grouping and adding form values

[Number7]

Hi, I would like to know if there's a way to quickly collect and sort form data, then use that data in an if statement. I've tried for a while now and i just can't seem to figure it out.

 

 

 

I would like to do this with radio buttons. Hopefully this will make it clear:

Code:

<?php

if (isset($_POST['submit'])) 
{
// I don't know how to do this but maybe something like

// if $_POST values == "Yes"
// put them into an array
// then count how many are in the array, e.g. 2 if 2 "Yes" radio buttons are selected

$count = count($array) . " Yes values selected";
echo $count;

//else if do the same for "No" values

// hopefully this is understandable
}

?>

<!-- i want to take these values and group them, so all the "Yes" values selected together and the "no" values together -->
<form method="post" action="">

<input type="radio" name="first" value="Yes" /> 
<input type="radio" name="first" value="No" /> 

<input type="radio" name="second" value="Yes" /> 
<input type="radio" name="second" value="No" /> 

<input type="submit" name="submit">
</form>

//determine the poss radio buttons
$arrayOfPossibleRadios = array('first','second','third','fourth');

$yesCounter = 0;
foreach($_POST as $key => $value)
{
  if(in_array($key,$arrayOfPossibleRadios))
    {
      if($value == 'yes')
       {
            ++$yesCounter;
       }
    }
}

echo $yesCounter;

Here is an example that I threw together:

<?PHP

  //### Set-up the array of check boxes
  $checkBoxes = array('first','second','third','forth');

  //### Check if the page was requested by post, if so process incoming data
  if($_SERVER['REQUEST_METHOD'] == 'POST') {
  
    //### Initialize the array for "yes" and "no"
    $yesArray = array();
    $noArray  = array();
    
    //### If $_POST['radio'] is set, use it, if not, initialize empty array
    $radiosChecked = isSet($_POST['radio']) ? $_POST['radio'] : array() ;
  
    //### Itterate through each radio button and assign it to the correct array
    foreach($radiosChecked AS $name => $value) {
      if($value) {
        $yesArray[] = $name;
      } else {
        $noArray[] = $name;
      }
    }
    
    //### Echo out the 2 arrays
    echo '<pre>';
    echo '<u>Selected Yes</u><br>';
    print_r($yesArray);
    echo '<br><u>Selected No</u><br>';
    print_r($noArray);
    echo '</pre>';
  
  }
  
?>

  <form method="POST" action="">
<?PHP

  foreach($checkBoxes AS $name) {
    echo $name.'<br>';
    echo '  <input type="radio" name="radio['.$name.']" value="1"> Yes <br>';
    echo '  <input type="radio" name="radio['.$name.']" value="0"> No <br><br>';
  }
?>
    <input type="submit" value="Submit Form">
  </form>

 

Hopefully this will guide you along the way to finding a correct solution to your problem

Thanks a lot for the replies it reeeally helped. I ended up doing something like this in case anyone wants to know (added a bit in case it helps others):

 

<?php
if (isset($_POST['submit']))    
{
$radios = array ($_POST['first'], $_POST['second'], $_POST['third']);
$yesCounter = 0;
$noCounter = 0;
$maybeCounter = 0;
    foreach($radios as $key => $value)
    {
        if ($value == "Yes"){
            ++$yesCounter;
        }
        else if ($value == "No"){
            ++$noCounter;
        }
        else if ($value == "Maybe"){
            ++$maybeCounter;
        }
    }echo $yesCounter, " Yes <br>", $noCounter, " No <br>", $maybeCounter, " Maybe <br>";
}
?>

<form method="post" action="">

<input type="radio" name="first" value="Yes" /><br>
<input type="radio" name="first" value="No" /> <br>
<input type="radio" name="first" value="Maybe" /> <br><br>


<input type="radio" name="second" value="Yes" /> <br>
<input type="radio" name="second" value="No" /> <br>
<input type="radio" name="second" value="Maybe" /> <br><br>

<input type="radio" name="third" value="Yes" /> <br>
<input type="radio" name="third" value="No" /> <br>
<input type="radio" name="third" value="Maybe" /> <br><br>

<input type="submit" name="submit">
</form>

Glad you got something worked out, just a little note though...

 

Try not to rely on the submit button name and value being sent, as not all browsers send that information along with the form.

In my example I used this:

if($_SERVER['REQUEST_METHOD'] == 'POST') {

 

You should try using that, or if there are multiple forms, use a hidden field like this:

<input type="hidden" name="action" value="ACTION VALUE HERE">
