String comparison fails because of value passed by datatable, codeigniter - php

Question

I am facing a really strange problem which i am debugging from past 2 hours but unable to find the solution. Before explaining the problem, let me show the code
My Controller Function is
$this->load->library('datatables');
$actionLinkBar = $this->load->view("content/updates/dt_files/action_bar", array(), TRUE);
$this->datatables
->select("id, name, status")
->where('id', $this->session_data['user_id'])
->from("t_user")
->add_column("action", $actionLinkBar, 'id, name, status');
echo $this->datatables->generate();
And the code in my action_bar view is
<?php
$status_rec = '$3';
var_dump($status_rec); // STRANGE OUTPUT - string(2) "1"
?>
<div class="action_bar" data-update-id="<?php echo '$1'; ?>">
<?php if ($status_rec == '1') { ?> // HENCE COMPARISON ALWAYS FAILS
<span>Present</span>
<?php }else { ?>
<span>Absent</span>
<?php } ?>
</div>
Now explaining the problem.. I am using Datatables with Codeigniter. I have a view template action_bar which will be displayed in one of the columns of datable in front end. The view has if/else condition based on value of status field from DB. If status feild value = 1 = Present. Else it is Absent. But though the $status_rec has value as '1' it still fails in comparison. Strange thing is on var_dumping $status_rec, i found that though it has proper value, the length is weird(2) though its single int. I even tried trimming etc but still no effect. Maybe that's why the comparison is failing. Your help is really needed :/
P.S - The DB feild that holds this value is int with length 1

I also had a similar problem solved it a bit by changing the library:
Datatables.php with if condition
changes in the 194, 196 and 440 strings
How to use:
$if = array('0' => array('if_condition'=>'$3', 'if_condition_eqv'=>'1', 'if_true'=>'<span>Present</span></div>', 'if_false'=>'<span>Absent</span></div>'));
$this->datatables->add_column("action", '<div class="action_bar" data-update-id="$1">', 'id, name, status');
BUT you have to change: ".=" On "=" (strings 497 and 504)
Should work.
I would really appreciate if someone will correct code
P.S. Sorry for my english
