数组到字符串转换在Codeigniter中

I'm getting an " array to string conversion " error in codeigniter ` there is the function

==> Modele

public function getCodeActivationWebsite($EmailCode) {

        $this->db->select('advancedActivationWebsiteCode')->from($this->table)->where('advancedActivationEmailCode' , $EmailCode);
        $query = $this->db->get();
        return $query->result();            
    }

==> controllers

function downloadfile($codeActivation = '') {
        // Read the file's contents
        $name = $this->advanced->getCodeActivationWebsite($codeActivation).'.html';
        $data = file_get_contents(PATH_UPLOADS_ACTIVATION_WEBSITE . $name); // La path n'est pas valide 
        //getCode
        //ActivationWebsite($EmailCode)
        if (force_download($name, $data)) {
            return true;
        } else {
            return false;
        }
    }

When you call your model function getCodeActivationWebsite the data is returned as an object. Assuming your works query properly this object will contain the string that you want to access.

In your code the object is stored in the $name variable, so when you do this: file_get_contents(PATH_UPLOADS_ACTIVATION_WEBSITE . $name); you get an error.

Instead you have to identify the string in your object. For example it might be $name[0]->name. The best way to identify where the string is located is to print_r your object and locate the data.
