<?php
function image_resize($src, $dst, $width, $height, $crop=0){
if(!list($w, $h) = getimagesize($src)) return "Unsupported picture type!";
$type = strtolower(substr(strrchr($src,"."),1));
if($type == 'jpeg') $type = 'jpg';
switch($type){
case 'bmp': $img = imagecreatefromwbmp($src); break;
case 'gif': $img = imagecreatefromgif($src); break;
case 'jpg': $img = imagecreatefromjpeg($src); break;
case 'png': $img = imagecreatefrompng($src); break;
default : return "Unsupported picture type!";
}
// resize
if($crop){
if($w < $width or $h < $height) return "Picture is too small!";
$ratio = max($width/$w, $height/$h);
$h = $height / $ratio;
$x = ($w - $width / $ratio) / 2;
$w = $width / $ratio;
}
else{
if($w < $width and $h < $height) return "Picture is too small!";
$ratio = min($width/$w, $height/$h);
$width = $w * $ratio;
$height = $h * $ratio;
$x = 0;
}
$new = imagecreatetruecolor($width, $height);
// preserve transparency
if($type == "gif" or $type == "png"){
imagecolortransparent($new, imagecolorallocatealpha($new, 0, 0, 0, 127));
imagealphablending($new, false);
imagesavealpha($new, true);
}
imagecopyresampled($new, $img, 0, 0, $x, 0, $width, $height, $w, $h);
switch($type){
case 'bmp': imagewbmp($new, $dst); break;
case 'gif': imagegif($new, $dst); break;
case 'jpg': imagejpeg($new, $dst); break;
case 'png': imagepng($new, $dst); break;
}
return true;
}
if(isset($_POST['submitButton'])){
$picture=$_FILES['image1'];
$pic_type = strtolower(strrchr($picture['name'],"."));
$pic_name = "original$pic_type";
move_uploaded_file($picture['tmp_name'], $pic_name);
if (true !== ($pic_error = #image_resize($pic_name, "100x100$pic_type", 100, 100, 1))) {
echo $pic_error;
unlink($pic_name);
}
else echo "OK!";
}
?>
<form method="post" action="" enctype="multipart/form-data" >
<p>
<input type="file" name="image1" />
</p>
<input type="submit" name="submitButton" value="save"/>
</form>
I have solved this by adding the folder path to both $pic_name & "100x100$pic_type":)

Answer 1

The first and second arguments of your
image_resize($src, $dst, $width, $height, $crop=0) function take source path and destination path to picture respectively.
So in your code you should edit the following part:
$pic_name = "original$pic_type";
move_uploaded_file($picture['tmp_name'], $pic_name);
if (true !== ($pic_error = #image_resize($pic_name, "100x100$pic_type", 100, 100, 1))) {
Currently your source path is specified as "original$pic_type" and destination path is specified as "100x100$pic_type", you may change it somehow you want.

Answer 2

if(isset($_POST['submitButton'])){
//function image_resize($src, $dst, $width, $height, $crop=0)
$tmpName = $_FILES['image1']['tmp_name'];
image_resize($tmpName, '/where/you/want/your/file', 300, 300)
// width and height just set a minimal width and height for the picture)
}
What you want is $dst, altrought, you can make this code better.
EDIT: you must specify a folder and a file name in the $dst, if you don`t know the file ext, you can add $dst as a folder, and inside the function you add a file name to it, like:
$dst = "/myfolder/toupload/"
$file = myfilename.".".$type
$dst .= $file;
