Before Save

apply_filters_ref_array( 'vikappointments_before_save_service', bool $save, mixed &$data, JTable $table )

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

$save

(bool)  Use false to abort the saving process.

&$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.

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  boolean  $save   False to abort the saving process.
 * @param  mixed    &$data  The array/object to bind.
 * @param  JTable   $table  The table instance.
 */
add_filter('vikappointments_before_save_service', function($save, &$data, $table)
{
    $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 $save;
}, 10, 3);
