[rafael_jp]

ninguem aki sabe?hehehe to precisando desse codigo mas teria q cria link pros arkivos mid e mp3 e nao mostra as paginas em php e htm alguem sabe fz isso?

[snkneo]

bom script..

mas gostaria de saber, como poderia fazer a paginacao para passar para o proximo arquivo.

Por exemplo, eu tenho uma pasta com fotos. Faco a listagem delas em miniaturas com link para abrir a foto grande em janela.

Ao abrir a pagina com 1 unica foto, precisava de um link para passar para a proxima imagem ou arquivo.

Como fazer isso ?

[snkneo]

encontrei na phpbrasil, esse codigo que faz oq eu preciso. Porem, as imagens se repetem.

Tentei entende-lo para alterar, mas nao achei como resolver.

<?php
$dir = 'pasta'

$filtro=".jpg;";
$nivel="";
$n_foto = 0;
$diraberto = opendir($dir); // Abre o diretorio especificado 
chdir($dir); // Muda o diretorio atual p/ o especificado 
while($arq = readdir($diraberto)) { // Le o conteudo do arquivo 
	if($arq == ".." || $arq == ".")continue; // Desconsidera os diretorios 
		$arr_ext = explode(";",$filtro);
		foreach($arr_ext as $ext) { 
		$extpos = (strtolower(substr($arq,strlen($arq)-strlen($ext)))) == strtolower($ext); 

		if ($extpos == strlen($arq) and is_file($arq))
		{ // Verifica se o arquivo é igual ao filtro
   			$foto[$n_foto] = $nivel.$arq; // Imprimi em forma de arvore 
			$n_foto++;
		}
			} 
			if (is_dir($arq)) { 
   				$foto[$n_foto] = $nivel.$arq; // Imprimi em forma de arvore 
				$n_foto++;
				varre($arq,$filtro,$nivel."&nbsp;&nbsp;&nbsp;&nbsp;"); // Executa a funcao novamente se subdiretorio 
				} 
		} 
		
		chdir(".."); // Volta um diretorio 
		closedir($diraberto); // Fecha o diretorio atual 
	if($nfoto < $n_foto){

		echo "<IMG SRC=\"$dir/$foto[$nfoto]\">";
		}
	else {	
		$nfoto = 0;
		echo "<IMG SRC=\"$dir/$foto[$nfoto]\">";
		}


?>
<form>
  <?php
	if($nfoto != 0)
	{
		$aux_foto = $nfoto - 1;
   		echo "<A HREF=\"fotos.php?id=$dir&nfoto=$aux_foto&play=cancelar\" class='menu1'><font size='2' face='Verdana, Arial, Helvetica, sans-serif'>Anterior</font></a>";

	}
	else
	{
		echo "&nbsp;&nbsp;";
	}

	echo "&nbsp;&nbsp;&nbsp;";
	if($nfoto != $n_foto-2)
	{
		$aux_foto = $nfoto + 1;
   		echo "<A HREF=\"fotos.php?id=$dir&nfoto=$aux_foto&play=cancelar\" class='menu1'><font size='2' face='Verdana, Arial, Helvetica, sans-serif'>Próxima</font></a>";
	}
	else
	{
		echo "&nbsp;&nbsp;";
	}

coisinha boba né ?
mais garanto que na hora do sufoco um se mata para achar algo assim.....

Usando paginação e dividido em coluna tableless (usando div's)
peguei um poco do victor e do redstyle, felipe juntei os 3

só para mostrar um exemplo em div, mais precisa tirar aquela segunda opção do felipe
depois do primeiro }else{ (senão) pq a div não tem erro é facinho para colunizar

fiz meio rapidaum so para dar um exemplo, pq todo mundo coloca em tabela, mais
é legal tb montar em DIV.

[lucianolaw]

testei os scripts e o inicial faz quase o que preciso

preciso listar os arquivos do diretorio mas preciso de links direcionando para download.

desde ja agradeço

obrigado

[Norefenk]

Tive problemas com o meu script, o primeiro que eu criei para rodar em outros servidores com a versão do
php 5.2.3 para cima e esse aqui funciona se quiserem usar em versão mais para cima. do mesmo.

<?php

#ESSE FUNFA COM  PHP 5.2.2.3


# Página
$pag = $_GET['pag'] ? $_GET['pag'] : 1;

# Registros por página
$rpp = 4;

# Inínio da página
$inicio = $pag * $rpp - $rpp;

# Diretório
$dir = "fotos/pre";

# Listando arquivos
$varrer = glob($dir."/*");

# Total de arquivos encontrados
$total = count($varrer);

# Número de páginas
$paginas = ceil($total/$rpp);

for ($i = $inicio; $i < $inicio+$rpp && $i < $total; $i++)
{
if($i%4==0)
 {
   if (substr("$varrer[$i]", -4) == ".jpg") 
   { 
	 echo ("</tr><tr><td><a href=\"#\" onClick=\"abre('$varrer[$i]')\"><img src='$varrer[$i]' width='80' height='60' border='0'></a></td>");
   }
 }
 else
 {
   if (substr("$dir/$varrer[$i]", -4) == ".jpg") 
   { 
   echo "<td><a href=\"#\" onClick=\"abre('$varrer[$i]')\"><img src='$varrer[$i]' width='80' height='60' border='0'></a></td>";
   }
 }
   
}



if ($pag > 1)
{
   $anterior = $pag - 1;
   print "&lt; <a href=\"{$_SERVER['PHP_SELF']}?pag={$anterior}\">Anterior</a> | ";
}

print "<em>Pagina <b>{$pag}</b></em>";

if ($pag < $paginas)
{
   $proxima = $pag + 1;
   print " | <a href=\"{$_SERVER['PHP_SELF']}?pag={$proxima}\">Proxima</a> &gt;";
}
