R – zend framework custom validation classes

zend-framework

I'm writing a custom validator that is going to check for the existence of an email such that if it already exists in the database, the form is not valid. I'm having a hard time figuring out helper paths and namespaces for custom Zend_Validation classes.

I'd like to call the class My_Validate_EmailUnique but I keep getting error messages such as:
there is an error exception 'Zend_Loader_PluginLoader_Exception' with message 'Plugin by name 'My_Validate_EmailUnique' was not found in the registry; used paths: My_Validate_: /var/www/site/arc/helpers/

The class looks like this:

    <?php
class My_Validate_EmailUnique extends Zend_Validate_Abstract
{
    const EMAIL_UNIQUE = 'notMatch';

Can someone help me with where I register for the Zend_Form to look for custom validators?

You can directly add the validator to your form element. There is no need to write a custom validator for this.

In your form:



$element->addValidator(new Zend_Validate_Db_NoRecordExists('mytablename', 'myemailcolumnname'));

Zend: Where/how can I register custom view helpers

Using application.ini is probably the best way to define these. I put all my view helpers inside my library folder:

includePaths.library = APPLICATION_PATH "/../library"
autoloadernamespaces.0 = "SNTrack_"

;  -- Note, these are the only resources.view lines I have...
resources.view.doctype = "XHTML1_STRICT"
resources.view.helperPath.SNTrack_View_Helper = APPLICATION_PATH "/../library/SNTrack/View/Helper"

Directory structure:

/
  application/
  library/
    SNTrack/
      View/
        Helper/
          Test.php

View:

 $this->test('test')

SNTrack/View/Helper/Test.php:

 class SNTrack_View_Helper_Test extends Zend_View_Helper_Abstract {
   public function test($args) { return $args; }
 }

Your helper must have the same name than your method. Change Zend_View_Helper_Dropdownhelper into Zend_View_Helper_GetBlnCompany and it will work. Don't forget to change your filename too: GetBlnCompany.php

In order to use a proxy method, you simply need to return $this;:

// /application/views/helpers/helpers/GetBlnCompany.php
class Zend_View_Helper_GetBlnCompany extends Zend_View_Helper_Abstract
{    
    public function getBlnCompany() 
    {
        return $this;
    }

    public function fooBar($blnCompany)
    {
        return ucfirst($blnCompany);
    }
}

Then, you need to call your view helper as follow:

$this->getBlnCompany()->fooBar('google');
//return "Google"
