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);
}
