I'm trying to update data from mysql database use php.
I can get all data from db into table, then I click edit and I can get the data, but when I edit the form and click the submit button it's always said that the field is empty. Or sometimes it's edited into "blank row" on mysql db
heres the code:
ktgr_soal.php
<?php
include('../koneksi/koneksi.php');
if ((isset($_GET['aksi'])) && (isset($_GET['data']))) {
if ($_GET['aksi'] == 'hapus') {
$kode_ktgr = $_GET['data'];
//hapus data
$sql_ktgr = "delete from `kategori_soal`
where `id_kategori` = '$kode_ktgr'";
mysqli_query($koneksi, $sql_ktgr);
}
}

It's telling you that $upload_data['file_name'] doesn't exist.
Which I would assume is because you have not uploaded anything, then when you do - it exists and all is good.
So, you could swap out
<img alt="Your uploaded image" src="<?=base_url(). 'assets/img/' . $upload_data['file_name'];;?>">
for:
<?php if(isset( $upload_data['file_name'] )){ ?>
<img alt="Your uploaded image" src="<?=base_url(). 'assets/img/' . $upload_data['file_name'];?>">
<?php } ?>
To check if it has been set before trying to apply it.
Found the problem this should fix it in profile controller :)
function index()
{
if (!isset($details[0])){
$details = $this->user_model->get_user_by_id($this->session->userdata('uid'));
$data['uname'] = $details[0]->firstname . " " . $details[0]->lastname;
$data['uemail'] = $details[0]->email;
$this->load->view('profile_view', $data);}
