I am working on a form that takes in 5 numbers as INPUT (the number range is from 1 to 10). Then, the OUTPUT will display the 5 numbers entered with their associated color. I am having problems getting the color value to show on the browser. Can someone please help as to what I am doing wrong?

Below is the code I have so far. 

<?php

error_reporting(0);
$position1 = $_POST['p1'];
$position2 = $_POST['p2'];
$position3 = $_POST['p3'];
$position4 = $_POST['p4'];
$position5 = $_POST['p5'];


 if ($_POST['clear'])
{
 $position1="";
 $position2="";
 $position3="";
 $position4="";
 $position5="";
 $message1="";
 $message2="";
 $message3="";
 $message4="";
 $message5="";
}
 if ($_POST['send'])
 

 {
$message1 = "P1:" ."\r\n" .$position1 ."\r\n" .$color1; // to create space we typed in ."\r\n"
$message2 = "P2:" ."\r\n" .$position2 ."\r\n" .$color2;
$message3 = "P3:" ."\r\n" .$position3 ."\r\n" .$color3;
$message4 = "P4:" ."\r\n" .$position4 ."\r\n" .$color4;
$message5 = "P5:" ."\r\n" .$position5 ."\r\n" .$color5;

$color1 = $position1;

  if ($position1 == "2,4,6,8,10")
    echo "Black";
     elseif ($position1 == "1,3,5,7,9")
      echo "Red";
       else
         echo "Number entered is not in game range.";

$color2 = $position2;

  if ($position2 == "2,4,6,8,10")
    echo "Black";
      elseif ($position2 == "1,3,5,7,9")
        echo "Red";
          else
            echo "Number entered is not in game range.";

$color3 = $position3;

   if ($position3 == "2,4,6,8,10")
     echo "Black";
       elseif ($position3 == "1,3,5,7,9")
         echo "Red";
           else
             echo "Number entered is not in game range.";

$color4 = $position4;

    if ($position4 == "2,4,6,8,10")
      echo "Black";
        elseif ($position4 == "1,3,5,7,9")
          echo "Red";
            else
              echo "Number entered is not in game range.";

$color5 = $position5;

    if ($position5 == "2,4,6,8,10")
      echo "Black";
        elseif ($position5 == "1,3,5,7,9")
          echo "Red";
            else
              echo "Number entered is not in game range.";

 }

?>
</div>

   <!-- START :: Input Form -->

It would be easier to read if you used the code icon (<>) and specified PHP. However, as best I can tell there is no place where you set the color in the HTML. I would expect to see "style" tags with the color to be output.

It appears to me that you need to learn more about HTML. Using "\r\n" does not reliably create a new line, you use "<br />" instead. If you want to set a color you need something like <font style="color:red">.

I don't need a break tag, I just need to give the output some spacing.

Also, lets forget about the actual color appearing on the browser. I'm not concerned with that part. I only need help with the PHP code that provides the actual words either "Black" or "Red" to appear beside each number. (Even numbers are BLACK and odd numbers are RED) I can't seem to figure out why it will not work. 🙁

Apparently a space character, or one of the HTML spacing options (&nbsp; &ensp; &emsp;) isn't good enough.

One way 

<?php
$fields = ['p1', 'p2', 'p3', 'p4', 'p5'];
$valid_nums = range(1,10);
$output = '';

if (isset($_GET['p1'])) {
    foreach ($fields as $f) {
        if (!in_array($_GET[$f], $valid_nums)) {
            $clr = 'Not in range';
            $cls = '';
        }
        else {
            if ($_GET[$f]%2 ==0) {
                $clr = 'Black';
                $cls = 'class="even"';
            }
            else {
                $clr = 'Red';
                $cls = 'class="odd"';
            }
        }
        $output .= sprintf("%s <span %s>%2d %s</span><br>", strtoupper($f), $cls, $_GET[$f], $clr);
    }
}
                                                       
?>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Sample</title>
<style type="text/css">
    body  { font-family: verdana,sans-serif; font-size: 12pt; padding: 20px 50px; }
    .even { color: black; font-weight: 600;}
    .odd  { color: red; font-weight: 600;  }
</style>
</head>
<body>
    <?=$output?>
    <hr>
    <form>
        P1 <input type="text" name="p1" size="5"><br>
        P2 <input type="text" name="p2" size="5"><br>
        P3 <input type="text" name="p3" size="5"><br>
        P4 <input type="text" name="p4" size="5"><br>
        P5 <input type="text" name="p5" size="5"><br><br>
        <input type="submit" name="btnSub" value="Submit">
    </form>
</body>
</html>

Sample output:

Sorry, I misunderstood what you are asking. I think your problem is here: 

if ($position1 == "2,4,6,8,10")

Are you expect this to return true/false if $postion1 matches any one of those? That will only return true if $position1 matches that entire string. You need to use in_arry() with one for the even numbers and one for the odd.

Barand.

You are the man. You have outdone yourself again. That's exactly what I was trying to code. Thank you so much. 😁 

Now I need to dive in this code and learn exactly where everything goes and why it works. 

gw1500se your advice is appreciated as well. My head is upside down right now I think I need to take a break and step away from the code for a while before I return to it.
