[SOLVED] Forward / Backward Buttons

[The Little Guy]

OK...

I use this PHP code to make my javascript array (this works):

<?php
$imgSQL = mysqli_query($db,"SELECT * FROM friends_images WHERE ownerID = '$id'");
$i = 0;
$imgCount = mysqli_num_rows($imgSQL);
echo 'var imagesArray = new Array('.$imgCount.');'."\n";
while($imgROW = mysqli_fetch_array($imgSQL)){
	echo 'imagesArray['.$i.'] = "'.$imgROW['id'].'";'."\n";
	$i++;
}
?>

 

I use this to go create a forward / backwards button (this doesn't work):

function rotateImage(dir,imageID){
for (i=0;i<imagesArray.length;i++){
	if(imagesArray[i] == imageID){
		var currlo = imagesArray[i];
		if(i++ == imagesArray.length){
			var next = imagesArray[0];
		}else{
			var next = imagesArray[i++];
		}
		if(i == 0){
			var prev = imagesArray[imagesArray.length];
		}else{
			var prev = imagesArray[i--];
		}
	}
}
document.getElementById('left').href  = 'javascript:rotateImage(\'left\',\''+prev+'\');';
document.getElementById('right').href = 'javascript:rotateImage(\'right\',\''+next+'\');';
}

 

How can I make forward / backwards buttons from the array that was created?

I don't really know what this is doing, so don't ask, I know how it "should" work, but it isn't doing that.

 

Anyone know how to make this better?
