Question

Can someone please help me to fix my problem here, the codes given below is under MODEL.

My problem is that the value inserted in database is 0 (literally zero) the exact value not shown on the table.

MODEL:

$prcode=$this->input->post('prcode');
$supplier=$this->input->post('supplier');
$data = array('prcode'=>$prcode,'supplier'=>$supplier);
$this->db->insert('t_approved',$data);

CONTROLLER:

$this->ARequestModel->create($data);

VIEW:

<form method = "post">
    <input type="submit"  class="btn green button-submit" onClick = "windows.location <?php echo site_url("ARequest/create");?>" value="Approved">
</form>

Answer 1

Use Code like this

Controller:

function create(){
        $prcode=$this->input->post('prcode');
        $supplier=$this->input->post('sup');
        $data = array(
        'prcode'=>$prcode,
        'supplier'=>$supplier
        );
$this->ARequestModel->create($data);
}

Model:

function create($data){
$this->db->insert('t_approved',$data);
}
