Sorry for my bad english but i have a problem when i try to open localhost:8080/blog this message show up
Too few arguments to function App\Controllers\Blog::view(), 0 passed in C:\xampp\htdocs\baru\vendor\codeigniter4\framework\system\CodeIgniter.php on line 896 and exactly 1 expected

i cant find any solutions for this error, pls help thank you very much
Let's go over what you're telling the code to do.
First, you make a call to /blog. If you have auto-routing turned on this will put you forward to the controller named 'Blog'.
class Blog extends BaseController
And since you do not extend the URL with anything, the 'index' method will be called.
public function index()
{$data = [
'title' => 'artikel'
];
$model = new ModelsBlog();
if (!$this->validate([]))
{
$data['validation'] = $this->validator;
$data['artikel'] = $model->getArtikel();
return view('view_list',$data);
}
}
The index method sets $data to an array filled with 'title' => 'artikel'. And then fills $model with a new ModelsBlog.
class ModelsBlog extends Model
There is no __construct method defined in ModelsBlog so just the class is loaded and specific execution related to $model stops there, which is fine.
Then, the index() from Blog goes on and checks whether or not $this->validate([]) returns false. Since there's no else statement, if $this->validate([]) were to return true, code execution would stop there. So we'll assume $this->validate([]) returns false. So far so good, there's nothing weird going on with your code.
However, IF $this->validate([]) returns false, you tell the index() to return the function called view(). Normally CodeIgniter would serve you the view you set as the first parameter. But since you also have a Blog method named 'view', CodeIgniter will try to reroute te request to that method. So in other words, the actual request you're trying to make is:
Blog::view()
And since you've stated that view() receives 1 mandatory parameter, the requests triggers an error. You can solve the problem by either renaming the view() method of Blog to something like 'show()' or 'read()'. Anything else that does not conflict with the native CodeIgniter view() function would be good.
Honestly though, you are sending through two parameters in the index() function call so I'm slightly confused why the error generated states you provided 0, but I hope at least you gain some insight from my answer and you manage to fix the problem.
If anyone could provide more information regarding this, feel free to comment underneath and I'll add your information to the answer (if it gets accepted).

I create a menu table and menu seeder inside my database. However when I tried to click on the company menu on my website it saying that $menu is undefined but when I tried to change to jobs.index(this the one which is working fine) for my route it works but it will goes to the job.blade.php not company.blade.php I do not know which part is wrong inside my code.
companycontroller.php
class CompanyController extends Controller
{
public function index()
{
$data = Company::latest()->paginate(5);
return view('company.index', compact('data'))
->with('i', (request()->input('page', 1) - 1) * 5);
}
public function insert_logo(Request $request)
{
$request->validate([
'company_logo' => 'required|image|max:2048',
'company_name' => 'required'
]);
$image_file = $request->company_logo;
$image = Company::make($image_file);
Response::make($image->encode('jpeg'));
$form_data = array(
'company_logo' => $image,
'company_name' => $request->company_name,
);
Company::create($form_data);
return redirect()->back();
}
public function fetch_logo($image_id)
{
$image = Company::findOrFail($image_id);
$image_file = Company::make($image->company_logo);
$response = Response::make($image_file->encode('jpeg'));
$response->header('Content-Type', 'image/jpeg');
return $response;
}
I'm getting error from yii\web\Response when I use ajax validation.
Object of class yii\web\Response could not be converted to string
widget:
public function run()
{
$model = new Participants();
if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
Yii::$app->response->format = Response::FORMAT_JSON;
return ActiveForm::validate($model);
}
if ($model->load(Yii::$app->request->post())) {
$list = implode( ", ",$model->sections);
$model->sections = $list;
$model->save();
Yii::$app->session->setFlash(Alert::TYPE_SUCCESS, [
[
'title' => 'Congratulations!',
'text' => 'You are registered on the forum. Check out your email to get news about forum.',
'confirmButtonText' => 'Done!',
]
]);
return Yii::$app->controller->redirect(Yii::$app->request->referrer ?: Yii::$app->homeUrl);
}
return $this->render('header', [
'model' => $model,
]);
}
view of widget:
<?php $form = ActiveForm::begin();?>
...
<?= $form->field($model, 'email', ['enableAjaxValidation' => true])->textInput(['placeholder' => 'Email']); ?>
how I can solve this error? P.S. yii version - 2.0.17-dev
\yii\base\Widget::run() must return a string (all widgets basically)
All you should do within method run() is output or render content and you're attempting to return a Response object by way of return ActiveForm::validate($model); and return Yii::$app->controller->redirect(..)
i suggest you move all the code that supposed to handle form submission to it's own action
SiteController extends controller {
public function actionRegisterParticipant {
$model = new Participants();
if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
Yii::$app->response->format = Response::FORMAT_JSON;
return ActiveForm::validate($model);
}
if ($model->load(Yii::$app->request->post())) {
$list = implode(", ", $model->sections);
$model->sections = $list;
$model->save();
Yii::$app->session->setFlash(Alert::TYPE_SUCCESS, [
[
'title' => 'Congratulations!',
'text' => 'You are registered on the forum. Check out your email to get news about forum.',
'confirmButtonText' => 'Done!',
]
]);
return Yii::$app->controller->redirect(Yii::$app->request->referrer ?: Yii::$app->homeUrl);
}
// ...
}
and the form in the widget view should always point to this action:
<?php $form = ActiveForm::begin(['action' => 'site/register-participant']);?>
...
<?= $form->field($model, 'email', ['enableAjaxValidation' => true])->textInput(['placeholder' => 'Email']); ?>
Widget should return string as a result, but return Yii::$app->controller->redirect() returns Response object with configured redirection. If you want to redirect inside of widget you should use something like that:
if (Yii::$app->request->isAjax && $model->load(Yii::$app->request->post())) {
Yii::$app->controller->asJson(ActiveForm::validate($model));
Yii::$app->end();
}
// ...
Yii::$app->session->setFlash(/* ... */);
Yii::$app->controller->redirect(Yii::$app->request->referrer ?: Yii::$app->homeUrl);
Yii::$app->end();
But this smells like a bad design - widget should not be responsible for controlling application flow. It is better to handle user input in regular action/controller.
I wish to create the edit form in Silverstripe 4.2, much like this Stack Overflow's edit function that i'm looking for.
EDITED: I want to be able to have a page that is only available to the registered member of my website that they can post their class listings on the Frontend (not in CMS) as an owner, and need to have a 'edit' click that takes you to an identical form (same ClassListingForm) that lets member owner to edit/update their own class listings that they have posted. I have everything working except the edit and submit functions which I'm stuck on at the moment.
I have a link for editing the specific class listing:
Edit class listing</div>
It does redirected to 404 page not found with this url shown:
"http://.../learners/class-listings/edit/61"
Here's the code below I have so far, the ClassListingForm is working fine, just need to get the EditListingForm and doClassListing functions to work properly, and i may be doing something wrong in these codes? or is there a better way of doing the edit form properly which i'm unable to find anywhere on the search for specific on what i need as there's not much tutorial that covers the EditForm function on the SilverStripe lessons.

Thought i post this answer to share in case if others have the same issue i had.
Finally got it working and solved the issue now, have replaced whole the codes for both ClassEditForm and doUpdateClassListing methods, and also created another funcation called Edit:
public function Edit(HTTPRequest $request) {
$id = (int)$request->param('ID');
$class = ClassListings::get()->byID($id);
if (!$class || !$class->exists()) {
return ErrorPage::response_for(404);
}
$form = $this->ClassEditForm($class);
$return = $this->customise(array(
'Title' => 'Edit: ' . $class->CourseTitle,
'Form' => $form,
));
return $return = $return->renderWith(array('ClassListingPage_edit', 'Page'));
}
public function ClassEditForm() {
$id = (int)$this->urlParams['ID'];
$class = ClassListings::get()->byID($id);
$fields = new FieldList(
HiddenField::create('ID')->setValue($id),
TextField::create('CourseTitle', 'Course title:')
->setAttribute('placeholder', 'NZSL Level 1, NZSL 1A')
->setCustomValidationMessage('Please enter the course title field')
->addExtraClass('requiredField CourseTitle'),
TextField::create('CourseLocation','Region:')
->setAttribute('placeholder', 'Enter region')
->setCustomValidationMessage('Please enter the region field')
->addExtraClass('requiredField')
);
$actions = new FieldList(
FormAction::create('doUpdateClassListing')
->setTitle('Update your class listing')
->addExtraClass('btn btn-primary primary')
);
$validator = new RequiredFields([
'CourseTitle',
'CourseLocation'
]);
$form = Form::create($this, 'ClassEditForm', $fields, $actions, $validator);
if ($class) $form->loadDataFrom($class);
return $form;
}
public function doUpdateClassListing($data, Form $form) {
if($data['ID']){
$id = $data['ID'];
$class = ClassListings::get()->byID($id);
} else {
$class = ClassListings::create();
}
$form->saveInto($class);
$id = $class->write();
$form->sessionMessage('Your class listing has been updated!','good');
$this->redirect($this->Link() . "edit/".$id);
}
I want to use https://www.verot.net/php_class_upload_download.htm library in my project for resizing images. However, when I submit form it gives this error
I have loaded the library in the autoloader and I renamed library to "my_upload" and gave the same class name.
However, I do not know why this error occurs.
And here is my controller:

Where can be the problem?
imho the best way is to create a third party library for that
copy your class into your folder application/third_party/upload/
and in your controller you simply inlcude this file like:
require_once(APPPATH."third_party/upload/my_upload.php");
$objUpload = new my_upload($_FILES);
If you really want a library for that try the following:
The problem is your library gets instantiated by CI - you don't really have control over the constructor
the only way you could do is to include a "wrapper" library
e.g.
<?php
require_once(APPPATH."libraries/my_upload.php");
class Uploadwrapper_library
{
public function get($files)
{
return new my_upload($files);
}
}
in your controller you could do
$this->load->library("uploadwrapper_library");
$objMyUpload = $this->uploadwrapper_library->get($_FILES);
Well if you look at the file - system/libraries/Upload.php it's constructor requires a parameter...
public function __construct($config = array())
So with your MY_Upload class which is CI's way to allow you to override core classes, you need to follow suit with the class you are extending.
You've not shown your constructor so I don't know what you have attempted with your constructor...
I have a codeigniter form which runs some basic validation and submits data to the database. But I want to additionally alter the post data of one of the fields to use the inflector helper in order to convert the posted data to camel case before submitting to the database. How do I do this?
Here is my current form:
<?php echo form_open('instances/create') ?>
<label for="content">Content</label>
<textarea name="content"></textarea><br />
<input type="submit" name="submit" value="Create" />
</form>
Here is my current controller:
public function create(){
$this->load->helper('form');
$this->load->library('form_validation');
$this->load->helper('inflector');
$data['title'] = 'Create an instance';
$this->form_validation->set_rules('title', 'Title', 'required');
//want to camelize the 'title' here
if ($this->form_validation->run() === FALSE)
{
$this->load->view('templates/header', $data);
$this->load->view('instances/create');
$this->load->view('templates/footer');
}
else
{
$this->instances_model->set_instances();
$this->load->view('instances/success');
}
}
and here's my model:
<?php
class Instances_model extends CI_Model {
public function __construct(){
$this->load->database();
}
public function get_instances($slug = FALSE){
if ($slug === FALSE){
$query = $this->db->get('extra_instances');
return $query->result_array();
}
$query = $this->db->get_where('extra_instances', array('slug' => $slug));
return $query->row_array();
}
public function set_instances(){
$this->load->helper('url');
$slug = url_title($this->input->post('title'), 'dash', TRUE);
$data = array(
'slug' => $slug,
'title' => $this->input->post('title'),
'content' => $this->input->post('content'),
'year' => $this->input->post('year'),
'credit' => $this->input->post('credit'),
'source' => $this->input->post('source')
);
return $this->db->insert('extra_instances', $data);
}
}
I know that you can camelize a variable with the following:
echo camelize('my_dog_spot'); // Prints 'myDogSpot'
and I know that you can run custom validation like this:
$this->form_validation->set_rules('username', 'Username', 'callback_username_check');
public function username_check($str)
{
if ($str == 'test')
{
$this->form_validation->set_message('username_check', 'The {field} field can not be the word "test"');
return FALSE;
}
else
{
return TRUE;
}
}
But I'm lacking the knowledge of how to put this altogether to quickly change the POST data before submitting to the database.
Nothing too complicated, you can do it after you pass the validation, just before inserting your data array into the database:
$data = array(
'slug' => $slug,
'title' => camelize($this->input->post('title')),
// ...
