php - Printing a field value in an array -

-

i'm using tutorial found here display directions based on google maps directions api in drupal. have 2 fields in node - originfield , destinationfield. each of them contains name of city.

the problem can't print field value inside of $params array. here whole tpl.php code:

<?php /**  * @file  * returns html node.  *  * complete documentation file available online.  * @see https://drupal.org/node/1728164  */ ?>  <?php // print works: print $node->field_originfield['und'][0]['value'];      // parameters used request     $params = array(         'origin'    => 'tokyo, japan', // can't find way output originfield's value here         'destination'   => 'kyoto, japan' // can't find way output destinationfield's value here     );      // join parameters url string     foreach($params $var => $val){         $params_string .= '&' . $var . '=' . urlencode($val);       }      // request url     $url = "http://maps.googleapis.com/maps/api/directions/json?".ltrim($params_string, '&');      // make our api request     $curl = curl_init();     curl_setopt($curl, curlopt_url, $url);     curl_setopt($curl, curlopt_returntransfer, 1);     $return = curl_exec($curl);     curl_close($curl);      // parse json response     $directions = json_decode($return);      // show total distance     print('<p><strong>total distance:</strong> ' . $directions->routes[0]->legs[0]->distance->text . '</p>');  ?>  // print works: <?php print $node->field_originfield['und'][0]['value']; print $node->field_destinationfield['und'][0]['value']; ?>

if manually add origin , destination works fine. if use of following combinations, whole page gets either messed , nothing displayed or nothing happens @ all.

'origin'    => "<?php print $node->field_originfield['und'][0]['value']; ?>" 'origin'    => "print $node->field_originfield['und'][0]['value'];" 'origin'    => "$node->field_originfield['und'][0]['value'];" 'origin'    => "field_originfield['und'][0]['value'];" 'origin'    => "field_originfield;" 'origin'    => "<?php print render($content['originfield']); ?>"

i have tried this, without luck:

$departure = print $node->field_originfield['und'][0]['value']; $arrival = print $node->field_destinationfield['und'][0]['value'];  'origin' => 'departure', 'destination'   => 'arrival'

what doing wrong here?

please try this:

$params = array(     'origin'    => $node->field_originfield['und'][0]['value'],     'departure' => $node->field_destinationfield['und'][0]['value'] );

or

$departure = $node->field_originfield['und'][0]['value']; $arrival = $node->field_destinationfield['und'][0]['value'];  $params = array(     'origin' => $departure,     'destination'   => $arrival );

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
