Undefined Offset / Read Error!

[neridaj]

Hello,

I'm trying to figure out how to get rid of these errors:

Notice: Undefined offset: 1 in output_fns.php on line 315

Notice: getimagesize() [function.getimagesize]: Read error! in output_fns.php on line 315

function get_imgdim()
{
	$dir = get_imgdir();
	$files = scandir($dir);
	foreach($files as $value) {
		// check for image files
		if(valid_image_file($value)) {
			// build image array
			$imgarr[] = $value;
			$dimarr = array();
			$count = count($files);
			for($i = 0; $i < $count; $i++) {
				 $size = getimagesize($dir . $imgarr[$i]); // line 315
				 list($width, $height) = $size;
				 $dimarr[$imgarr[$i]] = array("width" => $width, "height" => $height);
			}		
		}
	}
	return $dimarr;
}

Thanks for any help,

Jason

if you stuck an echo $dir . $imgarr[$i]; as line 314, what does it show?

Presumably the $files array is not the same size as $imgarr, so you are basing your for loop on the size of $files but trying to reference an index to $imgarr that is not set. Not being sure what your intention is, perhaps $count should be set to count($imgarr), instead? (Or simpler yet, you could just do a foreach loop on $imgarr?)

Thanks NogDog!

You were right about the count, once changed to count($imgarr) all is well.

Cheers,
