how to process a form with multiple checkboxes?

[eluser]k2zs[/eluser]
I am working on a form where the user will select multiple checkboxes with the same name. The values will be unique ID's from another table. I want to loop through all the checkboxex and insert into a record table.

My form is built like this:

Code:

if($subquery->num_rows()>0){
    foreach($subquery->result_array() as $plName) {
    $data .= '
    <div>- ' . $plName['plName'] . '</div>
    <div>&lt;input name="plId[]" type="checkbox" value="' . $plName['plID'] . '" checked /&gt;&lt;/div>
    <div style="clear:both;"></div>
    ';
    };

and in my controller I am only looping through the post data to see if it is working. Here is my controller function:

Code:

function submit()
    {
        //$this->output->enable_profiler(TRUE);
        
        foreach($_POST['plId'] as $plGrp) {
            echo $plGrp['plID'];
            echo '<br />';
        };
        
    }

and when I set enable_profiler to "TRUE" I see that the array is posted correctly:

Code:

$_POST['plId']       =

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
    [5] => 6
    [6] => 7
    [7] => 8
    [8] => 12
    [9] => 10
    [10] => 11
    [11] => 9
    [12] => 13
    [13] => 14
    [14] => 15
    [15] => 16
    [16] => 17
    [17] => 18
    [18] => 19
    [19] => 40
    [20] => 20
    [21] => 21
    [22] => 22
    [23] => 23
    [24] => 24
    [25] => 25
    [26] => 26
    [27] => 27
    [28] => 28
    [29] => 29
    [30] => 30
    [31] => 31
    [32] => 32
    [33] => 33
    [34] => 34
    [35] => 35
    [36] => 36
    [37] => 37
    [38] => 38
)

but if I just loop through the post data and echo the values I only get the first digit of the data in the array.

What am I doing wrong? I would eventually like to replace my echoe'd output with an insert into the database. I am using CI v2.0

function submit()
    {
        //$this->output->enable_profiler(TRUE);
        
        foreach($_POST['plId'] as $plGrp) {
            echo $plGrp; // This is not an array
            echo '<br />';
        };
        
    }
