Question

I am using codeigniter form validation. To display form errors it uses this

 $this->data['message'] = (validation_errors() ?
     validation_errors() : 
     ($this->auth_lib->errors() ? 
         $this->auth_lib->errors() : 
         $this->session->flashdata('message')))

I don’t understand this syntax. I think it is an if else statement. It is very hard to understand.

Can anyone please convert this to a normal if else statement?

Because now i am going to change the error message format:

$this->message->set_error($msg=array('Test 1','Test 2'));
$message=$this->message->get_message();
$this->data['message']=$message;  

Anyone, please simplify the syntax. Thanks.

Answer 1

a ? b : c == if (a) {b} else {c}

if (validation_errors())
{
    $this->data['message'] = validation_errors();
}
else if ($this->auth_lib->errors())
{
    $this->data['message'] = $this->auth_lib->errors();
}
else
{
    $this->data['message'] = $this->session->flashdata('message');
}
