Object could not be converted to string?

Question

Why am I getting this error:

Catchable fatal error: Object of class Card could not be converted to string in /f5/debate/public/Card.php on line 79

Answer 1

you shouldn't put $ before property names when you access them:

public function insert() {
        $mysql = new DB(debate);
        $this->initializeInsert();
        $query = "INSERT INTO cards VALUES('$this->type','$this->tag','$this->author->last','$this->author->first','$this-$author->qualifications','$this->date->year','$this->date->month','$this->date->day','$this->title', '$this->source', '$this->text')";
        $mysql->execute($query);
    }
