Dynamic Image too file - help please.

[RyanJones]

Hi everyone!

I have this code:

  class GD_Verification
  {
    var $IM = NULL;
    var $String = NULL;
    var $Height;
    var $Width;

function GD_Verification($Height = 150, $Width = 35, $SID = NULL)
{
  if ($SID != NULL)
  {
      session_name($SID);
  }
  $this->Height = $Height;
  $this->Width  = $Width;
}

function Generate_String()
{
  $this->String          = substr(sha1(mt_rand()), 17, 6);
  $_SESSION['GD_String'] = $this->String;
}

function Verify_String($GD_String)
{
  if ($_SESSION['GD_String'] === $GD_String)
  {
    return true;
  }
  else
  {
    return false;
  }
}

function Create_Input_Box($Name, $Margin)
{
  $Master  = '<label for="' . $Name . '">Validation Code: </label>';
 $Master .= '<input type="text" name="' . $Name . '" id="' . $Name . '" style="margin-left: ' . $Margin . 'px;" />';
  return $Master;
}

function Create_Image()
{
  $this->Generate_String();
  $this->IM = imagecreatetruecolor($this->Height, $this->Width);

  $Image_Width  = imagesx($this->IM);
  $Image_Height = imagesy($this->IM);
  $Black = imagecolorallocate($this->IM      , 0   , 0   , 0);
  $White = imagecolorallocate($this->IM      , 255 , 255 , 255);
  $Red   = imagecolorallocatealpha($this->IM , 255 , 0   , 0   , 75);
  $Green = imagecolorallocatealpha($this->IM , 0   , 255 , 0   , 75);
  $Blue  = imagecolorallocatealpha($this->IM , 0   , 0   , 255 , 75);
  $End   = imagecolorallocatealpha($this->IM , ceil(rand(0, 255)), ceil(rand(0, 255)), ceil(rand(0, 255)), ceil(rand(0, 255)));

  imagefilledrectangle($this->IM, 0, 0, $Image_Width, $Image_Height, $White);

    // Ellipses (helps prevent optical character recognition)
  imagefilledellipse($this->IM, ceil(rand(5, $Image_Width - 5)), ceil(rand(0, $Image_Height)), 30, 30, $Red);
  imagefilledellipse($this->IM, ceil(rand(5, $Image_Width - 5)), ceil(rand(0, $Image_Height)), 30, 30, $Green);
  imagefilledellipse($this->IM, ceil(rand(5, $Image_Width - 5)), ceil(rand(0, $Image_Height)), 30, 30, $Blue);
  imagefilledellipse($this->IM, ceil(rand(5, $Image_Width - 5)), ceil(rand(0, $Image_Height)), 30, 30, $End);

  imagefilledrectangle($this->IM, 0 , 0, $Image_Width, 0, $Black);
  imagefilledrectangle($this->IM, $Image_Width - 1, 0, $Image_Width - 1, $Image_Height - 1, $Black);
  imagefilledrectangle($this->IM, 0, 0, 0, $Image_Height - 1, $Black);
  imagefilledrectangle($this->IM, 0, $Image_Height - 1, $Image_Width, $Image_Height - 1, $Black);

  imagestring ($this->IM, 5, intval(($Image_Width - (strlen($this->String) * 9)) / 2),  intval(($Image_Height - 15) / 2), $this->String, $Black);
}

function Output_Image()
{
  $this->Create_Image();
  header("Content-type: image/jpeg");
  imagejpeg($this->IM);
  imagedestroy($this->IM);
}
  }

Can someone modify that so the image is saved to a temporary file instead of displaying directly?

Cheers,

Simply fopen and fwrite it instead of displaying it.

[_theworks]

just change this...

imagejpeg($this->IM); 

to

imagejpeg($this->IM,'new_file.jpg');

But how exactly?

imagejpeg -- Output image to browser or file

The filename argument is optional, and if left off, the raw image stream will be output directly. To skip the filename argument in order to provide a quality argument just use an empty string (''). By sending an image/jpeg content-type using header(), you can create a PHP script that outputs JPEG images directly.

imagejpeg($this->IM,'new_file.jpg');

Oh, I apologize. I've never really messed around with the image functions, so I didn't know it's args. Go with _theworks' solution, it is far simpler.

Thanks all, that worked perfectly 😃
