[SOLVED] help with function

[shage]

function createThumbs( $pathToImages, $pathToThumbs)
{
  $dir = opendir( $pathToImages );
echo "<b>Creating Thumbnails</b> <br />";
  while (false !== ($fname = readdir( $dir ))) {
    $info = pathinfo($pathToImages . $fname);
    if ( strtolower($info['extension']) == 'jpg' )
    {
      echo "Creating thumbnail for <b>{$fname}</b> <br />";

$width = 150;
$height = 150;
$dimensions = getimagesize("{$fname}");
$canvas = imagecreatetruecolor($width,$height);
$piece = imagecreatefromjpeg("{$fname}");
$newwidth = $dimensions[0] / 2;
$newheight = $dimensions[1] / 2;
$cropLeft = ($newwidth/2) - ($width/2);
$cropHeight = ($newheight/2) - ($height/2);
imagecopyresized($canvas, $piece, 0,0, $cropLeft, $cropHeight, $width, $height, $newwidth, $newheight);
unset($piece);
if (imagejpeg($canvas,"{$pathToThumbs}{$fname}",90)) 
{
echo 'Image crop successful<br />';
} else {
echo 'Image crop failed<br />';
}
    }
  }
    unset($piece);
  closedir( $dir );
}
createThumbs("imagecreation/","imagecreation/images/thumbnails/");

 

 

when script runs it outputs

 

Creating thumbnail for Vicky07.jpg

 

Warning: getimagesize(Vicky07.jpg) [function.getimagesize]: failed to open stream: No such file or directory

 

file is there, chmod is right, and hell its getting the filename so it must be a real file or directory

As far as i can see $fname should be undefined. Yet, from the output you get, it is, evidently, defined. Are you sure this is the script you are running?

prob in code above let me copy it

[shage]

idea was to open folder and make thumbs from it, since i unload my camera weekly and cropping thumbs by hand sucks, esp now that i have a million christmas pics to upload

You need to specify the path to the file, not just the file:

<?php
function createThumbs( $pathToImages, $pathToThumbs)
{
  $dir = opendir( $pathToImages );
echo "<b>Creating Thumbnails</b> <br />";
  while (false !== ($fname = readdir( $dir ))) {
    $info = pathinfo($pathToImages . $fname);
    if ( strtolower($info['extension']) == 'jpg' )
    {
      echo "Creating thumbnail for <b>{$fname}</b> <br />";

$width = 150;
$height = 150;
$dimensions = getimagesize($pathToImages . $fname);
$canvas = imagecreatetruecolor($width,$height);
$piece = imagecreatefromjpeg($pathToImages . $fname);
$newwidth = $dimensions[0] / 2;
$newheight = $dimensions[1] / 2;
$cropLeft = ($newwidth/2) - ($width/2);
$cropHeight = ($newheight/2) - ($height/2);
imagecopyresized($canvas, $piece, 0,0, $cropLeft, $cropHeight, $width, $height, $newwidth, $newheight);
unset($piece);
if (imagejpeg($canvas, $pathToThumbs . $fname,90)) 
{
echo 'Image crop successful<br />';
} else {
echo 'Image crop failed<br />';
}
    }
  }
    unset($piece);
  closedir( $dir );
}
createThumbs("imagecreation/","imagecreation/images/thumbnails/");
?>

 

Since you're doing this for pictures uploaded from a camera, you might want to check to see if the original images have thumbnails stored with them. Take a look at the exif_thumbnail() function.
