如何在drupal中连接变量

Question

I want to know how can I concatenate [und][0][value]. I don't want to write every time [und][0][value]. So I have do like this:

   <?php

   $und_value = $load->field_testimonial_location['und'][0]['value'];

   $query = db_select('node','n');
   $query->fields('n',array('nid'));
   $query->condition('n.type','testimonial','=');
   $result = $testimonial_query->execute();

   while($fetch = $result->fetchObject()){

    $load = node_load($fetch->nid);
    // $location = $load->field_testimonial_location['und'][0]['value']; 
    $location = $load->field_testimonial_location.$und_value;
    echo $location;
   }

But its not working. It outputs Array Array So have any idia for this problem? How can I do? Full code here

Answer 1

Why don't you make some function which will take node field as parameter and return it's value

function field_value($field){
  return $field['und'][0]['value'];
}

Something like that (not tested).

But if you don't want to use function try using curly braces like:

$location = $load->{field_testimonial_location.$und_value};

That should work...
