![]() ![]() the form again to correct the situation. if an error is found, $form->getErrors() will tell us. The processInput function can be intercepted for later validation. but it could have been another field or a Cancel button. The Send button is an excellent choice to check, The function createForm() is explained later. It will be empty or filled with given values. The function render() creates immediatly a form. Reading now continues through the code comments: public $values = If there are any errors, the form is resubmitted to the user with the data already completed. Once submitted, the form is first validated to see if the required data are present. ![]() Submitting a form is a three-step process: We will also use files from the core of ProcessWire.įor the purposes of this exercise, we will construct a two-column form. We will therefore have several files, the controller, the view and the css. This variable has been defined as global in the main controller MainController.php. We use Twig as a rendering engine (our template becomes a controller in its own right and the HTML rendering (the view) is moved to the Twig file, hence the call $this->view. On this subject, see: “ Various ways of accessing the ProcessWire API” : $config->useFunctionsAPI = true. The best place to insert the following command is in the config.php file. We have activated the call by function of the general variables of PW. Each field is a class that can be invoked. The ProcessWire code: the part we are interested in is wire/modules/Inputfield.“ ProcessWire API Reference.” Especially FormBuilder Class.“ W3Schools: How TO - Login Form.” It’s never too late to revisit the classics!.Surprisingly, the literature on this subject is rather sparse this article will attempt to explain it. However, knowing the workings of the Forms API is also essential in a more advanced programming context. This module, though not free, is affordable, and gives site administrators the freedom to develop their own forms. Programmers are spoiled with ProcessWire because they have access to an excellent form generation tool called FormBuilder. ![]()
