passing name instead of id

#1
Hi all,
   I'm doing project for movies based website, i need to pass the genre_type instead of instead of ID.
Web URL : showtime (dot) 22web(dot) org - and menu Movies Genre.

Objective : to get the movies list based on selected genre with Pagination ., i have done it using core PHP
@ showtime (dot) 22web(dot) org/movies-genre.php?genre_type=Action

My code, @ https://gitlab.com/manigopal/ci-projects...r/Showtime [regularly updated after every changes]


Live Website @ http://cishowtime.22web.org


Pagination works fine on #Movies page @ http://cishowtime.22web.org/movies

Resource files of #Movies page :
Model file => Model_movie.php
View file => view_movies.php
Controller file => Movies.php


Issue on #MoviesGenre page @ http://cishowtime.22web.org/movies/genre/Action

Resource files of #MoviesGenre page :
Model file => Model_movie_genre.php
View file => view_movies_genre.php
Controller file => Movies_genre.php

MVC files of Movies(which works fine) & MoviesGenre(which has issue) @ https://gitlab.com/manigopal/ci-projects...r/Showtime

Your route should be:
PHP Code:
$route['movies/genre/(:any)'] = 'movies_genre/index/$1'

Wouldn't it be more simple if you just named your controller "Movies.php" with a function genre inside it that takes the $movie_genre as parameter? Then you don't need a route at all.

is this correct to pass the value ?

@Controller (Movies_genre.php) :
following lines only,
public function index($genre_type=NULL)

$data['movies_by_genre'] = $this->Model_movie_genre->movies_by_genre($genre_type);

I have

Your model returns $query->result_array();
The result is an array with each record as an associative array.
To address an element in this array, you have to use:
PHP Code:
$row['genre_type'

If your model would return $query->result();
then each record as an object. Elements are then addressed by:
PHP Code:
$row->genre_type
