PHP Gallery

Anon

I'm very much new to PHP (about a week). I'm having trouble building a basic image gallery (as seen on Web Monkey). Basically I can get the images to display but I can't get the links at the bottom of the page to continue to the next set of images.

I've played around with it and I now get the following error:

Parse error: parse error in /var/www/vhosts/halfcab.net/httpdocs/photogallery/view.php on line 60

view.php has the following code in it....I can't figure out what is causing the problems:

<head>

<title>photo gallery</title>

</head>
<script language="javascript" src="photos.js">
</script>
<body bgcolor="#FFFFFF" text="#000000" link="#00CCFF" alink="#00CCFF" vlink="#00CCFF">

<?PHP

//initialize variables

$data_file = "list.photos";

$thumbnail_dir = "thumbs/";
$num_rows = 1;

$photos_per_row = 4;
$photos = file($data_file);
$total_photos = sizeof($photos);
$photos_per_page = $num_rows * $photos_per_row;
//check to see if the start variable exists in the URL.
//If not, then the user is on the first page - set start to 0

if(!isSet($start)){
	$start = 0;
}

//init i to where it needs to start in the photos array
$i = $start;
$prev_start = $start - $photos_per_page;
$next_start = $start + $photos_per_page;

for ($row=0; $row < $num_rows; $row++){
 	print("<tr>\n");
for ($col=0; $col < $photos_per_row; $col++){
	if($i < $total_photos){
	$thumbnail = $thumbnail_dir.trim($photos[$i]);
	$thumb_image_size = getimagesize($thumbnail);
	$image_size = getimagesize(trim($photos[$i]));
	print("<td align=\"center\"><br><a href=\"javascript:photo_open('photo_display.php?photo=".trim($photos[$i])."','".$image_size[0]."','".$image_size[1]."');\"><img src=\"".$thumbnail."\" ".$thumb_image_size[3]."></a></td>\n");									

	} else {
		print("<td></td>\n");
	}	
		$i++;
	}
		print("</tr>\n");
	}
//end table

<?PHP
//print out navigation links
if (($start == 0) && ($next_start < $total_photos)){
//you're at the beginning of the photo gallery
?>

<a href="view.php?start=<?PHP print($next_start): ?>">next page</a>
»

<?PHP
}
elseif (($start > 0) && ($next_start < $total_photos)){
//you're in the middle of the photo gallery
?>

«
<a href="view.php?start=<?PHP print($prev_start); ?>">prev page</a>
|

<a href="view.php?start=<?PHP print($next_start); ?>">next page</a>
»

<?PHP
}
elseif(($start == 0) && ($next_start > $total_photos)){
//you're in a photo gallery with only one page of photos
?>

<?PHP
}
else {
//you're at the end of the photo galley
?>

«
<a href="view.php?start=<?PHP print($prev_start); ?>
">prev page</a>

<?PHP
}
?>

</div>
</body>

Any help in getting this damn gallery functional would be appreciated 🙂

Would be helpful to post the code width line numbers...

replace the colon with a semicolon in your first link after print($next_start)
