Datensätze bearbeiten

In dieser Anleitung wollen wir als TYPO3-Erweiterungs-Entwickler ein Frontend-Management für Immobilien in einer Erweiterung integrieren. Unsere Eckdaten sind dabei:

  • Extension-Key: openimmo
  • Objekt-Name: Immobilie

Bearbeiten von Datensätzen

Das Formular für die Bearbeitung von Datensätzen wird mit TypoScript definiert.

Configuration/TypoScript/Frontend/Library/frontend.form.immobilie.typoscript

plugin.tx_openimmopro.settings.forms.immobilie {
    table = tx_openimmo_domain_model_immobilie
    #
    # Slug handling
    slug {
        # Enable auto generation for slugs
        active = 1
        # Database field for slug
        field = slug
        # Auto generate slug by using this fields
        fields = title,uid
    }
    #
    # Notify admin about inserted/updated records
    mailOnSave {
        # Enable notification mail on saving records
        active = 0
        subject = Record address saved on www.coding.ms
        fromEmail = typo3(at)coding(dot)ms
        toEmail = typo3(at)coding(dot)ms
    }
    messages {
        error {
            title = Error
            savingFailed = Please check your data.
        }
        success {
            title = Success
            successfullySaved = Your data was successfully saved.
        }
    }
    fieldsets {
        general < plugin.tx_modules.presets.fieldsets.normal
        general {
            label = General
            fields {
                hidden < plugin.tx_modules.presets.fields.checkboxHidden
                objekttitel < plugin.tx_modules.presets.fields.input
                objekttitel {
                    label = Title
                    placeholder = Title...
                    required = 1
                    validation {
                        NotEmpty = Please enter a title
                    }
                }
                objektnrExtern < plugin.tx_modules.presets.fields.input
                objektnrExtern {
                    label = Objectno. (external)
                    # Display field as readonly
                    readonly = 1
                    # Because we've a readonly field, we don't need a validation
                }
                slug < plugin.tx_modules.presets.fields.inputSlug
                slug {
                    table = tx_openimmo_domain_model_immobilie
                }
            }
        }

        buttons < plugin.tx_modules.presets.fieldsets.buttons
        buttons {
            fields {
                submit < plugin.tx_modules.presets.fields.submit
                cancelAndBackToListButton < plugin.tx_modules.presets.fields.cancelAndBackToListButton
            }
        }
    }
}

Die zugehörige editAction, welche die Logik zum Bearbeiten bereitstellt sieht wie folgt aus:

class ImmobilieController extends FrontendBaseController
{

    /**
     * @throws Exception
     */
    public function editAction() {
        $this->prepareAction();
        if($this->request->hasArgument('submit')) {
            // Read selectbox/checkboxes values from relations without select/check values
            $this->form = $this->prepareFormArray($this->form, $this->object, false);
            // Start validation of the form data
            $this->form = $this->validationService->validateForm($this->form, $this->request->getArguments(), $this->object);
            // Validation was successful?
            if ($this->form['valid'] === 0) {
                $this->addFlashMessage($this->form['messages']['error']['savingFailed'], $this->form['messages']['error']['title'], FlashMessage::ERROR);
            }
            else {
                $this->persistFormObject($this->form, $this->object);
                $this->addFlashMessage($this->form['messages']['success']['successfullySaved'], $this->form['messages']['success']['title'], FlashMessage::OK);
            }
        }
        else {
            // Pre fill object values
            $this->form = $this->objectValuesIntoFormArray($this->form);
            // Read selectbox/checkboxes values from relations and select/check values
            $this->form = $this->prepareFormArray($this->form, $this->object);
        }
        //
        $this->view->assign('formUid', 'immobilie-object');
        $this->view->assign('form', $this->form);
        $this->view->assign('frontendUser', $this->frontendUser);
        $this->view->assign('object', $this->object);
    }

}

In dieser Action werden die Eingaben entsprechend Deiner Konfiguration validiert und der Datensatz aktualisiert. Für die Ausgabe im Frontend benötigst Du dann noch das folgende Fluid-Template:
