It might be that you missed to implement hook_token_list
as well. Providing a new token is a two step process:
- Implement
hook_token_list
to declare the tokens you are going to provide. This will just be the name of the tokens, along with a short explanation, and the information to what type of objects the tokens will apply (e.g. node, user, taxonomy, ...)
- Implement
hook_token_value
to actually generate the content of the tokens. This will be called when the tokens are to be replaced with the content they should stand for.
As you just want to provide an alternative version of the title token already provided by the token module, it is probably best to just copy the relevant portions from token_node.inc, stripped down to the relevant cases and adjusted to be used in another module:
/**
* Implementation of hook_token_list().
*/
function yourModule_token_list($type = 'all') {
if ($type == 'node' || $type == 'all') {
$tokens['node']['yourModule-title'] = t('Node title (customized version by yourModule)');
return $tokens;
}
}
This simply says that yourModule
provides a token for node objects, named yourModule-title
, along with a short description. The main work gets done in the other hook:
/**
* Implementation of hook_token_values().
*/
function yourModule_token_values($type, $object = NULL, $options = array()) {
$values = array();
switch ($type) {
case 'node':
$node = $object;
// TODO: Replace the check_plain() call with your own token value creation logic!
$values['yourModule-title'] = check_plain($node->title);
break;
}
return $values;
}
This will be called whenever the tokens for node objects are needed, with the node in question being passed as the $object
parameter (for a user token, the $type
would be 'user', and $object
would be the user object, and so on for other types). What it does is creating an array of values, keyed by the token name, with the replacement for that token as the value. The original code from token_node.inc just runs the title through check_plain()
, so this would be the place to insert your own logic.
