Primero q nada gracias por tu respuesta Triby.
Precisamente no uso con base de datos porq soy novato aun, ademas busque muchos ejemplos pero la mayoria son scripts grandes y yo lo unico q quiero es un formulario con nick y texto para dejar un simple comentario, nada sofisticado.
Por eso opte por este sin db y mas adelante, cuando adquiera mas conocimientos, crear uno mejor.
Lo q no entendi es como relacionar el codigo q me dejaste con el script.
Este es el codigo q utiliza el sistema de comentarios:
Código PHP:
<?function open_file($id)
{
if(!file_exists('comments'))
mkdir('comments');
$file = 'comments/'.$id.'.txt';
$fp = @fopen($file, 'r');
if(!$fp)
{
$fp = fopen($file, 'w');
fclose($fp);
$fp = fopen($file, 'r');
}
return $fp;
}
// function to shorten long url
function shorten_long_words($str)
{
$maxwordlen = 30;
$replacement = '........';
$rpls = round(strlen($replacement)/2);
$words = explode(' ', $str);
for($i=0; $i<count($words); $i++)
{
$wordlen = strlen($words[$i]);
if( $wordlen > $maxwordlen)
{
$del = round(($wordlen - $maxwordlen)/2);
$mid = round($wordlen/2);
$start = $mid - $del - $rpls;
$end = $mid + $del + $rpls;
$first = substr($words[$i], 0, $start);
$last = substr($words[$i], $end);
$words[$i] = $first.$replacement.$last;
}
}
$str = implode(' ', $words);
return $str;
}
// stri_replace() function
// Avaliable in PHP 5 but defined as custom function for php 4 as stri_rep
function stri_replace($find,$replace,$string)
{
if(!is_array($find))
$find = array($find);
if(!is_array($replace))
{
if(!is_array($find))
$replace = array($replace);
else
{
// this will duplicate the string into an array the size of $find
$c = count($find);
$rString = $replace;
unset($replace);
for ($i = 0; $i < $c; $i++)
{
$replace[$i] = $rString;
}
}
}
foreach($find as $fKey => $fItem)
{
$between = explode(strtolower($fItem),strtolower($string));
$pos = 0;
foreach($between as $bKey => $bItem)
{
$between[$bKey] = substr($string,$pos,strlen($bItem));
$pos += strlen($bItem) + strlen($fItem);
}
$string = implode($replace[$fKey],$between);
}
return($string);
}

Y este es el q hice para mostrar la noticia con su caja de comentarios, q seria visor.php:
Código PHP:
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<title>Documento sin título</title>
<style type="text/css">
.style1 {
text-align: center;
font-size: xx-large;
}
</style>
</head>
<body style="background-color: #FFFFCC">
<?php include('db-cnx.php'); ?>
<table style="width: 100%" align="center">
<tr>
<td class="style1">
<?php
$not_ID = $_GET['not_ID'];
$sqlQueryNot = mysql_query("SELECT not_ID, notUser, notTitulo, notTexto FROM sn_noticias WHERE not_ID = '$not_ID'", $db_link)
or die(mysql_error);
while($rowNot = mysql_fetch_array($sqlQueryNot)){
echo $rowNot['notUser'];
echo "<h1>$rowNot[notTitulo]</h1>";
echo nl2br($rowNot['notTexto']);
}
?>
</td>
</tr>
</table>
<br>
<table style="width: 100%">
<tr>
<td>
<?php include('comments_ram.php'); ?>
<?php view_comments(1); ?>
</td>
</tr>
</table>
</body>
</html>
No se con cual de los dos relacionarlo.
