Displaying values in select box dynamically is not working in codeigniter - php

Question

I am trying to get values in select box as dynamic is not working
here is the my controller code below:
public function CreateNewAsset()
{
$data['courselist'] = $this->Dashboard_model->getDashboardCourses();
$this->form_validation->set_error_delimiters('<div class="error">', '</div>');
//Validating Name Field
$this->form_validation->set_rules('topicname', 'Topicname', 'required');
if ($this->form_validation->run() == FALSE) {
$this->load->view('template/header');
$this->load->view('Dashboard/CreateNewAsset');
$this->load->view('template/footer');
} else {
//Setting values for tabel columns
$data = array(
'courseid' => $this->input->post('courseid'),
'topicname' => $this->input->post('topicname'),
'refid' => $this->input->post('refid'),
'startdate' => $this->input->post('startdate'),
'expectedend' => $this->input->post('expectedend')
);
//Transfering data to Model
$this->Dashboard_model->assetInsert($data);
$data['message'] = 'Data Inserted Successfully';
//Loading View
$this->load->view('template/header');
$this->load->view('Dashboard/CreateNewAsset', $data);
$this->load->view('template/footer');
}
}
Here is the my view below:
<form action="<?php echo base_url();?>Dashboard/CreateNewAsset" method="post">
<div class="form-row">
<div class="col-md-3">Course:</div>
<div class="col-md-9">
<select name="courseid" class="form-control">
<option value="0">Select Course</option>
<?php foreach ($courselist as $course) { ?>
<option value="<?php echo $course->id; ?>"><?php echo $course->coursename; ?></option>
<?php } ?>
</select>
</div>
</div>
</form>
I have added both getting values and insert in the same function. is this the problem I am not getting values in drop-down can anyone help me what is the mistake

Change the insert part like this since u overriding $data:
$insert_data = array(
'courseid' => $this->input->post('courseid'),
'topicname' => $this->input->post('topicname'),
'refid' => $this->input->post('refid'),
'startdate' => $this->input->post('startdate'),
'expectedend' => $this->input->post('expectedend')
);
$this->Dashboard_model->assetInsert($insert_data);
The whole code should be like this :
NOTE : make sure u have loaded form_validation library and method getDashboardCourses return some data
public function CreateNewAsset()
{
$data['courselist'] = $this->Dashboard_model->getDashboardCourses();
$this->form_validation->set_error_delimiters('<div class="error">', '</div>');
$this->form_validation->set_rules('topicname', 'Topicname', 'required');
if ($this->form_validation->run() == FALSE) {
$this->load->view('template/header');
$this->load->view('Dashboard/CreateNewAsset',$data);
$this->load->view('template/footer');
}
else
{
$insert_data = array(
'courseid' => $this->input->post('courseid'),
'topicname' => $this->input->post('topicname'),
'refid' => $this->input->post('refid'),
'startdate' => $this->input->post('startdate'),
'expectedend' => $this->input->post('expectedend')
);
$this->Dashboard_model->assetInsert($insert_data);
$data['message'] = 'Data Inserted Successfully';
$this->load->view('template/header');
$this->load->view('Dashboard/CreateNewAsset', $data);
$this->load->view('template/footer');
}
}

Your "View" can't find the courseList variable.
You need to do add courseList to your data array before you pass it to the view with the form.
Eg:-
data['courseList'] = $this->getCourseList(); // Fetch the list of rows
