Topic: [SOLVED] colour selection problem

[Accurax]

I have a script that allows a user to selecta  phrase, a font, and a colour of that font and see it previewed in a window below the form.

I cant seemt o gett he colour selection to work at all, at the moment it just keeps showing up in red.

heres the script

First the form

Code: [Select]

      <form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<h2>Enter Your Phrase</h2>
  <input type="text" name="phrase" value="<?php 
 if(isset($_POST["phrase"])) {
 echo $_POST["phrase"];
 }  
 ?>"/>


         <br />
<h2>Select Your Font</h2>
<select name="font">
<option value="fonts/Adorable.ttf">Adorable</option>
<option value="fonts/angelina.TTF">angelina</option>
<option value="fonts/Ashley.ttf">Ashley</option>
    </select><br />

<h2>Select Your Color</h2>
<select name="colour">
<option value="red" selected="selected" class="red">Red</option>
<option value="pink" class="pink">Pink</option>
<option value="blue" class="blue">Blue</option>
    </select><br />


         <input type="submit" /><br />
      </form>
 
 
<?php
if(isset($_POST["phrase"])) {
 $p = $_POST["phrase"];
 $f = $_POST["font"];
 $c = $_POST['colour'];
 echo "<img src=\"test2.php?phrase=$p&font=$f&colour=$c\" alt=\"\" />";
}
?>

And now the script to create the image

Code: [Select]

<?php


if(isset($_GET['phrase'])) {

// Set the content-type
header("Content-type: image/png");

$phrase = stripslashes($_GET['phrase']);

// Create the image
$im = imagecreatetruecolor(400, 100);

// Create some colors
$colour = $_GET['colour'];
if ($colour = 'red') {
  $col = imagecolorallocate($im, 255, 000, 000);
}
elseif ($colour = 'pink') {
  $col = imagecolorallocate($im, 255, 105, 180);
}
elseif ($colour = 'blue') {
  $col = imagecolorallocate($im, 000, 000, 255);
}
else {
  $col = imagecolorallocate($im, 0, 0, 0);
}


$white = imagecolorallocate($im, 255, 255, 255);
$grey = imagecolorallocate($im, 128, 128, 128);
$black = imagecolorallocate($im, 0, 0, 0);

//create a border
imagefilledrectangle($im, 1, 1, 398, 98, $white);

// define the path to the selected font
$font = $_GET['font'];

// Add the text
imagettftext($im, 20, 0, 50, 50, $col, $font, $phrase);

// Using imagepng() results in clearer text compared with imagejpeg()
imagepng($im);
imagedestroy($im);

}
?>

Try changing the first piece of code posted to:

Code: [Select]

<?php
if(isset($_POST)) {
$phrase = $_POST['phrase'];
$font = $_POST['font'];
$colour = $_POST['colour'];
}
?>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">

<h2>Enter Your Phrase</h2>
<input type="text" name="phrase" value="<?php if(isset($phrase)) { echo $phrase; } ?>"/>

<br />

<h2>Select Your Font</h2>
<select name="font">
 <option value="fonts/Adorable.ttf">Adorable</option>
 <option value="fonts/angelina.TTF">angelina</option>
 <option value="fonts/Ashley.ttf">Ashley</option>
</select>

<br />

<h2>Select Your Color</h2>
<select name="colour">
 <option value="red" class="red">Red</option>
 <option value="pink" class="pink">Pink</option>
 <option value="blue" class="blue">Blue</option>
</select>

<br />

<input type="submit"/><br />

</form>
 
 
<?php

if(isset($phrase)) {
 $p = $phrase;
 $f = $font;
 $c = $colour;
 echo "<img src=\"test2.php?phrase=$p&font=$f&colour=$c\" alt=\"\" />";
}

?>
