Usage is simple: Include the default palette (FORMHYBRID_PALETTE_DEFAULT) in config.php into your module's tl_module file and remove the fields you don't need for your module.

• form validation
• transforming of special field's values depending on their dca properties (e.g. date)

• optOut entity handling

Usage

Install

With composer and Contao 4 Managed Edition:

composer require heimrichhannot/contao-formhybrid ~2.8

Palette handling

• permanentFields must be declared within editableFields in order to get right field position
• a field declared in editableFields whose selector isnt active or is not part of editable fields itself is removed from the final field set
• fields from active selectors that are not within editableFields are removed from final fields

Inserttags

• {{form::FIELDNAME}} returns the formatted value from the field (select value instead of key)
• {{form_value::FIELDNAME}} returns the value of the field
• {{form_submission::FIELDNAME}} returns "field-label : formated field value"
• {{if}}
• {{elseif}}

Frontend Form

We recommend to use Contao Frontendedit. If you can't or need more advanced options:

• Create a module and add all palette fields you want (see config.php FORMHYBRID_PALETTE_DEFAULT and tl_module.php)
• add following code to your module::compile() method to render the form

use HeimrichHannot\FormHybrid\Form;

[...]
    $objForm = new Form($this);
    $this->Template->form = $objForm->generate();
[...]

More advanced configurations can be archived by extending the Form class and overwrite methods. Following methods are availiable to overwrite (no complete list, see Form and DC_Hybrid classes):

Hooks

JavaScript Events

Opt in handling

FormHybrid comes with build in opt-in handling. Following steps are required to use it:

• add formHybridAddOptIn to your modules palette
• add \HeimrichHannot\FormHybrid\FormHybrid::addOptInFieldToTable([TABLE_NAME]) at the end of your entity dca file and update your database
• create an opt in notification in notification center and provide ##opt_in_link## inside text or html

Opt out handling

FormHybrid comes with build in opt-out handling. After calling the opt-out link the entity will be deleted. Following steps are required to use it:

• add formHybridAddOptOut to your modules palette and activate it in module configuration
• add \HeimrichHannot\FormHybrid\FormHybrid::addOptOutFieldToTable([TABLE_NAME]) at the end of your entity dca file and update your database
• call HeimrichHannot\FormHybrid\TokenGenerator in your notification generation code with the opt-out-token from the database, to generate the opt-out-email-token and -url.
• add opt_out_token and opt_out_link to your notification center tokens and call them in your messages

Attention: If you enhance already existing data with opt-out-handling, tokens are not automatically generated for existing entries and unsubscription is not possible for existing entries! You need to check if the entry already has an token in your code, before generating opt-out link! Example:

if ($module->formHybridAddOptOut && !$recipientsModel->optOutToken)
{
    $recipientsModel->optOutToken = Form::generateUniqueToken();
    $recipientsModel->save();
}

Dublicate entity flag

Set Form::isDuplicateEntityError to true, to stop before saving and throw error message.

Customization
