Ricerca concatenata categorie wordpress

ciao a tutti,

sto cercando di realizzare una personalizzazione su un plugin wordpress.

Avendo infatti creato con wordpress un sito di annunci "classico", suddiviso per categorie città (es. roma) e categorie oggetto (es. abbigliamento donna), vorrei fare in modo che il visitatore, una volta entrato nel sito, abbia a disposizione in prima pagina un piccolo form, dove, selezionando la sua città e la categoria dell'oggetto (es. roma e abbigliamento donna) tramite due menu a tendina, e cliccando sul pulsante "cerca", visualizzi una pagina con presenti tutti i posts comuni alla categoria roma e abbigliamento donna (ossia tutti gli annunci inseriti sia nella categoria roma che abbigliamento donna). Non me ne intendo assolutamente di php, però credo si debba fare una sorta di funzione "and".

Ho provato ad informarmi riguardo ai plugin disponibili, ma l'unico che si avvicina a fare una cosa del genere è "super search", che comunque non consente questo tipo di concatenazione delle categorie nei risultati di ricerca.

Vorrei pertanto modificare questo plugin manualmente in modo da adattarlo alle mie esigenze.

Ho già provveduto a modificare il codice html, che incollo qui di seguito:

[HTML]<form action="annuncivisibili.it" method="get">
<select name="cat" id="ss_dropdown">

Allo stato attuale, il plugin prende in considerazione soltanto il secondo menu a tendina (in questo caso la categoria dell'oggetto), ignorando completamente la città, e mostrando pertanto i posts contenuti nella categoria dell'oggetto selezionata.

Qualcuno riuscirebbe gentilmente a darmi una mano?

Grazie anticipate.

Ciao erremetal,
Lo script prende in considerazione solo la seconda tendina perché le due select box hanno lo stesso name. Quando il form viene inviato, il secondo valore sovrascrive il primo, e nell'array $_POST trovi un solo valore 'cat', che corrisponde alla selezione della seconda select.

Ciao,
Luca

P.s. Ho inserito nel tuo post i tag html e php, così il codice ora è più leggibile. Cerca di utilizzarli sempre quando riporti del codice, sono buoni amici per ottenere più facilmente risposte alle tue domande

erremetal

Ciao Luca

grazie della risposta...anche se sono un lamer totale per quanto riguarda il php, credo di avere un pò capito la situazione.

Quindi perchè mi prenda in considerazione entrambi i menu a tendina e mi faccia vedere soltanto i post comuni ad entrambi le categorie selezionate, devo ad es. chiamare il primo select box in modo diverso (es. cat2), giusto?

E che codice devo aggiungere/modificare ai vari $_POST (suppongo) contenuti nella settings_page?

E' una cosa molto complessa da fare o modificando tre righe di codice si fa?:?

P.S. Si, scusa per il codice postato in modo disordinato, ma non so bene come funziona il forum, sono niubbo, porta pazienza
