Upload & Image Resize (Needs Work)

[bombski]

I have just finish creating a image resizing script and now I want it to resize an image when uploaded from a form.

I can't understand why I keep getting errors though. These are the errors:

Warning: Unable to access picture.jpg in /usr/local/psa/home/vhosts/reved-up.co.uk/httpdocs/test/sim_resize.php on line 9

Warning: getimagesize: Unable to open 'picture.jpg' for reading. in /usr/local/psa/home/vhosts/reved-up.co.uk/httpdocs/test/sim_resize.php on line 9

Warning: Division by zero in /usr/local/psa/home/vhosts/reved-up.co.uk/httpdocs/test/sim_resize.php on line 12

$file1 is the file upload field on the form. Here is the script:

<?

// resize function

function resize_jpg($img,$new_width,$quality){

// chmod ($img, 777);

$imagedata = getimagesize($img); 

//calculate the aspect ratio for resizing 
$aspectRat = (float)($imagedata[1] / $imagedata[0]); 

//calculate new x/y size, maintaining original aspect ratio 
if($imagedata[0] <= $new_width) { 
return; 
} 
else { 
$newY = $new_width * $aspectRat; 
$newX = $new_width; 
} 

$destImg = imagecreate($newX, $newY); 
$image = imagecreatefromjpeg($img); 

imagecopyresized ($destImg, $image, 0, 0, 0, 0, $newX, $newY, $imagedata[0], $imagedata[1]);

imagejpeg($destImg, $img, $quality);

}

// call resize function resize_jpg(image name, new width, quality)
resize_jpg($file1_name,250,80);

?>

Please Help. Thank you

Is your image in a separet directory? like: public_html/images/image.jsp. If so have you tried chmoding the dir?

[bombski]

Why would my image be in another folder when I'm uploading from a form. I have though made every folder and file 777.

Also, try using an Octel value for your mode instead of a decimal value:

chmod($file, 0777);

It appears that the script is looking for the image in the same directory as the script. (if $image_name is just the name, not the complete path) Should you be using $_FILES[]?
