# Change title of a content type

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.

Object of class stdClass could not be converted to int in garland_preprocess_node() (line 123 of C:\wamp\www\in2Tags\themes\garland\template.php). –  Vaibhav Jain Jan 13 '13 at 10:39

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

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($text); } }  Clear theme registry cache after adding a new preprocess function - I want to keep the title as serial number(because it is unique) but only while displaying I want to override it. – Vaibhav Jain Jan 13 '13 at 10:01 @vaibhav Answer updated with manual override option – David Thomas Jan 13 '13 at 10:11 I understand it now, but I guess this code snippet will override title of all content types. I want only products title to be overridden. Thanks. – Vaibhav Jain Jan 13 '13 at 10:26 OK, answer updated. That should do it :) – David Thomas Jan 13 '13 at 10:28 Thanks, it is quite interesting in template.php. Is there a way to know what properties$var has. Maybe a variable dump can work here. –  Vaibhav Jain Jan 13 '13 at 10:37
