What you could possibly do (maybe it's not the best), is to loop on
the single validation of the model by setting your different field
value to it :
In controller:
$this->Mark->validate = array('mark_number' => your validation); //
this is required if you have other validations in the Mark model (to
eventually process other validation before)
$fail = false;
for($i = 0; i < $nbmark; $i++)
{
$this->Mark->data['Mark']['mark_number'] = $this->data['Mark']
['mark_number'.$i];
if(!$this->Mark->validates())
{
$fail = true;
$this->Mark->invalidate('mark_number'.$i, "Mark already exists);
}
}
if(fail)
{
$this->render(..)
exit();
}
hope this helps
