Module main class

This class helps to make new features, REST API methods, interacts with PBX core system

On the template repository, you can find an example in the file ModuleTemplate/Lib/TemplateConf.php You can use it for your project according to your preferences. The name of this class should be consist of a module unique identifier and ends with the Conf word.

Good examples:

• MyFirstModuleConf

• MikoCallTrackingConf

• TheBestModuleConf

Non-workable examples:

• TemplateConf

• MyFirstModuleConf1

• TheBestModuleConfig

The main MikoPBX module configuration class

After applying the instructions your config class will be renamed automatically.

getMethodPriority

This method allows overriding the execution priority of a method when called through hookModulesMethod. By defining this method in the Conf class of a module, you can flexibly control the execution priority of HOOK methods. This provides the ability to specify a high priority for a method that generates CRON tasks in an external module, and a low priority for a method that generates peers for pjsip.conf. By changing the priority, you can control the order in which module methods are applied.

Example:

/**
 * Allows overriding the execution priority of a method when called 
 * through hookModulesMethod.
 *
 * @param string $methodName The name of the method.
 * @return int The priority value assigned to the method.
 */
public function getMethodPriority(string $methodName = ''): int
{
    switch ($methodName) {
        case SystemConfigInterface::CREATE_CRON_TASKS:
            $result = 200; // Set a high priority for the method "CREATE_CRON_TASKS"
            break;
        case AsteriskConfigInterface::GENERATE_PEERS_PJ:
            $result = 50000; // Set a low priority for the method "GENERATE_PEERS_PJ"
            break;
        default:

onVoltBlockCompile

The function compiles a Volt block and provides the file path of the compiled template. All available blocks can be found in the src/AdminCabinet/Views folder. For example, in the Asterisk manager modify form, there is a block called MainFields, which is represented in the Volt file using the following syntax:

{{ partial("PbxExtensionModules/hookVoltBlock",
                ['arrayOfPartials':hookVoltBlock('MainFields')]) 

Example:

/**
 * Compiles a Volt block and returns the compiled template file path.
 *
 * @param string $controller The name of the controller.
 * @param string $blockName The name of the block.
 * @param View $view The View instance.
 *
 * @return string The compiled template file path.
 */
public function onVoltBlockCompile(
        string $controller, string $blockName, View $view): string
{
    $result = '';

    // Combine the controller and block name to create a unique case identifier
    $caseIdentifier = "$controller:$blockName";

    // Check the combined case identifier to determine the template file path
    switch ($caseIdentifier) {
        case 'AsteriskManagers:MainFields':
            // Add fields to the main tab on the AsteriskManager edit page
            $result = "{$this->moduleDir}/App/Views/AsteriskManagers/mainfields";
            break;
        case 'Extensions:GeneralTabFields':
            // Add fields to the general tab in the advanced settings section 
            // on the Extension edit page
            $result = "{$this->moduleDir}/App/Views/Extensions/generaltabfields";
            break;
        case 'Extensions:TabularMenu':
            // Add an additional tab to the Extension edit page
            $result = "{$this->moduleDir}/App/Views/Extensions/tabularmenu";
            break;
        case 'Extensions:AdditionalTab':
            // Add content for an additional tab on the Extension edit page
            $result = "{$this->moduleDir}/App/Views/Extensions/additionaltab";
            break;
        default:
            // No specific template file path for other case identifiers
    }

    return $result;

Forms

onBeforeFormInitialize

Initializes the form before it is rendered. It useful to add an extra form fields before it compile.

Example:

/**
 * Initializes the form before it is rendered.
 *
 * @param Form $form The form object.
 * @param mixed $entity The entity associated with the form.
 * @param mixed $options Additional options for the form initialization.
 *
 * @return void
 */
public function onBeforeFormInitialize(Form $form, $entity, $options): void
{
    // Check if the form is an instance of ExtensionEditForm
    if (is_a($form, ExtensionEditForm::class)) {
        // Define an array of DTMF types with their corresponding translations
        $arrDTMFType = [
            'auto' => $this->translation->_('auto'),
            'inband' => $this->translation->_('inband'),
            'info' => $this->translation->_('info'),
            'rfc4733' => $this->translation->_('rfc4733'),
            'auto_info' => $this->translation->_('auto_info'),
        ];

        // Create a Select element for the 'module_dtmfmode' field
        $dtmfmode = new Select(
            'module_dtmfmode',
            $arrDTMFType,
            [
                'using' => [
                    'id',
                    'name',
                ],
                'useEmpty' => false,
                'value' => 'auto',
                'class' => 'ui selection dropdown',
            ]
        );

        // Add the DTMF mode field to the form
        $form->add($dtmfmode);
    }
}

Sidebar menu

onBeforeHeaderMenuShow

Modifies the sidebar menu items before it is shown.

Example:

/**
 * Modifies the sidebar menu items before it is shown.
 *
 * @param array $menuItems The menu items for modifications.
 * 
 * @return void
 */
public function onBeforeHeaderMenuShow(array &$menuItems):void
{
     // Add Module Users UI Admin menu item
    $menuItems['ModuleUsersUIAdmin']=[
        'caption'=>'module_usersUiMainMenuItem',
        'iconclass'=>'',
        'submenu'=>[
            '/module-users-ui/access-groups'=>[
                'caption' => 'module_usersUiAccessGroups',
                'iconclass' => 'gear',
                'action' => 'index',
                'param' => '',
                'style' => '',
            ],
        ]
    ];
