Thanks very much Stephen. I kept at it and found the solution lay in
removing the 'required' and 'allowEmpty' from the 'needOne' ruleset, and
adding a 'required' => false in the view.
Here's the working solution for any one else with this problem:
The model:
public $validate = array(
'last_name'=> array(
'needOne' => array (
'rule' => 'checkOne',
'message' => 'You must enter at least a contact name or email address.'
),
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'message' => 'Alphabets and numbers only',
'allowEmpty' => TRUE
),
'between' => array(
'rule' => array('between', 2, 45),
'message' => 'Between 2 to 45 characters',
'allowEmpty' => TRUE
)
),
'email' => array(
'needOne' => array (
'rule' => 'checkOne',
'message' => 'You must enter at least a contact name or email address.'
),
'emailAddress' => array (
'rule' => 'email',
'message' => 'A valid Email address is required',
'allowEmpty' => TRUE
)
)
);
// Ensure at least the last name or email field value is provided
public function checkOne($data) {
if(!empty($this->data[$this->alias]['last_name'])
|| !empty($this->data[$this->alias]['email'])) {
return TRUE;
} else {
return FALSE;
}
}
The view/fields (I'm using Bootstrap):
echo $this->Form->input('last_name', array(
'required' => false,
'fieldset' => false,
'label' => false,
'before' => '<label class="control-label">Last Name <span
class="one-required">*</span></label>',
'class' => 'form-control',
'placeholder' => 'Last Name',
'div' => 'form-group col-sm-12',
'error' => array(
'attributes' => array(
'wrap' => 'div',
'class' => 'alert alert-danger'
)
)
)
);
echo $this->Form->input('email', array(
'required' => false,
'fieldset' => false,
'label' => false,
'before' => '<label class="control-label">Email <span
class="one-required">*</span></label>',
'after' => '',
'class' => 'form-control',
'div' => 'form-group col-sm-12 col-xs-12',
'error' => array(
'attributes' => array(
'wrap' => 'div',
'class' => 'alert alert-danger'
)
)
)
);
Thanks.
