I am not getting an image save using imagejpeg()

[jakebur01]

$watername is writable and when I echo $watername it shows the full path and filename to the image. The upload process that goes on before this watermark code does fine and the image and thumbnail is going into the directory fine. The image outputs to the browser fine with the watermark logo when I uncomment that part of the code out. I'm not sure why it's not saving/replacing the file in the directory.  I'm also not getting any errors when I turn reporting E_ALL on.

 

It does work when I create a blank test page with only watermark part of the code and manually type in the paths.

P.S. Where did everybody go?  It's been a few years since I was last on here, but there was a lot more activity back then.

What does

$filename = "$watername";
if (is_writable(dirname($filename))) {
    echo 'The file is writable';
} else {
    echo 'The file is not writable';
}

//echo "$watername";


imagejpeg($im, $watername , 90);

say?

PHP's not as popular as it used to be. Forums aren't as popular as they used to be. And as time goes by, more and more questions can be answered through Google.

The file is writable

 

 

When I take away the rest of the upload code and put the watermark code on it's on page and manually enter paths for the variables it overrites the image in the directory with the watermarked image fine.  There must be something in my surrounding upload code that's throwing a wrench in things.

When you manually enter the path are you putting in relative or full path?

[jakebur01]

relative

[ginerjm]

You first say the image and thumbnail are going into the directory (?).  But then you say the file is not being saved.  What are we talking about?

 

PS - see my signature to find the missing line you need for error checking displaying

[jakebur01]

This a regular image upload script I've had and used for a long time.  The time has come where I need to add a watermark on images for a particular site.  The image upload part is working correctly, meaning the regular upload script puts an image and thumbnail into the directory.

 

I'm attempting to add in this watermark code to watermark the image after it has been resized and put in the directory.  You'll see I added the watermark code in after the resizeImage function of the upload script.

 

However, the watermark code is not taking the image and resaving it to the directory.  It will in the script above output it to the browser if I comment out the imagejpeg and uncomment the header and imgpng, etc.

 

If I take the watermark code alone and put it in a separate test.php and key in the relative paths to the image that was uploaded using the upload script, it will work and resave the image with the watermark.

 

So, there must be something in the upload script that is conflicting with the watermark script I've added in.  When I get home I'll try repositioning it.  I may try moving it to after the thumbnail is created and see if it works there.

[requinix]

What if you try not replacing the resized image but saving the watermarked version as a new file?

 

And note your watermarking will only work on JPEG images.

[jakebur01]

I could try it.  Although, it doesn't have any trouble replacing it in the standalone test script without the upload code.

 

Thank's for pointing that out.  I'll determine the filetype and change the image***() accordingly.

 

 

I wonder if it is still processing the image when it is trying to access it.  In other words, when the watermark script is trying to access the image, it doesn't see it because the upload script hasn't finished creating it?

[jakebur01]

I moved it below the :

	//Resize image to our Specified Size by calling resizeImage function.
			if($processImage && resizeImage($CurWidth,$CurHeight,$BigImageMaxSize,$DestRandImageName,$CreatedImage,$Quality,$ImageType[$i]))
			{
				//Create a square Thumbnail right after, this time we are using cropImage() function
			
			
				if(!cropImage($CurWidth,$CurHeight,$ThumbSquareSize,$thumb_DestRandImageName,$CreatedImage,$Quality,$ImageType[$i]))
					{
						echo 'Error Creating thumbnail';
					}
			}
				

Now it works!
