Motore di Ricerca per il tuo sito (Php + Yahoo).
Ho cercato molte volte un prodotto che potesse fare le ricerche interne al mio sito. Ci sono molti prodotti ma tutti o quasi obbligano and inserire il loro logo o il loro template. Insomma non danno la possibilità di personalizzare al 100% la ricerca sul vostro sito. Così ho ho utilizzato le API di Yahoo e PHP 5(Non penso funzioni con versioni inferiori) e ho modificando il loro script ho creato un motore di ricerca locale per il tuo sito. Qui potete fare delle prove
Sono necessari solo due file common.php e index.php , la richiesta della API key a Yahoo e l’inserimento del vostro sito. E siete pronti ad andare.
Vi inserisco i file qui. (Non linkate direttamente ai file ma alla pagina)
E qui di seguito il codice:
common.php
<?php

$yoursite = ”;//if empty searches on the web. Example: ‘&site=www.mysite.com’$service = array(‘web’=>’http://search.yahooapis.com/WebSearchService/V1/webSearch’,
‘image’=>’http://search.yahooapis.com/ImageSearchService/V1/imageSearch’);header(‘Content-Type: text/html; charset=UTF-8’);
