Answer 1

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.

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
}
}
}
