php - Android post html data using a form -

i made app receives 3 text fields , needs send data website. have looked @ php code of main page , since i'm not php, i'm not sure how post data. here how form looks on site:

<div id="tzgb-homesearch-wrap">     <div id="tzgb-homesearch">                 <form method="post" action="http://www.online-bustickets.de/bus-departure-destination/">         <input type="hidden" id="_searchbox" name="_searchbox" value="77e642a333"><input type="hidden" name="_wp_http_referer" value="/">            <div class="search-row">             <label for="von">von</label>             <span role="status" aria-live="polite" class="ui-helper-hidden-accessible"></span><input type="text" id="von" name="von" placeholder="abfahrtsort eingeben" class="ui-autocomplete-input" autocomplete="off" mouseev="true" keyev="true" style="background-image: url(data:image/png;base64,ivborw0kggoaaaansuheugaaabaaaaaqcayaaaaf8/9haaabhkleqvq4eavto26dqbd1ohqwas2lg9jybz+ak7hnwx2oiovf4upq0lj1fdkktevipel8aknukdcwmxpgsaieatvv3sx7uztitdu2s/98dywow3dued4who/m2aix5lzv1aesy0+qiwhelyi+ytl0pq69sxaxkwia4rmrtdnske59jumcuzd6xiafez6fgcdj8ky4y7kautrngd7jyebxsdope3a0qgpsnionnymo67lgsqn9t41f2qgrqrrfcwyzoif2qybukkbcogpxdvey9rmwgnsjf9ccyesjhk3f5dyt1hx9gr0llqr30tnjkuecx2uius4rni+aj6sjr0am8aaumpam/rrehywhxqbfaa9kh3/8/nvhxaygasz/il8ialkclbfnvaaaaabjru5erkjggg==); padding-right: 0px; background-attachment: scroll; cursor: auto; background-position: 100% 50%; background-repeat: no-repeat no-repeat;">             <input type="hidden" id="von-permalink">         </div>         <div class="search-row">             <label for="nach">nach</label>             <span role="status" aria-live="polite" class="ui-helper-hidden-accessible"></span><input type="text" id="nach" name="nach" placeholder="zielort eingeben" class="ui-autocomplete-input" autocomplete="off">             <input type="hidden" id="nach-permalink">         </div>         <div class="search-row">             <label for="datum">datum</label>             <input type="text" id="datum" name="datum" readonly="readonly" class="hasdatepicker">         </div>         <div class="submit">             <input type="submit" id="tzgb-homesearch-submit" value="suchen">         </div>     </form>             </div> </div> 

my app need submit form using values entered in text fields. problem have doesn't use script.php file when submits, uses function class. here's code home.php:

<div id="tzgb-homesearch-wrap">     <div id="tzgb-homesearch">         <?php if ( class_exists( 'tzgb_busroute' ) ) global $tzgb_page_template; $tzgb_page_template->homesearch(); ?>     </div> </div> 

and here code function homesearch():

function homesearch() {     ?>     <form method="post" action="<?php bloginfo( 'url' ) ?>/bus-departure-destination/">         <?php wp_nonce_field( $this->noncekey, $this->noncefield ); ?>         <div class="search-row">             <label for="von">von</label>             <input type="text" id="von" name="von" placeholder="abfahrtsort eingeben" />             <input type="hidden" id="von-permalink" />         </div>         <div class="search-row">             <label for="nach">nach</label>             <input type="text" id="nach" name="nach"  placeholder="zielort eingeben"/>             <input type="hidden" id="nach-permalink" />         </div>         <div class="search-row">             <label for="datum">datum</label>             <input type="text" id="datum" name="datum" readonly="readonly" />         </div>         <div class="submit">             <input type="submit" id="tzgb-homesearch-submit" value="suchen" />         </div>     </form>     <?php } 

so, how post data website? need return webpage displayed in webview.

update code looks now:

httpclient httpclient = new defaulthttpclient();         httpconnectionparams.setconnectiontimeout(httpclient.getparams(),                 10000);         httpconnectionparams.setsotimeout(httpclient.getparams(), 10000);         httppost httppost = new httppost(                 "http://www.online-bustickets.de/bus-departure-destination/");         list<namevaluepair> namevaluepairs = new arraylist<namevaluepair>();         namevaluepairs.add(new basicnamevaluepair("_searchbox",                 "5624dd9868"));         namevaluepairs.add(new basicnamevaluepair("_wp_http_referer", "/"));         namevaluepairs.add(new basicnamevaluepair("von", "berlin"));         namevaluepairs.add(new basicnamevaluepair("nach", "alsfeld"));         namevaluepairs.add(new basicnamevaluepair("datum", "12.03.2014"));         // etc...         try {             httppost.setentity(new urlencodedformentity(namevaluepairs));             httpresponse response = httpclient.execute(httppost);              content = entityutils.tostring(response.getentity());                log.i("test", "" + response.getstatusline().getstatuscode());          } catch (unsupportedencodingexception e) {             // todo auto-generated catch block             e.printstacktrace();         } catch (clientprotocolexception e) {             // todo auto-generated catch block             e.printstacktrace();         } catch (ioexception e) {             // todo auto-generated catch block             e.printstacktrace();         } 

but when try open in webview page saying value von , nach not in database. have ideas problem might be?
