Codeigniter controller cannot get POST data from view

Question

Before I begin, I must clarify something I'm using codeigniter 3 and I know, it's outdated but it was for a project and I even asked "can't we use a newer version" and I got a big "no it can't be used on my running on the device" was the answer. I know other users have asked this question before, but none of the solutions worked for me.

So here comes the problem, I have a view and a controller, the controller is not capturing any data from the view, here is the form code on the view

<form method="POST" action="<?php echo base_url() ?>Dashboard/tambah_matkul">
                        <div class="modal-body">
                            <div class="form-group">
                                <label for="exampleFormControlInput1">Nama mata kuliah</label>
                                <input nama="matakuliah" type="text" class="form-control" id="exampleFormControlInput4">
                            </div>
                        </div>
                        <div class="modal-footer">
                            <button type="button" class="btn btn-secondary" data-dismiss="modal">Cancel</button>
                            <button type="submit" class="btn btn-primary">submit</button>
                        </div>
                    </form>

This is the 'tambah_matkul' function on the 'Dashboard' controller

public function tambah_matkul() {
        $matakuliah = $this->input->post();
        var_dump($matakuliah);
        print_r($_POST);
    }

After I press the "Submit" button on the view, both the "$matakuliah" and $_POST variables return an empty array, which I thought was supposed to record what I put on the form and pass it to the controller ​​.

I also searched for other questions and they suggested me to modify my .htaccess file to fix it but none of them worked so I reverted it to the time before I tried any of them and here is my .htaccess Code< /p>

RewriteEngine On
RewriteBase /pemweb2
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

(I hope you don’t mind if I use some Indonesian for variable names)

Answer 1

Change your attribute nama to name, the input has no attribute like nama.

<input name="matakuliah" type="text" class="form-control" id="exampleFormControlInput4">
