When I upload my image in Laravel 9, I get the following error.
Call to a member function getClientOriginalExtension() on null
Controller
public function upload(Request $request)
{
$data = new food;
$image = $request->image;
$imagename = time().'.'.$image->getClientOriginalExtension();
$request->image->move('foodimage', $imagename);
$data->image = $imagename;
}

I want to upload images in brand folder but I have can`t write image data to path error.
.
So, I did this in my BrandController.php
public function store(Request $request)
{
$validated = $request->validate([
'brand_name'=>'required|unique:brands|max:55',
]);
$slug=Str::slug($request->brand_name,'-');
$data=array();
$data['brand_name']=$request->brand_name;
$data['brand_slug']=Str::slug($request->brand_name,'-');
$photo=$request->brand_logo;
$photoname=$slug.'.'.$photo->getClientOriginalExtension();
Image::make($photo)->resize(240,120)->save('public/files/brand/'.$photoname);
$data['brand_logo']='public/files/brand/'.$photoname; //public/files/brand/plus-point.jpg
DB::table('brands')->insert($data);
$notification = array('message'=>'Brand Inserted!','alert-type'=>'success');
return redirect()->back()->with($notification);
}
I am doing some experiment to make my controllers as much dynamic as I can. Let me give you a brief overview. I have a controller Logo Controller which I have set up like this:
use App\Models\Logo;
class LogoController extends Controller
{
public function add(Request $request)
{
$data['entity'] = 'logo';
$newEntityObj = new Logo;
$newEntityObj->title = $title; // set title
$newEntityObj->type = $type; // set type
$saveNewEntityData = $newEntityObj->save(); // save the entity data
------------------
-------------------
}
}
Now I made some changes like:
using a variable to denote the Logo Model.
$modelClass = "App\\Models\\" . ucfirst($data['entity']);
And then, using the $modelClass variable to execution Eloquent actions on it, like this:-
$newEntityObj = new $modelClass;
$newEntityObj->title = $title; // set title
$newEntityObj->type = $type; // set type
$saveNewEntityData = $newEntityObj->save(); // save the entity data
So the Logo Controller Class has been updated to:
use App\Models\Logo;
class LogoController extends Controller
{
public function add(Request $request)
{
$data['entity'] = 'logo';
$modelClass = "App\\Models\\" . ucfirst($data['entity']);
$newEntityObj = new $modelClass;
$newEntityObj->title = $title; // set title
$newEntityObj->type = $type; // set type
$saveNewEntityData = $newEntityObj->save(); // save the entity data
------------------
-------------------
}
}
Now I have created a Validationb Request File to use it for form validation. I am using it like this:
// Request Validation Inclusion //
use App\Http\Requests\AdminRequests\LogoValidation\LogoRequest;
public function add(LogoRequest $request)
{
--------------------------
--------------------------
}
Now instead of writing public function add(LogoRequest $request) I want to make it more dynamic. Something like this:
class LogoController extends Controller
{
public static $classEntity = 'logo';
public static $classFormattedEntity = null;
public static $classRequestVariable = null;
public function __construct()
{
$entityArray = explode('-', str_replace('_', '-', self::$classEntity));
foreach($entityArray as $keyEntity => $rowEntity)
{
if($keyEntity !== 0)
$entityArray[$keyEntity] = ucfirst($rowEntity);
}
self::$classFormattedEntity = implode('', $entityArray);
self::$classRequestVariable = "App\\Http\\Requests\\AdminRequests\\" . ucfirst(self::$classFormattedEntity) . "Validation\\" . ucfirst(self::$classFormattedEntity) . "Request";
}
public function add(self::$classRequestVariable $request)
{
..............................
..............................
}
}
The variable self::$classRequestVariable actually prints App\Http\Requests\AdminRequests\LogoValidation\LogoRequest
But when I am writing public function add(self::$classRequestVariable $request) instead of public function add(LogoRequest $request) I am getting the following error:
I am trying to perform afterAction event in the controller, but nothing is happening (the function is not called). This is code for afterAction:
public function afterAction($action, $result)
{
$result = parent::afterAction($action, $result);
$this->_logDownloadActivity();
return $result;
}
And function I am trying to call:
private function _logDownloadActivity()
{
$model = new ActivityLogsUserActivity();
$model->user_id = Yii::$app->user->identity->id;
$model->userActivityType_id = 3;
$model->buildVersion = 3333;
$model->ipAddress = $model->userIP();
$model->insert();
}
I am new on Yii framework, so please i need some help where to start.
What i need is, action and module to display a form to a user, which his will be able to edit is own profile (with profile picture), so i have 3 table
user_account || user_personal || user_general
how can i build a form that insert and update those 3 table at once?
i try this:
This is what i did, but its still not saving the data even into 1 table.
public function actionUpdate() {
$model = new ProfileUpdate();
if(isset($_POST['ProfileUpdate']))
{
$model->attributes = $_POST['ProfileUpdate'];
if($model->validate())
{
$account = new Profile();
$account->userid = Yii::app()->user->id;
$account->name = $model->name;
$account->website = $model->website;
$account->category = $model->category;
$account->save();
$this->redirect('profile');
}
}
model:
class Profile extends CActiveRecord
{
public $userid;
public $name;
public $website;
public $category;
public static function model()
{
return parent::model(__CLASS__);
}
public function tableName()
{
return 'userinfo';
}
public function primaryKey()
{
return 'id';
}
public static function userExists($user)
{
return self::model()->countByAttributes( array('username'=>$user) ) > 0;
}
}
You can use all three models in a single function
for example:
In create function
$model_account = new user_account;
$model_personal= new user_personal;
$model_general = new user_general;
$this->render('create',array(
'model_account'=>$model_account, 'model_personal' => $model_personal, 'model_general' => $model_general
));
here the all three models pass by render to create page.
in form page you can use the every model attributes as fields
Like this
echo $form->textField($model_account,'account_name');
echo $form->textField($model_personal,'email');
echo $form->textField($model_general,'address');
In create function / Update function
$model_account->attributes = $_POST['user_account'];
$model_personal->attributes = $_POST['user_personal'];
$model_general->attributes = $_POST['user_general'];
if($model_account->validate() && $model_personal->validate() && $model_general->validate())
{
$model_account->save();
$model_personal->save();
$model_general->save();
}
I was trying to pass SQL values from Model to Controller but the value couldn't be passed.
This the code in my model file:
class Has_alert extends CI_Model {
function __construct()
{
parent::__construct();
}
function __get_query() {
$sql = 'alerts_get_alerts';
$query = $this->db->query($sql);
$row = $query->first_row();
$header_data['hasAlert'] = $row->active;
}
}
And this is the code in my controller file:
class Chart extends CI_Controller {
// Default Constructor
public function __construct() {
parent::__construct();
$this->load->helper('html');
$this->load->model('Has_alert', '', TRUE);
$this->Has_alert->__get_query();
//$sql = 'alerts_get_alerts';
//$query = $this->db->query($sql);
//$row = $query->first_row();
//$header_data['hasAlert'] = $row->active;
}
public function index()
{
//Data Arrays
$this->load->helper('html');
$header_data['page_title'] = 'Title';
$header_data['tabid'] = "home";
//Load the headtop.php file and get values from data array
$this->load->view('includes/headertop.php', $header_data);
$this->load->view('homepage');
$this->load->view('includes/newfooter.php');
}
I got this error message on my view file:
A PHP Error was encountered
Severity: Notice
Message: Undefined variable: hasAlert
Filename: includes/headertop.php
Line Number: 184
Does anyone know what the problem is? Thank you.
Model
function __get_query() {
$sql = 'alerts_get_alerts';
$query = $this->db->query($sql);
$row = $query->first_row();
return $row->active;
}
Controller
public function index(){
$this->load->model("Has_alert");
//Data Arrays
$this->load->helper('html');
$header_data['page_title'] = 'Title';
$header_data['tabid'] = "home";
$header_data['hasAlert'] = $this->Has_alert->__get_query();
//Load the headtop.php file and get values from data array
$this->load->view('includes/headertop.php', $header_data);
$this->load->view('homepage');
$this->load->view('includes/newfooter.php');
}
I'm assuming that things like "alerts_get_alerts" is pseudocode.
