Php – Error Number: 1048 , Even though the input form has been filled correctly

I have an issue with the input in my CodeIgniter. Even though the input form has been filled correctly, Error Number: 1048 still appears. Please help with a solution for this error.

Here is the code for my view, ‘entry.php’:

<?php if($this->session->flashdata('message')) : ?>
    <div class="alert alert-success alert-dismissible fade show" role="alert">
        <?= $this->session->flashdata('message') ?>
        <button type="button" class="close" data-dismiss="alert" aria-label="Close">
            <span aria-hidden="true">&times;</span>
        </button>
    </div>
<?php endif ?>

<form action="" method="POST">

    <div class="card">
