Buenas noches:
Tengo una página de música muy simple, es de archivos .mid. Tiene un buscador Real Time Full Text Search, que funciona bien.
Quisiera que en vez de mostrar las paginas .htm, me muestre solo los archivos de música .mid.
Espero que puedan ayudarme, les dejo un link de pruebas,
http://testingbusca.p.ht
Desde ya, muchas gracias Código PHP:

---------------------------------------------- Instructions -------------------------------------------------------------------------------------------
If the name of this file not is easy.php then rename it to easy.php
Upload it to the directory (folder) on your homepage server that you want to search through.
The PHP-script in this file performs a real time full text search of every htm, html, asp,
and php file in the directory (folder) and all subdirectories (subfolders). The search is
not case sensitive.
The text displayed in the browser window is searched. For that reason, in the html code, all
text in tags are omitted and also text between the tag and the end tag for head, script, noscript
and iframe.
You may translate the text (string values) in this file to your native language without the
author's permission. If you do so, please send a copy to [email protected] and it
will be published on the homepage of this script.
You may also use another CSS style and you may include the script as a natural part at pages at
your site.
