Question

This is my current function to get all users:

function get_all() {
    return $this->db->get($this->tableName)->result();
}

Now I have a function that changes the mysql DATETIME to ‘time ago’

timespan(human_to_unix($datetime),time());

How can I change all the mysql datetimes in the array that get_all produces before passing it to the controller and the view?

Secondly,
Is it correct to do this in the Model or should this be done in the Controller?

Answer 1

I would say the model is fine for doing this.

You have a number of options simply iterate over the array
e.g.

$results = $this->db->get($this->tableName)->result();
foreach($results as $key=>$value)
{
  if($key=="<name of date time field>")
   {
     $results[$key]=timespan(human_to_unix($value),time());
   }
}

return $results;

if 5.3 php
Use something like array_walk with anonymous function

$results = $this->db->get($this->tableName)->result();

    array_walk($results, function (&$v, $k) { if($k=="<name of date time field>"){$v=timespan(human_to_unix($v),time()} });
