Magento form validation

Validation classes

I often found my self looking on the net for the right classes to validate forms using the Prototype library that comes with Magento and finally decided to write a small post about the about validations.

Using these validations is as easy as using the following classes to the form fields in your forms.

'validate-no-html-tags' => 'HTML tags are not allowed'
'validate-select' => 'Please select an option.'
'required-entry' => 'This is a required field.'
'validate-number' => 'Please enter a valid number in this field.'
'validate-number-range' => 'The value is not within the specified range.'
'validate-digits' => 'Please use numbers only in this field. Please avoid spaces or other characters such as dots or commas.'
'validate-digits-range' => 'The value is not within the specified range.'
'validate-alpha' => 'Please use letters only (a-z or A-Z) in this field.'
'validate-code' => 'Please use only letters (a-z), numbers (0-9) or underscore(_) in this field, first character should be a letter.'
'validate-alphanum' => 'Please use only letters (a-z or A-Z) or numbers (0-9) only in this field. No spaces or other characters are allowed.'
'validate-alphanum-with-spaces' => 'Please use only letters (a-z or A-Z), numbers (0-9) or spaces only in this field.'
'validate-street' => 'Please use only letters (a-z or A-Z) or numbers (0-9) or spaces and # only in this field.'
'validate-phoneStrict' => 'Please enter a valid phone number. For example (123) 456-7890 or 123-456-7890.'
'validate-phoneLax' => 'Please enter a valid phone number. For example (123) 456-7890 or 123-456-7890.'
'validate-fax' => 'Please enter a valid fax number. For example (123) 456-7890 or 123-456-7890.'
'validate-date' => 'Please enter a valid date.'
'validate-date-range' => 'The From Date value should be less than or equal to the To Date value.'
'validate-email' => 'Please enter a valid email address. For example johndoe@domain.com.'

'validate-xml-identifier' => 'Please enter a valid XML-identifier. For example something_1, block5, id-4.'

'validate-zip-international' => 'Please enter a valid zip code.'
'validate-date-au' => 'Please use this date format: dd/mm/yyyy. For example 17/03/2006 for the 17th of March, 2006.'
'validate-currency-dollar' => 'Please enter a valid $ amount. For example $100.00.'
'validate-one-required' => 'Please select one of the above options.'
'validate-one-required-by-name' => 'Please select one of the options.'

'validate-css-length' => 'Please input a valid CSS-length. For example 100px or 77pt or 20em or .5ex or 50%.'
'validate-length' => 'Text length does not satisfy specified text range.'
'validate-percents' => 'Please enter a number lower than 100.'
'validate-cc-ukss' => 'Please enter issue number or start date for switch/solo card type.'

 

Here an example of how to use the validations when adding a field to a fieldset:

$fieldset->addField('title', 'text', array(
          'label'     => Mage::helper('form')->__('Title3'),
          'class'     => 'required-entryvalidate-alphanum',
          'required'  => true,
          'name'      => 'title',
          'onclick' => "alert('on click');",
          'onchange' => "alert('on change');",
          'style'   => "border:10px",
          'value'  => 'hello !!',
          'disabled' => false,
          'readonly' => true,
          'after_element_html' => '<small>Comments</small>',
          'tabindex' => 1
        ));
