Magento – AJAX validation form in custom backend module

backendformsjavascriptmagento-1module

I create custom module and would like to validate the input fields such date.

I tried in Form.php

public function _prepareForm()
{        
    $form = new Varien_Data_Form(array(
        'id'     => 'edit_form',
        'method' => 'post'
    ));

    $f = $form->addFieldset('User', array(
        'legend' => 'Add User',
        'class'  => 'fieldset-wide'
    ));

    $f->addField('to', 'date', array(
        'name'     => 'to',
        'label'    => 'Date to',
        'format'   => 'DD-MM-YYYY',
        'class'    => 'validate-date',
        'required' => true
    ));
}

But the class is not added, and nothing does it.

What am I doing wrong?

Try validate_class, not class

$f->addField('to', 'date', array(
    'name'     => 'to',
    'label'    => 'Date to',
    'format'   => 'DD-MM-YYYY',
    'validate_class'    => 'validate-date',
    'required' => true
));

look at Mage_Adminhtml_Block_Catalog_Product_Edit_Tab_Related as an example.

Magento – Setting AJAX URL for custom module

in app/design/frontend/{interface}/{theme}/template/checkout/onepage.phtml add this code somewhere at the top of the template:

<script type="text/javascript">
var baseUrl = '<?php echo Mage::getUrl('');?>';
</script>

now you should be able to use in your js file this:

url : baseUrl + "/collivery/ajax/cptypes",

Actually you can add the script anywhere in the template (header, footer, ...) just make sure it's in the page you need. Since the checkout page is the only one you need, I suggested adding it in the onepage template.

Magento – Return errors to form

It is better to tie the validate methods to the model. In your model you can include the validate method as follows:

public function validate() {
    $errors = array();

    if (!Zend_Validate::is($this->getFirstName(), 'NotEmpty')) {
        $errors[] = 'First name is needed';
    }

    if (!Zend_Validate::is($this->getLastName(), 'NotEmpty')) {
        $errors[] = 'Last name is needed';
    }

    if (!Zend_Validate::is($this->getDesignation(), 'NotEmpty')) {
        $errors[] = 'Designation is needed';
    }

    if (empty($errors)) {
        return true;
    }

    return $errors;
}

Then in the controller you can use it as follows:

if ($data = $this->getRequest()->getPost()) {

        $users = Mage::getModel('tableop/users')->setData($data);

        $session = Mage::getSingleton('tableop/session');

        $validate = $users->validate();         
        if ($validate === true) {

....etc

For the error and success messages part, you can use Mage::getSingleton('core/session')->addError or addSuccess methods. You can use your own session objects also.
