Change title of a content type

Question

I have a custom content type named 'product'. Every content of type product has a serial number of the product as the title. But while displaying the title I want to override it from two of the CCK fields of the product. Please take a look at this page.

I want to concatenate Manufacturer and Chip and display it as the title. I am a beginner in Drupal.

For altering the saved title, try auto_nodetitle module, it can do what you want there.

1. Download and install the module
2. Enable the module in Drupal
3. Edit the relevant content type settings ( Admin > Structure > Content types )
4. Set the Automatic title generation option, using field tokens for the field values

If you want to update the display only, then you can use a node.tpl.php template preprocess function

e.g in your theme template.php file, replace THEMENAME with your theme name.

function THEMENAME_preprocess_node(&$vars){
  $node &= $vars['node'];
  if ($node->type == 'product') {
    $text = $node->field_manufacturer[LANGUAGE_NONE][0]['value'] . ' ' . $node->field_chip[LANGUAGE_NONE][0]['value'];
    $vars['title'] = check_plain($text);
  }
}

Clear theme registry cache after adding a new preprocess function
