Get multiple values of checkbox in codeigniter - php

Question

I am currently doing a project. I have a checkbox( where the user will choose type of services provided by the company). When I try to post the service that was selected(for example 2 services is checked) in my controller, I am only getting one service. The question is how can I get the multiple values in my checkbox?
Note: I also tried to use foreach within my controller, I am getting some error like "Invalid argument supplied for foreach()".
View
<label>Desired Service</label> <br>
<?php foreach($services as $s):?>
<label><input type="checkbox" name="service_name[]" value="<?= $s->service_name?>"><?= $s->service_name?></label>
<br>
<?php endforeach?>
Controller
$this->form_validation->set_error_delimiters('<div class="alert alert-danger" role="alert">', '</div>');
$this->form_validation->set_rules('full_name', 'Fullname', 'required');
$this->form_validation->set_rules('email', 'Email', 'required');
$this->form_validation->set_rules('contact', 'Contact', 'required');
$this->form_validation->set_rules('date', 'Date', 'required');
$this->form_validation->set_rules('address', 'Address', 'required');
$this->form_validation->set_rules('zip_code', 'Zip Code', 'numeric|required');
$this->form_validation->set_rules('province', 'Province', 'required');
$this->form_validation->set_rules('date', 'Date', 'required');
$this->form_validation->set_rules('service_name', 'Service', 'required');
if ($this->form_validation->run() == FALSE) {
$this->index();
}
else {
$service_name = implode(', ', $_POST['service_name']);
$event = array(
'full_name' => $this->input->post('full_name'),
'email' => $this->input->post('email'),
'contact' => $this->input->post('contact'),
'address' => $this->input->post('address'),
'zip_code' => $this->input->post('zip_code'),
'state_province' => $this->input->post('province'),
'date' => $this->input->post('date'),
'service' => $service_name
);
$this->EventModel->add_event($event);
echo "<script>
window.alert('Your Desired Date is being Proccessed!');
location.href = '".site_url('/')."';
</script>";
}

Answer 1

Change from
$service_name = $_POST['service_name'];
foreach($service_name as $key =>$value)
{
echo $value;
}
die;
to
$service_name = implode(',',$_POST['service_name']);
echo $service_name;

Answer 2

I hope it will solve your problem
if (!empty($this->input->post('service_name'))) {
foreach ($this->input->post('service_name') as $key => $val) {
$data[] = array(
'service_name' => $_POST['service_name'][$key]
);
}
foreach ($data as $item) {
echo $item['service_name'];
}

Answer 3

Try:
$service_name = $this->input->post('service_name');
for($i=0;$i < count($service_name);$i++){
echo $service_name[$i];
}
