Updating Multiple Rows Within a Single Form

Hello everybody,

I have got 2 tables on my db: Products and Productimages

I'm trying to update ordering of the images on Productimages table which are related to a product:

My Productimages table:
    imageid  - imagepath - productid - ordering
 
I reach to the update page via product id (on url: update-product-image-order/3). This update page shows only the images related to this product (in this example, it is 3)

On this page I am calling images via a "foreach" and all images have the same 'name'.

And, no matter what I tried, I couldn't make it. 

My View: 

PHP Code:

<form role="form" method="post" action="<?php echo base_url('cp/productimageneworder'); ?>">
<?php 
                                             
foreach($images as $img) { ?>
                            
 <img class="current-imgs" src="<?php echo $img->imagepath; ?>" alt="<?php echo $img->imgdata; ?>">
 <input type="hidden" name="relatedphoto" value="<?php echo $img->imgid; ?>">
                                
<select id="ordering" name="order">
                                    
<option>Choose the new order for the photo?</option>
<option value="0" <?php if($img->ordering==0){echo 'selected';}?>>0</option>
<option value="1" <?php if($img->ordering==1){echo 'selected';}?>>1</option>
<option value="2" <?php if($img->ordering==2){echo 'selected';}?>>2</option>
<option value="3" <?php if($img->ordering==3){echo 'selected';}?>>3</option>
<option value="4" <?php if($img->ordering==4){echo 'selected';}?>>4</option>
<option value="5" <?php if($img->ordering==5){echo 'selected';}?>>5</option>
                                
</select>
                                                              
<div class="clr"></div>
                                                                
<?php } ?>

How should I set up my controller and my model? I would be grateful if you could show me the way.

Hi, your table has names like:
 Productimage:
    imageid  - imagepath - productid - ordering

but why you use 
src = echo $img->imgpath02;

from where you has that 02 number in imagepath?
this is a example how i used the foreach styntaxis in Codeigniter 3.1.1

Dear Eduardo-Peralta, thanks for your message. Actually that is not the reason for any mistake. Because I typed here wrong : Correcting my typo.

Following the tutorial here on YouTube I have made it work! But, I'm ready to hear any other solution or alternatives.

First add brackets to names:

PHP Code:

<input type="hidden" name="relatedphoto[]" value="<?php echo $img->imgid; ?>">
                                
<select id="ordering" name="order[]"> 


The Controller :

PHP Code:

 function productimageneworder(){
   
  
       $data = $this->input->post(); //first create a blank array
       
       for($i=0; $i<count($data['relatedphoto']);$i++) // as it is a foreach, we must do increment +1 until the last photo
       {
           $batch[]=array('imageid'=>$data['relatedphoto'][$i],
                        'ordering'=>$data['order'][$i]
           
           );
       }
       $result = $this->db->update_batch('productimages', $batch, 'imageid');
       if($result){
               $this->session->set_flashdata('ordering-success', 'New Ordering Has Been Done With a Great Success');
           redirect($_SERVER['HTTP_REFERER']);
       }
   
       
   
  } 


As I said, Even though I've found a solution, I'm ready to see your alternatives.
