The pokedex database won't show in my work. Can anyone help me debug this one?
You're opening index right?
why didn't you add poke variable to index method too?
Controller code should be like this :
<?php
public function index() {
$pokemon = array(
'poke' => $this->Pokemodel->poketable()
);
$this->load->view('pokeview', $pokemon);
}
Full code :
<?php defined('BASEPATH') or exit('No direct script access allowed');
class Nav extends CI_Controller {
public function __construct() {
parent::__construct();
$this->load->helper('url');
$this->load->model('Pokemodel');
}
public function index() {
// Add this line
$pokemon = array(
'poke' => $this->Pokemodel->poketable()
);
$this->load->view('pokeview', $pokemon);
}
public function pokemonTable() {
$pokemon = array(
'poke' => $this->Pokemodel->poketable()
);
$this->load->view('pokeview', $pokemon);
}
public function insertPokemon() {
$this->load->view('insert_form');
}
public function pokemonInsert() {
$pokeName = $this->input->post('pokeName');
$typeOne = $this->input->post('typeOne');
$typeTwo = $this->input->post('typeTwo');
$this->load->model('Pokemodel');
$this->Pokemodel->pokeinsert($pokeName, $typeOne, $typeTwo);
$data['poke'] = $this->Pokemodel->poketable();
$this->load->view('pokeview', $data);
}
public function searchPokemon() {
$searchTerm = $this->input->get('search');
$this->load->model('Pokemodel');
$data['poke'] = $this->Pokemodel->searchPokemon($searchTerm);
$this->load->view('pokeview', $data);
}
public function viewPokemon($pokeName) {
$data['pokemon'] = $this->Pokemodel->get_pokemon_by_name($pokeName);
$this->load->view('view_pokemon', $data);
}
public function deletePokemon($pokeName) {
$this->Pokemodel->delete_pokemon($pokeName);
redirect('Nav/pokemonTable');
}
}
