Drupal 6 views field hanlder for two fields
In my custom module, I've got a table like this:
aid | int(10) unsigned
message | mediumtext
variables | mediumtext
This is similar to the schema for watchdog.
I want expose the message field to views (hook_views_data) but through a handler that translates it with the variables field. Something like this:
t($message, unserialize($variables))
Anyone know how to combine two fields and use a field handler to do this?
Here is my hoo开发者_Python百科k_views_data
/**
* Implementation of hook_views_data().
*/
function mymodule_views_data() {
$data['gccsi_activity']['aid'] = array(
'title' => t('Unique ID'),
'help' => t('The unique id'),
'sort' => array(
'handler' => 'views_handler_sort',
),
);
$data['gccsi_activity']['message'] = array(
'title' => t('Message'),
'help' => t('The message...'),
'sort' => array(
'handler' => 'views_handler_sort',
)
//here is where I want to create a handler that combines two fields
);
return $data;
}
Thanks
If you have implemented hook_views_data you can set the used handler.
$data['table']['column']['id']['field'] = array(
'handler' => 'yourmodule_handler_field_column',
);
Then you implement hook_views_handlers to register the used handler.
Then you write your handler and do the following steps. Let's assume you have one for message
a) in method construct you do
$this->additional_fields['variables'] = 'variables';
b) in method render do your previous stuff
t($values->{$this->field_alias}, unserialize($values->{$this->aliases['variables']}));
The views advanced help part is a good place to look up some general informations about viewsapi
as far as I know the handler class has to live in it's own file.
