Php Image creation and upload to folder - php

Question

I want to create a image dynamically and upload it to a folder. I will be getting image for body,sleeve,collar and cuff dynamically from user selection. I am merging all these images to create a new image and this new image to uploaded in a folder. Am not able to upload the filename to folder and there is no errors displaying also but am able to generate the merged image.
Below is code,
<?php
$body = "img1.jpg";
$sleeve = "img2.jpg";
$collar = "img3.jpg";
$cuff = "img4.jpg";
$outputImage = imagecreatetruecolor(800, 800);
$background = imagecolorallocate($outputImage, 0, 0, 0);
imagecolortransparent($outputImage, $background);
$white = imagecolorallocate($outputImage, 255, 255, 255);
imagefill($outputImage, 0, 0, $white);
$first = imagecreatefrompng($body);
$second = imagecreatefrompng($sleeve);
$third = imagecreatefrompng($collar);
$fourth = imagecreatefrompng($cuff);
imagecopyresized($outputImage,$first,0,0,0,0,600,600,600,600);
imagecopyresized($outputImage,$second,0,0,0,0,600,600,600,600);
imagecopyresized($outputImage,$third,0,0,0,0, 600, 600, 600, 600);
imagecopyresized($outputImage,$fourth,0,0,0,0,600,600,600,600);
$filename = round(microtime(true)).'.png';
imagepng($outputImage, $filename);
define('DIR_IMAGE', '/opt/lampp/htdocs/dutees/image/design-uploads/');
$ret = move_uploaded_file($filename, DIR_IMAGE.$filename);
print_r(error_get_last());
if($ret)
{
echo "success";die;
}
else
{
echo "fail";die;
}
imagedestroy($outputImage);
?>echo "fail";die;
}
imagedestroy($outputImage);
?>

Answer 1

move_uploaded_file won't work on $filename because it's not an uploaded file - it was just created by your code.
Try switching the two lines (like below) and adding your path:
define('DIR_IMAGE', '/opt/lampp/htdocs/dutees/image/design-uploads/');
imagepng($outputImage, DIR_IMAGE . $filename);
And remove the move_uploaded_file line:
//$ret = move_uploaded_file($filename, DIR_IMAGE.$filename);

Answer 2

you are using imagepng(), That saves file to particular location you are providing.
Syntax for imagepng() :
bool imagepng ( resource $image [, mixed $to [, int $quality [, int $filters ]]] )
where $to refers to location where you want to save your image (including filename).
So instead of
$filename = round(microtime(true)).'.png';
imagepng($outputImage, $filename);
define('DIR_IMAGE', '/opt/lampp/htdocs/dutees/image/design-uploads/');
$ret = move_uploaded_file($filename, DIR_IMAGE.$filename);
Try This,
$filename = round(microtime(true)).'.png';
define('DIR_IMAGE', '/opt/lampp/htdocs/dutees/image/design-uploads/');
imagepng($outputImage, DIR_IMAGE.$filename);
You don't need move_uploaded_file() anymore, because the image created is already in your server.
I also had similar problem while creating captcha for new users, and This solution worked.

Answer 3

You should try file_put_contents instead of move_uploaded_file.
file_put_contents('you_file_location/filename', IMAGE_OBJECT_HERE);
or you can also save file using fwrite function.
