Not sure why Im getting this error

sleepyescapade · 29-08-2008 4:35pm #1

Wondering if can someone help me. I'm uploading images through a form and trying to crop them. I found a function to crop them online. I have this in 'crop.inc'. I include this as

require('crop.inc');

and call it as

 cropImage(220, 160, '/images/prod_images/main/$id-1.jpg', 'jpg', '/images/prod_images/main/$id-1.jpg');

this is the crop.inc function that i got online

<?php
	  

function cropImage($nw, $nh, $source, $stype, $dest) {

		  $size = getimagesize($source);
		 $w = $size[0];
		  $h = $size[1];

		  switch($stype) {

			  case 'gif':
			  $simg = imagecreatefromgif($source);

			  break;

			  case 'jpg':
			  $simg = imagecreatefromjpeg($source);

			  break;

			  case 'png':
			  $simg = imagecreatefrompng($source);

			  break;

		  }

		  $dimg = imagecreatetruecolor($nw, $nh);
		  $wm = $w/$nw;
		  $hm = $h/$nh;

		  $h_height = $nh/2;
		  $w_height = $nw/2;

		  if($w> $h) {

			  $adjusted_width = $w / $hm;
			  $half_width = $adjusted_width / 2;
			  $int_width = $half_width - $w_height;

imagecopyresampled($dimg,$simg,-$int_width,0,0,0,$adjusted_width,$nh,$w,$h);

		  } elseif(($w <$h) || ($w == $h)) {
			  $adjusted_height = $h / $wm;
			  $half_height = $adjusted_height / 2;
			  $int_height = $half_height - $h_height;
			  imagecopyresampled($dimg,$simg,0,-$int_height,0,0,$nw,$adjusted_height,$w,$h);

		  } else {

			  imagecopyresampled($dimg,$simg,0,0,0,0,$nw,$nh,$w,$h);

		  }

		  imagejpeg($dimg,$dest,100);

	  }

?>

I think it may be not working as I am using a variable in the image name. I need to use a variable though. Anyone know any way around this?

Could you try this?

[php]
cropImage(220, 160, '/images/prod_images/main/'.$id-1.jpg.'', 'jpg', '/images/prod_images/main/'.$id-1.jpg.'');
[/php]

Thats it.

Remember OP, variables in double quotes "$myvar", are interpreted, IE -the variables value is placed there.
Anything enclosed in single quotes are string literals, meaning pass or print literally anything enclosed print '$myvar' will print exactly '$myvar' and not the value of var.

Same goes for escape characters such as new line "\n" or tab "\t".

The print out of $id-1.jpg in the warning is a hint that $id-1.jpg is not getting replaced with the actual value.

Thanks a million I'll give it a go on Monday

If I use the above I get

Parse error: syntax error, unexpected T_STRING in /hsphere/local/home/test/test/admin/test.php on line 69

And if I use

cropImage(220, 160, '/images/prod_images/main/'.$id.'-1.jpg', 'jpg', '/images/prod_images/main/'.$id.'-1.jpg');

I get the error

The cropImage function takes an image path from the filesystem, not from the web.

So when you're calling pointing at "/images/prod_images/main/", it's looking for a folder called "images" in the root of the filesystem as opposed to the root of the web server.

Use "/hsphere/local/home/test/images/prod_images/main/" instead.

sleepyescapade · 01-09-2008 11:31am

Thanks

but now Im getting:

Warning: imagejpeg(): Unable to open '/hsphere/local/home/test/test/images/prod_images/main/138-1.jpg' for writing in /hsphere/local/home/test/test/admin/crop.inc on line 94 Warning: imagejpeg(): Unable to open '/hsphere/local/home/test/test/images/prod_images/main/138-1.jpg' for writing in hsphere/local/home/test/test/admin/resize.inc on line 25 Warning: Cannot modify header information - headers already sent by (output started at /hsphere/local/home/test/test/admin/crop.inc:94) in /hsphere/local/home/test/test/admin/padd.php on line 75

seamus · 01-09-2008 11:43am

All fun and games.

You need to open up the folder /hsphere/local/home/test/test/images/prod_images/main/ as writeable to the webserver user.

sleepyescapade · 01-09-2008 1:56pm

Hmm permissions are already set to 757. Oh well. I'll figure it out, thanks for your help

Webmonkey · 01-09-2008 2:23pm

Are you sure that /hsphere/local/home/test/test/images/prod_images/main/ is the correct directory (2 test folders)

sleepyescapade · 01-09-2008 3:54pm

Yup

seamus · 01-09-2008 3:55pm

Chmod it to 777 so

sleepyescapade · 01-09-2008 4:25pm

Its all set to 777 and still getting the error of unable to write. Getting stressed now as this has to be working by tomorrow afternoon

Anyone know of a cropping image function that actually works :P

Webmonkey · 01-09-2008 5:05pm

By any chance are your pictures capital .JPG's - Remember Linux is case sensitive.
Some programs on windows (MS Paint) for example, have habit of saving to *.JPG instead of *.jpg

Edit - just a pure chance - I don't know if the file is locked since you are writing to the file you are resizing. Try imagedestroy($simg)

[php]
: : :

imagedestroy($simg);
imagejpeg($dimg,$dest,100);

}

?>
[/php]

sleepyescapade · 01-09-2008 5:12pm

No they are lowercase. Is this crop function working for anyone else? I really cant understand why it isnt writing the image to the folder

I have no clue of these functions I just got one online and I need to have it working by tomorrow afternoon

Webmonkey · 01-09-2008 5:22pm

I think you are going to have the same problem with another crop script as its file permissions thats the problem here.

I would try and create a script that creates a simple text file in that directory and see if you can.

[php]
<?php
$outputfile = "/hsphere/local/home/test/test/images/prod_images/main/testfile.txt";
$fh = fopen($outputfile, 'w') or die("Can't open for write, definetely permissions prob!");
$tempStr = "Testing";
fwrite($outputfile, $tempStr);
fwrite($fh, $stringData);
fclose($fh);

?>
[/php]

run this script and see if the text file exists in the directory. At least this will count out a few problems for you.

By the way - have you jsut Chmodded the images directory, make sure to chmod the main/ directory to 777

sleepyescapade · 01-09-2008 7:21pm

That's a good idea thanks i'll test that in the morning

Also does anyone know the correct syntax for cropping an image in php using mogrify?

sleepyescapade · 02-09-2008 9:24am

Warning: fwrite(): supplied argument is not a valid stream resource in /hsphere/local/home/test/test/test.php on line 5

Webmonkey · 02-09-2008 9:26am

Sorry that was wrong by me.

[php]
<?php
$outputfile = "/hsphere/local/home/test/test/images/prod_images/main/testfile.txt";
$fh = fopen($outputfile, 'w') or die("Can't open for write, definetely permissions prob!");
$tempStr = "Testing";
fwrite($fh, $tempStr);
fclose($fh);

?> [/php]

Now see if that file testfile.txt exists in the directory and it has the text Testing in it.

sleepyescapade · 02-09-2008 9:54am

Ok ive now discovered that the cropping and resizing functions are working (woo) but i still get this lovely error when i upload (but when i check the images in the folder they are there and appear cropped)

When working with file paths why not use

$target_path = 
$_SERVER['DOCUMENT_ROOT']."/images/prod_images/main/testfile.txt"

to make sure the path is right? Makes the code more portable too.

sleepyescapade · 02-09-2008 10:00am

Btw this is how Im calling the function in the form

	if($image1 != ""){
		exec("cp $image1 '$sitedir/images/prod_images/main/$id-1.jpg'");
		exec("mv $image1 '$sitedir/images/prod_images/$id-1.jpg'");
		cropImage(220, 160, '/hsphere/local/home/test/test/images/prod_images/main/'.$id.'-1.jpg', 'jpg', '/hsphere/local/home/test/test/images/prod_images/main/'.$id.'-1.jpg');
		cropImage(220, 160, '/hsphere/local/home/test/test/images/prod_images/'.$id.'-1.jpg', 'jpg', '/hsphere/local/home/test/test./images/prod_images/'.$id.'-1.jpg');
		resizethumb($id, 1, $thumbfolder, $thumbwidth, $thumbheight);
	     resizemain($id, 1, $mainfolder, $mainwidth, $mainheight);
	}
	Header("Location: done.php");
}

}

That code isn't very portablel

- - won't work on a windows machine. You are using the CLI to copy, using linux only functions such as cp and mv.

You should use the php copy function. Just something id advise

Just wondering how i could write the above with a variable '$k' substituting the '1' of the jpg?

eg: I tried writing it as
[php]
cropImage(220, 160, '/images/prod_images/main/'.$id'.'-'.$k.jpg'', 'jpg', '/images/prod_images/main/'.$id'.'-'.$k.jpg.'');
[/php]
but I get errors

Try this, you have your .'s in the wrong places.

[php]cropImage(220, 160, '/images/prod_images/main/'.$id.'-'.$k.'.jpg', 'jpg', '/images/prod_images/main/'.$id.'-'.$k.'.jpg'); [/php]

sleepyescapade · 04-09-2008 9:36am

Not sure why Im getting this error
