PHP upload a picture

How to upload a picture on a server ?

Here are pieces of script I use to upload a picture on the FICGS server in PHP, of course it is possible to resize, crop the picture & so on (see PHP functions). Feel free to use or change it

First you have to make the form :

<form enctype="multipart/form-data" action="process.php" method="post">
<input type="hidden" name="photo" value="photo" />
<input type="hidden" name="MAX_FILE_SIZE" value="10000000" />
 
<table border="0" width="500" align="center">
  <tr>
    <td width="75">&nbsp;</td>
    <td>upload a photo, JPG format, max. size : 10 Mb<font size="1"><br><br></font>
      <input type="file" size="22" name="photo"> &nbsp; &nbsp; <input type="submit" name="send" value="Send" /></td>
  </tr>
</table>
</form>


Then in process.php you have to check the picture & save it, here I only verify if the picture is square enough then I resize it, copy it & change rights :

if (!empty($_POST['photo']))
{
@unlink($photo_directory.$photo_file);

if (is_uploaded_file($_FILES['photo']['tmp_name']))
{
    $img_size = GetImageSize($_FILES['photo']['tmp_name']);

    if ($img_size[0] / $img_size[1] <= 1.5 AND $img_size[0] / $img_size[1] >= 0.666)
{
    rename($_FILES['photo']['tmp_name'], $photo_directory.$photo_file);

    chmod($photo_directory.$photo_file,0755);

    list($photo_width,$photo_height) = getimagesize($photo_directory.$photo_file);
 
    $photo_resource = imagecreatefromjpeg($photo_directory.$photo_file);

    if ($photo_width > 220) {  $new_height = $photo_height * 220 / $photo_width;  $new_width = 220; }
else  {  $new_height = $photo_height;  $new_width = $photo_width;  }

    $photo_resource_resampled = imagecreatetruecolor($new_width, $new_height);

    imagecopyresampled($photo_resource_resampled, $photo_resource, 0, 0, 0, 0, $new_width, $new_height, $photo_width, $photo_height);
    imagejpeg($photo_resource_resampled,$photo_directory.$photo_file);
}
}
}
