Question

I am using Codeigniter and Datamapper for DB Query. My controller is as follows

function fetch_interested_in()
{
    $in = new Interested_in();      
    $in -> get();
    $interested_in = array();
    foreach($in -> all as $data)
    {
        $interested_in[$data -> in_id] = $data -> in_title;
    }
    return $interested_in;
}

And my view file is as follows

    <?php foreach($interested_in as $in)

                        echo form_checkbox('in_in[]', $in -> in_id); 

    ?>

There are 3 rows in my table called Interested_in. 2 columns are there and names are in_id and in_title. When I run the code I get the following error in page at 3 places one after another.

**

A PHP Error was encountered Severity: Notice Message: Trying to get
property of non-object Filename: views/poverview.php Line Number: 137

Please let me know where am I going wrong. I’ll really be very thankful to you. Thanks in advance.

<?php foreach($interested_in as $in)

                    echo form_checkbox('in_in[]', $in); 

?>

Is enough.

Your title/id is “saved” in $in and not $in->id_id.

But in your case I guess you want:

<?php foreach(array_keys($interested_in) as $id):

      echo '<label>'.$interested_in[$id].'</label>';
      echo form_checkbox('in_in[]', $id); 

      endforeach;
?>
