If this doesn't work I give up. I tested it on my server, by setting up an exact directory structure as you. Make sure you give write permissions to the thumb, full and upload dirs.

<?php
$uploaddir = \"/home/swimtige/public_html/img/pics/\"; // Path to full image folder

if (move_uploaded_file($_FILES[\"userfile\"][\"tmp_name\"], $uploaddir . $_FILES[\"userfile\"][\"name\"]))

{

// Move the original uploaded file to the pics directory

$picture = $uploaddir . $_FILES[\"userfile\"][\"name\"]; // /home/swimtige/public_html/img/pics/pic.jpg
$picture_name = $_FILES[\"userfile\"][\"name\"]; // pic.jpg
// Set a few variables


$size = getimagesize(\"$picture\");
$width = $size[0];
$height = $size[1]; // Find out the height and width attriutes of image
$newHeight = 100;
$newWidth = 100; // Set the new height and width of thumbnail


$oldimage = ImageCreateFromJPEG(\"$picture\");
$newimage = ImageCreateTrueColor($newWidth,$newHeight);
imagecopyresampled($newimage,$oldimage,0,0,0,0,$newWidth,$newHeight,$width,$height);

ImageJPEG($newimage,\"$picture_name\"); 
// Thumbnail picture is created in /upload/ dir

copy($picture_name, \"/home/swimtige/public_html/img/thumbs/$picture_name\");
// So move it to /thumbnail/ dir

unlink(\"home/swimtige/public_html/upload/$picture_name\"); 
// Delete the useless thumbnail in /upload/ dir

}

else {
echo \"Image upload failed!\";
}
?>

Heres the working code straight from my image gallery script:

<?php
$uploaddir = \"/home/swimtige/public_html/img/thumbs/\";

move_uploaded_file($_FILES[\"userfile\"][\"tmp_name\"], $uploaddir . $_FILES[\"userfile\"][\"name\"])

$picture = $uploaddir . $_FILES[\"userfile\"][\"name\"];
$picture_name = $_FILES[\"userfile\"][\"name\"];

$size=getimagesize(\"$picture\");
$width=$size[0];
$height=$size[1];
$newHeight=100;
$newWidth=100;


$oldImage=ImageCreateFromJPEG(\"$picture\");
$newImage=ImageCreateTrueColor($newWidth,$newHeight);
imagecopyresampled($newImage,$oldImage,0,0,0,0,$newWidth,$newHeight,$width,$height);
ImageJPEG($newImage,\"TN_\".\"$picture_name\");
$picture3=\"TN_$picture_name\";
copy($picture3, \"/home/swimtige/public_html/img/thumbs/$picture3\");
unlink(\"PATH TO THE FOLDER WHICH THE SCRIPT IS IN/$picture3\");
?>

This basically uploads an image, puts it in a folder and creates a thumbnail of it in the same directory. Hopefully it'll work this time..

alright, well i put it in with the upload script, and it doesn't work. (i had to mod it a little bit)...here's the errors i get (i tried to upload mountains.jpg):

Warning: getimagesize: Unable to open 'mountains.jpg' for reading. in /.../do_upload.php on line 86

Warning: imagecreatefromjpeg: Unable to open 'mountains.jpg' for reading in /.../do_upload.php on line 93

Warning: imagecopyresampled(): supplied argument is not a valid Image resource in /.../do_upload.php on line 99

Warning: imagejpeg: unable to open 'mountains.jpg' for writing in /.../do_upload.php on line 100

Warning: Unable to open 'mountains.jpg' for reading: No such file or directory in /.../do_upload.php on line 104

and the php (including the final upload part of my code):

<?php
if ($_FILES['img1'] != \"\") {
    
    copy($_FILES['img1']['tmp_name'], \"$ufolder\".$_FILES['img1']['name']) 
        or die(\"Couldn't copy the file!\");  
    
} else {
    
    die(\"No input file specified\");
}
if ($_FILES['img1'] != \"\") {

    
    $picture = $_FILES[\"img1\"][\"name\"]; // Assign the uploaded file to $picture

    $size = getimagesize(\"$picture\"); // Get the size of the image
    $width = $size[0];
    $height = $size[1];
    $newheight = $newheight / 2; // Halve the height
    $newwidth = $newwidth / 2; // Halve the width


    $oldimage = ImageCreateFromJPEG(\"$picture\");
    // New image will be based on old image (hence \"create from\")

    $newimage = ImageCreateTrueColor($newwidth,$newheight);
    // Create a new JPEG image with new height and width

    imagecopyresampled($newImage,$oldImage,0,0,0,0,$newwidth,$newheight,$width,$height);
    ImageJPEG($newimage,\"$picture\");
    // Old image will be added/pasted onto to the new image
    // Create the image

    copy($picture, \"/home/swimtige/public_html/img/thumbs/\");
    // Copy it to another directory

} else {

    die(\"Could not copy and resize image.\");
}
?>

thanks.

<?php
$picture = $_FILES[\"userfile\"][\"name\"]; // Assign the uploaded file to $picture

$size = getimagesize(\"$picture\"); // Get the size of the image
$width = $size[0];
$height = $size[1];
$newheight = $newheight / 2; // Halve the height
$newwidth = $newwidth / 2; // Halve the width


$oldimage = ImageCreateFromJPEG(\"$picture\");
// New image will be based on old image (hence \"create from\")

$newimage = ImageCreateTrueColor($newwidth,$newheight);
// Create a new JPEG image with new height and width

imagecopyresampled($newImage,$oldImage,0,0,0,0,$newwidth,$newheight,$width,$height);
ImageJPEG($newimage,\"$picture\");
// Old image will be added/pasted onto to the new image
// Create the image

copy($picture, \"PATH TO WHERE IMAGE WILL IMAGE BE COPIED\");
// Copy it to another directory

unlink(\"$picture\");
// Delete the image
?>

I think that should work..

brady.k — Fri, 26 Sep 2003 01:35:54 +0000

cool...

is there a way, that when someone uploads a picture/photo, it copies it to another directory, but resizes the image?

Example:
I upload a picture, named 'me.jpg'
It copies it to 'menew.jpg', and resizes it from 800x600 to 400x300

thanks for the help.

Ya beat me to it Andy
Good work

<?php
$SCRIPT_NAME=$SERVER_VARS['PHP_SELF'];
$pic=$HTTP_GET_VARS['pic'];

//    the directory name
$handle=opendir('full/');

//    initialize variables
$pics=array();
$count=0;
//    read directory into pics array
while (($file = readdir($handle))!==false) {
    //    filter for jpg, gif or png files...
    if (substr($file,-4) == \".jpg\" || substr($file,-4) == \".gif\" || substr($file,-4) == \".png\" || substr($file,-4) == \".JPG\" || substr($file,-4) == \".GIF\" || substr($file,-4) == \".PNG\"){
        $pics[$count] = $file;
        $count++;
    //    don't forget to close the filter conditions here!
    }
}
closedir($handle);

//    done reading, sort the filenames alphabetically, comment these lines if you want no sorting
 sort($pics);
 reset($pics);

        // loop over images
        for ($f=0;$f<=sizeof($pics)-1;$f++){

            echo \"<a href=\\"full/$pics[$f]\\" target=\\"_blank\\"><img src=\\"thumbs/$pics[$f]\\" hspace=\\"5\\" vspace=\\"5\\" border=\\"0\\"><br></a>\";
            // make linebreaks every 2 times!
            // $isbr = strpos((($f+1)/2),\".\");
            //    if (!$isbr){echo \"<br>\";}

            }
?>

I think it'll do what you need... let me know if you have any questions.

andy206uk — Thu, 25 Sep 2003 14:26:09 +0000

I have a script for doing this... I'll be back in a min with the code.

brady.k — Thu, 25 Sep 2003 02:04:03 +0000

wow, way over my head.

any links to check out other than the readdir() or examples that you can give me? the php.net link didn't make alot of sense, and I would rather try and write my own than copy someone's.
