Changing Theme

**vividona** · 01-24-2009, 07:41 AM

I have many Themes in my Themes folder. What is the idea of changing theme through database. I mean is it possible to pickup one of theme from database?.

Thank you in advance

Well, the following code isn't exactly for a database but then I don't know why you'd want a database if you're going to be using stylesheets, why not just have them in a folder called "Themes" and then allow the user to select from one of them. Please try and explain how the database will be helpful in this situation.

Anyway, here's a simple style changer:

PHP Code:


<?php
if (isset($_GET['theme']))
    {
    $theme = $_GET['theme'];
        switch ($theme)
        {
        case 1:
            $theme = 1;
            break;
        case 2:
            $theme = 2;
            break;
        case 3:
            $theme = 3;
            break;
        case 4:
            $theme = 4;
            break;
        default:
            $theme = 1;
        }
        
}
?>
<html>
<head>

<link rel="stylesheet" type="text/css" href="theme<?php if(isset($theme)) { echo "$theme";} ?>.css"/>
</head>
<body>

<form action="themes.php" method="get">
<select name="theme">
<option value="1">Theme 1</option>
<option value="2">Theme 2</option>
<option value="3">Theme 3</option>
<option value="4">Theme 4</option>
</select><p></p>
<input type="submit" value="Select"/>
</form>


</body>
</html>

Better:

Code:

<?php
  session_start();

  $themes = array(
    'red' => 'Red',
    'greenish' => 'Green/Blue',
    'transparent' => 'Glass',
    'fish' => 'Sea Life',
    'grass' => 'Natural'
  );

  $defaultTheme = @$_POST['theme'];
  if (!isset($themes[$defaultTheme]))
    $defaultTheme = key($themes);

  $_SESSION['preferred_theme'] = $defaultTheme;
?>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
  <head>
    <link rel="stylesheet"
          type="text/css"
          href="<?php echo $defaultTheme; ?>">
  <?php foreach ($themes as $file => $title): ?>
    <link rel="alternate stylesheet"
          type="text/css"
          href="<?php echo $file; ?>.css"
          title="<?php echo $title; ?>">
  <?php endforeach; ?>
  </head>
  <body>
    <form action="<?php echo $_SERVER['REQUEST_URI']; ?>">
      <div>
        <select name="theme">
        <?php foreach ($themes as $file => $title): ?>
          <option value="<?php echo $file; ?>">
            <?php echo $title; ?>
          </option>
        <?php endforeach; ?>
        </select>

        <input type="submit" value="Select">
      </div>
    </form>
  </body>
</html>

Schmoopy, watch that pseudo-XHTML.
