CodeIgniter - validation not happens

I am doing a validation using Code Igniter. I have a simple form which used to create / update a product record. 

public function productSave($params) {
    if (!$this->validate($params)) {
        return FALSE;
    }
    $id_col_value = $params['product_id'];

    if ($id_col_value) {
        // update
        $this->db->where("product_id", $id_col_value);
        return $result = $this->db->update("product", $params);
    } else {
        // insert
        return $result = $this->db->insert("product", $params);
    }
}

My validation function looks like this,

protected function validate($params) {
    $this->form_validation->set_rules("name", "", "trim|required");
    $this->form_validation->set_data($params);
    if ($this->form_validation->run() == FALSE){
        $errors = $this->form_validation->error_array();
        if ( $errors ){
            return FALSE;
        }
    }
    return TRUE;
}

Now the problem

When inserting (when product_id is null) it validates. But when we have a product_id it does not validates.

My payload ($params) looks like this,

Array
(
    [product_id] => 1 // this is NULL when we do inserting
    [name] => Test Name
)

I can't figure out what I am doing wrong here and why the validation not work for updating. I use the same code for both cases.

Please Help! Thanks in advance!

I figure it out.

"We have to call the set_data() method before defining any validation rules."

Which is in the Documentation of CI.

So, basically, I call $this->form_validation->set_data($params); first and then, I call $this->form_validation->set_rules("name", "", "trim|required");.

This will solve the problem.

Hope this helps anyone with the same error!!!

  1. Check your params array. I have checked it using $params = array("product_id" => 34, "name" => "Test Name") & it's working perfectly.

  2. If you have no inserted data with that product_id, it will not work. Suppose you have passed product_id=3 & this id is not available in table. Then how should it work?
