Adding attributes in a form
23 November 2009 at 4:58pm
Hi! I'm a newbie in silverstripe and I would just like to ask if how can i add an attribute in a form? For example i want to add onsubmit=''return false;" and class="myClass". Here is the function that I'm using:
public function NewsletterForm() {
$fields = new FieldSet(
new EmailField('Email','')
);
$actions = new FieldSet(
new FormAction('NewsletterSubmit', 'Ok!')
);$validator = new RequiredFields('Email','onsubmit');
return new Form($this, 'NewsletterSubmit', $fields, $actions,$validator);
}/**
* Inserts a submitted email to database
* @param <type> $form
*/
public function NewsletterSubmit($form) {
$newsletter = new Newsletter();
$newsletter->Email=$_POST['Email'];
$newsletter->write();
return Director::redirectBack();
//Director::redirect(Director::currentURLSegment()."?msg=Thank+you+for+signing+up!");
}Any help will be much appreciated. Thanks!

<form name="frmName" method="post" action="home/newsletterSubmit" class="myClass" onsubmit="return false;">
i just want to add class and onsubmit attributes in this form.

To get precise control over your forms I would recommend you extend the form class. This will allow you to override many defaults that "just work" to make subtle changes like you want. See the FormAttributes call.
class NewsletterForm extends Form {
public function __construct($controller, $name) {
$fields = new FieldSet(
new EmailField('Email','')
);$actions = new FieldSet(
new FormAction('NewsletterSubmit', 'Ok!')
);$validator = new RequiredFields('Email');
return parent::__construct($controller, $name, $fields, $actions, $validator);
}public function NewsletterSubmit($form) {
$newsletter = new Newsletter();
$newsletter->Email=$_POST['Email'];
$newsletter->write();
Director::redirectBack();
}// This is what gets put your form line in Form.ss <form $FormAttributes>
public function FormAttributes() {
$attr = parent::FormAttributes();
// Do your manipulations
$attr .= ' onSubmit="return false;"'
return $attr;
}
}In your page controller you would herely change your current code to
public function NewsletterForm() {
return new NewsletterForm($this,'NewsletterForm');
}Hope this helps!
