display member image for 24 from date and time member signs up

[cs7536]

I am looking to display a persons image for 24 from the date and time that they initialy sign up on my site. I currently have the script displaying all new members until 12 midnight then it removes all users but I need it to expire individualy based on a 24 hour period instead of all at midnight.

any help would be apprciated

thanks in advance

do you get your image pointers from a database? if so just create another field and put in the unix timestamp of the joining datetime.

$dt = strtotime("now");

then you can use your sql to retrieve only those images that you want

$compare = strtotime("- 24 hours");

$sql  = "select image from imagetable where datejoined > $compare";

if you are not able to use a database but are instead using the filesystem, you may be able to use some of the date information in the filesystem but to make you app cross browser compatible i'd suggest creating a text file into which you programmatically insert each filename and the timestamp and then test against it.

//manage the upload
$fh = fopen ("imagedb.txt", "a+");
fwrite ($fh, $_FILES['uploadedfile']['filename'] . ",".strtotime("now")."\n");
fclose ($fh);

and then to test

$compare = strtotime("- 24 hours");
$newfile ="";
$fh = fopen ("imagedb.txt", "rb");
while (($data = fgetcsv($fh, 2048, ",")) !== FALSE):
   if ($data[1] > $compare):
      $imagestoshow[] = $data[0];
      $newfile .= "{$data[0]},{$data[1]})\n";
   endif;
endwhile;
fclose($fh);
//all the images to show are in $imagestoshow
foreach ($imagestoshow as $fnam):
  echo "<img src=\"$fnam\" /><br/>";
endforeach;
//now scrub the db file and fill it with only the items that are still fresh.
$fh =fopen("imagedb.txt", "wb");
fwrite ($fh, $newfile);
fclose ($fh);
}

p.s. i have not tested the above for errors.
