I'm new to laravel and I want to submit a registration user form that when clicked, data will be sent to my database (which is already configured) and the page will be directed to the login page but when I click submit button laravel, it says
"The POST method is not supported for this route. Supported methods: GET, HEAD."
I've searched a lot but i am clueless as i don't understand what to do.
My registration view

Upon trying to log in, I got the error page cant be found. I want it to go to the home page if the session is correct. here is the error message:
404 Page Not Found
The page you requested was not found.
How can I solve the error because I have also set as needed in the routes
I think your form action should be <?php echo base_url(); ?>user/login
Also in your model you're not checking for password anywhere.
You're also not returning anything if the email is not found or more than 1 results are found -
($query->num_rows() == 1)
Model
public function login($email,$password)
{
$query = $this->db->get_where('users', array('email' => $email, 'password' => $password))->result(); // you should use row() here to return only 1 row.
return $query; // you should check the uniqueness of email on registration, not here -- not allow duplicate email on registration
}
Controller
public function login(){
$email = $_POST['email']; // $this->input->post('email');
$password = $_POST['password'];
$data = $this->Users_model->login($email, $password);
if( !empty($data) ) // if no result found it'll be empty
{
// your code
}

header('location:'.base_url().$this->index());

See, if this helps you.
In Magento 2, I have a custom login form in Header.
If a customer is on the product page for eg :
http://www.testwebsite.com/catalog/product/view/id/10
and login from header form then customer should redirect to the same product page instead of Customer Dashboard.
I have tried plugin code from this link.
Below is my custom header form code -
<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerSession = $objectManager->get('Magento\Customer\Model\Session');
$urlInterface = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Framework\UrlInterface');
$currenturl = $urlInterface->getCurrentUrl();
if(!$customerSession->isLoggedIn()) {?>
<div class="header-login-main">
<form action="<?php echo $this->getUrl('customer/account/loginPost');?>" method="post" id="login-form" novalidate="novalidate">
<input name="form_key" value="" type="hidden">
<div class="header-login" style="">
<span>Email</span>
<input name="login[username]" id="email" class="input-text" title="Email" data-validate="{required:true, 'validate-email':true}" aria-required="true" type="email">
</div>
<div class="header-login">
<span>Password</span>
<input name="login[password]" id="pass" class="input-text" title="Password" data-validate="{required:true}" aria-required="true" type="password">
</div>
<div class="header-login1">
<button type="submit" class="action login primary" name="send" id="send2"><span>Login</span>
</div>
</form>
Reset Your Password?
</div>
<?php } ?>
Plugin Code -
<?php
namespace Vendor\Module\Plugin;
class LoginPostPlugin
{
/**
* Change redirect after login to home instead of dashboard.
*
* #param \Magento\Customer\Controller\Account\LoginPost $subject
* #param \Magento\Framework\Controller\Result\Redirect $result
*/
public function afterExecute(
\Magento\Customer\Controller\Account\LoginPost $subject,
$result)
{
$result->setPath('/'); // Change this to what you want
return $result;
}
}
I want to redirect the customer to $currenturl. Link tutorial can be able to redirect to the home page. Please suggest what needs to be done to achieve to redirect the customer to the current page.
Try the below:
Header Login Form :-
<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$customerSession = $objectManager->get('Magento\Customer\Model\Session');
$urlInterface = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Framework\UrlInterface');
$currenturl = $urlInterface->getCurrentUrl();
if(!$customerSession->isLoggedIn()) {?>
<div class="header-login-main">
<form action="<?php echo $this->getUrl('customer/account/loginPost');?>" method="post" id="login-form" novalidate="novalidate">
<input name="form_key" value="" type="hidden">
<input type="hidden" name='referer' value="<?php echo $currenturl ?>">
<div class="header-login" style="">
<span>Email</span>
<input name="login[username]" id="email" class="input-text" title="Email" data-validate="{required:true, 'validate-email':true}" aria-required="true" type="email">
</div>
<div class="header-login">
<span>Password</span>
<input name="login[password]" id="pass" class="input-text" title="Password" data-validate="{required:true}" aria-required="true" type="password">
</div>
<div class="header-login1">
<button type="submit" class="action login primary" name="send" id="send2"><span>Login</span>
</div>
</form>
Reset Your Password?
</div>
<?php } ?>
Plugin Code : -
<?php
namespace Vendor\Module\Plugin;
class LoginPostPlugin
{
protected $request;
public function __construct(
\Magento\Framework\App\RequestInterface $request
) {
$this->request = $request;
}
public function getPostReferer()
{
return $this->request->getPostValue('referer');
}
/**
* Change redirect after login to home instead of dashboard.
*
* #param \Magento\Customer\Controller\Account\LoginPost $subject
* #param \Magento\Framework\Controller\Result\Redirect $result
*/
public function afterExecute(
\Magento\Customer\Controller\Account\LoginPost $subject,
$result)
{
$result->setPath($this->getPostReferer());
return $result;
}
}
Please try with the following code I have set the current url to the instant of $resultRedirect like this : $resultRedirect->setUrl($currenturl);
<?php
namespace Vendor\Module\Controller\Account;
use Magento\Customer\Model\Account\Redirect as AccountRedirect;
use Magento\Framework\App\Action\Context;
use Magento\Customer\Model\Session;
use Magento\Customer\Api\AccountManagementInterface;

use Magento\Framework\Exception\EmailNotConfirmedException;
use Magento\Framework\Exception\AuthenticationException;
use Magento\Framework\Data\Form\FormKey\Validator;
use Magento\Catalog\Api\ProductRepositoryInterface;
class LoginPost extends \Magento\Customer\Controller\Account\LoginPost {
public function execute() {
$urlInterface = \Magento\Framework\App\ObjectManager::getInstance()->get('Magento\Framework\UrlInterface');
$sku = '24-MB01'; //Edit as per your product sku
$_product = $this->productRepository->get($sku);
$currenturl = $_product->getProductUrl();
if ($this->session->isLoggedIn() || !$this->formKeyValidator->validate($this->getRequest())) {
/** #var \Magento\Framework\Controller\Result\Redirect $resultRedirect */
$resultRedirect = $this->resultRedirectFactory->create();
//$resultRedirect->setPath('home');
$resultRedirect->setUrl($currenturl);
return $resultRedirect;
}
if ($this->getRequest()->isPost()) {
$login = $this->getRequest()->getPost('login');
if (!empty($login['username']) && !empty($login['password'])) {
try {
$customer = $this->customerAccountManagement->authenticate($login['username'], $login['password']);
$this->session->setCustomerDataAsLoggedIn($customer);
$this->session->regenerateId();
} catch (EmailNotConfirmedException $e) {
$value = $this->customerUrl->getEmailConfirmationUrl($login['username']);
$message = __(
'This account is not confirmed.' .
' Click here to resend confirmation email.', $value
);
$this->messageManager->addError($message);
$this->session->setUsername($login['username']);
} catch (AuthenticationException $e) {
$message = __('Invalid login or password.');
$this->messageManager->addError($message);
$this->session->setUsername($login['username']);
} catch (\Exception $e) {
$this->messageManager->addError(__('Invalid login or password.'));
}
} else {
$this->messageManager->addError(__('A login and a password are required.'));
}
}
$resultRedirect = $this->resultRedirectFactory->create();
//$resultRedirect->setPath('home');
$resultRedirect->setUrl($currenturl);
return $resultRedirect;
}
}
If you have a plugin that receives the Magento\Customer\Controller\Account\LoginPost object you could get the referer URL like : $subject->_redirect->getRefererUrl(). Then return this URL
$productURL = $subject->_url->getUrl($subject->_redirect->getRefererUrl());
return $subject->_redirect($productURL);
I'm not 100% sure if this URL will actually be the URL you want but worth a try.
My password and username are correct, but I can't login to admin. Is there anything wrong with my controller?
This is my model:
class login_model extends CI_Model{
function cek($username, $password){
$this->db->where("username", $username);
$this->db->where("password", $password);
return $this->db->get("user_admin");
}
function getLoginData($usr, $psw){
$u = $usr;
$p = md5($psw);
$q_cek_login = $this->db->get_where('user_admin', array('username' => $u, 'password' => $p));
if(count($q_cek_login->result()) > 0){
foreach($q_cek_login->result() as $qck){
foreach($q_cek_login->result() as $qad){
$sess_data['logged_in'] = TRUE;
$sess_data['id'] = $qad->id;
$sess_data['username'] = $qad->username;
$sess_data['password'] = $qad->password;
$sess_data['email'] = $qad->email;
$sess_data['level'] = $qad->level;
$this->session->set_userdata($sess_data);
}
redirect('welcome_message');
}
}else{
$this->session->set_flashdata('result_login'. 'username dan password salah');
header('location: '. base_url(). 'login');
}
}
}
This is my controller:

parent::_construct();
if($this->session->userdata('username')){
redirect(base_url('welcome_message'));
}
$this->load->model(array('login_model'));

function index(){
$this->load->view('login');
}
function proses(){
$this->form_validation->set_rules('username', 'username', 'required|trim|xss_clean');
$this->form_validation->set_rules('password', 'password', 'required|trim|xss_clean');
if($this->form_validation->run() == FALSE){
$this->load->view('login');
}else{
$usr = $this->input->post('username');
$psw = $this->input->post('password');
$u = $usr;
$p = md5($psw);
$cek = $this->login_model->cek($u, $p);
if($cek->num_rows() > 0 ){
foreach($cek->result() as $qad){
$sess_data['id'] = $qad->id;
$sess_data['email'] = $qad->email;
$sess_data['username'] = $qad->username;
$sess_data['level']=$qad->level;
$this->session->set_userdata($sess_data);
}
$this->session->set_flashdata('success', 'login berhasil');
redirect(base_url('/'));
}else{
$this->session->set_flashdata('result_login', 'username dan password yang anda masukkan salah');
redirect(base_url('login'));
}
}
}
My view:
<div class="login-box-body">
<p class="login-box-msg">Sign in to start your session</p>

When I try to log in, I always get this error:
I don't see anything strikingly wrong with your code.
Well you are obviously hitting your last nested else which means for some reason this statement $cek->num_rows() > 0 is evaluating to false.
I assume that you are entering a proper and existing username + password combination. But to troubleshoot you can after $p = md5($psw); do:
echo 'hashed password: ' . $p . '<br>username: ' . $u; exit;
and see if the username and hashed password match something in the database, if not, you have your answer. My best guess is that you perhaps didn't store a hashed password and only plain-text one.
As a side note you should move all of your redirects and flashdata out of your model. Models should only return or throw Exceptions.
I'm the newbie in Codeigniter. I put the textbox values to session and go to next page and when i click the back button on 2nd page, then the 1st page data should be still in textbox. How can I do that? Please help me.

Load library session in construct
class Welcome extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->library('session');
}
Open your autoload.php in applications/config/autoload.php
$autoload['libraries'] = array('session');
The session data is the least of your problems.
First off, $this->load->view('pg2'); does not call your other functions in your controller, it loads a view named 'pg2'. In your question you didn't show the names of your views but if 'View 1' is a file named pg1.php in the /views folder, your controller function could look like this:
public function pg1() {
$this->session->set_userdata('page1',$this->input->get());
$this->load->view('pg1');
}
And then you have to learn how to pass data to display in views too... Try to read up on the docs, for example here's the page on how views work: https://www.codeigniter.com/user_guide/general/views.html

After I selected all my dropdown items and press submit it is working good but all the selected values are gone...
If you want to change color you have to go to the whole dropdown list again. Is it possible to keep all the selected values after submit?
Thanks in advance
Kind Regards
Joep
You are using GET requests to display each dropdown list in turn, and then using a POST request to submit your completed form. You should make sure that all the dropdowns are displayed after the POST request.
In index.php, I think you could try something like that :
<span id="result_1" style="display: none;">
<?php
if (isset($_POST['submit']) {
drop_1($_POST['drop_1']);
}
?>
</span>
...
<span id="result_2" style="display: none;">
<?php
if (isset($_POST['submit']) {
drop_2($_POST['drop_1'], $_POST['drop_2']);
}
?>
</span>
...
<span id="result_3" style="display: none;">
<?php
if (isset($_POST['submit']) {
drop_3($_POST['drop_1'], $_POST['drop_2'], $_POST['drop_3']);
}
?>
</span>
etc...
Anyway, the idea is to reuse the functions that build your dropdowns, based on the values in the $_POST.
