Controller Code auth.php

public function register()

{

    $alphabet = '1234567890';

    $otp = array(); //remember to declare $pass as an array

    $alphaLength = strlen($alphabet) - 1; //put the length -1 in cache



    for ($i = 0; $i < 8; $i++) {

        $n = rand(0, $alphaLength);

        $otp[] = $alphabet[$n];

    }

    $newotp = implode($otp);

    // $data['otp'] = $newotp;









    $to = $this->input->post('email');

    $subject = "OTP FOR LOGIN";

    $message = '

                           Dear,  User ,<br> <br>

                           

                            Thanks You For Requesting OTP.<br><br>

                            Your Username is - ' . $to . ' And <br><br>

                            Your Password Is - <b>' . $newotp . '</b> <br><br>

                           

                            Thank you!<br><br>  

                            This is an autogenerated email. Please do not reply to this email.

                            

                            <br><br>

                           

                          ';

    $mail = $this->Others->send_email($to, $subject, $message);

    $data = $this->user_model->insert('cred', ['email' => $to], ['otp' => ($newotp)]);



    redirect(base_url() . 'auth/login');

   

}

Model code user_model.php

public function insert($table, $data = array())

{



    $this->db->insert('cred', $data);

    

        $afftectedRows = $this->db->affected_rows();

        if ($afftectedRows == 1) {

            $id = $this->db->insert_id();

            return $id;

        } else {

            return FALSE;

        }

    

}

My Answer:
= 6; $i++) {_ $n = rand(0, $alphaLength);_ $otp[] = $alphabet[$n];_ }_ $otp = implode($otp);_ $data = array('email' => $this->input->post('email'), 'otp' => $otp);_ $this->auth_model->register($data);_ // send OTP to email code here_}_Model Code auth_model.php_public function register($data)_{_ $this->db->insert('users', $data);_}In the controller code, you are generating the OTP correctly and storing it in the $otp variable. However, you are overwriting the $otp variable with the implode function, which converts the array into a string. Instead, you should store the generated OTP in a different variable before imploding it.

Here is the corrected code:

php
public function register(){
$alphabet = '1234567890';
$otpArray = array(); //remember to declare $pass as an array
$alphaLength = strlen($alphabet) - 1; //put the length -1 in cache

for ($i = 0; $i < 6; $i++) {
$n = rand(0, $alphaLength);
$otpArray[] = $alphabet[$n];
}

$otp = implode($otpArray);

$data = array('email' => $this->input->post('email'), 'otp' => $otp);
$this->auth_model->register($data);
// send OTP to email code here
}


By storing the generated OTP in the $otpArray variable before imploding it, you can now correctly store the OTP in the database.
