CodeIgniter - 变量未定义

Question

I put code like this in application/views/pengaduan_insert.php:

<?php echo form_dropdown('kategori',$kategori,'', $js); ?>

I have tried to define $kategori in controller and model, but it always show the same error,

A PHP Error was encountered

Severity: Notice

Message: Undefined variable: kategori

Filename: admin/pengaduan_insert.php

Line Number: 48

I have declared $kategori $kategori = $this->usermodel->ambil_kategori();

            //ekspand data
    foreach($kategori as $d) {
                $data['kategori'][0] = "-Pilih Kategori-";
                $data['kategori'][$d->id_kategori] = $d->kategori;
            }

Can anyone help me? Thanks a lot.

Answer 1

if the variable is undefined, then define it.

$kategori = array(
    'option 1',
    'option 2',
    'option 3',
);
