Form insists on GET and not POST / Codeigniter 4

Question

I cannot figure out what's going on. I am testing whether a form is submitted or not by this code;

if ($this->request->getMethod() === 'post') 
{
}

I have a form per below and am using Codeigniter4;

        <!-- show the form -->
        <?php
        $form = array(
        'class'       => 'form-control border-0',
        );
        ?>
        
        <?= form_open('Admin/post/post_update', $form); ?>
            
            <?= $this->include('Admin/Post/_post_form.php') ?>
            
            <!-- show buttons -->
            <div class="form-group">
                <button class="btn btn-primary">Save</button> 
            </div>
                
        </form>
        <!-- end form here -->

For some reason, when I select the submit button and I echo out
echo $this->request->getMethod(); it says 'get'. I was expecting to read 'post'.

I read the documentation but cannot see anywhere where I can state make the submit a post instead of get.

When I view the html, it looks correct though as follows;

 <form action="https://development.example.com/Admin/post/post_create" class="form-control&#x20;border-0" method="post" accept-charset="utf-8">

Answer 1

Change the button and use <button type="submit" class="btn btn-primary">Save</button>

Also, as the previous user said, check if method="post" is present in the HTML.

Finally, can you use $_SERVER['REQUEST_METHOD'] instead of getMethod() and post the result?

Answer 2

Try for button:

<input type="submit" class="btn btn-primary" name="submit" value="Save">

Controller:

if (isset($_POST['submit'])) {}

Answer 3

I am also facing the same problem as yours, $request->getMethod() is says 'GET' and it should be 'POST'.

Code below works for me. Its return 'post' method on controller.

View:

> <?php echo form_open(base_url('/admin/post/post_update')  ,
> array('class' => 'form-horizontal form-groups-bordered validate',
> 'enctype' => 'multipart/form-data', 'method' => 'post' ));?>

Controller:

 public function post($param1 = NULL) { if($param1 == 'post_update') { $resp = $this->request->getMethod(true); return redirect()->to('/admin/post/'. $resp );}}

How to test getMethod(). The redirect url will shows :
https://www.{domain}.com/admin/post/POST
