Codeigniter errors for model array

Question

This simple functionality driving me crazy - I'm trying to pull a row from database and pass it as array of information to my controller and same to my view - before passing this to view I need to get the slug field and redirect to domain/quotes/this-is-test to show correct information but I can't even do a basic query. Can you please help me with my lack of knowledge!

Model

  <?php  if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Quotes_model extends CI_Model{

  function __construct(){
     parent::__construct();
  }

  function get_records(){
    $data = array();
    $query = $this->db->select('*')
             ->from('quotes');

return $query->result();
}
}

Controller

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Welcome extends CI_Controller {


    public function index()
    {
        $this->load->helper('url');
        $this->load->model('quotes_model');
        $data['quote']= $this->quotes_model->get_records();
        $this->load->view('welcome_message', array('data' => $data));

    }
}

and I have done this in my view :

View

    <?php die(var_dump($data)); ?>

Error

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: data

Filename: models/quotes_model.php

Line Number: 16

array(1) { ["quote"]=> NULL }

Answer 1

try

$data['quote']= $this->quotes_model->get_records();
 $this->load->view('welcome_message', $data);

and return your result from model:-

return $query->result();

or

return $query;

Answer 2

try this

function get_records(){
$data = $this->db->select('*')
         ->from('quotes')
         ->join('authors', 'authors.id = quotes.author_id')
         ->join('genre', 'genre.id = quotes.id')
         ->order_by('id', 'RANDOM')
         ->limit(1)->row_array();
///$data = array();
return $data;


}

try ->row_array() if you want to fetch single row. If you want to fetch all records try result_array(). this will give you output in an array...

Answer 3

you need to first pull your results through result_array()

Corrected Code:

function get_records(){
    $data = array();
    $query = $this->db->select('*')
                        ->from('quotes')
                        ->join('authors', 'authors.id = quotes.author_id')
                        ->join('genre', 'genre.id = quotes.id')
                        ->order_by('id', 'RANDOM')
                        ->limit(1);
    ///$data = array();
    if ($query->num_rows()) {
        foreach ($query->result_array() as $row) {
            $data[] = $row;
        }
    }
    return $data;
}

Answer 4

you made a mistake in function

 function get_records(){
$query = $this->db->select('*')
         ->from('quotes')
         ->join('authors', 'authors.id = quotes.author_id')
         ->join('genre', 'genre.id = quotes.id')
         ->order_by('id', 'RANDOM')
         ->limit(1);
///$data = array();
return $data;

}

you return $data; this should be return

$query->result();

Answer 5

your model has an error, you are returning $data, which is not defined! add simply this:

return $query->result();

also change your controller:

$this->load->view('welcome_message', $data);

and then you get your data in your view like this:

foreach ($quote as $row){
    $id=$row->author_id;
    echo $id;
}
