Pixel Image not logged, Basic conversion tracking

[dflow]

I have the following  <img> on  a completed.php after  a signup.php

<img src="http://example.com/pixelimage.php?AffID=98798" width="1" height="1">

the pixel is generated here pixelimage.php

<?php

  // Create an image, 1x1 pixel in size
  $im=imagecreate(1,1);

  // Set the background colour
  $white=imagecolorallocate($im,255,255,255);

  // Allocate the background colour
  imagesetpixel($im,1,1,$white);

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

  // Create a JPEG file from the image
  imagejpeg($im);

  // Free memory associated with the image
  imagedestroy($im);


 if (isset($_GET['AffID'])) {
  

//   $query_add="UPDATE auth_table SET etat = replace(etat,'$anc','$nv') where user_id LIKE  
// '%$log%'";
// $query_exec=mysql_query($query_add) or die(mysql_error()); 

// <script language='JavaScript'>alert('Activation termine')</script>
echo $AffID = $_GET['AffID'];
$date = date("Y-d-m"); 
$hour = date("H:i"); 
$op=$date.$hour.'Affiliate ID : '.$AffID;
$op .= "\n";
$file = 'log.txt';
$search = file_get_contents($file);
$check = strpos($search, $log);
if ($check === FALSE) {
  $fp = @fopen($file, 'a');
  $write = @fputs($fp, $op);
  @fclose($fp);
}

 }
?>

the image is generated but the action does not get logged.

 

I can only get it logged  when I reload the completed.php page.

 

what did I mess up?

i don't think it's the only problem but one thing I see is that $log is not defined when you are using it in your strpos

how else can I test the img firing back?

[.josh]

well what I'm saying is

 

$check = strpos($search, $log);

 

you don't define $log anywhere.

you don't define $log anywhere.

even with $log defined It isn't logged via the remote page.

Remove the error suppression ( the @) from in front of the fopen, fwrite and fclose functions and turn error reporting on. They could be returning an error when trying to write to the log. If an error occurs then nothing will be written to the log.

 

Also what is the purpose of    $check = strpos($search, $log);

I used a quick script I found, I removed the $check and still I the <img> is not logged and no errors, the log works when I reload pixelimage.php
