Codeigniter: Display multiple images from database for - codeigniter

Question

I'm running a real estate website. I'm trying to list all images in the database for a particular listing on their respective page. I have the following code but it just repeats the same default image instead of showing all images for that listing.
Model:
public function getDetails($listing_id)
{
$this->db->select(
'listings.listing_id AS id,
listings.account_id AS account_id,
listings.nbrhood_id AS nbrhood_id,
listings.price AS price,
listings.convertible AS convertible,
listings.available AS available,
images.file_name AS file_name,
listings.sqft AS sqft,
listings.db_tag AS db_tag,
listings.web_id AS web_id,
listings.description AS description,
bedrooms.beds_num AS beds_val,
bedrooms.beds_name AS beds_text,
bathrooms.baths_num AS baths_val,
bathrooms.baths_name AS baths_text,
nbrhoods.nbrhood_name AS nbrhood,
nbrhoods.image AS nbrhood_image,
types_listings.type_name AS type,
pets.pet_name AS pets'
);
$this->db->join('images', 'images.image_id = listings.image_id', 'left');
$this->db->join('bedrooms', 'bedrooms.beds_id = listings.beds_id');
$this->db->join('bathrooms', 'bathrooms.baths_id = listings.baths_id');
$this->db->join('nbrhoods', 'nbrhoods.nbrhood_id = listings.nbrhood_id');
$this->db->join('types_listings', 'types_listings.type_id = listings.type_id');
$this->db->join('pets', 'pets.pet_id = listings.pet_id');
$this->db->where('listings.listing_id', $listing_id);
$this->db->limit(1);
return $this->db->get($this->table_name)->row();
}
PHP:
<?php foreach ($listing AS $listing_id): ?>
<li data-image-id="<?=$image -> image_id ?>" class="uploaded-image" id="image_<?=$image -> image_id ?>">
<div class="sortableimagewrapper">
<!-- <span class="label label-inverse image-name"> </span> -->
<img src="<?=images_url('110x68/' . $listing -> file_name) ?>" alt="" width="110px" height="68px" class="img-polaroid" />

Answer 1

I don't know about your data model. You should post it here. If your data model has been done correctly, then this is the line that would change:
$this->db->join('images', 'images.image_id = listings.image_id', 'left');
to
$this->db->join('images', 'images.listing_id = listings.id');
You should store the listing ID in the Images table rather than the other way round.
EDIT:
From data model, I mean database structure. If there are n images for every single 'listing', then you need to store a reference to the 'listing ID' in the 'images' table.

Answer 2

Took over this project from someone else. Where would I add fields to the image table. Right now in CMS it shows multiple images for a listing. The code is:
<?php foreach ($images as $image): ?>
<li data-image-id="<?=$image -> image_id ?>" class="uploaded-image" id="image_<?=$image -> image_id ?>">
<div class="sortableimagewrapper">
<!-- <span class="label label-inverse image-name"> </span> -->
<img src="<?=images_url('110x68/' . $image -> file_name) ?>" alt="" width="110px" height="68px" class="img-polaroid" />
<div class="btn-group">
<button class="btn <?php
if ($image -> image_id == $listing -> image_id)
echo 'btn-warning';
?> image-default"><span class="icon-star <?php
if ($image -> image_id == $listing -> image_id)
echo 'icon-white';
?>"></span></button>
<button class="btn image-remove"><span class="icon-remove"></span></button>
</div>
</div>
</li>
<?php endforeach; ?>
</ol>
