ungrateful. In fact, I feel a bit embarrassed that what must appear utterly straightforward to you guys, is not so simple for me.

I think I need an idiot's guide to this.

Cheers.
