Generate thumbnails of images after uploading

[jaxdevil]

Ok, my code below is not working for generating thumbnail images. The script uploads the files, creates the 'thumbs' directory, but the thumbnails are not created. Where did I go wrong?

 

<?php mkdir("../ebay/$ebay_task/thumbs", 0777); ?>

<?php
$path1= "$ebay_task/".$HTTP_POST_FILES['ufile']['name'][0];
$path2= "$ebay_task/".$HTTP_POST_FILES['ufile']['name'][1];
$path3= "$ebay_task/".$HTTP_POST_FILES['ufile']['name'][2];

copy($HTTP_POST_FILES['ufile']['tmp_name'][0], $path1);
copy($HTTP_POST_FILES['ufile']['tmp_name'][1], $path2);
copy($HTTP_POST_FILES['ufile']['tmp_name'][2], $path3);

echo "File Name :".$HTTP_POST_FILES['ufile']['name'][0]."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size'][0]."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type'][0]."<BR/>";
echo "<img src=\"$path1\" width=\"150\" height=\"150\">";
echo "<P>";

echo "File Name :".$HTTP_POST_FILES['ufile']['name'][1]."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size'][1]."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type'][1]."<BR/>";
echo "<img src=\"$path2\" width=\"150\" height=\"150\">";
echo "<P>";

echo "File Name :".$HTTP_POST_FILES['ufile']['name'][2]."<BR/>";
echo "File Size :".$HTTP_POST_FILES['ufile']['size'][2]."<BR/>";
echo "File Type :".$HTTP_POST_FILES['ufile']['type'][2]."<BR/>";
echo "<img src=\"$path3\" width=\"150\" height=\"150\">";

$filesize1=$HTTP_POST_FILES['ufile']['size'][0];
$filesize2=$HTTP_POST_FILES['ufile']['size'][1];
$filesize3=$HTTP_POST_FILES['ufile']['size'][2];

if($filesize1 && $filesize2 && $filesize3 != 0)
{
echo "Images Uploaded Successfully";
}

else {
echo "ERROR.....";
}

//////////////////////////////////////////////

}

}

<?php
function createThumbs( $pathToImages, $pathToThumbs, $thumbWidth )
{
  // open the directory
  $dir = opendir( $pathToImages );

  // loop through it, looking for any/all JPG files:
  while (false !== ($fname = readdir( $dir ))) {
    // parse path for the extension
    $info = pathinfo($pathToImages . $fname);
    // continue only if this is a JPEG image
    if ( strtolower($info['extension']) == 'jpg' )
    {
      echo "Creating thumbnail for {$fname} <br />";

      // load image and get image size
      $img = imagecreatefromjpeg( "{$pathToImages}{$fname}" );
      $width = imagesx( $img );
      $height = imagesy( $img );

      // calculate thumbnail size
      $new_width = $thumbWidth;
      $new_height = floor( $height * ( $thumbWidth / $width ) );

      // create a new temporary image
      $tmp_img = imagecreatetruecolor( $new_width, $new_height );

      // copy and resize old image into new image
      imagecopyresized( $tmp_img, $img, 0, 0, 0, 0, $new_width, $new_height, $width, $height );

Thanks, but I want to keep the original image and create the thumbnail in a new directory. I don't want to resize the image, and I can't draw the image dynamically I need to generate it at the same time of upload on the same page. Any other ideas? I appreciate the help.

You could just save it instead of outputting it.

[jaxdevil]

But I am also doing three at once. The code I have above would resize all the images in that folder, and I will not know there filenames to put into the script. Any ideas?

 

Thanks,

SK

[craygo]

So if I am reading correctly. You are uploading images, you want to save the image as it is into a directory, then create a thumbnail of each image uploaded in another directory. Correct??

[jaxdevil]

Yes, thats exactly what i am trying to do. it doesn't necessarily 'have' to be in another directory, I can even use it appended with a tn_ or something on the filename in the same directory. Any idea?

 

Thanks a ton,

SK

Well I don't want to go messing with your code bu the script I wrote will work fine with a little fix

 

<?php

$size_limit = "yes";                                          //do you want a size limit yes or no.
$limit_size = "2097152";                                       //How big do you want size limit to be in bytes
$limit_ext = "yes";                                           //do you want to limit the extensions of files uploaded
