A couple GD image questions
I have been working on the below snippet of code I found some place
and have a couple questions on it since I am not real femiliar with
the GD image commands.
1. How would I define a custom path to save the pictures in instead of
just putting the finished pictures in the same directory as the php
file.
2. How could I use the original file name of the picture and store
that in the database rather than renaming the file.
This is what I am working with
--------
<?php include 'db_connect.php'; ?>
<html>
<head>
<title>Upload a picture to your article</title>
<meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1">
</head>
<body>
<?php
articleid = artid;
//begin photo upload code
if (isset( _POST['photosubmit']))
{
// Filename to store image as (no extention)
FILENAME= rand(0,999999999);
// Width to reszie image to (in pixels)
RESIZEWIDTH=300;
// Width to reszie image to (in pixels)
RESIZEHEIGHT=400;
//start image function
function
ResizeImage( im, maxwidth, maxheight, name){
width = imagesx( im);
height = imagesy( im);
if(( maxwidth && width >
maxwidth) || ( maxheight && heightif( maxwidth && width >> maxheight)){
maxwidth){
widthratio = maxwidth/ width;
RESIZEWIDTH=true;
}
if( maxheight && height >
maxheight){
heightratio = maxheight/ height;
RESIZEHEIGHT=true;
}
if( RESIZEWIDTH && RESIZEHEIGHT){
if( widthratio < heightratio){
ratio = widthratio;
}else{
ratio = heightratio;
}
}elseif( RESIZEWIDTH){
ratio = widthratio;
}elseif( RESIZEHEIGHT){
ratio = heightratio;
}
newwidth = width * ratio;
newheight = height *
ratio;
if(function_exists("imagecopyresampled")){
newim =
imagecreatetruecolor( newwidth, newheight);
imagecopyresampled( newim,
im, 0, 0, 0, 0, newwidth, newheight, width,
height);
}else{
newim = imagecreate( newwidth,
newheight);
imagecopyresized( newim,
im, 0, 0, 0, 0, newwidth, newheight, width,
height);
}
ImageJpeg ( newim, name .
".jpg");
ImageDestroy ( newim);
} else {
ImageJpeg ( im, name . ".jpg");
}
}
//end image function
if( _FILES['image']['size']){
if( _FILES['image']['type']
== "image/pjpeg" ||
_FILES['image']['type'] ==
"image/jpeg"){
im =
imagecreatefromjpeg( _FILES['image']['tmp_name']);
}elseif( _FILES['image']['type']
== "image/x-png" ||
_FILES['image']['type'] ==
"image/png"){
im =
imagecreatefrompng( _FILES['image']['tmp_name']);
}elseif( _FILES['image']['type']
== "image/gif"){
im =
imagecreatefromgif( _FILES['image']['tmp_name']);
}
if( im){
if(file_exists(" FILENAME.jpg")){
unlink(" FILENAME.jpg");
}
ResizeImage( im, RESIZEWIDTH, RESIZEHEIGHT, FILENA ME);
ImageDestroy ( im);
}
//Submit picture
insert = "INSERT INTO pictures (
article_ref,
pic_name)
VALUES (
' articleid',
'". FILENAME.".jpg')";
article_pic = db_object->query( insert);
if (DB::isError( article_pic)) {
die( article_pic->getMessage());
}
db_object->disconnect();
?>
<B>Picture added successfully!</B> You can either
close this window or upload more pictures.
<?php
}
}
//end upload photo
?>
<form enctype="multipart/form-data"
method="post">
<b>Upload Image</b><br>
<input type="file" name="image"
size="50"><br>
<input type="submit" name="photosubmit"
value="Upload Photo"
onclick='refreshIframe()'>
</form>
</body>
