Answer 1

You are using array syntax where you need object syntax. Replace

$desig['name']

with

$desig->name

Note: you will have the same problem in those lines referring to $desig[$i] . I'm not sure what you're trying to do there, but it looks like you are blending some syntax from a for loop into your foreach loop. If I understand correctly, you simply need to drop the [$i] in each place you use it.

Answer 2

To use result of query as array say

 $result=$query->result_array();

because by default result is returned as object

Answer 3

Try this

in Model

public function get_alldesignation_model()
    {
        $query = $this->db->get('designations');
        $result=$query->result_array();//Store data as Array
        return $result;
    }

in view

<?php 
    $i=1;
    foreach($designation as $desig)
{
    ?>

    <tr>
        <td><?php echo $i  ?></td>
        <td><?php echo $desig['name']; ?></td>
        <td><a href="<?php echo base_url('index.php/designation/delete_designation/'.$desig[$i]->dkey);?>">
                <input type="button" value="Delete" class="btn btn-danger"/>
            </a>
        <td class="numeric"><a id= "<?php echo $desig[$i]->dkey; ?>"  onclick="edit_designation('<?php echo $designation[$i]->dkey; ?>')" data-target="#myModal" data-toggle="modal" style="color:#ffffff;" href="#myModal"><button class="btn blue" type="button">Edit</button>

    </tr>
    <?php
    $i++;
}
?>
