You delete that record which is unchecked ? You can try deleting those ids that are not posted from the all records — Zeeshan

Unchecked checkbox value will not get posted, so you have to use jquery and ajax

Your checkbox

<input class="id_overview" type="checkbox" name="id_overview[]" value="<?php echo $row['id_overview']; ?>"<?php foreach ($field as $wor){ ?> <?php if($row['id_overview']==$wor['id_overview']) echo "checked";?> <?php } ?> ><?php echo $row['title']; ?>

your jquery

<script type="text/javascript">
    $(document).ready(function() {
        $("form#frm").submit(function(e) { // give a id to your form
            e.preventDefault();
            var ids = new Array();
            $('.id_overview').each(function() {
                if ($(this).is(':checked')) {
                } else {
                    ids.push($(this).val());
                }
            });
            $.ajax({
                // send ids through your ajax code
            });
        });
    });
</script>

create a new function and call it by ajax to delete the ids.

Using the jquery, we are checking the checkbox is checked or not, if uncheck then push to an array. This ids will be pass to an new function of controller using ajax.

You can try like this

<form method="post" action="<?php echo base_url(); ?>biostar/add_overview_product/<?php echo $id_product->id_product; ?>">
        <div class="box-body">
            <?php foreach ($speed as $row){ ?>
                <div class="checkbox">
                    <label>
                        <input type="hidden" name="all_id[]" value="<?php echo $row['id_overview']; ?>" />
                        <input type="checkbox" name="id_overview<?php echo $row['id_overview']; ?>" onClick="EnableSubmit3(this)" value="<?php echo $row['id_overview']; ?>"<?php foreach ($field as $wor){ ?> <?php if($row['id_overview']==$wor['id_overview']) echo "checked";?> <?php } ?> ><?php echo $row['title']; ?>
                    </label>
                </div>
            <?php } ?>
            <!-- /input-group -->
        </div>
        <div class="box-footer">
            <input value="Submit" type="submit" id="submit3" name="submit" class="btn btn-primary">
        </div>
            </form>

and in you controller

if ($this->input->post('submit')) {
foreach($all_id as $row_id)
{
     if($this->input->post('id_overview'.$row_id))
     {
           //do action where id is present
     }
     else
     {
            //do action if unchecked   by getting id $row_id
     }
}
}
