I want to store this results into another table as row inventory.
the table will look like this:

ID        inventory
1         (the result)
2         (another result)

And after I will query it back again so that I can display the result.

here’s what I have done lately.

store:

//getting the result
$inv = $this->db->get_from('table','id'=>'1')->row();
<input type="hidden" name="inventory" value="<?php print_r($inv)?>">
//storing in the new table
$this->db->insert('table2',array('inventory'=>$this->input->post('inventory')));

getting:

$inventory = $this->db->get_where('table2',array('ID'=>'1'))->row_array();
//result
array
(
      [ID] => 1
      [inventory] =>
      array
      (
            [0] => stdClass Object
            (
                 [ingredientID] => 2
                 ...... and so on

I want to display everything in the array[‘inventory’] which is an array of objects.

I’ve done this
foreach($arr[‘inventory’] as $invent):
echo $invent[‘ingredientID’];

but there’s an error in the foreach part.
error: Invalid argument supplied for foreach()

What should i do?
endforeach;

Answer 1

assuming:

$results = $this->db->get_where('table2',array('ID'=>'1'))->row_array();

you should use this to print it

foreach($results['inventory'] as $inventory)
{
    print_r($inventory->ingredientID);
}
