Before Delete
public function onBeforeDelete{$type}(array $ids, JTable $table) : bool
Fires before deleting a record.
Description
Trigger hook to allow the plugins to make something before deleting one or more records from the database.
The dynamic portion of the hook name, $type
, refers to the name of the table calling the hook. This means that, for example, the service table will trigger an hook called onBeforeDeleteService
. The name of the table is always equals to the base name of the file that declares the $table
instance.
It is possible to read a list of supported types by looking at the files stored within the following directory:
/administrator/components/com_vikappointments/tables/
TIP: in order to prevent the system from deleting the records, it is possible to throw an exception to abort the cancellation 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('You are not allowed to delete this record', 403);
// or register the error
$table->setError('You are not allowed to delete this record');
return false;
Parameters
- $ids
-
(array) An array of IDs to delete.
- $table
-
(JTable) The table instance that handles the cancellation process.
Return Value
Boolean. Use false to abort the cancellation process.
