Before Save
public function onBeforeSaveService(mixed &$data, JTable $table) : bool
Fires before saving a service.
Description
This hook is triggered before creating or updating a service record. It can be used to bind the data that are going to be saved within the database.
TIP: in case of failure while saving the record, it is possible to throw an exception to abort the saving process and return a readable error message. The same can be accomplished by registering an error to the table and returning false
.
// throw an exception
throw new Exception('Missing required field', 404);
// or register the error
$table->setError('Missing required field');
return false;
Parameters
- &$data
-
(array|object) Either an array or an object specifying the service properties to bind.
- $table
-
(JTable) The table instance that handles the saving process.
Return Value
Boolean. Use false to abort the saving process.
Example
The following example is used to save a new property that is not supported by default. It is assumed that the services database table has been altered to support the difficulty column.
/**
* Trigger hook to allow the plugins to bind the object that
* is going to be saved.
*
* @param mixed &$data The array/object to bind.
* @param JTable $table The table instance.
*
* @return boolean False to abort the saving process.

$input = JFactory::getApplication()->input;
// retrieve DIFFICULTY from request
$difficulty = $input->get('difficulty', null, 'string');
// make sure the difficulty was set
if (!is_null($difficulty))
{
// bind array with difficulty to include it within the UPDATE/INSERT query
$data['difficulty'] = $difficulty;
}
return true;
