How to add parameter in URL in CakePHP form submit? - cakephp

Please check my code:
<?php
$base_url = array('controller' => 'postads', 'action' => 'search/category:sales');
echo $this->Form->create("Filter",array('url' => $base_url, 'class' => 'filter'));
?>
<?php echo $this->Form->input('minprice',array('type'=>'text','placeholder'=>'Min','label'=>false,'value'=>100));?>

Controller
public function search(){
if(($this->request->is('post') || $this->request->is('put')) && isset($this->data['Filter'])){
//pr($this->data);exit;
foreach($this->data['Filter'] as $name => $value){
if($value){

You can try like this :
$base_url = array('controller' => 'postads', 'action' => 'search/sales/100/200');
in Controller :
public function search($category = '', $minPrice = '', $maxPrice = ''){

Your issue is that CakePHP is trying to render the 'admin_modal_edit.ctp' View template.
If you don't want CakePHP to render anything set autoRender to false:-
public function admin_modal_edit() {
$this->autoRender = false;
}
This will prevent CakePHP from looking for a View template to render.
$this->layout = null does not stop Cake from attempting to render templates. Which I suspect is what you're trying to achieve.
This error is showing because cakephp is complaining about the function admin_modal_edit for not having a view since it cannot find the admin_modal_edit.ctp in the view folder of your controller.
To fix this, add this
$this->autoRender = false
to your function admin_modal_edit to disable the rendering of view for that function.
So your function should look like this.
public function admin_modal_edit() {
/** -------------- **/
$this->autoRender = false;
/** -------------- **/
$id = $this->request->query('id');
if ($this->request->is('post') || $this->request->is('put')) {
if ($this->UserContact->save($this->request->data)) {
$this->Session->setFlash(__('The record has been saved'), 'flash/success');
$this->redirect(array('controller' => 'users', 'action' => 'view', $this->request->data['UserContact']['user_id']));
} else {
$this->Session->setFlash(__('The record could not be saved. Please, try again.'), 'flash/error');
}
} else {
if (!empty($id)) {
$options = array('conditions' => array("UserContact.{$this->UserContact->primaryKey}" => $id));
$this->request->data = $this->UserContact->find('first', $options);
}
}
}

message error : The requested address was not found on this server.
I don't think it is because of Arabic language because when you do :
echo $this->Form->label('prop_Pledge', 'إقتراح التعهد : ');
The second parameter is a text. I don't know which Cake version you're using but I think that the first field should be Part.prop_Pledge (Cake v3).
I suggest you to try to use debug() and exit to see where is the real problem or try to put remove arabic characters to see if this is the reason of you're problem.
Just a question where is your $this->Form->create() in view ?
line added to the database successfully but does not retoure to index
it displays an error message
Could you print the message error hello21 please ?
Hope this will help you.

First thing you are doing this in Dashboards controller, and you are creating data for Drprofile. If you in the end you want to do it in DashboardsController then you should change your from to this:
echo $this->Form->create('Drprofile', array(
'url' => array('controller' => 'dashboards', 'action' => 'editdrprofile')
));
This way you are telling form what action to use. But I would suggest you move that to DprofilesController and edit that data there.
One more thing, you closed your form there and you place $this->Form->input for id after it, change that.

CakePHP login by Username Or Email using Auth component

In my present system I need to login using username or email and password.
can anybody knows how to achieve this ?
My Form:
<?php echo $this->Form->create('User', array('action' => 'login'));
echo $this->Form->input('username', array('class' => 'TextField js-user-mode'));
echo $this->Form->input('password', array('class' => 'TextField'));
?>
MY AppController:
public $components = array(
'Email'=>array(),
'Auth' => array(
'loginAction' => array(
'admin' => false,
'controller' => 'users',
'action' => 'login'
),
'authError' => 'Your session has ended due to inactivity. Please login to continue.',
'authenticate' => array(
'Form' => array(
'fields' => array('username' => array('username','email')),
),
'all' => array(
'userModel' => 'User',
'scope' => array('User.status' =>array('active'))
)
)
)
);
Let me know what else i need to do..??
I'm not sure what the etiquette is on posting answers to old questions but here's what I did for this.
In my login function
$username = $this->data['User']['username'];
$password = $this->request->data['User']['password'];
$user = $this->User->findByUsername($username);
if (empty($user)) {
$user = $this->User->findByEmail($username);
if (empty($user)) {
$this->Session->setFlash(__('Incorrect Email/Username or Password'));
return;
}
$this->request->data['User']['username'] = $user['User']['username'];
}
I found following code from this url. I think this is the best in sense of simplicity. Use following code on your login action:
public function login() {
if($this->request->is('post')&&!empty($this->request->data)) {
App::Import('Utility', 'Validation');
if( isset($this->data['User']['username']) && Validation::email($this->request->data['User']['username'])) {
$this->request->data['User']['email'] = $this->request->data['User']['username'];
$this->Auth->authenticate['Form'] = array('fields' => array('username' => 'email'));
}
if($this->Auth->login()) {
/* login successful */
$this->redirect($this->Auth->redirect());
} else {
/* login unsuccessful */
}
}
}
And also use following code for login.ctp :
<?php
echo $this->form->create('User');
echo $this->form->input('username');
echo $this->form->input('password');
echo $this->form->end('Submit');
?>
Simply we can do this before your Auth login action:
$emailUsername = #$this->request->data['User']['email'];
if (!filter_var($emailUsername, FILTER_VALIDATE_EMAIL)) {
$emailFromUsername = $this->User->find('first', array('conditions' => array('User.username' => $emailUsername), 'recursive' => -1, 'fields' => array('email')));
//pr($emailFromUsername );
if (!empty($emailFromUsername)) {
$emailFromUsernameDB = $emailFromUsername['User']['email'];
} else {
$emailFromUsername = '';
}
$this->request->data['User']['email'] = $emailFromUsername;
}
Assuming you have username and email both fields in your users table
In your AppController.php
public function beforeFilter() {
if ($this->request->is('post') && $this->action == 'login') {
$username = $this->request->data['User']['username'];
if (filter_var($username, FILTER_VALIDATE_EMAIL)) {
$this->Auth->authenticate['Form']['fields']['username'] = 'email';
$this->request->data['User']['email'] = $username;
unset($this->request->data['User']['username']);
}
}
}
This code will work for CakePHP 2.x, not tested on version 3.x, you should have email field in your user's table.
You can leverage the MultipleColumn Auth adapter:
https://github.com/ceeram/Authenticate/blob/master/Controller/Component/Auth/MultiColumnAuthenticate.php
Update:
New version # https://github.com/dereuromark/cakephp-tools/blob/master/src/Auth/MultiColumnAuthenticate.php
I found this solution useful.
I have created two classes that extend FormAuthenticate:
app/Controller/Component/Auth/ClassNameAuthenticate.php and
<?php
App::uses('FormAuthenticate', 'Controller/Component/Auth');
class ClassNameAuthenticate extends FormAuthenticate {
}
app/Controller/Component/Auth/ClassNameEmailAuthenticate.php
<?php
App::uses('FormAuthenticate', 'Controller/Component/Auth');
class ClassNameEmailAuthenticate extends FormAuthenticate {
}
then in my Controller added Auth Component to $components
public $components = array(
'Session',
'Auth' => array(
'authenticate' => array(
'ClassName' =>array(
'userModel'=>'ClassName',
'fields' => array(
'username' => 'username',
),
'scope' => array('ClassName.active' => 1)
),
'ClassNameEmail' =>array(
'userModel'=>'ClassName',
'fields' => array(
'username' => 'email',
),
'scope' => array('ClassName.active' => 1)
)
)
),
);
login view: login.ctp
<div class="form">
<?php echo $this->Form->create('ClassName'); ?>
<fieldset>
<legend><?php echo __('Login'); ?></legend>
<?php
echo $this->Form->input('username');
echo $this->Form->input('password');
?>
</fieldset>
<?php echo $this->Form->end(array('label'=>__('Login'))); ?>
</div>
and login() action:
public function login(){
if ($this->Auth->loggedIn()) {
return $this->redirect($this->Auth->redirect());
}
if ($this->request->is('post')) {
//Need to duplicate field email for ClassNameEmail Auth
$this->request->data['ClassName']['email'] = $this->request->data['ClassName']['username'];
if ($this->Auth->login()) {
return $this->redirect($this->Auth->redirect());
}
$this->Session->setFlash(__('Invalid username/email or password, try again'));
}
}
I hope someone will find this useful.
this is my solution to solve that problem
public function login(){
if($this->request->is('post')){
$this->User->set($this->request->data);
if($this->User->validates()){
if(Validation::email($this->data['User']['username'])){
$this->Auth->authenticate['Form'] = array_merge($this->Auth->authenticate['Form'],array('fields'=>array('username'=>'email')));
$this->request->data['User']['email'] = $this->request->data['User']['username'];
unset($this->request->data['User']['username']);
}
if($this->Auth->login()){
$this->User->id = $this->Auth->user('id');
$this->User->saveField('last_login',time());
if($this->data['User']['remember']){
unset($this->request->data['User']['remember']);
$this->request->data['User']['password'] = Security::hash($this->request->data['User']['password'],'blowfish');
$this->Cookie->write('rememberMe',$this->request->data['User'],true,'2 days');
}
$this->redirect($this->Auth->loginRedirect);
}
$this->Session->setFlash('Invalid Username or Password entered, please try again.','default',array('class'=>'alert alert-warning'),'warning');
}
}
$this->set('title','Login Page');
}

Avoiding redirect and perssisting the session

I am trying to finish this website in cake php that was previously in regular php, but as newbie in the cakephp world.. I have found some difficulties such as these.
1) .When I click on login, it transfers me to another page although i have specified no redirects in app controller except when there is a registration. The login is at the top and its viewable through out all the pages, but if i click login, it redirects me to the login page (which i do not want).
2.) After I login, it brings in the session with the user name saying welcome 'username' but then if I go to another page, it seems like it forgets the session and brings back the inputs for the login form at the top of the page.
Here is my code
app_controller
<?php
class AppController extends Controller {
var $helpers = array('Html', 'Form', 'Javascript', 'Session');
var $components = array('Auth', 'Session');
function beforeFilter() {
$this->Auth->allow('add','get_categories','get_home', 'get_others', 'pages');
$this->Auth->autoRedirect = false;
}
}
?>
UsersController
<?php
class UsersController extends AppController {
var $uses = array("User");
var $components = array('Auth', 'Session');
function index()
{
$this->set('users', $this->User->find('all'));
$this->layout = 'master_layout';
}
function add() {
if (!empty($this->data)) {
//pass is hashed already
//->data['User']['password'] = $this->Auth->password($this->data['User']['password']);
if ($this->User->save($this->data)) {
$this->Session->setFlash('Your were registered!.');
$this->redirect(array('action' => 'get_home'));
}
}
$this->layout = 'master_layout';
}
//IF THE DATABASE IS SET UP CORRECTLY CAKE AUTHENTICATES AUTOMATICALLY NO
//LOGIC IS NEEDED FOR LOGIN http://book.cakephp.org/view/1250/Authentication
function login() {
$this->layout = 'master_layout';
if ($this->data) {
if ($this->Auth->login($this->data)) {
// Retrieve user data
$results = $this->User->find(array('User.username' => $this->data['User']['username']), array('User.active'), null, false);
$this->redirect(array('controller' => 'users', 'action' => 'login'));
}
}
$this->data['User']['password'] = '';
}
function logout() {
$this->redirect($this->Auth->logout());
}
}
?>
elements/loginform.ctp
<?php
if ($this->Session->read('Auth.User.username')):?>
<?php
echo "Welcome".' ' ;
echo $this->Session->read('Auth.User.username');
echo " ";
echo $html->link('logout', array('action'=>'logout'));
?>
<?php else : ?>
<div class="types form">
<?php echo $form->create('User', array('controller' => 'Users','action' => 'login')); ?>
<?php echo $form->input('username', array('label' => 'username')); ?>
<?php echo $form->input('password',array('type'=>'password', 'label' => 'password')) ?>
<?php echo $form->submit('Submit'); ?>
</div>
<?php endif; ?>
UPDATE
I added the following to the app_controller
<?php
class AppController extends Controller {
var $helpers = array('Html', 'Form', 'Javascript', 'Session');
var $components = array('Auth', 'Session');
function beforeFilter() {
//new addition
$this->set('userData', $this->Session->read());
$this->Auth->allow('add','get_categories','get_home', 'get_others', 'pages', '*');
$this->Auth->autoRedirect = false;
}
}
?>
WHEN I LOGIN I GET THIS ARRAY
Array ( [Config] => Array
( [userAgent] => 8f12200c2d48fa7955465842befe1c9e
[time] => 1323562284 [timeout] => 10 )
[Auth] => Array (
[User] => Array (
[id] => 63
[user_role] => 2 [
[user_fname] => test
[user_lname] => test
[user_email] => test#test.com
[user_phone] => 677-988-7777
[user_cellphone] => 555-456-9999
[user_address1] => 1st Avenue
[user_address2] =>
[user_city] => Citiland FL
[user_zip] => 55555
[username] => admin2 ) ) )
BUT WHEN I NAVIGATE TO A NEW PAGE
Array ( [Config] => Array (
[userAgent] => 8f12200c2d48fa7955465842befe1c9e
[time] => 1323562591 [timeout] => 10 ) )
ADDED PRINT_R TO elements/loginform TO SEE THE VARIABLE CONTENTS ACROSS ALL PAGES
<?php
print_r($userData);
if ($this->Session->read('Auth.User.username')):?>
<?php
echo "Welcome".' ' ;
echo $this->Session->read('Auth.User.username');
echo " ";
echo $html->link('logout', array('action'=>'logout'));
?>
<?php else : ?>
<div class="types form">
<?php echo $form->create('User', array('controller' => 'Users','action' => 'login')); ?>
<?php echo $form->input('username', array('label' => 'username')); ?>
<?php echo $form->input('password',array('type'=>'password', 'label' => 'password')) ?>
<?php echo $form->submit('Submit'); ?>
</div>
<?php endif; ?>
1) This is because in your UsersController you have a redirect after the user is logged in.
Your login function should instead read:
function login() {
$this->layout = 'master_layout';
if ($this->data) {
if ($this->Auth->login($this->data)) {
// Retrieve user data
$results = $this->User->find(array('User.username' => $this->data['User']['username']), array('User.active'), null, false);
/*This is the offending line, I've commented it out, but you could have it redirect somewhere else (it might be a good idea to redirect to the index action, for example, or just delete it:*/
//$this->redirect(array('controller' => 'users', 'action' => 'login'));
}
}
$this->data['User']['password'] = '';

As for 2), I believe it may be because you are not setting the data afterwards, so that while it exists in a tmp directory on the server (using the Session component) it is not actually being passed along to the view. So basically I think it's because you can't call Session methods in the view. Even if I'm not entirely correct about that, what I'm suggesting to do should work: Instead of calling session methods in the view, call them in the controller, set them in a variable for the view to access using $this->set();, then test against that variable in the view.
If you need to do this for ton of views and actions, you could consider adding something like this to your controller or even your app controller:
function beforeFilter() {
// Get session data for appllication use
$this->appuserstuff = $this->Session->read();
}
function beforeRender() {
// Make app variables available to view
$this->set('userData', $this->appuserstuff);
}
Alternatively, if you just need this in a couple actions, you could just set the user data in those actions with a:
$this->set('userData', $this->Session->read());
Now I'd recommend that you do a <?php debug($userData); ?> in one of your views so you can see how the data is structured in the array when it is set, so that you can user or test conditionals against. Finally, you could replace the direct calls to Session in your view with instead checks against the array of data:
Please note that I'm not sure how your specific array is structured so do a debug as recommended above and plug in your own keys for it to work:
<?php
if (!empty($userData['User'])):?>
<?php
echo "Welcome".' ' ;
echo $userData['User']['username'];
echo " ";
echo $html->link('logout', array('action'=>'logout'));
?>
<?php else : ?>
<div class="types form">
<?php echo $form->create('User', array('controller' => 'Users','action' => 'login')); ?>
<?php echo $form->input('username', array('label' => 'username')); ?>
<?php echo $form->input('password',array('type'=>'password', 'label' => 'password')) ?>
<?php echo $form->submit('Submit'); ?>
</div>
<?php endif; ?>
