Respuesta: Alguien tiene un script php de paginacion que EN VERDAD FUNCIONE

Yo siempre uso este y me funciona muy bien.
Variables a modificar:
1. Code to connect to your DB - coloca o incluye tu conexion a la base de datos.
2. $tbl_name - nombre de la tabla.
3. $adjacents - cuantos adyacentes por lado.
4. $targetpage - la pagina donde se encuentre el script.
5. $limit - cuantos items se muestran por paginas.
6. "SELECT column_name - cambia por tu propia columna.
7. Modifica el bucle donde pone: while..loop here - colaca el bucle de resultados aqui.

Código:
<?php
	/*
		Place code to connect to your DB here.
	*/
	include('config.php');	// include your code to connect to DB.

	$tbl_name="";		//your table name
	// How many adjacent pages should be shown on each side?
	$adjacents = 3;
	
	/* 
	   First get total number of rows in data table. 
	   If you have a WHERE clause in your query, make sure you mirror it here.
	*/
	$query = "SELECT COUNT(*) as num FROM $tbl_name";
	$total_pages = mysql_fetch_array(mysql_query($query));
	$total_pages = $total_pages[num];
	
	/* Setup vars for query. */
	$targetpage = "filename.php"; 	//your file name  (the name of this file)
	$limit = 2; 								//how many items to show per page
	$page = $_GET['page'];
	if($page) 
		$start = ($page - 1) * $limit; 			//first item to display on this page
	else
		$start = 0;								//if no page var is given, set start to 0
	
	/* Get data. */
	$sql = "SELECT column_name FROM $tbl_name LIMIT $start, $limit";
	$result = mysql_query($sql);
	
	/* Setup page vars for display. */
	if ($page == 0) $page = 1;					//if no page var is given, default to 1.
	$prev = $page - 1;							//previous page is page - 1
	$next = $page + 1;							//next page is page + 1
	$lastpage = ceil($total_pages/$limit);		//lastpage is = total pages / items per page, rounded up.
	$lpm1 = $lastpage - 1;						//last page minus 1
	
	/* 
		Now we apply our rules and draw the pagination object. 
		We're actually saving the code to a variable in case we want to draw it more than once.
	*/
	$pagination = "";
	if($lastpage > 1)
	{	
		$pagination .= "<div class=\"pagination\">";
		//previous button
		if ($page > 1) 
			$pagination.= "<a href=\"$targetpage?page=$prev\">« previous</a>";
		else
			$pagination.= "<span class=\"disabled\">« previous</span>";	
		
		//pages	
		if ($lastpage < 7 + ($adjacents * 2))	//not enough pages to bother breaking it up
		{	
			for ($counter = 1; $counter <= $lastpage; $counter++)
			{
				if ($counter == $page)
					$pagination.= "<span class=\"current\">$counter</span>";
				else
					$pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";					
			}
		}
		elseif($lastpage > 5 + ($adjacents * 2))	//enough pages to hide some
		{
			//close to beginning; only hide later pages
			if($page < 1 + ($adjacents * 2))		
			{
				for ($counter = 1; $counter < 4 + ($adjacents * 2); $counter++)
				{
					if ($counter == $page)
						$pagination.= "<span class=\"current\">$counter</span>";

				}
				$pagination.= "...";
				$pagination.= "<a href=\"$targetpage?page=$lpm1\">$lpm1</a>";
				$pagination.= "<a href=\"$targetpage?page=$lastpage\">$lastpage</a>";		
			}
			//in middle; hide some front and some back
			elseif($lastpage - ($adjacents * 2) > $page && $page > ($adjacents * 2))

				$pagination.= "...";

				$pagination.= "<a href=\"$targetpage?page=$lastpage\">$lastpage</a>";		
			}
			//close to end; only hide early pages
			else
			{

				$pagination.= "<a href=\"$targetpage?page=2\">2</a>";
				$pagination.= "...";
				for ($counter = $lastpage - (2 + ($adjacents * 2)); $counter <= $lastpage; $counter++)
				{
					if ($counter == $page)
						$pagination.= "<span class=\"current\">$counter</span>";
					else
						$pagination.= "<a href=\"$targetpage?page=$counter\">$counter</a>";					
				}
			}
		}
		
		//next button
		if ($page < $counter - 1) 
			$pagination.= "<a href=\"$targetpage?page=$next\">next »</a>";
		else
			$pagination.= "<span class=\"disabled\">next »</span>";
		$pagination.= "</div>\n";		
	}
?>

	<?php
		while($row = mysql_fetch_array($result))
		{
	
		// Your while loop here
	
		}
	?>

<?=$pagination?>
Y como una imagen vale mas que mil palabras, una imagen explicativa. Las lineas en verde es lo que hay que modificar.



Tambien puedes añadir los estilos como prefieres, añade este codigo a tu hoja de estilos:
Código:
div.pagination {
	padding: 3px;
	margin: 3px;
}

div.pagination a {
	padding: 2px 5px 2px 5px;
	margin: 2px;
	border: 1px solid #AAAADD;
	
	text-decoration: none; /* no underline */
	color: #000099;
}
div.pagination a:hover, div.pagination a:active {
	border: 1px solid #000099;

	color: #000;
}
div.pagination span.current {
	padding: 2px 5px 2px 5px;
	margin: 2px;
		border: 1px solid #000099;
		
		font-weight: bold;
		background-color: #000099;
		color: #FFF;
	}
	div.pagination span.disabled {
		padding: 2px 5px 2px 5px;
		margin: 2px;
		border: 1px solid #EEE;
	
		color: #DDD;
	}
Espero que os funcione tan bien como a mi, un saludo.
