Trouble adding certain number of rows with Codeigniter - php

Question

I have a script running through Codeigniter that pulls up a list of images pertaining to a certain product from the database. The max number of images per product is 10 but that is not always what is in the database. Thus, I am trying to pull from the database and complete the list of images even if it is less than 10. For instance,
I have
Image 1
Image 2
Image 3
Image 4
from the database. On the view, I am trying to still display the final six images (with blank data of course) so on the page itself it still shows the containers.
This is the code I have compiled so far from other advice and suggestions.
EDIT: My question essentially is how can I complete all 10 spots for images even if what I pull from the database is less than that as referenced in the example above?
From product model...
public function getImages($id) {
//run query
$this->db->from('images_main');
$this->db->where('images_main.product_id',$id);
$this->db->limit(10);
$this->db->order_by('img_order', 'asc');
$query = $this->db->get();
if ($query->num_rows() > 0)
{
return $query->result_array();
}else{
$this->session->set_flashdata( 'message', 'The query was not successful.' );
}
}
From view...
<ul id="sortable">
<?php
$count = count($img);
$max = 10;
$total = $max - $count;
for($t=1; $t<=$total; $t++):
$img[] = $t;
endfor;
print_r($img);
for ($i=1; $i<=10; $i++):
?>
<li class="img_list">
<div class="photo_content">
<div class="thumbnail" id="<?php echo $i; ?>"><img src="/crop.php?w=100&h=100&f=http://www.apriltwentyfive.com/product_images/regular_images/<?php echo $img[$i]['img_name'];?>"/></div>
<div class="uploads"><input type="text" name="photo_order" size="1" value="<?php echo $img[$i]['img_order']; ?>" readonly="readonly"/></div>
<div class="browse"></div>
</div>
</li>
<?php endfor; ?>
</ul>

As I understand your code, the variable $count contains the number of entries from the database.
So instead of having a for loop to 10, set it to $count (or use a foreach on $img).
Your $total variable is not the total but how many blank images there are to fill in. Have another loop for that.
Put both loops inside the <li class="img_list">...<li> tag.
<?php
$count = count($img);
$total = 10;
$difference = $total - $count;
?>
<ul id="sortable">
<?php
// Images from the database
for ($i = 0; $i <= $count - 1; $i++):
?>
<li class="img_list">
<div class="photo_content">
<div class="thumbnail" id="<?php echo $i; ?>"><img src="/crop.php?w=100&h=100&f=http://www.apriltwentyfive.com/product_images/regular_images/<?php echo $img[$i]['img_name'];?>"/></div>
<div class="uploads"><input type="text" name="photo_order" size="1" value="<?php echo $img[$i]['img_order']; ?>" readonly="readonly"/></div>
<div class="browse"></div>
</div>
</li>
<?php endfor; ?>
<?php
// Blank images
for ($i = 0; $i <= $difference - 1; $i++):
?>
<li class="img_list">
<div class="photo_content">
<div class="thumbnail">
<img src=".../path/to/blank_photo.png" alt="Title">
</div>
</li>
<!-- rest of HTML code -->
<?php endfor; ?>
</ul>
Hope this helps.
Notes:
IDs always start by 0, you should therefore start your loop at 0 and
not 1
<img> tags must have an alt property
