Picture Gallery

I'm using a modifed http://tstar.taillandier.de/tstargallery_index.html as I want something very simple and it works great.

However, I don't want it to display all the pics on one page. There is a built in variable to limit the number across, but how do I limit the number down?

I.e. After 9 photos, I want there to be a next > option, and conversely a previous option.

Is this easy to impliment?

Hi there,

This should give you an idea: http://www.php-mysql-tutorial.com/php-mysql-paging.php

There are better tutorials out there, thats just an example, presuming your using MYSQL to index the images....

Thanks...

Any way for a non mysql enviroment?

Edited code is below.

Code:

<?php
$dirfiles = array();

$handle=opendir('.');
while ($file = readdir($handle)) {
   if
   ((
   strtolower(strrchr($file, '.')) == ".jpg" OR
   strtolower(strrchr($file, '.')) == ".jpeg" OR
   strtolower(strrchr($file, '.')) == ".png" OR
   strtolower(strrchr($file, '.')) == ".gif"
   )
   &&
   (
   strstr($file, ".thumb.jpg") == ''
   ))
   {
   	array_push($dirfiles, $file);
   }
}
sort ($dirfiles);
closedir($handle);

// Write the beginning of the basic table for displaying the thumbs.
// Modify this section to make it fit your own website.
// -----------------------------------------------------------------
echo "<table border=\"0\" width=\"100%\" id=\"table1\" cellspacing=\"10\" cellpadding=\"5\" bordercolor=\"#000000\"><tr>";


// Read the valid filenames from the array, have your way with every single one of them
// ------------------------------------------------------------------------------------

foreach($dirfiles as $aktuellesfile)
{
// Elements of the filename are cut into pieces
$dateiendung = strrchr( $aktuellesfile, '.' );
$dateiname = substr_replace ($aktuellesfile, '', -strlen($dateiendung) );


// First a routine for creating a thumb
createthumb ($dateiname, $dateiendung);
// Now open up a table cell
echo "<td width=\"180\" style=\"border-style: solid; border-width: 1px\"><center>";
// Second a routine for showing a thumb
showthumb ($dateiname, $dateiendung);
// Close the table cell
echo "</center></td>";
// And make a linebreak after every 5 thumbs
if(++$cnt % 3 == 0) echo "</tr>";
}

// Finished
exit;


// Function to create a thumbnail if it doesn't already exist
// -----------------------------------------------------------------
function createthumb ($thumbdateiname, $thumbdateiendung)
{
	$fullname = $thumbdateiname.$thumbdateiendung;
	$fullthumbname = $thumbdateiname.$thumbdateiendung.".thumb.jpg";

	// If thumb exists,nothing will happen
	if (file_exists($fullthumbname) OR strstr($fullname, ".thumb.jpg") != '')
	{
	}
	// If thumb doesn't exist,it's created now
  else
  {

		}

		$origx=imagesx($src_img);
  	$origy=imagesy($src_img);

		// Maximum width and height of the thumbnails
  	$max_x = 180;
  	$max_y = 135;

  	// Calc, if thumb has has to be squeezed from width or height
		if($origx >= $origy AND $origx > $max_x)
		{
		$faktor = $origx / $max_x;
		$new_x = $origx / $faktor;
  	$new_y = $origy / $faktor;
		}

		elseif($origy > $origx AND $origy > $max_y)
		{
		$faktor = $origy / $max_y;
		$new_x = $origx / $faktor;
  	$new_y = $origy / $faktor;
		}

		else
		{
		$new_x = $origx;
		$new_y = $origy;
  	}

  	// Squeeze and write it into a file
		$dst_img = imagecreatetruecolor($new_x,$new_y);
  	imagecopyresampled($dst_img,$src_img,0,0,0,0,$new_x,$new_y,imagesx($src_img),imagesy($src_img));
  	imagejpeg($dst_img, $fullthumbname, 50);
	}
}

// Function to show a thumbnail
// -----------------------------------------------------------------
function showthumb ($thumbdateiname, $thumbdateiendung)
{
	$fullname = $thumbdateiname.$thumbdateiendung;
	$fullthumbname = $thumbdateiname.$thumbdateiendung.".thumb.jpg";
	if (file_exists($fullthumbname))
	{
	echo "<a href=\"template.php?page=$fullname&heading=$thumbdateiname\" onclick=\"openMaxWindow(this.href);return false;\"><img src =\"$fullthumbname\" border=\"0\"></a>";
	}
