codeigniter inside multiple checkbox - php

Question

I have small problem with my PHP code. I must insert to database multiple values but I dont have any idea how I can do this.
My View:
<?php foreach($myKidsGroupID as $row): ?>
<label><input type="checkbox" name="user_my_group_msg" value="<?php echo $row->id; ?>" class="my_group_msg pull-right"><?php echo $row->firstname; ?> <?php echo $row->lastname; ?></label><br>
<?php endforeach; ?>
And my Model looks like this:
...
elseif($checked_my_group == 1) {
foreach ( ?? ) {
$new_mail = array(
'to_user' => $this->input->post('user_my_group_msg'),
);
$this->db->insert('mailbox', $new_mail);
}
}
...rest code....
Inside my View I display all users as checkbox but If I select two persons I must INSERT two query to database. Anyone can help me?

Answer 1

simple thing is
use serialize function don't use foreach
serialize $this->input->post('user_my_group_msg')

Answer 2

try it once it will help you your View code will look as like
<?php foreach($myKidsGroupID as $row): ?>
<label><input type="checkbox" name="user_my_group_msg" value="<?php echo $row->id; ?>" class="my_group_msg pull-right"><?php echo $row->firstname; ?> <?php echo $row->lastname; ?></label><br>
<?php endforeach; ?>
Model will be corrected like this
<?php
elseif(sizeof($this->input->post('user_my_group_msg'))>=1) {
foreach ( $this->input->post('user_my_group_msg') as $value ) {
$new_mail = array(
'to_user' => $value,
);
$this->db->insert('mailbox', $new_mail);
}
}
.....rest code
?>
