[SOLVED] Save Image to Directory with GD

[hoopplaya4]

Hi All,

 

I'm currently using jCrop, a jquery tool to crop images.  I have no problems cropping the image, however, I'm not sure how I would save the image to a certain directory.

 

Here is my current code which exports the PNG file and displays it, but I'd like to save it to a directory:

 

<?php
if ($_SERVER['REQUEST_METHOD'] == 'POST')
{
$targ_w = $targ_h = 48;
$jpeg_quality = 90;

$src = 'demo_files/flowers.jpg';
$img_r = imagecreatefromjpeg($src);
$dst_r = ImageCreateTrueColor( $targ_w, $targ_h );

imagecopyresampled($dst_r,$img_r,0,0,$_POST['x'],$_POST['y'],
$targ_w,$targ_h,$_POST['w'],$_POST['h']);

header('Content-type: image/jpeg');
imagepng($dst_r,null,$png_quality);

exit;
} ?>

 

Would I need to use fwrite?  If so (or if not), how would I implement it into my current code?

 

Thanks.

Use the 2nd parameter in the imagepng function call. As always, the documentation for what you are doing supplies the answer most of the time - http://us2.php.net/imagepng

Thanks for the reply.  Okay, so I've added/modified the code to the following:

 

<?php

$save_file = "/home/username/public_html/jcrop/saved";

imagepng($dst_r,$save_file,$jpeg_quality)

 

But, it is not saving to the "saved" folder.  This folder is set to 777 permissions.  All it does is load the page, and then display the URL: http://www.mydomain.com/jcrop/crop.php  (Interestingly, I cannot copy/paste this text.

 

Not sure what I'm doing wrong here.  Any ideas?

your $save_file just has the path.  Where's the actual filename?

Hey crayonviolent, thanks for the reply.  I just figured that out as you were posting.  I wasn't giving it a filename.   

 

Thanks.
