Hi,
I have written a simple Dropdown Form with Submit Button, to change/select the page language.
Here is the code:
<?php
/*
* To change this template, choose Tools | Templates
* and open the template in the editor.
*/
class BootstrapNavbarLanguageForm extends Form {
public function __construct($controller, $name, $fields = null, $actions = null) {
$Laguages = array();
foreach(LocaleGeoip::get_available_languages() as $Locale => $Language){
$Languages[$Locale] = _t('BootstrapNavbarLanguageForm.'.$Language, $Language);
}
// Create fields
$fields = new FieldList(
$locale = new DropdownField('Locale', "", $Languages, i18n::get_locale())
);
$locale->addExtraClass('span2');
// Create actions
$actions = new FieldList(
$submit = new FormAction('updateLang', _t('BootstrapNavbarLanguageForm.SUBMIT','BootstrapNavbarLanguageForm.SUBMIT'))
);
$submit->addExtraClass('btn');
parent::__construct(
$controller,
$name,
$fields,
$actions
);
}
public function updateLang(array $data){
if($o_Member = Member::currentUser()) {
$o_Member->Locale = $data['Locale'];
$o_Member->write();
}
i18n::set_locale($data['Locale']);
Session::set('Locale', $data['Locale']);
Controller::curr()->redirectBack();
}
}Now I want this form to be used without the submit button. It just should submit on changing the dropdown. I know, I can work here with jQuery and that is not the problem.
But how to I create the code and the submit actions, without adding a(visible) submit button?
I can try to add an empty $action. But how do I tell the form, to use the updateLang method, when being submitted?
