Recientemente baje un script para crear un buscador en mi pagina, para ser más especificos me baje el Smart Fetch.
Para los que no saben como funciona, el Smart Fetch es un buscador que funciona por medio de una base de datos en un archivo TXT. El mismo script te permite alimentar la base de datos, solo se llenan los campos requeridos.
El archivo TXT guarda la información segun el siguiente orden:
[list]; Titulo ; Descripción ; URL ; Palabras Clave;
Ahora, codigo utilizado para la busqueda es:
Código:
<html>
<head>
<style>
A:link {text-decoration: none; color: #11116E;}
A:visited {text-decoration: none; color: #11116E;}
A:hover {font-style: normal; color: #000000; text-decoration: underline;}
BODY {font-family: Verdana; font-size: 10pt; }
TD {font-family: Verdana; color: #000000; font-size: 8pt;}
SELECT {font-family:Verdana;font-size:10pt;background:#FFFFFF;color:#000000;}
INPUT {font-family:Verdana;font-size:10pt;background:#FFFFFF;color:#000000;}
TEXTAREA {font-family:Verdana;font-size:10pt;background:#FFFFFF;color:#000000;}
hr {color: #11116E; background-color: #11116E; height: 1px;}

Lo que yo quiero hacer es que aparescan en mi pagina los ultimos registros almacenados en el archivo TXT, como un listado para que las personas vean cuales son los nuevos registros.
No se si me explique bien, por lo cual si tienen alguna duda estoy a sus ordenes.
