Codeigniter使用模型视图和控制器

What will be the process to show to data in codeignator using Model View and Controller?

Controller

public function SecondarySchoolLevel() {
    $this->load->model('Schoolprogram_model');
    $data['progcategoryid'] = $this->Schoolprogram_model->getschoolprog(4);

    $this->load->view('SchoolPrograms', $data);
}

View

$query = $this->db->query("SELECT * from programs where progcategoryid = $progcategoryid");

foreach ($query->result_array() as $row){
?>
<tr id="r<?php echo $row["progid"]; ?>">
<td><?php echo $row["progcode"]; ?></td>
<td><?php echo $row["activities"]; ?></td>
<td><?php echo $row["description"]; ?></td>
<td><?php echo $row["session"]; ?></td>
<td><?php echo $row["hours"]; ?></td>
<td><?php echo $row["cost"]; ?></td>
<td><?php echo $row["progcategoryid"]; ?></td>
<td><?php echo $row["agefrom"]; ?></td>
<td><?php echo $row["ageto"]; ?></td>

Model

function getschoolprog($progcategoryid) {
    $this->db->where('progcategoryid', $progcategoryid);
    $query = $this->db->get('programs');
    return $query->result();
}

This is my code.

    Controller

    public function SecondarySchoolLevel() {
        $this->load->model('Schoolprogram_model');
        $data['progcategoryid'] = $this->Schoolprogram_model->getschoolprog(4);//result of your query is stored in this ($data['progcategoryid']) variable
        $this->load->view('SchoolPrograms', $data);
    }
    

    Model

    function getschoolprog($progcategoryid) {
        $this->db->select('*');
        $this->db->where('progcategoryid', $progcategoryid);
        $query = $this->db->get('programs');
        return $query->result_array();//<---- returns you an array
    }
    

    View

    foreach ($progcategoryid as $key => $row) { ?>
        <tr id='r<?php echo $row["progid"]; ?>'>
            <td><?php echo $row["progcode"]; ?></td>
            <td><?php echo $row["activities"]; ?></td>
            <td><?php echo $row["description"]; ?></td>
            <td><?php echo $row["session"]; ?></td>
            <td><?php echo $row["hours"]; ?></td>
            <td><?php echo $row["cost"]; ?></td>
            <td><?php echo $row["progcategoryid"]; ?></td>
            <td><?php echo $row["agefrom"]; ?></td>
            <td><?php echo $row["ageto"]; ?></td>
        </tr>
        <?php } ?>
