Question

I asked Google to help me I got no luck. 🙁
Here’s the particular code that generates the error:

$this->conn->query("UPDATE tz_members SET confirm='yes' WHERE usr='".$uname."'");

The whole function is the following:

    function update_confirm_field($code) {

    $uname = $this->conn->query("SELECT usr FROM tz_members WHERE 
                     confirm='".$code."'");

    $this->conn->query("UPDATE tz_members SET confirm='yes' WHERE 
                     usr='".$uname."'");
}

Forgive me if I have missed something stupid. Can anyone tell me what’s causing the problem please???

Answer 1

The problem is that $uname is an object, not a string. You need to call one of $uname’s methods to access the data.

    function update_confirm_field($code) {

    $uname = $this->conn->query("SELECT usr FROM tz_members WHERE 
                     confirm='".$code."'");

    while ($row = $uname->fetch_assoc()) { 

    $this->conn->query("UPDATE tz_members SET confirm='yes' WHERE 
                     usr='".$row["usr"]."'");

    }

}

that should do it (or one of the above solutions).
