Question

I’m trying to have a form that when you select the radio button it will select the image and query into the server; now I’m not quite sure as to how this would be accomplished because when I select any other then the original it doesn’t seem to work.
My form Code (Well. The important part)

<form action="update_image.php" method="post">
<input type="hidden" name="page" value="Index" />
<td><center><input name="image" type="radio" value="images/cartoon/2ofus.png" /></center></td>
<td><center><input name="image" type="radio" value="img src='images/cartoon/3lb_Bruce.png" /></center></td>
<td><center><input name="image" type="radio" value="img src='images/cartoon/bearry.png" /></center></td>
<td><center><input name="image" type="radio" value="img src='images/cartoon/Bemmer.png" /></center></td>
<input type="submit" value="Update" />
   </form>

My Query is as follows:

$link     = mysqli_connect("$server", "$user", "$pass", "$webdb");
    $page = mysqli_real_escape_string($link, (string) $_POST['page']);
    $content = mysqli_real_escape_string($link, (string) $_POST['image']);
$query = "UPDATE `pages` 
              SET `image`='<$image>' 
              WHERE `name`='$page'";

    mysqli_query($link, $query);
    mysqli_close($link);

?>

It’s not the best in the world, but overall I think it should work solidly, but it doesn’t, so if anyone might know why it’d be great. Thanks.

The first Is the original. Sorry for not specifying.

This is what I understood from your question. You have a specific image in the home page, whose src is queried from the database and can be updated by the form given by you.

Change the form to :

 <form action="update_image.php" method="post">
      <input type="hidden" name="page" value="Index" />
  <td><center><input name="image" type="radio" value="images/cartoon/2ofus.png" /></center>   </td>
  <td><center><input name="image" type="radio" value="images/cartoon/3lb_Bruce.png" /></center></td>
  <td><center><input name="image" type="radio" value="images/cartoon/bearry.png" /></center></td>
 <td><center><input name="image" type="radio" value="images/cartoon/Bemmer.png" /></center></td>
 <input type="submit" value="Update" />

Change the query to:

  $query = "UPDATE `pages` 
          SET `image`='$image' 
          WHERE `name`='$page'";

In the index page, after querying the tables pages, use the result in the image tag like :

 print "<img src='{$row['image']}'/>";
