Ciao a tutti!
sto testando il nuovo motore di ricerca Finder, gran balzo in avanti, non c'è che dire.
Adesso sto provando a far visualizzare il modulo di ricerca. Mi compare: il form di ricerca e il link a "ricerca avanzata". Fra le opzioni non c'è un campo che mi consenta di richiamare la funzione filtro che vedo invece comparire nel componente.
La cosa invece mi pare interessante e stavo cercando un modo per risolvere.
Non conosco il PHP, ma solo HTML/CSS, a lume di naso mi viene da pensare che basterà richiamare la funzione nel file del modulo "motore di ricerca", credo default.php nella cartella tmpl
o incollare la parte di codice nella giusta posizione prelevandola dal componente.
E qui viene il busillibus per un ignorante di php.
Qui c'è il codice di filter.php (dal componente finder), quale porzione mi interessa, ma soprattutto, è giusto il mio ragionamento?
Grazie a tutti e spero sia utile anche ad altri.
