[PHP] Image upload and scaling

2002-03-11 Thread P.Agenbag 

Hi, I am trying to make a util whereby ppl can upload their own images to my server 
for me to automatically display them.
The below code works fine, but I have the following problem.
It only works fne if everyone complies to a standard of a set width and height for the 
image. This is not always possible, so I'm looking for a way to accept the image in 
any form they have and then to scale it 
to fit within an acceptable height/width range.
This I need help with, so if someone could hep me ( at the hand of my current code) I 
would be very pleased.

Thanks

Petre

below my code snippet


?php
if ($submit) {
if ($file != none) {

$current_time = time();
$location_pic = /home/www/imgs/listings/.$current_time.$file_name;
$url_pic = 
http://www.website.co.za/imgs/listings/.$current_time.$file_name;
copy ($file,$location_pic);
$db= mysql_pconnect(localhost,db_user,db_password);
mysql_select_db(DB_NAME,$db);
$sql = update table set location_pic = \$location_pic\, url_pic = 
\$url_pic\ where id = \$id_pic\ ;
$result = mysql_query($sql);

}
echo Picture Uploaded! Thank You!br;
echo Below is a preview of how your logo will look. If it displays 
incorrectly, adjust your image with an image editor of choice and upload again.br;
echo img src=\$url_pic\ width=\350\ height=\150\;
}else {
echo 
Please use this form to upload image.brbrbr
form method=\post\ action=\$PHP_SELF\ enctype=\multipart/form-data\
Logo Location : input type=\file\ name=\file\brbrbrbrPlease Note!Your 
image must be smaller than 50KB!
input type=\hidden\ name=\MAX_FILE_SIZE\ value=\5\
input type=\hidden\ name=\id_pic\ value=\$id\br
input type=\submit\ name=\submit\ value=\submit\
;}

Someone just mentioned ImageMagick... Check it out:

http://www.imagemagick.org/

ImageMagickTM is a robust collection of tools and libraries to read, write,
and manipulate an image in many image formats (over 68 major formats)
including popular formats like TIFF, JPEG, PNG, PDF, PhotoCD, and GIF. With
ImageMagick you can create images dynamically, making it suitable for Web
applications. You can also resize, rotate, sharpen, color reduce, or add
special effects to an image and save your completed work in the same or
differing image format. Image processing operations are available from the
command line, as well as through C, C++, Perl, or Java programming
interfaces.

Or you can check out the built in gd functions.
